First, decide whether you want ncurses to replace your existing library (in - which case you'll need super-user privileges) or be installed in parallel - with it. - - The --prefix option to configure changes the root directory for installing - ncurses. The default is in subdirectories of /usr/local. Use - --prefix=/usr to replace your default curses distribution. This is the - default for Linux and BSD/OS users. - - The package gets installed beneath the --prefix directory as follows: - - In $(prefix)/bin: tic, infocmp, captoinfo, tset, - reset, clear, tput, toe - In $(prefix)/lib: libncurses*.* libcurses.a - In $(prefix)/share/terminfo: compiled terminal descriptions - In $(prefix)/include: C header files - Under $(prefix)/man: the manual pages - - Note however that the configure script attempts to locate previous - installation of ncurses, and will set the default prefix according to where - it finds the ncurses headers. - -2. Type `./configure' in the top-level directory of the distribution to - configure ncurses for your operating system and create the Makefiles. - Besides --prefix, various configuration options are available to customize - the installation; use `./configure --help' to list the available options. - - If your operating system is not supported, read the PORTABILITY section in - the file ncurses/README for information on how to create a configuration - file for your system. - - The `configure' script generates makefile rules for one or more object - models and their associated libraries: - - libncurses.a (normal) - - libcurses.a (normal, a link to libncurses.a) - This gets left out if you configure with --disable-overwrite. - - libncurses.so (shared) - - libncurses_g.a (debug) - - libncurses_p.a (profile) - - libncurses.la (libtool) - - If you do not specify any models, the normal and debug libraries will be - configured. Typing `configure' with no arguments is equivalent to: - - ./configure --with-normal --with-debug --enable-overwrite - - Typing - - ./configure --with-shared - - makes the shared libraries the default, resulting in - - ./configure --with-shared --with-normal --with-debug --enable-overwrite - - If you want only shared libraries, type - - ./configure --with-shared --without-normal --without-debug - - Rules for generating shared libraries are highly dependent upon the choice - of host system and compiler. We've been testing shared libraries on Linux - and SunOS with gcc, but more work needs to be done to make shared libraries - work on other systems. - - If you have libtool installed, you can type - - ./configure --with-libtool - - to generate the appropriate static and/or shared libraries for your - platform using libtool. - - You can make curses and terminfo fall back to an existing file of termcap - definitions by configuring with --enable-termcap. If you do this, the - library will search /etc/termcap before the terminfo database, and will - also interpret the contents of the TERM environment variable. See the - section BSD CONVERSION NOTES below. - -3. Type `make'. Ignore any warnings, no error messages should be produced. - This should compile the ncurses library, the terminfo compiler tic(1), - captoinfo(1), infocmp(1), toe(1), clear(1) tset(1), reset(1), and tput(1) - programs (see the manual pages for explanation of what they do), some test - programs, and the panels, menus, and forms libraries. - -4. Run ncurses and several other test programs in the test directory to - verify that ncurses functions correctly before doing an install that - may overwrite system files. Read the file test/README for details on - the test programs. - - NOTE: You must have installed the terminfo database, or set the - environment variable $TERMINFO to point to a SVr4-compatible terminfo - database before running the test programs. Not all vendors' terminfo - databases are SVr4-compatible, but most seem to be. Exceptions include - DEC's Digital Unix (formerly known as OSF/1). - - The ncurses program is designed specifically to test the ncurses library. - You can use it to verify that the screen highlights work correctly, that - cursor addressing and window scrolling works OK, etc. - -5. Once you've tested, you can type `make install' to install libraries, - the programs, the terminfo database and the manual pages. Alternately, you - can type `make install' in each directory you want to install. In the - top-level directory, you can do a partial install using these commands: - - 'make install.progs' installs tic, infocmp, etc... - 'make install.includes' installs the headers. - 'make install.libs' installs the libraries (and the headers). - 'make install.data' installs the terminfo data. (Note: `tic' must - be installed before the terminfo data can be - compiled). - 'make install.man' installs the manual pages. - - ############################################################################ - # CAVEAT EMPTOR: `install.data' run as root will NUKE any existing # - # terminfo database. If you have any custom or unusual entries SAVE them # - # before you install ncurses. I have a file called terminfo.custom for # - # this purpose. Don't forget to run tic on the file once you're done. # - ############################################################################ - - The terminfo(5) manual page must be preprocessed with tbl(1) before - being formatted by nroff(1). Modern man(1) implementations tend to do - this by default, but you may want to look at your version's manual page - to be sure. You may also install the manual pages after preprocessing - with tbl(1) by specifying the configure option --with-manpage-tbl. - - If the system already has a curses library that you need to keep using - for some bizarre binary-compatibility reason, you'll need to distinguish - between it and ncurses. If ncurses is installed outside the standard - directories (/usr/include and /usr/lib) then all your users will need - to use the -I option to compile programs and -L to link them. - - If you have BSD curses installed in your system and you accidentally - compile using its curses.h you'll end up with a large number of - undefined symbols at link time. _waddbytes is one of them. - - IF YOU DO NOT HAVE ROOT: Change directory to the `progs' subdirectory - and run the `capconvert' script. This script will deduce various things - about your environment and use them to build you a private terminfo tree, - so you can use ncurses applications. - - If more than one user at your site does this, the space for the duplicate - trees is wasted. Try to get your site administrators to install a system- - wide terminfo tree instead. - - See the BSD CONVERSION NOTES section below for a few more details. - -6. The c++ directory has C++ classes that are built on top of ncurses and - panels. You must have c++ (and its libraries) installed before you can - compile and run the demo. - - Use --without-cxx-binding to tell configure to not build the C++ bindings - and demo. - - If you do not have C++, you must use the --without-cxx option to tell - the configure script to not attempt to determine the type of 'bool' - which may be supported by C++. IF YOU USE THIS OPTION, BE ADVISED THAT - YOU MAY NOT BE ABLE TO COMPILE (OR RUN) NCURSES APPLICATIONS WITH C++. - -7. If you're running an older Linux, you must either (a) tell Linux that the - console terminal type is `linux' or (b) make a link to or copy of the - linux entry in the appropriate place under your terminfo directory, named - `console'. All 1.3 and many 1.2 distributions (including Yggdrasil and - Red Hat) already have the console type set to `linux'. - - The way to change the wired-in console type depends on the configuration - of your system. This may involve editing /etc/inittab, /etc/ttytype, - /etc/profile and other such files. - - Warning: this is not for the fainthearted, if you mess up your console - getty entries you can make your system unusable! However, if you are - a distribution maker, this is the right thing to do (see the note for - integrators near the end of this file). - - The easier way is to link or copy l/linux to c/console under your terminfo - directory. Note: this will go away next time you do `make install.data' - and you'll have to redo it. There is no need to have entries for all - possible screen sizes, ncurses will figure out the size automatically. - - -SUMMARY OF CONFIGURE OPTIONS: ----------------------------- - - The configure script provides a short list of its options when you type - - ./configure --help - - The --help and several options are common to all configure scripts that are - generated with autoconf. Those are all listed before the line - - --enable and --with options recognized: - - The other options are specific to this package. We list them in alphabetic - order. - - --disable-assumed-color - With ncurses 5.1, we introduced a new function, assume_default_colors() - which allows applications to specify what the default foreground and - background color are assumed to be. Most color applications use - full-screen color; but a few do not color the background. While the - assumed values can be overridden by invoking assume_default_colors(), - you may find it useful to set the assumed values to the pre-5.1 - convention, using this configure option. - - --disable-big-core - Assume machine has little memory. The configure script attempts to - determine if your machine has enough memory (about 6Mb) to compile the - terminfo database without writing portions to disk. Some allocators - return deceptive results, so you may have to override the configure - script. Or you may be building tic for a smaller machine. - - --disable-database - Use only built-in data. The ncurses libraries normally read terminfo - and termcap data from disk. You can configure ncurses to have a - built-in database, aka "fallback" entries. Embedded applications may - have no need for an external database. - - --disable-ext-funcs - Disable function-extensions. Configure ncurses without the functions - that are not specified by XSI. See ncurses/modules for the exact - list of library modules that would be suppressed. - - --disable-hashmap - Compile without hashmap scrolling-optimization code. This algorithm is - the default. - - --disable-leaks - For testing, compile-in code that frees memory that normally would not - be freed, to simplify analysis of memory-leaks. - - --disable-macros - For testing, use functions rather than macros. The program will run - more slowly, but it is simpler to debug. This makes a header file - "nomacros.h". See also the --enable-expanded option. - - --disable-overwrite - If you are installing ncurses on a system which contains another - development version of curses, or which could be confused by the loader - for another version, we recommend that you leave out the link to - -lcurses. The ncurses library is always available as -lncurses. - Disabling overwrite also causes the ncurses header files to be - installed into a subdirectory, e.g., /usr/local/include/ncurses, - rather than the include directory. This makes it simpler to avoid - compile-time conflicts with other versions of curses.h - - --disable-root-environ - Compile with environment restriction, so certain environment variables - are not available when running as root, or via a setuid/setgid - application. These are (for example $TERMINFO) those that allow the - search path for the terminfo or termcap entry to be customized. - - --disable-scroll-hints - Compile without scroll-hints code. This option is ignored when - hashmap scrolling is configured, which is the default. - - --enable-add-ons=DIR... - This is used to check if this package is a glibc add-on. This is used - only by the glibc makefiles. - - --enable-assertions - For testing, compile-in assertion code. This is used only for a few - places where ncurses cannot easily recover by returning an error code. - - --enable-broken_linker - A few platforms have what we consider a broken linker: it cannot link - objects from an archive solely by referring to data objects in those - files, but requires a function reference. This configure option - changes several data references to functions to work around this - problem. - - NOTE: With ncurses 5.1, this may not be necessary, since we are - told that some linkers interpret uninitialized global data as a - different type of reference which behaves as described above. We have - explicitly initialized all of the global data to work around the - problem. - - --enable-bsdpad - Recognize BSD-style prefix padding. Some ancient BSD programs (such as - nethack) call tputs("50") to implement delays. - - --enable-colorfgbg - Compile with experimental $COLORFGBG code. That environment variable - is set by some terminal emulators as a hint to applications, by - advertising the default foreground and background colors. During - initialization, ncurses sets color pair 0 to match this. - - --enable-const - The curses interface as documented in XSI is rather old, in fact - including features that precede ANSI C. The prototypes generally do - not make effective use of "const". When using stricter compilers (or - gcc with appropriate warnings), you may see warnings about the mismatch - between const and non-const data. We provide a configure option which - changes the interfaces to use const - quieting these warnings and - reflecting the actual use of the parameters more closely. The ncurses - library uses the symbol NCURSES_CONST for these instances of const, - and if you have asked for compiler warnings, will add gcc's const-qual - warning. There will still be warnings due to subtle inconsistencies - in the interface, but at a lower level. - - NOTE: configuring ncurses with this option may detract from the - portability of your applications by encouraging you to use const in - places where the XSI curses interface would not allow them. Similar - issues arise when porting to SVr4 curses, which uses const in even - fewer places. - - --enable-echo - Use the option --disable-echo to make the build-log less verbose by - suppressing the display of the compile and link commands. This makes - it easier to see the compiler warnings. (You can always use "make -n" - to see the options that are used). - - --enable-expanded - For testing, generate functions for certain macros to make them visible - as such to the debugger. See also the --disable-macros option. - - --enable-getcap - Use the 4.4BSD getcap code if available, or a bundled version of it to - fetch termcap entries. Entries read in this way cannot use (make - cross-references to) the terminfo tree, but it is faster than reading - /etc/termcap. - - --enable-getcap-cache - Cache translated termcaps under the directory $HOME/.terminfo - - NOTE: this sounds good - it makes ncurses run faster the second time. - But look where the data comes from - an /etc/termcap containing lots of - entries that are not up to date. If you configure with this option and - forget to install the terminfo database before running an ncurses - application, you will end up with a hidden terminfo database that - generally does not support color and will miss some function keys. - - --enable-hard-tabs - Compile-in cursor-optimization code that uses hard-tabs. We would make - this a standard feature except for the concern that the terminfo entry - may not be accurate, or that your stty settings have disabled the use - of tabs. - - --enable-no-padding - Compile-in support for the $NCURSES_NO_PADDING environment variable, - which allows you to suppress the effect of non-mandatory padding in - terminfo entries. This is the default, unless you have disabled the - extended functions. - - --enable-rpath - Use rpath option when generating shared libraries, and with some - restrictions when linking the corresponding programs. This applies - mainly to systems using the GNU linker (read the manpage). - - --enable-safe-sprintf - Compile with experimental safe-sprintf code. You may consider using - this if you are building ncurses for a system that has neither - vsnprintf() or vsprintf(). It is slow, however. - - --enable-sigwinch - Compile support for ncurses' SIGWINCH handler. If your application has - its own SIGWINCH handler, ncurses will not use its own. The ncurses - handler causes wgetch() to return KEY_RESIZE when the screen-size - changes. This option is the default, unless you have disabled the - extended functions. - - --enable-symlinks - If your system supports symbolic links, make tic use symbolic links - rather than hard links to save diskspace when writing aliases in the - terminfo database. - - --enable-tcap-names - Compile-in support for user-definable terminal capabilities. Use the - -x option of tic and infocmp to treat unrecognized terminal - capabilities as user-defined strings. This option is the default, - unless you have disabled the extended functions. - - --enable-termcap - Compile in support for reading terminal descriptions from termcap if no - match is found in the terminfo database. See also the --enable-getcap - and --enable-getcap-cache options. - - --enable-warnings - Turn on GCC compiler warnings. There should be only a few. - - --enable-widec - Compile with experimental wide-character code. This makes a different - version of the libraries (e.g., libncursesw.so), which stores - characters in 16-bits. We provide a simple UTF-8 driver and test - program to use this feature with terminals that can display UTF-8. - - NOTE: applications compiled with this configuration are not compatible - with those built for 8-bit characters. You cannot simply make a - symbolic link to equate libncurses.so with libncursesw.so - - --enable-xmc-glitch - Compile-in support experimental xmc (magic cookie) code. - - --with-ada-compiler=CMD - Specify the Ada95 compiler command (default "gnatmake") - - --with-ada-include=DIR - Tell where to install the Ada includes (default: - PREFIX/lib/ada/adainclude) - - --with-ada-objects=DIR - Tell where to install the Ada objects (default: PREFIX/lib/ada/adalib) - - --with-database=XXX - Specify the terminfo source file to install. Usually you will wish - to install ncurses' default (misc/terminfo.src). Certain systems - have special requirements, e.g, OS/2 EMX has a customized terminfo - source file. - - --with-dbmalloc - For testing, compile and link with Conor Cahill's dbmalloc library. - - --with-debug - Generate debug-libraries (default). These are named by adding "_g" - to the root, e.g., libncurses_g.a - - --with-default-terminfo-dir=XXX - Specify the default terminfo database directory. This is normally - DATADIR/terminfo, e.g., /usr/share/terminfo. - - --with-develop - Enable experimental/development options. This does not count those - that change the interface, such as --enable-widec. - - --with-dmalloc - For testing, compile and link with Gray Watson's dmalloc library. - - --with-fallbacks=XXX - Specify a list of fallback terminal descriptions which will be - compiled into the ncurses library. See CONFIGURING FALLBACK ENTRIES. - - --with-gpm - use Alessandro Rubini's GPM library to provide mouse support on the - Linux console. - - --with-install-prefix=XXX - Allows you to specify an alternate location for installing ncurses - after building it. The value you specify is prepended to the "real" - install location. This simplifies making binary packages. - - NOTE: a few systems build shared libraries with fixed pathnames; this - option probably will not work for those configurations. - - --with-libtool - Generate libraries with libtool. If this option is selected, then - it overrides all other library model specifications. - - --with-manpage-format=XXX - Tell the configure script how you would like to install man-pages. The - option value must be one of these: gzip, compress, BSDI, normal, - formatted. If you do not give this option, the configure script - attempts to determine which is the case. - - --with-manpage-renames=XXX - Tell the configure script that you wish to rename the manpages while - installing. Currently the only distribution which does this is - the Linux Debian. The option value specifies the name of a file - that lists the renamed files, e.g., $srcdir/man/man_db.renames - - --with-manpage-symlinks - Tell the configure script that you wish to make symbolic links in the - man-directory for aliases to the man-pages. This is the default, but - can be disabled for systems that provide this automatically. Doing - this on systems that do not support symbolic links will result in - copying the man-page for each alias. - - --with-manpage-tbl - Tell the configure script that you with to preprocess the manpages - by running them through tbl to generate tables understandable by - nroff. - - --with-normal - Generate normal (i.e., static) libraries (default). - - --with-profile - Generate profile-libraries These are named by adding "_p" to the root, - e.g., libncurses_p.a - - --with-rcs-ids - Compile-in RCS identifiers. Most of the C files have an identifier. - - --with-shared - Generate shared-libraries. The names given depend on the system for - which you are building, typically using a ".so" suffix, along with - symbolic links that refer to the release version. - - NOTE: Unless you override the configure script by setting the $CFLAGS - environment variable, these will not be built with the -g debugging - option. - - --with-shlib-version=XXX - Specify whether to use the release or ABI version for shared libraries. - This is normally chosen automatically based on the type of system - which you are building on. We use it for testing the configure script. - - --with-system-type=XXX - For testing, override the derived host system-type which is used to - decide things such as the linker commands used to build shared - libraries. This is normally chosen automatically based on the type of - system which you are building on. We use it for testing the configure - script. - - --with-terminfo-dirs=XXX - Specify a search-list of terminfo directories which will be compiled - into the ncurses library (default: DATADIR/terminfo) - - --with-termlib - When building the ncurses library, organize this as two parts: the - curses library (libncurses) and the low-level terminfo library - (libtinfo). This is done to accommodate applications that use only - the latter. The terminfo library is about half the size of the total. - - --without-ada - Suppress the configure script's check for Ada95, do not build the - Ada95 binding and related demo. - - --without-curses-h - Don't install the ncurses header with the name "curses.h". Rather, - install as "ncurses.h" and modify the installed headers and manpages - accordingly. - - --without-cxx - XSI curses declares "bool" as part of the interface. C++ also declares - "bool". Neither specifies the size and type of booleans, but both - insist on the same name. We chose to accommodate this by making the - configure script check for the size and type (e.g., unsigned or signed) - that your C++ compiler uses for booleans. If you do not wish to use - ncurses with C++, use this option to tell the configure script to not - adjust ncurses bool to match C++. - - --without-cxx-binding - Suppress the configure script's check for C++, do not build the - C++ binding and related demo. - - --without-progs - Tell the configure script to suppress the build of ncurses' application - programs (e.g., tic). The test applications will still be built if you - type "make", though not if you simply do "make install". - - -COMPATIBILITY WITH OLDER VERSIONS OF NCURSES: --------------------------------------------- - - Because ncurses implements the X/Open Curses Specification, its interface - is fairly stable. That does not mean the interface does not change. - Changes are made to the documented interfaces when we find differences - between ncurses and X/Open or implementations which they certify (such as - Solaris). We add extensions to those interfaces to solve problems not - addressed by the original curses design, but those must not conflict with - the X/Open documentation. - - Here are some of the major interface changes, and related problems which - you may encounter when building a system with different versions of - ncurses: - - 5.1 (July 8, 2000) - Interface changes: - - + made the extended terminal capabilities - (configure --enable-tcap-names) a standard feature. This should - be transparent to applications that do not require it. - - + removed the trace() function and related trace support from the - production library. - - + modified curses.h.in, undef'ing some symbols to avoid conflict - with C++ STL. - - Added extensions: assume_default_colors(). - - 5.0 (October 23, 1999) - Interface changes: - - + implemented the wcolor_set() and slk_color() functions. - - + move macro winch to a function, to hide details of struct ldat - - + corrected prototypes for slk_* functions, using chtype rather than - attr_t. - - + the slk_attr_{set,off,on} functions need an additional void* - parameter according to XSI. - - + modified several prototypes to correspond with 1997 version of X/Open - Curses: [w]attr_get(), [w]attr_set(), border_set() have different - parameters. Some functions were renamed or misspelled: - erase_wchar(), in_wchntr(), mvin_wchntr(). Some developers have used - attr_get(). - - Added extensions: keybound(), curses_version(). - - Terminfo database changes: - - + change translation for termcap 'rs' to terminfo 'rs2', which is - the documented equivalent, rather than 'rs1'. - - The problems are subtler in recent releases. - - a) This release provides users with the ability to define their own - terminal capability extensions, like termcap. To accomplish this, - we redesigned the TERMTYPE struct (in term.h). Very few - applications use this struct. They must be recompiled to work with - the 5.0 library. - - a) If you use the extended terminfo names (i.e., you used configure - --enable-tcap-names), the resulting terminfo database can have some - entries which are not readable by older versions of ncurses. This - is a bug in the older versions: - - + the terminfo database stores booleans, numbers and strings in - arrays. The capabilities that are listed in the arrays are - specified by X/Open. ncurses recognizes a number of obsolete and - extended names which are stored past the end of the specified - entries. - - + a change to read_entry.c in 951001 made the library do an lseek() - call incorrectly skipping data which is already read from the - string array. This happens when the number of strings in the - terminfo data file is greater than STRCOUNT, the number of - specified and obsolete or extended strings. - - + as part of alignment with the X/Open final specification, in the - 990109 patch we added two new terminfo capabilities: - set_a_attributes and set_pglen_inch). This makes the indices for - the obsolete and extended capabilities shift up by 2. - - + the last two capabilities in the obsolete/extended list are memu - and meml, which are found in most terminfo descriptions for xterm. - - When trying to read this terminfo entry, the spurious lseek() - causes the library to attempt to read the final portion of the - terminfo data (the text of the string capabilities) 4 characters - past its starting point, and reads 4 characters too few. The - library rejects the data, and applications are unable to - initialize that terminal type. - - FIX: remove memu and meml from the xterm description. They are - obsolete, not used by ncurses. (It appears that the feature was - added to xterm to make it more like hpterm). - - This is not a problem if you do not use the -x option of tic to - create a terminfo database with extended names. Note that the - user-defined terminal capabilities are not affected by this bug, - since they are stored in a table after the older terminfo data ends, - and are invisible to the older libraries. - - c) Some developers did not wish to use the C++ binding, and used the - configure --without-cxx option. This causes problems if someone - uses the ncurses library from C++ because that configure test - determines the type for C++'s bool and makes ncurses match it, since - both C++ and curses are specified to declare bool. Calling ncurses - functions with the incorrect type for bool will cause execution - errors. In 5.0 we added a configure option "--without-cxx-binding" - which controls whether the binding itself is built and installed. - - 4.2 (March 2, 1998) - Interface changes: - - + correct prototype for termattrs() as per XPG4 version 2. - - + add placeholder prototypes for color_set(), erasewchar(), - term_attrs(), wcolor_set() as per XPG4 version 2. - - + add macros getcur[xy] getbeg[xy] getpar[xy], which are defined in - SVr4 headers. - - New extensions: keyok() and define_key(). - - Terminfo database changes: - - + corrected definition in curses.h for ACS_LANTERN, which was 'I' - rather than 'i'. - - 4.1 (May 15, 1997) - - We added these extensions: use_default_colors(). Also added - configure option --enable-const, to support the use of const where - X/Open should have, but did not, specify. - - The terminfo database content changed the representation of color for - most entries that use ANSI colors. SVr4 curses treats the setaf/setab - and setf/setb capabilities differently, interchanging the red/blue - colors in the latter. - - 4.0 (December 24, 1996) - - We bumped to version 4.0 because the newly released dynamic loader - (ld.so.1.8.5) on Linux did not load shared libraries whose ABI and REL - versions were inconsistent. At that point, ncurses ABI was 3.4 and the - REL was 1.9.9g, so we made them consistent. - - 1.9.9g (December 1, 1996) - - This fixed most of the problems with 1.9.9e, and made these interface - changes: - - + remove tparam(), which had been provided for compatibility with - some termcap. tparm() is standard, and does not conflict with - application's fallback for missing tparam(). - - + turn off hardware echo in initscr(). This changes the sense of the - echo() function, which was initialized to echoing rather than - nonechoing (the latter is specified). There were several other - corrections to the terminal I/O settings which cause applications to - behave differently. - - + implemented several functions (such as attr_on()) which were - available only as macros. - - + corrected several typos in curses.h.in (i.e., the mvXXXX macros). - - + corrected prototypes for delay_output(), - has_color, immedok() and idcok(). - - + corrected misspelled getbkgd(). Some applications used the - misspelled name. - - + added _yoffset to WINDOW. The size of WINDOW does not impact - applications, since they use only pointers to WINDOW structs. - - These changes were made to the terminfo database: - - + removed boolean 'getm' which was available as an extended name. - - We added these extensions: wresize(), resizeterm(), has_key() and - mcprint(). - - 1.9.9e (March 24, 1996) - - not recommended (a last-minute/untested change left the forms and - menus libraries unusable since they do not repaint the screen). - Foreground/background colors are combined incorrectly, working properly - only on a black background. When this was released, the X/Open - specification was available only in draft form. - - Some applications (such as lxdialog) were "fixed" to work with the - incorrect color scheme. - - -IF YOU ARE A SYSTEM INTEGRATOR: ------------------------------- - - Beginning with 1.9.9, the ncurses distribution includes both a tset - utility and /usr/share/tabset directory. If you are installing ncurses, - it is no longer either necessary or desirable to install tset-jv. - - Configuration and Installation: - - Configure with --prefix=/usr to make the install productions put - libraries and headers in the correct locations (overwriting any - previous curses libraries and headers). This will put the terminfo - hierarchy under /usr/share/terminfo; you may want to override this with - --datadir=/usr/share/misc; terminfo and tabset are installed under the - data directory. - - Please configure the ncurses library in a pure-terminfo mode; that - is, with the --disable-termcap option. This will make the ncurses - library smaller and faster. The ncurses library includes a termcap - emulation that queries the terminfo database, so even applications - that use raw termcap to query terminal characteristics will win - (providing you recompile and relink them!). - - If you must configure with termcap fallback enabled, you may also - wish to use the --enable-getcap option. This option speeds up - termcap-based startups, at the expense of not allowing personal - termcap entries to reference the terminfo tree. See the code in - ncurses/tinfo/read_termcap.c for details. - - Note that if you have $TERMCAP set, ncurses will use that value - to locate termcap data. In particular, running from xterm will - set $TERMCAP to the contents of the xterm's termcap entry. - If ncurses sees that, it will not examine /etc/termcap. - - Keyboard Mapping: - - The terminfo file assumes that Shift-Tab generates \E[Z (the ECMA-48 - reverse-tabulation sequence) rather than ^I. Here are the loadkeys -d - mappings that will set this up: - - keycode 15 = Tab Tab - alt keycode 15 = Meta_Tab - shift keycode 15 = F26 - string F26 ="\033[Z" - - Naming the Console Terminal - - In various Linuxes (and possibly elsewhere) there has been a practice - of designating the system console driver type as `console'. Please - do not do this any more! It complicates peoples' lives, because it - can mean that several different terminfo entries from different - operating systems all logically want to be called `console'. - - Please pick a name unique to your console driver and set that up - in the /etc/inittab table or local equivalent. Send the entry to the - terminfo maintainer (listed in the misc/terminfo file) to be included - in the terminfo file, if it's not already there. See the - term(7) manual page included with this distribution for more on - conventions for choosing type names. - - Here are some recommended primary console names: - - linux -- Linux console driver - freebsd -- FreeBSD - netbsd -- NetBSD - bsdos -- BSD/OS - - If you are responsible for integrating ncurses for one of these - distribution, please either use the recommended name or get back - to us explaining why you don't want to, so we can work out nomenclature - that will make users' lives easier rather than harder. - - -RECENT XTERM VERSIONS: ---------------------- - - The terminfo database file included with this distribution assumes you - are running an XFree86 xterm based on X11R6 (i.e., xterm-r6). The - earlier X11R5 entry (xterm-r5) is provided as well. - - If you are running XFree86 version 3.2 (actually 3.1.2F and up), you - should consider using the xterm-xf86-v32 (or later, the most recent - version is always named "xterm-xfree86") entry, which adds ANSI color - and the VT220 capabilities which have been added in XFree86. If you - are running a mixed network, however, where this terminal description - may be used on an older xterm, you may have problems, since - applications that assume these capabilities will produce incorrect - output on the older xterm (e.g., highlighting is not cleared). - - -CONFIGURING FALLBACK ENTRIES: ----------------------------- - - In order to support operation of ncurses programs before the terminfo - tree is accessible (that is, in single-user mode or at OS installation - time) the ncurses library can be compiled to include an array of - pre-fetched fallback entries. - - These entries are checked by setupterm() only when the conventional - fetches from the terminfo tree and the termcap fallback (if configured) - have been tried and failed. Thus, the presence of a fallback will not - shadow modifications to the on-disk entry for the same type, when that - entry is accessible. - - By default, there are no entries on the fallback list. After you - have built the ncurses suite for the first time, you can change - the list (the process needs infocmp(1)). To do so, use the script - MKfallback.sh. A configure script option --with-fallbacks does this - (it accepts a comma-separated list of the names you wish, and does - not require a rebuild). - - If you wanted (say) to have linux, vt100, and xterm fallbacks, you - would use the commands - - cd ncurses; - MKfallback.sh linux vt100 xterm >fallback.c - - Then just rebuild and reinstall the library as you would normally. - You can restore the default empty fallback list with - - MKfallback.sh >fallback.c - - The overhead for an empty fallback list is one trivial stub function. - Any non-empty fallback list is const-ed and therefore lives in sharable - text space. You can look at the comment trailing each initializer in - the generated ncurses/fallback.c file to see the core cost of the - fallbacks. A good rule of thumb for modern vt100-like entries is that - each one will cost about 2.5K of text space. - - -BSD CONVERSION NOTES: --------------------- - - If you need to support really ancient BSD programs, you probably - want to configure with the --enable-bsdpad option. What this does - is enable code in tputs() that recognizes a numeric prefix on a - capability as a request for that much trailing padding in milliseconds. - There are old BSD programs that do things like tputs("50"). - - (If you are distributing ncurses as a support-library component of - an application you probably want to put the remainder of this section - in the package README file.) - - The following note applies only if you have configured ncurses with - --enable-termcap. - -------------------------------- CUT HERE -------------------------------- - -If you are installing this application privately (either because you -have no root access or want to experiment with it before doing a root -installation), there are a couple of details you need to be aware of. -They have to do with the ncurses library, which uses terminfo rather -than termcap for describing terminal characteristics. - -Though the ncurses library is terminfo-based, it will interpret your -TERMCAP variable (if present), any local termcap files you reference -through it, and the system termcap file. However, in order to avoid -slowing down your application startup, it will only do this once per -terminal type! - -The first time you load a given terminal type from your termcap -database, the library initialization code will automatically write it -in terminfo format to a subdirectory under $HOME/.terminfo. After -that, the initialization code will find it there and do a (much -faster) terminfo fetch. - -Usually, all this means is that your home directory will silently grow -an invisible .terminfo subdirectory which will get filled in with -terminfo descriptions of terminal types as you invoke them. If anyone -ever installs a global terminfo tree on your system, this will quietly -stop happening and your $HOME/.terminfo will become redundant. - -The objective of all this logic is to make converting from BSD termcap -as painless as possible without slowing down your application (termcap -compilation is expensive). - -If you don't have a TERMCAP variable or custom personal termcap file, -you can skip the rest of this dissertation. - -If you *do* have a TERMCAP variable and/or a custom personal termcap file -that defines a terminal type, that definition will stop being visible -to this application after the first time you run it, because it will -instead see the terminfo entry that it wrote to $HOME/terminfo the -first time around. - -Subsequently, editing the TERMCAP variable or personal TERMCAP file -will have no effect unless you explicitly remove the terminfo entry -under $HOME/terminfo. If you do that, the entry will be recompiled -from your termcap resources the next time it is invoked. - -To avoid these complications, use infocmp(1) and tic(1) to edit the -terminfo directory directly. - -------------------------------- CUT HERE -------------------------------- - -USING NCURSES WITH AFS: - AFS treats each directory as a separate logical filesystem, you - can't hard-link across them. The --enable-symlinks option copes - with this by making tic use symbolic links. - -USING NCURSES WITH EMACS: - GNU Emacs has its own termcap support. By default, it uses a mixture - of those functions and code linked from the host system's libraries. - You need to foil this and shut out the GNU termcap library entirely. - - In order to do this, hack the Linux config file (s/linux.h) to contain - a #define TERMINFO and set the symbol LIBS_TERMCAP to "-lncurses". - - We have submitted such a change for the 19.30 release, so it may - already be applied in your sources -- check for the #define TERMINFO. - -USING NCURSES WITH GPM: - Ncurses 4.1 and up can be configured to use GPM (General Purpose Mouse) - which is used on Linux console. Be aware that GPM is commonly - installed as a shared library which contains a wrapper for the curses - wgetch() function (libcurses.o). Some integrators have simplified - linking applications by combining all or part of libcurses.so (the BSD - curses) into the libgpm.so file, producing symbol conflicts with - ncurses (specifically the wgetch function). You may be able to work - around this problem by linking as follows: - - cc -o foo foo.o -lncurses -lgpm -lncurses - - but the linker may not cooperate, producing mysterious errors. - A patched version of gpm is available: - - dickey.his.com:/ncurses/gpm-1.10-970125.tar.gz - - This patch is incorporated in gpm 1.12; however some integrators - are slow to update this library. Current distributions of gpm can - be configured properly using the --without-curses option. - -BUILDING NCURSES WITH A CROSS-COMPILER - Ncurses can be built with a cross-compiler. Some parts must be built - with the host's compiler since they are used for building programs - (e.g., ncurses/make_hash and ncurses/make_keys) that generate tables - that are compiled into the ncurses library. You should set the - BUILD_CC environment variable to your host's compiler, and run the - configure script configuring for the cross-compiler. - - Note that all of the generated source-files which are part of ncurses - will be made if you use - - make sources - - This would be useful in porting to an environment which has little - support for the tools used to generate the sources, e.g., sed, awk and - Bourne-shell. - -BUGS: - Send any feedback to the ncurses mailing list at - bug-ncurses@gnu.org. To subscribe send mail to - bug-ncurses-request@gnu.org with body that reads: - subscribe ncurses <your-email-address-here> - - The Hacker's Guide in the doc directory includes some guidelines - on how to report bugs in ways that will get them fixed most quickly. |
