It is a bourne shell -dnl script which autoconf pre-processes with the m4 preprocessor to -dnl expand autoconf-defined m4 macros such as AC_INIT(). The -dnl following line just initializes autoconf. Autoconf interprets the -dnl single argument as the name of an arbitrary file, which it uses to -dnl ensure that it is being run correctly from the directory which -dnl contains the libtecla source code. - -AC_INIT(getline.c) - -dnl Here we set the major version number of the tecla library. -dnl Incrementing this number implies that a change has been made to -dnl the library's public interface, which makes it binary incompatible -dnl with programs that were linked with previous shared versions of -dnl the tecla library. Incompatible changes of this type should be -dnl avoided at all costs, so it is hoped that the major version number -dnl won't ever have to change. The major version number must be a -dnl small integer number, preferably a single numeric digit. - -AC_SUBST(MAJOR_VER) -MAJOR_VER="1" - -dnl Set the minor version number of the tecla library. This number -dnl should be incremented by one whenever additional functionality, -dnl such as new functions or modules, are added to the library. The -dnl idea is that a program that was linked with a shared library of -dnl the same major version number, but a lower minor version number, -dnl will continue to function when the run-time loader links it -dnl against the updated version. The minor version number must be a -dnl small integer number, which should be reset to 0 whenever the -dnl major version number is incremented. - -AC_SUBST(MINOR_VER) -MINOR_VER="4" - -dnl Set the micro version number of the tecla library. This is -dnl incremented whenever modifications to the library are made which -dnl make no changes to the public interface, but which fix bugs and/or -dnl improve the behind-the-scenes implementation. The micro version -dnl number should be reset to 0 whenever the minor version number is -dnl incremented. The micro version number must be a small integer -dnl number. - -AC_SUBST(MICRO_VER) -MICRO_VER="1" - -dnl The AC_PROG_CC line looks for a C compiler, and if gcc is chosen, -dnl sets the $GCC shell variable to "yes". Make sure that CFLAGS is -dnl set to something first, to prevent AC_PROG_CC from substituting -g -dnl for the optimization level. - -CFLAGS="$CFLAGS" -AC_PROG_CC - -dnl Apparently not all implementations of the 'make' command define -dnl the MAKE variable. The following directive creates a variable -dnl called SET_MAKE which when expanded in a makefile is either empty -dnl if the local 'make' command was found to define the MAKE variable, -dnl or contains an assignment which will give the MAKE variable the -dnl value 'make'. - -AC_PROG_MAKE_SET - -dnl The following directive causes autoconf to see if symbolic links -dnl are supported on the current filesystem. If so, it sets the -dnl variable LN_S to "ln -s". Otherwise it sets LN_S to just "ln". -dnl This allows us to create symbolic links where possible, but falls -dnl back to creating hard links where symbolic links aren't available. - -AC_PROG_LN_S - -dnl The following macro searches for the best implementation of awk -dnl on the host system, and records it in the AWK shell variable. - -AC_PROG_AWK - -dnl If ranlib is needed on the target system, the RANLIB make variable -dnl is set to ranlib. Otherwise it is set to :, which is the do-nothing -dnl command of the bourne shell. - -AC_PROG_RANLIB - -dnl The following directive tells autoconf to figure out the target -dnl system type and assign a canonical name for this to the $target -dnl shell variable. This is used below in the target-specific case -dnl statement. - -AC_CANONICAL_SYSTEM - -dnl In early versions of Solaris, some libraries are in /usr/ccs/lib, -dnl where gcc doesn't look. The tests below for the curses library -dnl would thus fail without this directory being added to the search -dnl path. We thus add it here before the tests. Note that in the -dnl following, since [ and ] are m4 quotes, and m4 will remove the -dnl outermost quotes when it processes this file, we have to double -dnl them up here to get [0-6] to appear in the output configure -dnl script. - -case $target in -*-sun-solaris2.[[0-6]]|*-sun-solaris2.[[0-6]].*) - LIBS="$LIBS -L/usr/ccs/lib" - ;; -esac - -dnl The following lines look for terminfo functions in the normal -dnl curses library. If not found, they are searched for in the GNU -dnl ncurses library. If the terminfo functions still aren't found, -dnl then termcap functions are searched for in the curses library. If -dnl either set of functions is found, the corresponding variable -dnl USE_TERMINFO or USE_TERMCAP is arranged to be defined in CFLAGS, -dnl via the exported DEFINES shell variable, and the library in which -dnl they were found is appended to the LIBS shell variable. - -AC_CHECK_LIB(curses, tigetstr, [ - AC_DEFINE(USE_TERMINFO) - LIBS="$LIBS -lcurses" -], [AC_CHECK_LIB(ncurses, tigetstr, [ - AC_DEFINE(USE_TERMINFO) - LIBS="$LIBS -lncurses" -], [AC_CHECK_LIB(curses, tgetstr, [ - AC_DEFINE(USE_TERMCAP) - LIBS="$LIBS -lcurses" - AC_CHECK_HEADER(termcap.h, AC_DEFINE(HAVE_TERMCAP_H)) -])])]) - -dnl Some systems don't have term.h, some systems squirrel it away -dnl in an ncurses sub-directory of the system include directory. -dnl If term.h exists in the normal location, arrange for HAVE_TERM_H -dnl to be added to CFLAGS in the Makefile, by appending it to the -dnl DEFINES shell variable. Otherwise, if it exists under an ncurses -dnl sub-directory, arrange for HAVE_NCURSES_TERM_H to be set instead. -dnl If it isn't found in either of these places, neither of these -dnl variables is set, so term.h just doesn't get included. - -AC_CHECK_HEADER(term.h, AC_DEFINE(HAVE_TERM_H), [ - AC_CHECK_HEADER(ncurses/term.h, AC_DEFINE(HAVE_NCURSES_TERM_H)) -]) - -dnl Do the same search for curses.h. - -AC_CHECK_HEADER(curses.h, AC_DEFINE(HAVE_CURSES_H), [ - AC_CHECK_HEADER(ncurses/curses.h, AC_DEFINE(HAVE_NCURSES_CURSES_H)) -]) - -dnl The following variable lists the targets that will be created if -dnl the user runs make without any arguments. Initially we assume -dnl that we can create both the normal and the reentrant versions -dnl of the library. - -AC_SUBST(TARGETS) -TARGETS="normal reentrant" - -dnl Check for reentrant functions by attempting to compile and link a -dnl temporary program which calls them, being sure to include the -dnl appropriate headers and define _POSIX_C_SOURCE, just in case any -dnl of the functions are defined as macros. In the following, -dnl AC_CACHE_CHECK outputs the message "checking for reentrant -dnl functions". If this check has been done before, it assigns the -dnl cached yes/no value to tecla_cv_reentrant. Otherwise it uses -dnl AC_TRY_LINK() to attempt to compile and link the specified dummy -dnl program, and sets tecla_cv_reentrant to yes or no, depending on -dnl whether this succeeds. Finally it caches the value of -dnl tecla_cv_reentrant in the file config.cache, and writes "yes" or -dnl "no" to the terminal. - -AC_CACHE_CHECK(for reentrant functions, tecla_cv_reentrant, [ - KEPT_CFLAGS="$CFLAGS" - CFLAGS="$CFLAGS -D_POSIX_C_SOURCE=199506L" - AC_TRY_LINK([ -#include <unistd.h> -#include <sys/types.h> -#include <sys/stat.h> -#include <dirent.h> -#include <pwd.h> - ], [ - (void) readdir_r(NULL, NULL, NULL); - (void) getpwuid_r(geteuid(), NULL, NULL, 0, NULL); - (void) getpwnam_r(NULL, NULL, NULL, 0, NULL); - ], tecla_cv_reentrant=yes, tecla_cv_reentrant=no) - CFLAGS="$KEPT_CFLAGS" -]) - -dnl If the necessary reentrant functions weren't found to be -dnl available, default to only compiling the non-reentrant version of -dnl the library. - -if test $tecla_cv_reentrant = no; then - TARGETS="normal" -fi - -dnl Check for the select system call with the normal arguments, -dnl by attempting to compile and link a temporary program which -dnl calls it, being sure to include the appropriate headers. -dnl In the following, AC_CACHE_CHECK outputs the message -dnl "checking for select system call". If this check has been done -dnl before, it assigns the cached yes/no value to tecla_cv_select. -dnl Otherwise it uses AC_TRY_LINK() to attempt to compile and link -dnl the specified dummy program, and sets tecla_cv_select to yes -dnl or no, depending on whether this succeeds.

This is system dependent and is ignored if -dnl LINK_SHARED remains an empty string. On most platforms that -dnl support shared libaries, this will be .so.$MAJOR_VER, where -dnl MAJOR_VER is the major version number described above, which on -dnl some systems, tells the run-time loader if the program being -dnl loaded is binary compatible with a given version of the library -dnl (see the discussion of MAJOR_VER near the top of this file). -dnl The following empty default can be overriden on a system by system -dnl basis later in this file. - -AC_SUBST(SHARED_EXT) -SHARED_EXT="" - -dnl When a shared library is installed with the extension $SHARED_EXT, -dnl you can optionally produce other copies of this library with -dnl different extensions. This is done using symbolic or hard links, -dnl depending on what is available on the current filesystem, and the -dnl extensions to use for these links are listed in the following -dnl variable, separated by spaces. The following empty default can be -dnl overriden on a system by system basis later in this file. - -AC_SUBST(SHARED_ALT) -SHARED_ALT="" - -dnl The following variable lists extra compilation flags needed to -dnl create object files that can be included in shared libraries. -dnl Normally one would include a flag to tell the C compiler to -dnl compile position-independent code. This option commonly includes -dnl the acronym 'pic'. - -AC_SUBST(SHARED_CFLAGS) -SHARED_CFLAGS="" - -dnl On systems that support shared libraries, the following variable -dnl provides the command needed to make a shared library. In this -dnl variable, $$@ will be replaced with the name of the shared -dnl library, $$(LIB_OBJECTS) will be replaced with a space separated -dnl list of the object files that are to be included in the library, -dnl and libtecla$$(SUFFIX) will be the name of the library being -dnl built, minus the system-specific extension (eg. libtecla or -dnl libtecla_r). If LINK_SHARED is left as an empty string, shared -dnl library creation will not attempted. If your system supports -dnl shared library creation, you should override the default value of -dnl this variable in the target-specific case statement later in this -dnl file. - -AC_SUBST(LINK_SHARED) -LINK_SHARED="" - -dnl The following bourne shell case statement is where system -dnl dependencies can be added. In particular, if your system supports -dnl shared library creation, the following switch is the place to -dnl configure it. To do so you will first need to find out what target -dnl type was just assigned by the AC_CANONICAL_SYSTEM macro executed -dnl previously. The target type of your current system can be -dnl determined by cd'ing to the top level directory of the tecla -dnl distribution, and typing the command "sh config.guess". This will -dnl report what autoconf thinks the system type is. Note that this -dnl will be very specific, so if you know that the configuration -dnl parameters that you are about to provide apply to different -dnl versions of the current system type, you can express this in the -dnl case statement by using a wild-card in place of the version -dnl number, or by using an | alternation to list one or more version -dnl names. Beware that autoconf uses [] as quote characters, so if you -dnl want to use a regexp character range like [a-z], you should write -dnl this as [[a-z]]. - -case $target in -*solaris*) - AC_DEFINE(__EXTENSIONS__) - SHARED_EXT=".so.${MAJOR_VER}" - SHARED_ALT=".so" - LINK_SHARED='ld -G -M $$(srcdir)/libtecla.map -o $$@ -h $$(@F) -z defs -i $$(LIB_OBJECTS) $$(LIBS) -lc' - SHARED_CFLAGS="-Kpic" - case $CC in - */cc|cc) SHARED_CFLAGS="$SHARED_CFLAGS -xstrconst" ;; - gcc) CFLAGS="-I/usr/include $CFLAGS" ;; - esac - case $target in - *sparc*) SHARED_CFLAGS="$SHARED_CFLAGS -xregs=no%appl" - esac - ;; -*linux*) - SHARED_EXT=".so.${MAJOR_VER}.${MINOR_VER}.${MICRO_VER}" - SHARED_ALT=".so .so.${MAJOR_VER}" - -dnl See if the installed version of Gnu ld accepts version scripts. - - AC_CACHE_CHECK([for --version-script in GNU ld], tecla_cv_gnu_ld_script, [ - if (echo 'void dummy(void) {return;}' > dummy.c; $CC -c -fpic dummy.c; \ - ld -o dummy.so dummy.o -shared --version-script=$srcdir/libtecla.map) 1>&2 2>/dev/null; then - tecla_cv_gnu_ld_script=yes - else - tecla_cv_gnu_ld_script=no - fi - rm -f dummy.c dummy.o dummy.so - ]) - if test $tecla_cv_gnu_ld_script = yes; then - VERSION_OPT='--version-script=$$(srcdir)/libtecla.map' - else - VERSION_OPT='' - fi - - LINK_SHARED='ld -o $$@ -soname libtecla$$(SUFFIX).so.'${MAJOR_VER}' -shared '$VERSION_OPT' $$(LIB_OBJECTS) $$(LIBS) -lc' - SHARED_CFLAGS="-fpic" - ;; -*hpux*) - SHARED_EXT=".${MAJOR_VER}" - SHARED_ALT=".sl" - LINK_SHARED='ld -b +h $$(@F) +k +vshlibunsats -o $$@ -c libtecla.map.opt $$(LIB_OBJECTS) $$(LIBS) -lc' - SHARED_CFLAGS="+z" - ;; -*dec-osf*) - AC_DEFINE(_OSF_SOURCE) - ;; -esac - -dnl The following statement checks to see if the GNU C compiler has -dnl been chosen instead of the normal compiler of the host operating -dnl system.
