dnl This is the input file which autoconf uses to construct a
dnl "configure" script for the tecla library. 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="6"

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="3"

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.
dnl Note that we do not use AC_PROG_RANLIB because (at least in
dnl autoconf 2.53) this does not check for cross-compilation.

AC_CHECK_TOOL(RANLIB, ranlib)

dnl Set STRIP as appropriate, especially when cross-compiling

AC_CHECK_TOOL(STRIP, strip)

dnl Set LD as appropriate, especially when cross-compiling

AC_CHECK_TOOL(LD, ld)

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 When compiling the reentrant version of the library, the following
dnl compiler flags are presented to the compiler, in addition to those
dnl that are used when compiling the non-reentrant version of the
dnl library. The PREFER_REENTRANT macro is an internal libtecla macro
dnl whose presence reports when the reentrant version of the library
dnl is being compiled. This allows the code to determine when to
dnl disable features that can't portably be implemented reentrantly,
dnl such as username completion. The existence of the _POSIX_C_SOURCE
dnl macro can't be reliably used for this purpose, since some systems
dnl define it by default for all code.

AC_SUBST(DEFS_R)

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]].
