<h1>
ac_config_pkgconfig_in
</h1>
<h2>
Obsolete Macro
</h2>
<p class="indent">
Deprecated with the advent of pkg-config.
</p>
<h2>
Synopsis
</h2>
<p class="indent" style="white-space:nowrap;">
<code>AC_CONFIG_PKGCONFIG_IN [(LIBRARY [, DESCRIPTION [,
DESTINATION]])]</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
Creates a custom pkg-config script. The script supports --cflags, --libs
and --version options.
</p>
<p>
This macro saves you all the typing for a pkg-config.in script; you don't
even need to distribute one along. Place this macro in your configure.ac,
et voila, you got one that you want to install.
</p>
<p>
The options:
</p>
<pre>
$1 = LIBRARY e.g. gtk, ncurses
$2 = DESCRIPTION one line description of library
$3 = DESTINATION directory path, e.g. src/scripts
</pre>
<p>
It is suggested that the following CFLAGS and LIBS variables are used in
your configure.ac. library_libs is *essential*. library_cflags is
important, but not always needed. If they do not exist, defaults will be
taken from LIBRARY_CFLAGS, LIBRARY_LIBS (should be -llibrary *only*) and
LIBRARY_LIBDEPS (-l options for libraries your library depends upon.
LIBLIBRARY_LIBS is simply $LIBRARY_LIBS $LIBRARY_LIBDEPS. NB. LIBRARY and
library are the name of your library, in upper and lower case repectively
e.g. GTK, gtk.
</p>
<pre>
LIBRARY_CFLAGS: cflags for compiling libraries and example progs
LIBRARY_LIBS: libraries for linking programs
LIBRARY_LIBDEPS*: libraries for linking libraries against (needed
to link -static
LIBRARY_REQUIRES: packages required by your library
LIBRARY_CONFLICTS: packages to conflict with your library
library_cflags*: cflags to store in library-config
library_libs*: libs to store in library-config
LIBLIBRARY_LIBS: libs to link programs IN THIS PACKAGE ONLY against
LIBRARY_VERSION*: the version of your library (x.y.z recommended)
*=required if you want sensible output, otherwise they will be
*guessed* (DWIM, but usually correct)
</pre>
<p>
There is also an AC_SUBST(LIBRARY_PKGCONFIG) that will be set to the name
of the file that we output in this macro. Use as:
</p>
<pre>
install-data-local: install-pkgconfig
install-pkgconfig:
$(mkinstalldirs) $(DESTDIR)$(bindir)
$(INSTALL_DATA) @LIBRARY_PKGCONFIG@ $(DESTDIR)$(prefix)/lib/pkgconfig
</pre>
<p>
Or, if using automake:
</p>
<pre>
pkgconfigdatadir = $(prefix)/lib/pkgconfig
pkgconfigdata_DATA = gimpprint.pc = @LIBRARY_PKGCONFIG@
</pre>
<p>
Example usage:
</p>
<pre>
GIMPPPRINT_LIBS="-lgimpprint"
AC_CHECK_LIB(m,pow,
GIMPPRINT_DEPLIBS="${GIMPPRINT_DEPLIBS} -lm")
AC_CONFIG_PKGCONFIG_IN([gimpprint], [GIMP Print Top Quality Printer Drivers], [src/main])
</pre>
