The resulting <TT>`configure'</TT> script performs various checks for installed programs, compiler characteristics and other system information such as available headers and libraries. See Info file `autoconf', node `Top', for more information. </P> <P> GIMP-Print provides an @command{m4} macro, <CODE>AM_PATH_GIMPPRINT</CODE>, suitable for use in a <TT>`configure.in'</TT>. It defines the environment variables @env{GIMPPRINT_CFLAGS}, @env{GIMPPRINT_LIBS} and @env{GIMPPRINT_CONFIG}. You can optionally specify a minimum version of the library to use, and shell script to run if the test suceeds or fails. </P> <P> <DL> <DT><U>Macro:</U> <B>AM_PATH_GIMPPRINT</B> <I>([<VAR>minimum-version</VAR> [, <VAR>action-if-found</VAR> [, <VAR>action-if-not-found</VAR>]]])</I> <DD><A NAME="IDX11"></A> Check for an installed version of GIMP-Print greater than or equal to <VAR>minimum-version</VAR>. </P> <P> <VAR>action-if-found</VAR> is a list of shell commands to run if the check for the library succeeds; <VAR>action-if-not-found</VAR> is a list of shell commands to run if the check fails. </P> <P> The macro sets the following environment variables: @env{GIMPPRINT_CFLAGS}, @env{GIMPPRINT_LIBS} and @env{GIMPPRINT_CONFIG}. It also will substitute them into any <TT>`Makefile.in'</TT> you specify in <CODE>AC_OUTPUT</CODE> because it calls <CODE>AC_SUBST</CODE> for each of them. However, you will probably be using @command{automake} to generate your <TT>`Makefile.in'</TT> files (see section <A HREF="gimpprint_9.html#SEC14">3.4 @command{automake}</A>). </P> </DL> <P><HR><P> Go to the <A HREF="gimpprint_1.html">first</A>, <A HREF="gimpprint_7.html">previous</A>, <A HREF="gimpprint_9.html">next</A>, <A HREF="gimpprint_47.html">last</A> section, <A HREF="gimpprint_toc.html">table of contents</A>. </BODY> </HTML>
