AX_CREATE_PKGCONFIG_INFO [(outputfile, [requires [,libs [,summary]]])]
0.5.55 : guidod
$1 = $PACKAGE_NAME.pc
$2 = (empty)
$3 = $PACKAGE_LIBS $LIBS (as set at that point in configure.ac)
$4 = $PACKAGE_SUMMARY (or $1 Library)
$5 = $CPPFLAGS $PACKAGE_CFLAGS (as set at the point in configure.ac)
PACKAGE_NAME defaults to $PACKAGE if not set.
PACKAGE_LIBS defaults to -l$PACKAGE_NAME if not set.
the resulting file is called $PACKAGE.pc.in / $PACKAGE.pc
You will find this macro most useful in conjunction with ax_spec_defaults that can read good initializers from the .spec file. In consequencd, most of the generatable installable stuff can be made from information being updated in a single place for the whole project.
