AX_CREATE_PKGCONFIG_INFO [(outputfile, [requires [,libs [,summary [,cflags [, ldflags]]]]])]
$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 = $PACKAGE_CFLAGS (as set at the point in configure.ac) $6 = $PACKAGE_LDFLAGS (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 consequence, most of the generatable installable stuff can be made from information being updated in a single place for the whole project.
