ac_create_generic_config

Creates a generic PACKAGE-config file that has all the things that you want, hmm, well, atleast it has --cflags, --version, --libs. Ahhm, did you see ac_path_generic in the autoconf-archive? ;-)

this macros 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.

oh, btw, if the first arg looks like "mylib -lwhat' then it will go to be added to the --libs, and mylib is extracted.

the defaults: $1 = $PACKAGE $LIBS $2 = $VERSION there is also an AC_SUBST(GENERIC_CONFIG) that will be set to the name of the file that we did output in this macro. Use as:

 install-exec-local:    install-generic-config

 install-generic-config:
    $(mkinstalldirs) $(DESTDIR)$(bindir)
    $(INSTALL_SCRIPT) @GENERIC_CONFIG@ $(DESTDIR)$(bindir)
