There should be three variants: pkg-config, OS-based userspace policy (/usr/include vs. /usr/local/include) and user-defined one. > Here is a new proposal about this: > - use a PostConfigureCommand to invoke a shell script freetype2.sh > - in freetype2.sh invoke freetype-config and output flags in setup.data > using "echo 'freetype2_cflags = "$output"' >> setup.data' and > "echo 'freetype2_libs = "$output"' >> setup.data' > - add in _tags a "src/toto.cma: pkg_config_freetype2" > - add in myocamlbuild.ml a "tag [pkg_config_freetyp2; compile; ocaml] & > [...

But it is the best solution now and partially works for me. And please make the functions that loads setup.data and var_get data from it to be public. Right now I attempt to play with your code in myocamlbuild.ml and re-use it in my piece at bottom of the file. I'm always ready to test/use oasis from darcs when you put there something new. ermine > > Regards, > Sylvain Le Gall > > _______________________________________________ > Caml-list mailing list.
