[ft-devel] using pkg-config
Folks, FreeType's configure script currently uses the `AC_CHECK_LIB' m4 macro to detect the presence of libz and libbz2. For libpng, it uses the `libpng-config' script. I will soon need the HarfBuzz library which doesn't provide a `harfbuzz-config' script. Does it make sense to completely switch to pkg-config? All of the above libraries provide .pc files. However, I wonder whether there are situations where there usage of pkg-config is problematic. A certain burden is that pkg-config itself must be installed (or pkgconf, which does the same in a probably better way). Is this a hassle on some platforms? If possible, I would like to avoid a hybrid approach (this is, first checking for `foo.pc', then trying `foo-config', then using `AC_CHECK_LIB[foo]'). Any advice is highly welcomed.

Re: [ft-devel] using pkg-config
Excuse me, just a small off-topic question, `libpng-config' script. I will soon need the HarfBuzz library which doesn't provide a `harfbuzz-config' script. Future release of FreeType2 will depend on HarfBuzz?

A certain burden is that pkg-config itself must be installed (or pkgconf, which does the same in a probably better way). Is this a hassle on some platforms? My impression is that although on mainstream linux distros it's a pretty good bet pkg-config is available, it's far from universal if you care about the fringes -- and freetype looks very much like the sort of library that tends to care more about the fringes than usual. It also used to the case that pkg-config didn't handle cross-compilation properly (I haven't checked this in a while), which seems like it would be an issue for freetype. It's not very hard to try both in turn, e.g.: have_libfoo=no PKG_CHECK_MODULES([luafoo], [luafoo], [have_luafoo=yes], [:]) if test $have_libfoo = no; then AC_CHECK_LIB([foo], [somefun], [have_luafoo=yes]) fi if test $have_libfoo = yes; then ...do stuff for libfoo... fi Should fallback gracefully to traditional checking if pkg-config isn't installed.. [When libraries are installed in funny places it can be a little more annoying without pkg-config, but AFAIK, libpng usually isn't one of those libraries...] -miles -- Innards, n. pl.

`libpng-config' script. I will soon need the HarfBuzz library which doesn't provide a `harfbuzz-config' script. Future release of FreeType2 will depend on HarfBuzz? Optionally only, as with the other libraries. Werner ___ Freetype-devel mailing list Freetype-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/freetype-devel
