Re^11: gmake error on Glib compile

I just had a go with the different pkg-config utilities. The difference appears to be that the MSYS2 version prepends the relevant path when run outside of the MSYS2 environment. I guess the pure-perl version could be taught to work with such paths but it's perhaps only an issue because these builds are using mingw64 files?

Windows cmd shell:

C:\path>set PKG_CONFIG_PATH=C:\msys64\mingw64\lib\pkgconfig

C:\path>pkg-config --libs glib-2.0
-L/mingw64/lib -lglib-2.0 -lintl

C:\path>\msys64\mingw64\bin\pkg-config.exe --libs glib-2.0
-LC:/msys64/mingw64/lib -lglib-2.0 -lintl

MSYS2 mingw64 shell:

$ pkg-config --libs glib-2.0
-lglib-2.0 -lintl

The difference appears to be that the MSYS2 version prepends the relevant path when run outside of the MSYS2 environment I found that if the "${prefix}" in the pc files is replaced with the actual (hard coded) directory, then Strawberry's pkg-config.bat worked fine. IOW, I think you're right - and I think it's because pkg-config.bat doesn't understand "${prefix}" like MSYS2 does. I had originally set CPATH and LIBRARY_PATH environment variables to point to the relevant headers and libs when building with pkg-config.bat. I think that worked because it then meant that pkg-config.bat did not have to locate those files. (They just automatically get found anyway.) Cheers, Rob	[reply]

I think it's because pkg-config.bat doesn't understand "${prefix}" like MSYS2 does. It's not so much that the pure perl pkg-config does not understand `${prefix}`. It's more that it does not correct for the MSYS2 paths. The mingw64 glib-2.0.pc file is below. The prefix is set to a location that only MSYS2 knows how to convert to a "normal" windows path. If the prefix is set to `prefix=${pcfiledir}/../..` then the issue might disappear. FWIW, this approach is used for all but one of the .pc files under strawberry perl 5.38 (that file being zlib.pc). `prefix=/mingw64 includedir=${prefix}/include libdir=${prefix}/lib bindir=${prefix}/bin glib_genmarshal=${bindir}/glib-genmarshal gobject_query=${bindir}/gobject-query glib_mkenums=${bindir}/glib-mkenums Name: GLib Description: C Utility Library Version: 2.76.4 Requires.private: libpcre2-8 >= 10.32 Libs: -L${libdir} -lglib-2.0 -lintl Libs.private: -lws2_32 -lole32 -lwinmm -lshlwapi -luuid -lm Cflags: -I${includedir}/glib-2.0 -I${libdir}/glib-2.0/include` [download]	[reply] [d/l] [select]
