pkgconfig file is rather messed up
neheb opened this issue · 3 comments
Normal pkgconfig files have the following format:
prefix=/usr
exec_prefix=/usr
libdir=${exec_prefix}/lib
includedir=${prefix}/include
This one is lacking the prefix variable which interferes with OpenWrt (we need to override the prefix).
I can probably make a PR to fix this later when I'm at my computer, but just to note how I think it would be fixed, prefix and exec_prefix variables would be added to the .pc, and substitutions for each would be added to the sed used to generate the file. Then a check would be done to see if the LIBDIR/INCLUDEDIR start with PREFIX, and if they do, strip the leading prefix and prepend \${prefix} or exec_prefix accordingly, then use whatever shell variables were set to this in place of the make variables in the build rule.
My basic solution https://github.com/openwrt/packages/blob/b443dda1f330a6b947d5dd287c4115a63713ba67/libs/libudev-zero/patches/010-pkgconfig.patch
Works well enough.
It won't work if someone sets LIBDIR or INCLUDEDIR to a path not starting with PREFIX.
