The recent graphics/png 1.6.31 update added a line Requires: zlib
to libpng.pc. This makes sense as libpng requires libz. Consequently, the pkg-config output changes: pkg-config --cflags libpng old: -I/usr/local/include/libpng16 new: -I/usr/local/include/libpng16 -I/usr/include pkg-config --libs libpng old: -L/usr/local/lib -lpng new: -L/usr/local/lib -L/usr/lib -lpng -lz Should be fine, right? Well, it causes some interesting fallout. * games/chromium-bsu breaks because its configure script picks up libc.so.*.a as a library and tries to link with it. * games/pingus adds an additional -isystem/usr/include to the compiler line and now <cstddef> can't include <stddef.h>. * There's also strange x11/qt5/qtbase breakage, which may be related to this. I'm uncertain how to proceed. Should I simply revert the change to libpng.pc? The explicit addition of -lz is only required for static linking, but that is already covered by Libs.private in libpng.pc. -- Christian "naddy" Weisgerber na...@mips.inka.de
