I had some problem with an app behaving badly and reporting: libpng warning: Application was compiled with png.h from libpng-1.5.6 libpng warning: Application is running with png.c from libpng-1.2.44 gd-png: fatal libpng error: Incompatible libpng version in application and library I turns out the gd was linked to the system png (1.2) rather than the png from the prefix: otool -L /Users/frb15/Desktop/Gentoo/usr/lib/libgd.2.dylib /Users/frb15/Desktop/Gentoo/usr/lib/libgd.2.dylib: /Users/frb15/Desktop/Gentoo/usr/lib/libgd.2.dylib (compatibility version 3.0.0, current version 3.0.0) /Users/frb15/Desktop/Gentoo/lib/libiconv.2.dylib (compatibility version 8.0.0, current version 8.0.0) /Users/frb15/Desktop/Gentoo/usr/lib/libjpeg.8.dylib (compatibility version 12.0.0, current version 12.0.0) /usr/X11/lib/libpng12.0.dylib (compatibility version 45.0.0, current version 45.0.0) /Users/frb15/Desktop/Gentoo/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.1.7) I am investigating.
I see the ebuild is hardwired to png14 which of course broke when switching to 1.5. I suggest the following be inserted in the ebuild: sed -i \ -e "s:png12:$(libpng-config --libs | cut -dl -f2):" \ configure.ac || die instead of the current: sed -i \ -e 's:png12:png14:' \ configure.ac || die It works properly here.
I believe this bug was fixed in gentoo-x86 by the following commit by vapier: 15 Dec 2011; Mike Frysinger <vapier@gentoo.org> gd-2.0.35-r3.ebuild, +files/gd-2.0.35-libpng-pkg-config.patch: Use libpng's pkg-config files rather than xxx-config scripts. So if prefix-overlay is shipping gd, it should propably sync from gentoo-x86 in order to resolve this bug. Or possibly the original reporter just needs to sync his tree.
synced now, that hopefully fixes this indeed
(In reply to comment #3) > synced now, that hopefully fixes this indeed no reply from the reporter during these months, so assuming fixed
