- Fix runtime error with uClibc
- Patch inspired by
- https://www.winehq.org/pipermail/wine-bugs/2011-September/288987.html
- http://git.alpinelinux.org/cgit/aports/tree/main/wine/uclibc-fmaxf-fminf.patch?id=c9b491b6099eec02a835ffd05539b5c783c6c43a
- Starting an app using mesa3d 10.5.x, Kodi for example, fails:
- /usr/lib/kodi/kodi.bin: symbol 'fminf': can't resolve symbol in lib '/usr/lib/dri/i965_dri.so'.
- libGL error: unable to load driver: i965_dri.so
- libGL error: driver pointer missing
- libGL error: failed to load driver: i965
- libGL error: unable to load driver: swrast_dri.so
- libGL error: failed to load driver: swrast
- This patch was rejected by upstream mesa3d:
- http://lists.freedesktop.org/archives/mesa-dev/2015-March/079436.html
- The real fix was committed to uClibc:
- http://git.uclibc.org/uClibc/commit/?id=6c4538905e65ceb203f59aaa9a61728e81c6bc0a
- Until the external toolchains do not contain this uClibc patch we keep this
