| 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 |
