There is a hardlink in the Mesa 10.5.1 sources that needs repaired / converted to a soft link:
$ ls -i src/gallium/state_trackers/egl/x11/dri2.c
$ ls -i src/glx/dri2.c
/Builds> tar xf mesa-10.5.1.tar.gz
tar: mesa-10.5.1/src/gallium/state_trackers/egl/x11/dri2.c: Cannot hard link to ‘mesa-10.5.1/src/glx/dri2.c’: Operation not supported
tar: Exiting with failure status due to previous errors
It looks as though this issue was introduced here:
Probably just want to backport the gallium/egl state tracker removal to 10.5.
Fear that we have links in src/mesa/drivers/dri/r200, which became hard ones with 10.5 as well. So porting that over will not really cut it.
I will check who exactly is causing this - tar or autotools, and will look into a proper way to handle it.
Upon closer look the r200 ones are dereferenced upon compression, so a second copy of the files is shipped.
Alexander, 10.5.2 should resolve this bug plus it adds the egl/haiku files, so that you guys actually have the source to actually build stuff :-)
