blender-2.68-eigen-checks.patch
Blender-2.68a itself is API-compatible with eigen-3.2.0. The problem is in braindead cmake checks for eigen: it checks all headers, even those not used by blender directly. This problem can be fixed by removing offending checks. Afterwards blender builds and works fine.
I can confirm this problem on ~amd64, eigen-3.1.4 from science overlay works fine.

Actually I'd suggest that current files/05-blender-2.68-unbundle-eigen3.patch should be modified - currently it fixes the paths to all individual include files to /usr/include (in intern/itasc/CMakeLists.txt) but it should actually simply remove these "source" lines. cmake is supposed to check included files itself. Best regards, Bernd science overlay looks unmaintained, it gives errors on cache generation and creates a lot of blockers for me, so don't expect me to test anything against that overlay however, the header checks are definitely useless + 29 Oct 2013; Julian Ospald <hasufell@gentoo.org> + files/05-blender-2.68-unbundle-eigen3.patch: + supposedly fix bug 482874 |
