Hi!
I'm trying to emerge freecad and one of the dependencies is mesa (with the opencl use flag enabled) but that installation fails:
| Code: | $ sudo emerge freecad -av
These are the packages that would be merged, in order:
Calculating dependencies... done!

Any ideas what could be wrong? How do I use LLVM for the installation of mesa? Please let me know if you need any more information than what can be seen above (USE flags etc.). The full output from emerge can be found here.
Thanks in advance!

| The first thing to try would be enabling that llvm USE flag. |

Haha! That was a pretty obvious thing to do and you know what? It worked. 
I didn't expect it to be portage related since it was an error during the configuration and portage had just told me to enable opencl:
| Code: | The following USE changes are necessary to proceed:
(see "package.use" in the portage(5) man page for more details)
# required by virtual/opencl-0-r4
# required by dev-python/pyopencl-2014.1
# required by pyopencl (argument)
>=media-libs/mesa-10.2.6 opencl |
I'll file a bug report to add llvm to the required use flags for mesa in virtual/opencl.
Thanks for your help! |
