Created attachment 383590 [details] Updated ebuild Hi! I'm currently installing freecad and ran into the following problem. At first I didn't have the opencl USE flag enabled: 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 Enabling this useflag did, however, give me the following error when emerging mesa: ... checking for XF86VIDMODE... yes checking for DRIGL... yes checking for EXPAT... yes checking for NOUVEAU... yes checking for mincore... yes ./configure: line 21697: test: too many arguments checking for XCB_DRI2... yes configure: error: cannot enable OpenCL without LLVM Enabling the llvm USE flag solves this. To me it looks like llvm is required to build mesa with opencl support. My suggestion is to add llvm to one of the required USE flags for mesa in virtual/opencl just as opencl is today. I've attached an updated version of the current ebuild. Is there anything I've missed that could cause any problems?
This should be added to REQUIRED_USE as building fails if +opencl -llvm is set.
