Missing dependency to dev-cpp/tbb #9

Closed gerion0 closed 4 years ago

gerion0 commented 4 years ago

Apearently Blender depends on TBB (in the default configuration) and fails with a completely dubious error message, when TBB is not present:

...

CMake Error at source/creator/CMakeLists.txt:78 (blender_include_dirs):

...

Following this error, it searches for TBB in the build files, given that the WITH_TBB option is set. From the main CMakeLists file, this is said for WITH_TBB:

option(WITH_TBB   "Enable features depending on TBB (OpenVDB, OpenImageDenoise, sculpt multithreading)" ON)

Installing dev-cpp/tbb solves the configure error. So I think that the ebuild should either hard depend on tbb and setting the WITH_TBB option explicitly or toggle WITH_TBB dependend on a use flag and let depend openvdb etc. also on it.

This error happens in 2.82 and 2.82a for me.

Thanks, I have added tbb as new USE flag. It is required for openvdb, oidn, elbeem (and usd once I get it working). If those flags are not used, then blender compiles for me with tbb disabled. I have enabled tbb by default as elbeem is in the default set.
