Our version of clang fails with latest SDK. It's not really clear if such
change will disable openmp or not (-fopenmp doesn't throw an error, but
it might be a silent fail).
In any case, builds without OpenMP is better than no builds at all.\
This is more an experiment, not guaranteed to work but at the same time
building of kernels seems to work manually in the same chroot. Perhaps
latest changes helped compiler to optimize registers usage.
This commit makes sure Linux and Windows buildbots are using OpenSubdiv
and also enables OpenSubdiv by default on Windows.
OSX is kept disabled still, this is due to OpenGL restrictions which are
not solved in any way yet.
Linux is defaults to OpenSubdiv disabled because it needs precompiled
library.
The documentation could be found there:
http://wiki.blender.org/index.php/User:Nazg-gul/OpenSubdiv
Recent changes to kernel broke compilation of the kernels again, need some
other kind of solution for this issue.
Don't have much time for this currently, but will be addressed before the
release.
Meanwhile it's better to have some buildbot builds instead of totally failing
one.
Did this in packaging buildbot rule because of several reasons:
- CMake doesn't deliver name of package which we expect it to be for buildbot
- CMake doesn't really know that building happens for buildbot
- Making default CPAck name matching buildbot's naming is kinda stupid
Probably we can pass CPack name via command line arguments, but i'm happy with
the current state and one might change things in the future.
Doesn't mean we're 100% ready for the transition, but need to start somewhere
anyway. Changes:
- OSL is no longer supporting cpp and requires usage of Boost Wave.
So now Wave component of Boost is optionally demanded when looking for the
Boost libraries if OSL is enabled.
Only did this for Linux, MSVC seems already using Wave. Not sure about OSX.
- Because of the same reason OSL should be moved prior Boost for linker.
- Whole archive trick makes it so linking fails with duplicated symbols, so
removed it for the new OSL. Didn't see issues with this so far.
- Added some code to check OSL version on Linux. Would need to move all that
to FindOpenShadingLanguage.cmake which we can get from Cycles standalone
repository.
So in theory no affect on current stup would be made at all.
- Added some tweaks to buildbot files. It now seems to be happy with the new
OSL libraries, but again, those tweaks are not in action yet.
All this was tested on Linux only. Win/OSX might still need some tweaks to
support new OSL.
P.S. This doesn't mean we're pushing OSL update yet, just making some
preliminary tweaks to avoid entropy of PITA when we'll actually want to
switch.
New scons discontinued support of python2.6, so we needed
to build just another python in the release and buildbot
environment.
Hope latest scons upgrade a least bring new msvs support
and not only lead to just-another-frustration.
There might be some more upcoming commits, because you
never can be sure there's no typos in the buidbot script
for until you actually fire the builder up.
- due OSL i386 never worked on OSX, the new libs do not even contain this arch !
- As we had to fix duplicated symbols from generic UTF finctions same in LLVM and COLLADA,
LLVM-less build must have UTF lib reenabled
