2016-08-29 Thread Francesc Juhe

I have no idea. I hard-coded libiomp5 because that’s the one included in darwin 
libs and the default used by the also included clang-omp-3.5.
Official clang 3.7 uses libgomp as default and 3.8 uses libomp.

iomp5 is hard-coded on several places, it’s just not hard-coded on the lines I 
had to modify because -fopenmp seems to assume libiomp5 in clang-omp-3.5 so 
it’s not needed:

CMakeLists.txt  1428set(CMAKE_REQUIRED_FLAGS "-L${LIBDIR}/openmp/lib 
-liomp5") # these are only used for the checks
build_files/cmake/platform/platform_apple.cmake 390 
${LIBDIR}/openmp/lib/libiomp5.dylib
build_files/cmake/platform/platform_apple.cmake 391

Hi,

Is it possible to somehow automatically detect which OpenMP library to use
without need to hard-code it per-compiler-version? Maybe using try_compile
CMake trickery?

Re: [Bf-committers] Buildbot cuda-hack

2016-08-28 Thread Francesc Juhe

I run a few tests regarding clang and omp after installing OSX 10.11 and Xcode 
7.3.1.

It seems that clang-omp-3.5 from libs can’t compile using OSX 10.11 SDK.

So, I downloaded clang 3.7.0 and 3.8.0 darwin binaries from official page and 
both compile blender ok after a minor modification on cmake.

seems to have fixed incompatible compiler issues but as I don’t know what the 
cuda-hack does, I am not sure.

Any comment on what the cuda-hack does/solves is very welcome.

Re: [Bf-committers] Buildbot cuda-hack

2016-08-26 Thread Francesc Juhe

But the cuda-hack commit was for CUDA 7.5 initially, I just ask about it now 
because I am creating a new build environment with el capitan and wanted to 
know more of what this “hack” did to better understand the build process and be 
prepared if I had the same issue.

About the openmp, I have been using clang 3.5 from blender libs  to get openmp 
support without finding any issues but since the change from scons to cmake on 
osx buildbot is no longer using it (scons buildbot config pointed to that clang 
from blender libs but cmake doesn't) and so it is missing openmp support but as 
the release build has openmp I wanted to know if release builders were using 
this clang from blender libs or a different one. In my build I added an osx 
config file to point to clang 3.5 and I think it could be better if official 
buildbot had openmp back like before when it used scons so that buildbot builds 
are more similar to releases, otherwise there could be issues not present on 
buildbot but affecting release. Don’t know, just my opinion.

Also, there is another thing missing since scons was removed in favor of cmake, 
osx buildbot does not include the blenderplayer binary inside 
blenderplayer.app, I fix it in my build with this diff:

diff --git a/source/blenderplayer/CMakeLists.txt 
b/source/blenderplayer/CMakeLists.txt

I'd say cuda8 is pointless for you right now, cause pascal gpu is not 
yet supported by the NV/OSX (Quadro-) drivers.

You would definitely loose openmp capability unless you compile and use 
a vanilla clang 3.7 which supports it.

[Bf-committers] Buildbot cuda-hack

2016-08-26 Thread Francesc Juhe

Hi,

Some time ago noticed this commit 
https://developer.blender.org/rB3a24e6320f31a790ea9d3c912a35db2186140b71 
changing the nvcc compiler on builbot but I did not give it much though as I 
was having no issues compiling with cuda 7.5 and clang 3.5 from libs folder on 
OSX 10.9. But now with CUDA 8 it seems I have to update to OSX 10.11 and Xcode 
7.3.

So, how does this cuda-hack work?
Also, OSX buildbot builds seem to be compiled without OpenMP but release builds 
are compiled with it. What are the appropriate steps for building a release 
build?

Thank you,
Francesc
