[Bf-committers] Migrating Blender builds to Visual Studio 2010
Ok, First test with a fresh VC 2010 Build of version 56113 from SVN. I could measure a speed up of 4.13% in cycles compared to a build (56113) with 2008 and the libs from trunk. It was a simple scene of a character with some SSS and HDRI. I guess that is not much, but it's not a real benchmark just a test. I would like to do more testing on this to see if the OpenMP performance for physics is better or not. Until now VC2010 seems to have little benefit. I still have some library porting to do. But the build issues for OSL and OIIO are fixed now thanks to Brecht and Igritz on GitHub.

Hi There, I'm curious to know - did you investigate why it crashes on startup?, could you link to a stack-trace of the crash? Blender should be quite portable between different compilers so its strange this fails on new msvc.

Re: [Bf-committers] Migrating Blender builds to Visual Studio 2010
Hi. I have basic VC 2012 build working (without Cycles and other fancy stuff). Didn't get time around. Try to disable all extensions with external dependencies like Collada, OpenExr, translations, and even python. After it, you should be able to compile and run minimal Blender. Then try to recompile all dependencies. And VS 2012 seems to require: if(MSVC11) add_definitions(/D_ALLOW_KEYWORD_MACROS /DMS_WINDOWS) endif() in main CMakeList.txt line 998 Best, Alex On 4/15/2013 8:55 AM, Campbell Barton wrote: Hi There, I'm curious to know - did you investigate why it crashes on startup?, could you link to a stack-trace of the crash?

Re: [Bf-committers] Migrating Blender builds to Visual Studio 2010
Hi Jürgen, first of all thanks for your work and the offer. I doubt that we can change to vc2010 so easily. If we would switch, we would need a couple of MSVC professional licences for the release builders, the build bot and core devs. Also, I rather not have yet another build system to support inside our cmake and scons files. We already have VC 2008 and MinGW. And I don't think 2010 gives us a lot (if any?) benefits over 2008 as well. And last but not least, if we do a migration, than I rather move to the latest one, rather than to 2010.

Maybe it is important to check the nvidia toolkit page: citation: Table 1. Supported Windows Compilers (32-bit and 64-bit) Compiler IDE Visual C++ 10.0 Visual Studio 2010 Visual C++ 9.0Visual Studio 2008 see: http://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html Maybe that is good to know ? cheers, Gaia On 15.04.2013 15:38, Thomas Dinges wrote: Hi Jürgen, first of all thanks for your work and the offer.

Re: [Bf-committers] Migrating Blender builds to Visual Studio 2010
Hi Jürgen, Do you know what are the benefits of using VC 2010? Is Blender faster? If there are no benefits for the end user, I don't see a reason to switch. Regarding CUDA, I really hope nVidia will release a new Toolkit soon, which brings some improvements and support for VC 2012, this would be great. Best regards, Thomas Am 15.04.2013 16:25, schrieb Jürgen Herrmann: Hi Thomas and Gaia, I tried the VS 2012 way before stepping down to 2010. Nvcc can be forced to work with VC 2012, but I don't consider this safe. VC 2012 express supports a good load of features previously only available in pro versions. Even OpenMP is in express now. But the compiler has several flaws. It crashes very often with normal optimization levels (O2 /Ob2). So I found porting to VC 2010 until MS brings patches for the compiler and nvidia brings VC 2012 support would make it a bit easier to take the step from 2010 to 2012 instead of 2008-2012 I would volunteer to take over support for the 2010 build system and do the porting to vs 2012 when applicable.

By the way Thomas, I get a strange error when trying to compile OSL from scratch. Multiple error C2874: using-declaration causes a multiple declaration of 'std::tr1::shared_ptr' I just don't get the problem here :-( It seems that boost memory.hpp causes this problem.

FWIW LuxRender saw a small but definite speedup (around 5-10% depending on scene) when switching to VC 2010. However the main reason to use VS 2010 would be the significantly improved IDE experience. It's night and day compared to VS 2008, IMHO. Just my 2 cents :) Cheers - Asbjørn ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers
