Re: [Bf-committers] Change of MinGW64 compiler
There have been a few issues with the new MinGW compiler unfortunately, one is crashes with missing or packed images (which only happens on scons) and we have another bug possibly deadlock-related in the tracker. Unfortunately with me being in GSOC and the insane amount of time it takes to compile blender in MinGW, especially with scons, I probably won't be able to see to these bugs soon :/. If we can't resolve these issues we will probably have to revert to the previous compiler. It might have not supported openmp but at least it worked as expeceted elsewhere. Still, I hope to resolve the above issues. ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers

This build is the new one used by the buildbot. What issue are you having exactly?

Re: [Bf-committers] Change of MinGW64 compiler
Hi, the current build bot mingw win64 r48748 crashes on startup. Confirmed by JesterKing on IRC. jesterKing: 48700 already crashes on startup. I'm guessing it has to do with the dlls that are now used in mingw64 builds (gomp, gcc_s_sjlj, winpthread, stdc++-6) Could this be a problem with your latest changes? Who could fix this? Blender Developers (maybe you) or is it a problem on the mingw side?

Re: [Bf-committers] Change of MinGW64 compiler
Some debugging reveals that the crash is caused by the pthreadGC2-w64.dll library that is included with the buildbot builds. I have no idea how this library made its way into the build, it is not needed for building, nor part of MinGW-w64 or the Blender mingw64 library repository. This is definitely an issue with the buildbot, not the compiler or Blender code base. On 9/07/2012 7:54 PM, Constantin Rahn wrote: Hi, the current build bot mingw win64 r48748 crashes on startup.

Re: [Bf-committers] Change of MinGW64 compiler
This is an issue with the buildbot, it will need to be updated with the new compiler. About the issue with the crash, it is related to image paths that are not found. I did some research during the weekend without success. cmake builds do -not- have this problem so I suspect it may be a lib order issue/missing define or something similar. I will try to find some way to fix this (probably through a lot of trial and error/recompiling libraries etc) but given that I am in the middle of gsoc right now it may take a while :/ . ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers

From correspondence on MinGW-w64 mailing list it looks like it is related to the specific MinGW-w64 build we are using. I have recently built with openmp enabled with another MinGW-w64 package and it looks like it works fine. There are a few things to take care of, mainly recompile openexr to resolve some thread issues but everything else seems to be OK, though other issues may creep up of course. Are there any objections to this? I am aware we may have to update the builder too but I will test whether a recompiled openexr works with the current compiler without issues. ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers
