Re: [osg-users] Recurse on a private mutex (FreeBSD)
This had me fooled. The call stack seemed to indicate an Nvidia OpenGL bug But it wasn't. #2 0x28913b78 in abort () from /lib/libc.so.6 #3 0x2895bc6f in pthread_testcancel () from /lib/libpthread.so.2 #7 0x28a0314d in _nv07gl () from /usr/local/lib/libGL.so.1 #8 0x28a725e4 in ?? () from /usr/local/lib/libGL.so.1 #19 0x28fd1937 in _nv000486gl () from /usr/local/lib/libGLcore.so.1 FreeBSD has different thread libs. Mixing them was the real cause. Solution was to add pthread to TARGET_LINK_LIBRARIES in CMakeLists.txt (of my app). ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Recurse on a private mutex (FreeBSD)
Hi Jim, Unfortunately the stack trace doesn't tell us much beyond its something related to pthreads, it could be a bug in pthreads itself, a bug in OpenThreads, or a bug in OSG but we so far have absolutely no way of telling. You'll need to try and isolate the failure condition from the top level - by starting off with basic examples that do very little to see if they crash then build up to examples that are known to crash. The most stripped down example will be osgversion, then osgconv, then moving up to osgviewer. Could you try these are report back what happens. BTW, your the first person to report this problem, so either there is something particular about your system or the way you are using it, or no one else has yet compiled 2.x under FreeBSD. Perhaps if others are working under FreeBSD then can come forward with there experiences to see if there is any pattern to this problem. Robert.
