The _OPENTHREADS_ATOMIC_USE_GCC_BUILTINS reports success on the Ubuntu machine. > Can you make sure you're linking to OpenThreads (the right > version) and that you've included the right OpenThreads/Config header. > > Note that if the machine fails the atomic test, the > OpenThreads/Config header will be different than if it > passes.

But the OpenThreads/Config file is NOT under source control. I have built OSG with CMAKE "out of source" and if I check the OpenThreads/Config file on each computer I can clearly see that they are diffrent. The Windows machine is using: _OPENTHREAD_ATOMIC_USE_WIN32_INTERLOCKED The Ubuntu machine is using: _OPENTHREAD_ATOMIC_USE_GCC_BUILTINS And the OpenSuse machine is using: _OPENTHREAD_ATOMIC_USE_MUTEX I have also tried to use OSG 2.7.3, which results with the same linking errors. /Björn _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
