Hello Björn,
I am building OpenSceneGraph 2.6.0 from source on a machine running SUSE 10.2.
When running cmake script I get the following warnings.
...
-- Performing Test _OPENTHREADS_ATOMIC_USE_GCC_BUILTINS
-- Performing Test _OPENTHREADS_ATOMIC_USE_GCC_BUILTINS - Failed
-- Performing Test _OPENTHREADS_ATOMIC_USE_MIPOSPRO_BUILTINS

...
What version of gcc do you have? I think
_OPENTHREADS_ATOMIC_USE_GCC_BUILTINS should succeed with any modern gcc
version, but Matthias will be able to tell you more - he wrote the
atomic support.
Compiling and linking OSG works ok. But if I try compile and link my
application I get the following link errors:
display.o: In function 'osg::Referenced::ref() const':
/home/work/sim/../../dependencies/include/osg/Referenced:148: undefined
reference to 'OpenThreads::Atomic::operator++()'
display.o: In function 'osg::Referenced::unref() const':
/home/work/sim/../../dependencies/include/osg/Referenced:165: undefined
reference to 'OpenThreads::Atomic::operator--()'
Anyone have any ideas how to solve this?
You need to link to OpenThreads now, which was not required before the
Atomic ref counting was integrated into OSG. That will resolve those
linker errors.
Hope this helps,
J-S
