CMake should be automatically detecting these features, the following
OpenSceneGraph/src/OpenThreads/pthreads/CMakeLists.txt portion should
be doing this:
CHECK_FUNCTION_EXISTS(pthread_yield HAVE_PTHREAD_YIELD)
..
CHECK_FUNCTION_EXISTS(pthread_getconcurrency HAVE_PTHREAD_GETCONCURRENCY)
..
CHECK_FUNCTION_EXISTS(pthread_setconcurrency HAVE_PTHREAD_SETCONCURRENCY)
..
CHECK_FUNCTION_EXISTS(pthread_setaffinity_np
HAVE_PTHREAD_SETAFFINITY_NP)
For these to pass then functions pthread_yield,
pthread_getconcurrency, pthread_setconcurrency and
pthread_setaffinity_np will need to be present in the system
pthreads.h header.
If you run make VERBOSE=1 you should see the -D entries assocated
with these cmake variables. What I see on my system when I do this
is:
Building CXX object
src/OpenThreads/pthreads/CMakeFiles/OpenThreads.dir/__/common/Atomic.o
cd /home/robert/OpenSceneGraph/src/OpenThreads/pthreads &&
/usr/bin/c++ -DHAVE_PTHREAD_CANCEL -DHAVE_PTHREAD_SETCANCELSTATE
-DHAVE_PTHREAD_TESTCANCEL -DHAVE_SCHED_YIELD

-o CMakeFiles/OpenThreads.dir/__/common/Atomic.o -c
/home/robert/OpenSceneGraph/src/OpenThreads/common/Atomic.cpp

What do you get if you do a build with VEROSE=1?
Robert.
