Configuring OpenCV with TBB for ARM (Ubuntu, 3.0.63)

I am trying to compile OpenCV libraries with TBB support for odroid U2 (with quad core ARM Cortex-A9 MPCore processor). I have no problem compiling the current OpenCV (from github) without TBB. And also I have no problems compiling TBB libs fron sources - tbb41_20130116oss_src.tgz , and I successfully created the TBB libraries:

root@odroid :~/src/tbb41_20130116oss/build/linux_armv7l_gcc_cc4.6_libc2.15_kernel3.0.63_release# ls arena.d concurrent_queue.o frontend.d libtbbmalloc.so.2 proxy.d scheduler.o task_v2.d tbb_thread.d arena.o concurrent_queue_v2.d frontend.o libtbbmalloc_proxy.so proxy.o semaphore.d task_v2.o tbb_thread.o backend.d concurrent_queue_v2.o governor.d libtbbmalloc_proxy.so.2 queuing_mutex.d semaphore.o tbb.def tbbmalloc.d backend.o concurrent_vector.d governor.o market.d queuing_mutex.o spin_mutex.d tbb_function_replacement.d tbbmalloc.def backref.d concurrent_vector.o itt_notify.d market.o queuing_rw_mutex.d spin_mutex.o tbb_function_replacement.o tbbmalloc.o backref.o concurrent_vector_v2.d itt_notify.o mutex.d queuing_rw_mutex.o spin_rw_mutex.d tbb_main.d tbbmallocproxy.def cache_aligned_allocator.d concurrent_vector_v2.o itt_notify_malloc.d mutex.o reader_writer_lock.d spin_rw_mutex.o tbb_main.o tbbvars.csh cache_aligned_allocator.o condition_variable.d itt_notify_malloc.o observer_proxy.d reader_writer_lock.o spin_rw_mutex_v2.d tbb_misc.d tbbvars.sh concurrent_hash_map.d condition_variable.o large_objects.d observer_proxy.o recursive_mutex.d spin_rw_mutex_v2.o tbb_misc.o version_string.ver concurrent_hash_map.o critical_section.d large_objects.o pipeline.d recursive_mutex.o task.d tbb_misc_ex.d concurrent_monitor.d critical_section.o libtbb.so pipeline.o rml_tbb.d task.o tbb_misc_ex.o concurrent_monitor.o dynamic_link.d libtbb.so.2 private_server.d rml_tbb.o task_group_context.d tbb_statistics.d concurrent_queue.d dynamic_link.o libtbbmalloc.so private_server.o scheduler.d task_group_context.o tbb_statistics.o root@odroid :~/src/tbb41_20130116oss/build/linux_armv7l_gcc_cc4.6_libc2.15_kernel3.0.63_release#

I can compile my own program using g ++ using these TBB libraries, but I cannot configure OpenCV to view these TBB libraries:

 root@odroid :~/src/work/opencv/release# cmake -D CMAKE_BUILD_TYPE=RELEASE -D WITH_TBB=ON -D CMAKE_INSTALL_PREFIX=/usr/local .. -- Detected version of GNU GCC: 46 (406) -- Found OpenEXR: /usr/lib/libIlmImf.so -- checking for module 'gstreamer-app-0.10' -- package 'gstreamer-app-0.10' not found -- Looking for linux/videodev.h -- Looking for linux/videodev.h - not found -- Looking for linux/videodev2.h -- Looking for linux/videodev2.h - found -- Looking for sys/videoio.h -- Looking for sys/videoio.h - not found -- Looking for libavformat/avformat.h -- Looking for libavformat/avformat.h - found -- Looking for ffmpeg/avformat.h -- Looking for ffmpeg/avformat.h - not found -- checking for module 'tbb' -- package 'tbb' not found [...]

Could you explain how can I do this? Thanks!

Try creating opencv with TBB build enabled (BUILD_TBB = true), works for me on odroid-x2:

 cmake -D CMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/usr/local/opencv-2.4-ec15d6f383e0aae -DBUILD_TBB:BOOL="1" -DWITH_TBB:BOOL="1" .. make -j 4

If you run make install, be sure to copy the file. /lib/libtbb.so somewhere where you can find it, otherwise opencv will just leave it there.
