问题
I'm trying to compile OpenCV libs with TBB support for odroid U2 (with Quad core ARM Cortex-A9 MPCore). I have no problem with compile current OpenCV (from github) without TBB. And also I have no problem with compiling TBB libs fron sources - tbb41_20130116oss_src.tgz and I have successfully builded TBB libs:
root@odroid:~/src/tbb41_20130116oss/build/linux_armv7l_gcc_cc4.6_libc2.15_kernel3.0.63_release# ls

I can compile my own programm with g++ using this TBB libs, but I can't configure OpenCV to see this TBB libs:
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)

could you explain how I can do this? Thank you!
回答1:
Try building opencv with the included TBB build (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 do a make install, be sure to copy ./lib/libtbb.so to somewhere where it can be found, otherwise opencv just leaves it there.
