Compliling OpenCV 3 with TBB on Raspberry Pi 2

Question

Has anyone successfully installed opencv 3.0.0 with TBB enabled on the latest rasperian on pi 2?

I followed the guide here https://www.raspberrypi.org/forums/view ... v3#p761255

The only differences I made was to the enable TBB via cmake... added BUILD and WITH TBB options as shown..

cmake -D CMAKE_BUILD_TYPE=RELEASE -D BUILD_TBB=ON -D WITH_TBB=ON -D CMAKE_INSTALL_PREFIX=$(python3 -c "import sys; print(sys.prefix)") -D PYTHON_EXECUTABLE=$(which python3) ..

I am patched current, all dependencies installed as far as I can tell.. cmake reports its going to install and old version of tbb...

-- Use TBB: YES (ver 4.1 interface 6102)

The make process fails with a linking problem I don't understand fully,

Things I've tried...

1. I thought a newer version of TBB may help... so after failing as shown above I hacked the opencv installer and changed the TBB load to the latest release... no joy.. same problem.
2. Trying to make it finish I found I could update the cmakelists.txt in the opencv/apps folder not install the annotation app.. Still failed. but on a different app.. traincascade... removed it.. same... remove the last app in the directory from CmakeLists.txt and it succeeded. However when attempting to link my c app it complains with the unresolved references on imgproc :|
3. Ran ccmake ../ and turned of build tests and other extras... no joy.

Appreciate any help I can .. want tbb to use the four cores for my pi if i can!
