Similar problem here: Trying to build OpenCV 2.4.5 with TBB support using MinGW 4.7.2 or 4.8.1 I can build TBB if I do it separtely, but I cannot configure OpenCV to use the TBB I built: it downloads some other version, and fails compiling saying: A) That I should activate -std=c++11 B) If I activate c++11 (CMAKE_CXX_FLAGS), it says "error: 'thread' is not a member of 'std'"

I tried to add other flags, copying them from the previously successful separated build of TBB, but with no effect.

I tried In short: try first to add other flags, copying them from the previously successful separated build of TBB, but with no effect.tbb separately, then see how to proceed.
