Building OpenCV in Mac Os X (10.9.1) - video library error

edit

Dear all,

I recently upgraded my gcc compiler to version (4.8.2). After trying to install OpenCV (2.4.8), I get some compiler errors when building the opencv_video library. The way I'm building the OpenCV library is as follows:

cd opencv-2.4.8
mkdir release
cd release/
cmake -D CMAKE_CXX_FLAGS="-I/opt/local/includes -L/opt/local/lib" -D CMAKE_INSTALL_PREFIX="/opt/local" -D CMAKE_BUILD_TYPE=Release -D CMAKE_VERBOSE_MAKEFILE=ON ..
make -j 4

The error message is given below and any feedback/suggestions are really welcomed :-) When following the same steps mentioned above for building the OpenCV library, but with using gcc 4.2.1, I didn't get any compilation problems and the library could be successfully installed.
