Hi,
i try to build OpenCV on my Ubuntu 12.4 (64 bit) as 32 bit library. I was setting the compiler flags like this:
cmake -G "Unix Makefiles" -D CMAKE_C_FLAGS=-m32 -D CMAKE_CXX_FLAGS=-m32 ..
Then i started to build the project. After some time i got this:

I searched for the 32 bit version of this librariess, but i only in some cases successful. I would be nice if somebody has an idea what i can do?
