Hello Derek, I'm trying to cross compile OpenCV (2.4.0) for ARM. I'm using Linaro toolchain and CMake (http://processors.wiki.ti.com/index.php/Building_OpenCV_for_ARM_Cortex-A8), but I get the following error: .../ffmpeg_codecs.hpp:78:36:fatal error: libavformat/avformat.h: No such file or directory compilation terminated. I have installed libavformat-dev and configured CMake again, but I get the same error. Which version of CMake you are using? How you write de toolchain.cmake? How do you set the (-O3 -mfloat-abi=hard -ftree-vectorize -funroll-loops) C/CXX flags? I'm using CMake2.8.7. Thanks in advance. _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
