运行 make CentOS 时出现 OpenCV 错误

Question

我尝试在 CentOS 5.8 上安装 OpenCV 2.4.2，但出现以下错误

[ 34%] Built target opencv_test_highgui
[ 34%] Building CXX object modules/features2d/CMakeFiles/opencv_features2d.dir/src/freak.cpp.o

make[1]: *** [modules/features2d/CMakeFiles/opencv_features2d.dir/all] Error 2
make: *** [all] Error 2

我在 cmake 上运行了以下命令

 cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_EXAMPLES=OFF WITH_CUDA=OFF ..     

谢谢。

问题已解决。

我将以下补丁应用于 ~/Downloads/OpenCV-2.4.2/modules/features2d/src/freak.cpp
