Question

我正在尝试在CentOS 5.8上安装OpenCV 2.4.2，但是我收到以下错误

[ 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

diff -crB OpenCV-2.4.2.orig/modules/features2d/src/freak.cpp OpenCV-2.4.2/modules/features2d/src/freak.cpp
