问题描述

编译opencv 3.2 报错

/usr/include/c++/7/cstdlib:75:15: fatal error: stdlib.h: No such file or directory
 #include_next <stdlib.h>
               ^~~~~~~~~~

解决办法

在/build目录下的cmake中添加指令-D ENABLE_PRECOMPILED_HEADERS=OFF
比如我的

cmake -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX=/usr/local \
    -D INSTALL_C_EXAMPLES=ON \
    -D INSTALL_PYTHON_EXAMPLES=ON \
    -D OPENCV_GENERATE_PKGCONFIG=ON \
    -D ENABLE_PRECOMPILED_HEADERS=OFF \
    -D OPENCV_EXTRA_MODULES_PATH=~/opencv/opencv_contrib/modules \
    -D BUILD_EXAMPLES=ON ..
