我正在尝试安装 opencv 3.1。我已经下载了 opencv (https://github.com/Itseez/opencv_contrib/archive/3.1.0.zip）并解压。现在根据各种教程，我应该能够使用
$cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_PYTHON_EXAMPLES=ON -D INSTALL_C_EXAMPLES=OFF -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.1.0/modules -D PYTHON_EXECUTABLE=~/.virtualenvs/cv/bin/python -D BUILD_EXAMPLES=ON ..
$make -j $(nproc)
这很快就会失败并显示以下输出：
$ make -j $(nproc)

所以它说我使用了错误版本的 gcc，但是我已经通过替代方案使用了 4.9
$ sudo update-alternatives --config gcc
There are 3 choices for the alternative gcc (providing /usr/bin/gcc).
Selection Path Priority Status

0 /usr/bin/gcc-6 60 auto mode
* 1 /usr/bin/gcc-4.9 20 manual mode
2 /usr/bin/gcc-5 25 manual mode
3 /usr/bin/gcc-6 60 manual mode
这里还有 cmake 输出

其他地方有人提出，如果使用 opencv 4.9 安装这个，则可能会出现此问题，但这会再次破坏 cuda。（并且 make clean 或 rm build -r 也无法解决问题）
