无法打开OpenCV

Question

我从OpenCV网站下载OpenCV 2.3.1并将其解压到/usr/share/src。我该文件夹生成make文件中跑sudo cmake .，然后跑去“sudo make”我发现了以下错误：

Answer 1

尝试指导下使用CMake的构建在第2节的the Wiki：

mkdir build 
cd build 
cmake -G "Unix Makefiles" .. 
make -j8 
sudo make install 

Answer 2

你可能有更早的冲突安装MacPorts。 运行：

port installed opencv 

如果该发现的OpenCV的另一个版本则使用：

sudo port deactivate opencv 

然后再次运行make。

注意：它会制动任何取决于您以前的opencv端口安装。因此，您需要再次激活旧的或调整依赖关系才能使用2.3.1。
