Question

我正在尝试在OS X 10.6.8上构建OpenCV。我下载了源代码，然后创建了一个构建目录，然后运行ccmake进行配置，然后运行cmake。当我运行make时，我得到以下输出：

[laptop] build$ pwd
/Users/jesse.aldridge/OpenCV-2.4.2/build
[laptop] build$ make

我没有很多使用C ++的经验，所以我不确定这个错误究竟是什么。有什么提示吗？

进入build目录后，会出现以下命令：

cmake -G "Unix Makefiles" ..
make -j8
sudo make install

这一直对我有用。不要忘记cmake命令末尾的两个点。首先尝试，如果有效，您可以尝试更改ccmake中的选项。你不应该在cmake之前运行ccmake。它只是cmake的交互式前端。如果您使用ccmake生成make文件，则不应运行cmake。只需直接从ccmake进行制作。
