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

  ...a bunch of similar errors

我对 C++ 没有太多经验，所以我不确定这个错误是怎么回事。有小费吗？

进入build目录后，以下是命令：

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。首先尝试一下，如果有效，您可以尝试更改 ccmake 中的选项。您不应该在 cmake 之前运行 ccmake。它只是 cmake 的一个交互式前端。如果您使用 ccmake 生成 make 文件，则不应运行 cmake。直接从 ccmake 去制作。
