Question

我正在尝试通过这些说明在我的Mac Air（与Lion）上安装opencv2。

http://www.guidefreitas.com/installing-opencv-2-4-2-on-mac-osx-mountain-lion-with-python-support

我已成功使用

制作opencv2

make j8

但是，运行sudo make install会产生一个奇怪的错误，指出未定义numext的方式。

这个错误是什么意思？我觉得它与Eigen库有关。我尝试重塑Eigen库。反过来，这产生了另一个涉及glew，过剩和OpenGL的错误。感觉就像走了一个兔子洞。

有谁知道Eigen库中的错误来自哪里？

Answer 1

看来你正在混合两种不同版本的Eigen。此外，让我再次回忆一下，不必编译Eigen。

Answer 2

我的实际解决方案是创建到eigen3的符号链接，例如：

$ ln -s /usr/local/include/eigen3/unsupported /usr/local/include/

Answer 3

这让我发疯了......但最后它只是一个：

brew install eigen

opencv构建正确！

为什么我不能安装python opencv2？
