为什么我不能安装python opencv2?

I am trying to install opencv2 on my Mac Air (with Lion) via these instructions.

我已经成功地完成了opencv2。

make j8

However, running sudo make install produces an odd error noting how numextisn't defined.

然而，运行sudo使安装产生一个奇怪的错误，注意到numextisn没有定义。

What does this error mean? I feel that it has to do with the Eigen library. I tried remaking the Eigen library. In turn, this produced another error involving glew, glut, and OpenGL. It feels like going down a rabbit hole.

这个错误是什么意思?我觉得这与本处图书馆有关。我试着重新设计了这个图书馆。反过来，这又产生了另一个涉及glew、过剩和OpenGL的错误。感觉就像掉进了一个兔子洞。

Does anyone know where the error in the Eigen library comes from?

有谁知道本图书馆的错误是从哪里来的?

3 个解决方案

#1

It seems you are mixing two different versions of Eigen. Moreover, let me recall again that Eigen does not has to be compiled.

似乎你在混合两种不同的特征。此外，让我再次回顾一下，本征不需要编译。

#2

My actual solution was to create symbolic links to eigen3, such as:

我的实际解决方案是创建特征3的符号链接，例如:

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

#3

This was driving me crazy... but in the end it was just a:

这让我快要发疯了……但最后，它只是一个:

brew install eigen

And opencv built correctly!

和opencv建立正确!
