Question

我正在尝试更新最新的opencv formula（截至编写时，此公式安装opencv 2.4.7）以构建最新版本的opencv（2.4.8）。

我做的第一件事是brew edit opencv，并将网址更改为“https://github.com/Itseez/opencv/archive/2.4.8.tar.gz”并更新校验和。我预计我可能不得不处理一些已建立的问题，但我看到的问题似乎是在公式运行时发生的。

具体来说，当我运行brew upgrade opencv（或取消链接并运行brew install opencv）时，我收到以下消息：

==> Downloading https://github.com/Itseez/opencv/archive/2.4.8.tar.gz
Already downloaded: /Library/Caches/Homebrew/opencv-2.4.8.tar.gz

Python似乎没有被加载。我也对弃用警告感到困惑;我发现的一切都表明python公式是我应该使用的公式。从这个link判断，depends_on :python依赖似乎应该有效（当我尝试使用之前的2.4.7.1公式时，显然也是如此）。

供参考，以下是我的环境变量：

和python（自制）版本 python --version #=>Python 2.7.6

brew doctor输出给我一个关于乘客配置文件的警告（不应该影响opencv的构建）以及opencv取消链接的警告（我取消链接以尝试运行brew install opencv）< / p>

提前感谢您的帮助。

Answer 1

我有同样的错误。我不明白为什么在公式文件中没有正确定义“incdir”或其他变量。但我通过编辑opencv公式文件解决了这个错误，如下所示（直接设置每个路径）

（约50行）

DPYTHON_INCLUDE_DIR =的/ usr /本地/地窖/蟒/ 2.7.6 /框架/ Python.framework /版本/ 2.7 /包含/ python2.7

DPYTHON_LIBRARY =的/ usr /本地/地窖/蟒/ 2.7.6 /框架/ Python.framework /版本/ 2.7 / LIB / libpython2.7.dylib

DPYTHON_EXECUTABLE =的/ usr / local / bin中/蟒

Answer 2

我通过回滚到早期的自制软件版本，然后安装opencv，然后回到当前版本来解决这个问题。
