Xcode: cstdlib no member named "xxx" in the global namespace
提问by Dylan
I only change the search path to inform Xcode where opencv locates. Here's my search paths:
我只更改搜索路径以通知 Xcode opencv 所在的位置。这是我的搜索路径：
Framework search path: /usr/local/lib
Library search path: /usr/local/Cellar/opencv/2.4.11/lib
/usr/local/Cellar/opencv/2.4.11_1/lib
/user/local/lib
Header search path: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include
/usr/local/include
The errors:

I find what mistake I made.
In the Header search path: I use /usr/local/includewith recursive.
After I change it to
/usr/local/include non-recursive/usr/local/include/opencv non-recursive/usr/local/include/opencv2 non-recursive
我发现我犯了什么错误。在标题搜索路径中：我使用/usr/local/include递归。在我将其更改为
/usr/local/include non-recursive/usr/local/include/opencv non-recursive/usr/local/include/opencv2 non-recursive
It works. But I still don't know why the recursion version would cause errors.
有用。但是我仍然不知道为什么递归版本会导致错误。
