Xcode：cstdlib在全局命名空间

Question

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

错误：

Answer 1

我发现我犯了什么错误。 在标头搜索路径中：我使用递归的/usr/local/include。 我改成之后 /usr/local/include non-recursive /usr/local/include/opencv non-recursive /usr/local/include/opencv2 non-recursive

有效。但我仍然不知道为什么递归版本会导致错误。
