C++ 通过Xcode在OS X 10.11上构建OpenCV程序时出错

我按照以下说明在Mac上安装和构建OpenCV 3：

我成功地（从命令行）构建了文章底部包含的示例程序

然后我在这里阅读了作者的第二篇文章：-我注意到我使用的是Xcode 7.2而不是6.1，但是所有的对话框和步骤似乎都很好

…除了建筑

用上面的文章中包含的简单C++程序，我得到了这些生成错误：

Xcode显示20个错误，所有错误都来自以下形式的

cstring.h

它还给了我

如果您试图构建一个非常愚蠢的文件，而该文件只是

#include

和

int main（）{return 0；}

，那么会发生什么？如果没有

main.cpp

，很难判断错误在哪里。我要做的第一件事是尝试

使用namespace std@user4581301我已经更新了我的question@QuangHoang我已经更新了我再次询问的问题，因为这将有助于判断这是Open CV中的包含顺序问题还是编译器配置错误，当编译
include int main（）{return 0；}
时会发生什么？您是否得到相同的错误集？如果没有，我会开始沿着包含轨迹往回走，直到它断裂。不会解决问题，但会减少问题面积。
