cstdint中的错误:全局命名空间中没有名为xxx的成员
什么会导致这样的错误？我向Xcode添加了一个空项目,在Header Search Paths中添加了/ usr/local/lib,并添加了一些opencv库.Building出现了这些错误:
UPDATE
看来stdint.h确实安装在我的系统上.我在OS 10.9上运行,所以像int_least16_txcode 这样的类型在全局命名空间中找不到似乎是定义的.
typedef int16_t int_least16_t;.

感谢@nm,我了解到直接安装任何东西/usr/local都会因为随之而来的版本地狱而被打破.我很可能不得不在坏的一些源/usr/local/include,所以当我更换usr/local/include用/usr/local/Cellar/opencv/2.4.8.2/include/opencv2的(因为我安装使用BREW的OpenCV) Xcode > Build Settings > Header Search Paths(递归真)一切正常.
