Question

命令行是

g++ -c -Wall -I "C:/cygwin/usr/include/" test.cpp 

这里的错误消息：

C:/cygwin/usr/include/stdint.h:62:22: error: conflicting declaration 'typedef unsigned int uintptr_t'

任何帮助，我不明白为什么python27目录进行检查。

Answer 1

看起来像python27文件夹包含mingw - 这是cygwin替代。可能默认标题搜索路径设置为mingw的dir（c：/ python27/egg-info/mingw/usr/lib/gcc /../../ x86_64-w64-mingw32/include /）。

检查是以下环境变量设置：

CPATH 
C_INCLUDE_PATH 
CPLUS_INCLUDE_PATH 
OBJC_INCLUDE_PATH 

你也可以尝试用编译： 1）-nostdinc选择忽略默认include目录 2）-v对详细g++输出
