C++ cygwin错误下的Boost

命令行是

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

以下是错误消息：

任何帮助，我都不明白为什么会选中python27目录。

看起来python27文件夹包含

mingw

-这是

cygwin

备选方案。可能默认的头搜索路径设置为

mingw

的dir（c:/python27/egg info/mingw/usr/lib/gcc/。/../x86_64-w64-mingw32/include/）

检查是否设置了以下环境变量：

CPATH
C_INCLUDE_PATH
CPLUS_INCLUDE_PATH
OBJC_INCLUDE_PATH

您还可以尝试使用以下工具进行编译： 1）

-nosdinc

忽略默认包含目录的选项

---

2）

-v

到verbose

g++

output

谢谢，我想我已经安装了EnThound Python，它包含了cygwin的另一个副本。
