我使用 MinGW+msys。
我正在尝试按照以下说明安装 OpenCASCADE。
https://sites.google.com/site/philippeguerville/home/build-opencascade-for-windows-with-mingw
我已经安装了libpng freeglut FreeImage freetype。
gl2ps并且oce已经离开了。
现在我在makegl2ps 时遇到问题，出现如下错误。

_cpu_features_init _CRT_fmode _CRT_glob那些定义在哪里？
有没有要定义的头文件_cpu_features_init _CRT_fmode _CRT_glob？
我make g1lps用以下命令。
cmake -G "MSYS Makefiles" -DCMAKE_INSTALL_PREFIX=/usr/local -DZLIB_INCLUDE_DI
