MATLAB R2018B 说使用的MINGW编译器版本

>gcc --version
gcc (x86_64-posix-seh-rev2, Built by MinGW-W64 project) 6.3.0

使用mingw.mlpkginstall为MATLAB R2018B安装MINGW编译器,在命令行显示gcc的版本号,发现对应的gcc 6.3.0(x86_64-posix-seh-rev2, Built by MinGW-W64 project),由于MATLAB R2018B中使用mingw.mlpkginstall安装速度十分缓慢,并且失败机率很大,大家可以直接去网站上下载文件:x86_64-6.3.0-release-posix-seh-rt_v5-rev2.7z,下载地址为:

https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/6.3.0/threads-posix/seh/

下载完成后,解压缩到C:\ mingw-w64目录中:

1.将C:\ mingw-w64\mingw64加到系统路径PATH中;

2.设置环境变量MW_MINGW64_LOG,变量值为C:\ mingw-w64\mingw64

3.在MATLAB命令行中setenv('MW_MINGW64_LOC', 'C:\ mingw-w64\mingw64')

4.在MATLAB命令行中:mex -setup,选择MINGW C++编译器即可.
