安裝Msys2環境
https://www.msys2.org/
按照上面官網提示配置gcc環境
修改源：進入msys64/etc/pacman.d/, 需要修改三個檔案, 都新增在Server列表第一行（不介意速度可省）

##mirrorlist.mingw32
Server = http://mirrors.ustc.edu.cn/msys2/mingw/i686/

##mirrorlist.mingw64
Server = http://mirrors.ustc.edu.cn/msys2/mingw/x86_64/

##mirrorlist.msys
 

Server = http://mirrors.ustc.edu.cn/msys2/msys/$arch/

1.Update the package database and base packages. Unless your setup file is very recent, it will take two steps. First run pacman -Syu

pacman -Syu

2.Run “MSYS2 MSYS” from Start menu. Update the rest of the base packages with pacman -Su

pacman -Su

3.Now MSYS2 is ready for you. You probably will want to install some tools and the mingw-w64 GCC to start compiling:

pacman -S --needed base-devel mingw-w64-x86_64-toolchain
Enter a selection (default=all): all
##預設安裝全部

4.To start building using the mingw-w64 GCC, close this window and run “MSYS MinGW 64-bit” from Start menu. Now you can call make or gcc to build software for Windows
如下可編譯Java本地方法

cygpath -w $(pwd
