WIN10 MSYS2 环境配置

MSYS

1. 安装 MSYS2, MingW-64, DOWNLOAD

i686 和 x86_64 任选一个安装， 在安装目录下会有一个MSYS2.EXE MINGW32.EXE MINGW64.EXE

安装软件使用MSYS2.EXE, 编译gcc时，32位使用MINGW32.EXE，64位使用MINGW64.EXE，安装完目录如下：

更新, 只要更新了 pacman 这个命令本身就会出现卡死的情况,这时要使用任务管理器关闭,然后再打开MSYS2再执行一次更新,这时可以正常执行下去

## 先执行下面的命令更新MYSYS2系统
pacman -Syu

2. 打开MSYS2.EXE，安装gcc 及相关工具

## 安装 gcc llvm clang 及相关库的命令如下：
pacman -Sy mingw32/mingw-w64-i686-gcc mingw32/mingw-w64-i686-gcc-ada mingw32/mingw-w64-i686-gcc-fortran mingw32/mingw-w64-i686-gcc-libgfortran mingw32/mingw-w64-i686-gcc-libs mingw32/mingw-w64-i686-gcc-objc mingw32/mingw-w64-i686-lcov mingw64/mingw-w64-x86_64-gcc mingw64/mingw-w64-x86_64-gcc-ada mingw64/mingw-w64-x86_64-gcc-fortran mingw64/mingw-w64-x86_64-gcc-libgfortran mingw64/mingw-w64-x86_64-gcc-libs mingw64/mingw-w64-x86_64-gcc-objc mingw64/mingw-w64-x86_64-lcov msys/gcc msys/gcc-fortran msys/mingw-w64-cross-gcc mingw32/mingw-w64-i686-clang mingw32/mingw-w64-i686-compiler-rt mingw32/mingw-w64-i686-lld mingw32/mingw-w64-i686-llvm mingw32/mingw-w64-i686-polly mingw64/mingw-w64-x86_64-clang mingw64/mingw-w64-x86_64-compiler-rt mingw64/mingw-w64-x86_64-lld mingw64/mingw-w64-x86_64-llvm mingw64/mingw-w64-x86_64-polly msys/clang-svn msys/lld-svn msys/llvm-svn  mingw32/mingw-w64-i686-gdb mingw32/mingw-w64-i686-gdbm mingw64/mingw-w64-x86_64-gdb mingw64/mingw-w64-x86_64-gdbm msys/cgdb msys/gdb msys/gdbm msys/libgdbm msys/libgdbm-devel  msys/sharutils msys/perl msys/make msys/icmake msys/cmake mingw32/mingw-w64-i686-cmake mingw32/mingw-w64-i686-dmake mingw32/mingw-w64-i686-make mingw64/mingw-w64-x86_64-cmake mingw64/mingw-w64-x86_64-dmake mingw64/mingw-w64-x86_64-make automake autogen python2 python3 mingw32/mingw-w64-i686-binutils mingw64/mingw-w64-x86_64-binutils msys/binutils msys/mingw-w64-cross-binutils  mingw32/mingw-w64-i686-clang-analyzer mingw32/mingw-w64-i686-clang-tools-extra mingw64/mingw-w64-x86_64-clang-analyzer mingw64/mingw-w64-x86_64-clang-tools-extra mingw32/mingw-w64-i686-yasm mingw64/mingw-w64-x86_64-yasm msys/yasm msys/yasm-devel mingw32/mingw-w64-i686-nasm mingw64/mingw-w64-x86_64-nasm msys/nasm  mingw32/mingw-w64-i686-dbus-glib mingw32/mingw-w64-i686-geocode-glib mingw32/mingw-w64-i686-glib-networking  mingw32/mingw-w64-i686-glib2 mingw32/mingw-w64-i686-glibmm mingw32/mingw-w64-i686-json-glib mingw32/mingw-w64-i686-jsonrpc-glib mingw32/mingw-w64-i686-libgda mingw32/mingw-w64-i686-libgit2-glib  mingw32/mingw-w64-i686-libgusb mingw32/mingw-w64-i686-libical-glib mingw32/mingw-w64-i686-libvirt-glib mingw32/mingw-w64-i686-taglib mingw32/mingw-w64-i686-template-glib mingw64/mingw-w64-x86_64-dbus-glib mingw64/mingw-w64-x86_64-geocode-glib mingw64/mingw-w64-x86_64-glib-networking mingw64/mingw-w64-x86_64-glib2 mingw64/mingw-w64-x86_64-glibmm mingw64/mingw-w64-x86_64-json-glib mingw64/mingw-w64-x86_64-jsonrpc-glib mingw64/mingw-w64-x86_64-libgda mingw64/mingw-w64-x86_64-libgit2-glib mingw64/mingw-w64-x86_64-libgusb mingw64/mingw-w64-x86_64-libical-glib mingw64/mingw-w64-x86_64-libvirt-glib mingw64/mingw-w64-x86_64-taglib mingw64/mingw-w64-x86_64-template-glib msys/glib2-devel msys/glib2-docs p7zip unrar diffutils subversion git emacs zip mingw32/mingw-w64-i686-libzip mingw64/mingw-w64-x86_64-libzip tar mingw32/mingw-w64-i686-nsis mingw64/mingw-w64-x86_64-nsis msys/autoconf msys/bison msys/cloog-devel msys/diffstat msys/dos2unix msys/gperf msys/groff msys/heimdal-devel msys/icu-devel msys/intltool msys/libbz2-devel msys/libcrypt-devel msys/libcurl-devel msys/libdb-devel msys/libgc-devel msys/libgcrypt-devel msys/libgnutls-devel msys/libnpth-devel msys/ncurses-devel msys/openssl-devel msys/patch msys/patchutils msys/swig mingw32/mingw-w64-i686-ctags mingw64/mingw-w64-x86_64-ctags mingw32/mingw-w64-i686-libtool  mingw64/mingw-w64-x86_64-libtool msys/libedit msys/libltdl msys/libtool mingw64/mingw-w64-x86_64-mcpp mingw32/mingw-w64-i686-mcpp mingw32/mingw-w64-i686-cppunit mingw64/mingw-w64-x86_64-cppunit mingw32/mingw-w64-i686-cppcheck mingw32/mingw-w64-i686-antlr4-runtime-cpp mingw32/mingw-w64-i686-cpptest mingw64/mingw-w64-x86_64-cppcheck mingw64/mingw-w64-x86_64-antlr4-runtime-cpp mingw64/mingw-w64-x86_64-cpptest msys/bisonc++ mingw32/mingw-w64-i686-flexdll mingw64/mingw-w64-x86_64-flexdll

安装完后配置fstab，添加/lib。之所以要添加这个是因为如果不配置/lib,后面gcc的configure无法进行下去，会提示 error: C++ preprocessor "/lib/cpp" fails sanity check 的错误，而这个错误是因为找不到/lib/cpp造成的，在日志中会出现: error: /lib/cpp :no such file or direcotry的错误

mkdir /lib
echo "C:/MSYS/MSYS32/mingw32/bin /lib" >> /etc/fstab

执行上面的步骤后，关闭所有命令行
