  4. 配置完成 临时文件将保存在Debug文件夹中

  • Windows下的配置

安装LLVM

LLVM Download Page
http://releases.llvm.org/download.html
，在网页中找到适用于Windows 64位的最新预编译版本，不需要下载sig签名文件。安装过程中注意选择为所有用户安装，这样会为你添加到环境变量。 这两步完成以后打开cmd，输入clang应该可以看到如下输出。

安装MinGW-w64

MinGW-w64 - for 32 and 64 bit Windows
https://sourceforge.net/projects/mingw-w64/
，安装时注意选择体系架构为x86_64。由于网络原因，你可能不能把它下载下来，经过一点探索，安装程序需要下载一个叫做x86_64-7.1.0-release-posix-seh-rt_v5-rev2的文件，其实我们可以直接在SourceForge上搜到这个
MinGW-w64 - for 32 and 64 bit Windows
https://sourceforge.net/projects/mingw-w64/
，到里面选择第一个下载。下载完成后解压里面的mingw64文件夹中的内容到你安装LLVM的同一个目录合并，合并里面所有文件夹，不会有冲突。
打开终端验证是否能够打开gdb.exe.
