1. 检查本机有没有安装GCC，没有的话先进行安装
2. 选择 sublime 的Tools->Build System->New Build System，建立配置文件，文件命名为C.sublime-build，文件内容如下：
{
"cmd": ["gcc","-Wall", "${file}", "-o", "${file_path}/${file_base_name}"],
"file_regex": "^(..[^:]*):([0-9]+):?([0-9]+)?:? (.*)$",
"working_dir": "${file_path}",
"selector": "source.c, source.c++",
"encoding":"utf8",
"variants":
[
{
"name": "Run",
"cmd": ["cmd", "/c", "gcc", "-Wall","${file}", "-o", "${file_path}/${file_base_name}", "&&", "cmd", "/c", "${file_path}/${file_base_name}"]
},
{
"name": "RunInCommand",
"cmd": ["cmd", "/c", "gcc", "-Wall","${file}", "-o", "${file_path}/${file_base_name}", "&&", "start", "cmd", "/c", "${file_path}/${file_base_name} & echo.&pause"]
},
{
"name": "RunInShell",
"shell_cmd": " start cmd /c \"\"${file_path}/${file_base_name}\"&pause\" "
}
]
}
3. 写好C程序后，快捷键ctrl+b就可以执行该程序。
