前言

  • 搜了许多资料，觉得vscode调式c程序的教程有点杂，所以写下这篇博客，使用vscode调用lua源码，版本是lua5.3.6,下载地址为http://www.lua.org/versions.html

正文

  • vscode的插件准备（有安装code runner的需要禁止用）

  • 准备一个vscode工程目录如下：

  • 把lua-5.3.6的源文件复制一份到include文件夹和src，然后使用del *h或del *c删除对应不需要的文件夹。如图：

  • 然后需要注释掉lua.c源码的int main和luac.c源码的int main的入口

  • vscode调式c配置，首先使用shift+ctrl+p,如下图所示，会生成c_cpp_properties.json文件，如图

  • 在``文件里添加这一条规则，这样头文件不会是红线了

  • 接下来配置task.json

            }
        ]
    }

    int main()
    {
        lua_State* L = luaL_newstate();
        luaL_openlibs(L);

        luaL_dofile(L, "testlua.lua");

        lua_close(L);

        return 0;
    }

    print("xxx")

  • 开始调试

    • 先打断点，如图
