在 C 中嵌入 Lua 5.1，无法调试，VSCode 中的预启动任务错误

Question

我正在尝试了解如何将 Lua 5.1 嵌入到 C 文件中，以便创建一个最小的可重现示例来尝试解决另一个问题（thread here). I was following this simple tutorial 但一旦调试器到达 lua_State *L = luaL_newstate();，它给我错误 预启动任务 'C/C++:gcc.exe build active file' 以退出代码 -1 终止。

如何修复此错误？我尝试搜索答案，但找不到符合这种情况的任何内容，我不知道在 C++ 中嵌入 Lua 是否与 C 不同。我在 Windows 上使用 VSCode 10.

这是我在 C 文件中尝试的代码：

#include <lua.h>
#include <lualib.h>
#include <lauxlib.h>

int main(void) {
  lua_State *L = luaL_newstate();
  return 0;
}

这是我的 launch.json:

问题原来是缺少链接器信息。很难找到特定于在 Windows 上使用带有 VSCode 的 GCC 以在 C 中嵌入 Lua 的信息，并且有一段时间我不确定这些命令应该去哪里。由调试器自动创建的 tasks.json 不包含此信息。我必须在 "args" 部分的括号内输入 "-LC:/MyLibs/lua5.1",、"-IC:/MyLibs/lua5.1/include", 和 "-llua5.1",。这是文件现在的样子（自从第一次发布以查看文件夹名称中的空格是否使 GCC/GDB 起作用以来，我已将 minGW 和 MyLibs 移到“程序文件”之外）：

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: gcc.exe build active file",
            "command": "C:/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/bin/gcc.exe",
            "args": [
                "-g",
                "${file}",
                "-LC:/MyLibs/lua5.1",
                "-IC:/MyLibs/lua5.1/include",
                "-llua5.1",
                "-o",
                "${fileDirname}\${fileBasenameNoExtension}.exe"
            ],
            "options": {
                "cwd": "C:/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/bin"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
