c++ - 将 lua 嵌入到 C++ 中但得到未解决的外部：floor、freopen 和 strcoll

Question

我将 lua 嵌入到 c++ vs2019 解决方案中，它导致将错误链接到基本 c 库（__imp_freopen和__imp_floor）__imp_strcoll。

lua 在它自己的项目中编译为静态 c 库并链接到主项目，但是使用时luaL_newstate();我得到未解析的外部符号freopen(...),floor(...)和strcmp(...).

我最好的猜测是这个错误来自我的构建系统（premake5），因为当我使用 vs2019 手动添加项目时，没有链接错误，但由于我经常跨操作系统处理这个项目，所以 premake 不能正常工作会带来很多问题。我将不胜感激有关如何缩小问题范围的任何想法。

lua 的预制：

project "lua"
    kind "StaticLib"
    language "C"

    targetdir ("bin/" .. outputdir .. "/%{prj.name}")
    objdir ("bin-int/" .. outputdir .. "/%{prj.name}")

    files
    {
        "src/**.c",
        "src/**.h",
        "src/lua.hpp"
    }

    excludes
    {
        "src/lua.c",
        "src/luac.c"
    }

    filter "configurations:Debug"
        runtime "Debug"
        symbols "on"

    filter "configurations:Release"
        runtime "Release"
        optimize "on"

解决方案的相关预制：

workspace "solution"
    architecture "x86_64"
    startproject "test"

    configurations
    {

lua.hpp 只包含在 lua_script.cpp 中class lua_script {...};
