将lua嵌入到c ++中，但是外部问题无法解决：floor，freopen和strcoll

编程问答 2022-08-14

问题描述

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，__imp_floor和__imp_strcoll）。

lua在其自己的项目中作为静态c库进行编译并链接到主项目，但是使用luaL_newstate();时，我得到freopen(...)，floor(...)和{{ 1}}。

我的最佳猜测是此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，但是由于我经常在整个操作系统上处理该项目，因此无法正常显示premake很多问题。 我希望对缩小问题范围有任何想法。

lua的预制：

strcmp(...)

解决方案的相关预制件：

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"

lua.hpp仅包含在workspace "solution" architecture "x86_64" startproject "test" configurations { "Debug","Release" } flags { "MultiProcessorCompile" } outputdir = "%{cfg.buildcfg}-%{cfg.system}-%{cfg.architecture}" IncludeDir = {} IncludeDir["GLFW"] = "engine/vendor/GLFW/include" IncludeDir["Glad"] = "engine/vendor/Glad/include" IncludeDir["ImGui"] = "engine/vendor/imgui" IncludeDir["glm"] = "engine/vendor/glm" IncludeDir["stb_image"] = "engine/vendor/stb_image" IncludeDir["lua"] = "engine/vendor/lua" group "dependencies" include "engine/vendor/GLFW" include "engine/vendor/Glad" include "engine/vendor/imgui" include "engine/vendor/lua" group "" project "engine" location "engine" kind "StaticLib" language "C++" cppdialect "C++17" staticruntime "on" targetdir ("bin/" .. outputdir ..
