是否有其他方法将.dll文件从一个项目复制到我的启动项目中的可执行文件旁边

Question

我正在使用Premake5来构建C Visual Studio 2019应用程序引擎。我需要弄清楚为什么在使用Premake5构建项目后它不起作用。

我试图将体系结构更改为x64，但它坚持CFG.System是X86_64。

workspace "Engine_Autry"
    architecture "x64"

    configurations
    {
        "Debug",
        "Release",
        "Dist"
    }
outputdir = "%{cfg.buildcfg}-%{cfg.system}-%{cfg.architecture}"
project "Engine"
    location "Engine"
    kind "SharedLib"
    language "C++"
    targetdir ("bin/" .. outputdir .. "/%{prj.nam}")
    objdir ("bin-int/" .. outputdir .. "/%{prj.nam}")
    files
    {
        "%{prj.name}/src/**.h",
        "%{prj.name}/src/**.cpp"
    }
    includedirs
    {
        "%{prj.name}/vendor/spdlog/include"
    } 
    filter "system:windows"
        cppdialect "C++17"
        staticruntime "On"
        systemversion "latest"
        defines
        {
            "APP_PLATFORM_WINDOWS",
            "APP_BUILD_DLL"
        }
        postbuildcommands
        {
            {"{COPY} %{cfg.buildtarget.relpath} ../bin/" .. outputdir .. "/Sandbox"}
        }

    filter "configurations:Debug"
        defines "APP_DEBUG"
        symbols "On"
    filter "configurations:Release"
        defines "APP_RELEASE"
        optimize "On"
    filter "configurations:Dist"
        defines "APP_DIST"
        optimize "On"

project "Sandbox"
    location "Sandbox"
    kind "ConsoleApp"
    language "C++"
    targetdir ("bin/" .. outputdir .. "/%{prj.nam}")
    objdir ("bin-int/" .. outputdir .. "/%{prj.nam}")
    files
    {
        "%{prj.name}/src/**.h",
        "%{prj.name}/src/**.cpp"
    }
    includedirs
    {
        "Engine/vendor/spdlog/include",
        "Engine/src"
    } 
    links
    {
        "Engine"
    }
    filter "system:windows"
        cppdialect "C++17"
        staticruntime "On"
        systemversion "latest"
        defines
        {
            "APP_PLATFORM_WINDOWS"
        }

    filter "configurations:Debug"
        defines "APP_DEBUG"
        symbols "On"
    filter "configurations:Release"
        defines "APP_RELEASE"
        optimize "On"
    filter "configurations:Dist"
        defines "APP_DIST"
        optimize "On"   

它在我使用Premake5构建引擎之前正在工作。

Error   MSB3073 The command "IF EXIST ..binDebug-windows-x86_64Engine.dll (xcopy /Q /E /Y /I ..binDebug-windows-x86_64Engine.dll ..binDebug-windows-x86_64Sandbox > nul) ELSE (xcopy /Q /Y /I ..binDebug-windows-x86_64Engine.dll ..binDebug-windows-x86_64Sandbox > nul)

我遵循Thecherno的教程时也有相同的问题。

有两个问题引起了这个问题：

1. 在我的后构建命令中，目录不正确。在您的情况下，目录是正确的。
2. 将沙箱设置为启动项目。我认为您在重建和重新装载Visual Studio后忘了这样做。

尝试一下，让我知道。
