如何在 premake5 和 VS2019 中使用 googletest

问题描述

我一直在尝试将 googletest 集成到我的解决方案中，但我遇到了令人讨厌的链接器错误或根本无法添加它。

googletest 作为子模块添加：git submodule add 'https://github.com/google/googletest.git'

一直在尝试像这样配置 premake5：

...
project "libtest"
    location "libtest"
    kind "ConsoleApp"
    language "C++"

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

    files
    {
        "%{prj.name}/src/**.h","%{prj.name}/src/**.cpp","libtest/vendor/googletest/googletest/**.h","libtest/vendor/googletest/googletest/**.hpp","libtest/vendor/googletest/googletest/src/gtest-all.cc"
    }

    includedirs
    {
        "mylib",// DLL
        "libtest/vendor/googletest/googletest/include/gtest","libtest/vendor/googletest/googletest/include","libtest/vendor/googletest/googletest"
    }
 ...

然后我得到 LNK2019 unresolved external symbol main referenced in function "int __cdecl invoke_main(void)" (?invoke_main@@YAHXZ) libtest C:\dev\mylib\libtest\LIBCMTD.lib(exe_main.obj) 1

解决方法

终于解决了:)

添加一些额外的文件：

int main(int argc,char** argv)
{
    testing::InitGoogleTest(&argc,argv);

    return RUN_ALL_TESTS();
}

修复链接问题，并清理：

"libtest/vendor/googletest/googletest/include/gtest","libtest/vendor/googletest/googletest/include","libtest/vendor/googletest/googletest"

到这里

"libtest/vendor/googletest/googletest/include","libtest/vendor/googletest/googletest/"

足够了。
