c++ - 无法让谷歌测试工作

Question

#include "gtest/gtest.h"

TEST(BattleUnitTest, CountryReturnsProperName) {
    EXPECT_EQ(1, 1);
}

int main(int argc, char* argv[]) {
    testing::InitGoogleTest(&argc, argv);
    return RUN_ALL_TESTS();
}

我似乎无法让谷歌测试工作。我运行 Nuget 包管理器来获取 gtest。它一直给我这些错误:

我可以发布所有错误，但几乎所有错误都与 LNK2019 有关。有谁知道如何解决这些错误？

我遇到了这个问题，但我的链接器设置没有任何问题。我最终找到了这篇文章 PrintTo link issue :

This was indeed caused by the mismatching /Zc:wchar_t setting. I failed to mention in the previous post that I had made that example code as Qt Console Application project (with Qt Add-in 1.1.9). Apparently the wchar_t setting is set to 'no' with that project template, while Google Mock's project setting is set to 'yes' by default. When I recompiled Google Mock with the setting set to 'no' the linker problem went away.

当我将设置“Treat WChar_t As Built in Type”更改为“Yes/Zc:wchar_t”时，构建工作正常。
