visual-studio-2005 - Visual Studio 2005 中的 LNK 2005 错误

Question

我在 Windows XP 上使用 Visual Studio 2005。
我正在尝试使用“Google Test”框架。但是由于链接器错误，我无法仅进行一项测试。

我在 Debug模式下使用/MDd 选项构建了 Google Test 源文件
比我创建了新项目。
然后做了this link中写的步骤到项目属性文件。

比我尝试使用/MDd 选项在 Debug模式下构建并发生以下错误。
你能帮忙吗？
谢谢你。

 #include "gtest/gtest.h"
TEST(sample_test_case, sample_test)
{
    EXPECT_EQ(1, 1);
}

int main(int argc, char** argv) 
{ 
    return 1;
}

Answer 1

通过工作时间，我通过添加解决了这个问题

“配置属性 -> 链接器 -> 忽略特定库”

“msvcprtd.lib；MSVCRTD.lib”库。
