Erro LNK 2005 no Visual Studio 2005

Question

Eu uso o Visual Studio 2005 no Windows XP. Estou tentando usar a estrutura "Google Test".Mas não consegui fazer apenas um teste por causa de erros do linker.

Criei arquivos de origem do Google Test com a opção / MDd no modo de depuração Então criei um novo projeto. Em seguida, execute as etapas descritas neste link ao arquivo de propriedades do projeto.

Então tentei construir no modo de depuração com a opção / MDd e ocorreram os seguintes erros. Você pode ajudar por favor? Obrigado.

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

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

Com o horário de trabalho, resolvi esse problema adicionando

"Propriedades de configuração -> Linker -> Ignorar biblioteca específica"

Bibliotecas "msvcprtd.lib; MSVCRTD.lib".
