Errore LNK 2005 in Visual Studio 2005

Question

Uso Visual Studio 2005 in Windows XP. Sto provando a utilizzare il framework "Google Test". Ma non sono riuscito a fare un solo test a causa di errori del linker.

Ho creato i file di origine di Google Test con l'opzione/MDd in modalità di debug rispetto a quando ho creato un nuovo progetto. Quindi ha eseguito i passaggi scritti in this link nel file delle proprietà del progetto.

Rispetto a quando ho tentato di creare in modalità Debug con l'opzione/MDd e si sono verificati i seguenti errori. Potete aiutare per favore? Grazie.

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

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

Con ore di lavoro, ho risolto il problema aggiungendo

"Configurazione Proprietà -> Linker -> Ignora libreria specifica"

"msvcprtd.lib; MSVCRTD.lib" librerie.
