Help with this library

[davinciomare]

Please how i can include this library:

MSVCRT.lib(crtexe.obj):-1: error: LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup

Thanks in advance.

Your sources should include a definition of a function main().

[davinciomare]

i included main function:
int main(int argc, char *argv[])
{

QApplication a(argc, argv);
MainWindow w;
return a.exec();
}
