Multiple definition of main Error

Question

when I compile my project, I get the following error.

error:Multiple definition of main() what is the problem?

Here is the code:

int main(int argc, char *argv[])
{
  QCoreApplication a(argc, argv);

myserver server;
server.startserver();

return a.exec();
}

Is this the only source file? Try looking at http://stackoverflow.com/questions/21508654/multiple-definition-of-main — rcmgleite, Nov 30 '15 at 12:12
You are compiling the file that contains `main` twice. Stop doing that. — Jonathan Wakely, Nov 30 '15 at 12:14

That means in your program you have at least two functions named main. Search for main in your source files and eliminate one or more (by renaming/refactoring for example).

You can have only one function called main in a C/C++ program.
