LIBCD.lib(crt0.obj) : error LNK2019: unresolved external symbol _main

I am quite experienced with vs.net 2003 and c# but fairly new to c++. I
have a test app in c++ that I need to compile for a c#/c++ interop
evaluation I'm doing.



But first, I simply need to compile some straightforward, non-managed,
console based c++ code. I created a win32 console c++ project. Then I
added several "existing" c++ .cpp and .h files. When I try to compile, I
get this error...



LIBCD.lib(crt0.obj) : error LNK2019: unresolved external symbol _main
referenced in function _mainCRTStartup

Debug/player-cpp-only.exe : fatal error LNK1120: 1 unresolved externals



My player-cpp-only.cpp file contains "main()". The error above leads me to
believe something is going wrong in or near the file containing main(), so I
have included the contents of that file below.



Recommendations for debugging will be greatly appreciated.



Thanks, Bruce



// player-cpp-only.cpp

#include "player.h"



namespace nsPlayer

{

int main()

{

Player player( "Test Player", false );

DiskCollection disks( "disks.dat", "Bruce's Disk Collection" );

player.attachAC(true);



return 0;

}



}
 
I suspect your namespace makes your main COMDAT something like...

?main@nsPlayer@@YAHXZ

....whereas _mainCRTStartup is looking for...

_main

....I bet if you take it out of the namespace it'll work, but if you still
have problems, you probably need to redeclare it as...

extern "C" int main()
 
Hi Bruce,

Do you have tried Jeff's suggestion?

Windowed applications on Win32 begin at WinMain() while character mode
applications begin at main(). Apparently you have mistakenly created a
Windowed project with console application code.

Hi,

I am getting the same error, but with an ATL-based COM project. As fa
as I know it doesn't have a main(). So what is going on? Any help woul
be appreciated.
