Linking error?

When I compile my program, it compiles without an error. When I try to build it into an EXE, this is the error I keep getting. Any ideas on what this may be from?

Code:

--------------------Configuration: main - Win32 Release--------------------
Linking...
main.obj : error LNK2001: unresolved external symbol _listen@8
main.obj : error LNK2001: unresolved external symbol _closesocket@4
main.obj : error LNK2001: unresolved external symbol _bind@12
main.obj : error LNK2001: unresolved external symbol _socket@12
main.obj : error LNK2001: unresolved external symbol _htons@4
main.obj : error LNK2001: unresolved external symbol _gethostbyname@4
main.obj : error LNK2001: unresolved external symbol _gethostname@8
main.obj : error LNK2001: unresolved external symbol _send@16
main.obj : error LNK2001: unresolved external symbol _recv@16
main.obj : error LNK2001: unresolved external symbol _accept@12
Release/main.exe : fatal error LNK1120: 10 unresolved externals
Error executing link.exe.

main.exe - 11 error(s), 0 warning(s)

When a compiler generates such errors it's (very often) because it doesn't recognise the used commands/variables/ops/function calls . In your case, the unrecognized are: _listen@8 _closesocket@4 and so on... (you get it).. those function calls are surely, like SilentRage said, defined in the wsock32.lib ..... Yep... that's why. Hope you got some light into it,,, _________________________ - "It's not my code that's useless it's you loosers being unable to apprecitate it because of your lack of skills!" /zenon - C++ master Apprentice

Just in case you don't need IMP files with every non-template header, I didn't know. I'm fairly new to C++.
