First of all say HI!!! :)
This is a question that makes me feel stupid since it is one of those asked trillion times and answered trillion times, but I failed to find that answer in the forums with the search tool above.
I'm using code::blocks with MSVC2003 toolkit and MSDK. To be sure all would work fine from start I followed the MSVC toolkit integration tutorial to set up lib and include paths properly.
I tested the settings with a simple console project (yes, default compiler MSVC2003) and no problems compiling neither linking.
When I replaced the "main" identifier with "winmain" the problem shown up:
"error LNK2019: unresolved external symbol _WinMain@16 referenced in function _WinMainCRTStartup"
it's clear that it is a missing library, but can't figure out which one since the MSDK libraries paths are all correct (checked like 10 times).
Any help would be welcome and I beg your pardon if there's already a post about this issue elsewhere in the forums.
Thx in advance :)

Ok what version of C::B RC2, SVN-HEAD? Could you post some code and the libs you are linking in? You did include windows.h right... :lol:
EDIT:
There is a template for Windows GUI programs too. :wink:
-
You need to change the "subsystem".
Menu Project->Properties->Targets tab.
In Select build target options->Type: change from "Console application" to "GUI application".
But anyways, I wonder why you want to use WinMain as the entry point. Are you programming with MFC?

Uhh WinMain is for Win32 API programming....... Not MFC (AFAIK)......

It is used, but internally, AFAIK.

Ah I see.

AFAIK WinMain (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/windowing/windows/windowreference/windowfunctions/winmain.asp) is used by Win32 API (independent of using MFC or not). Win32 API is a C API. MFC (http://en.wikipedia.org/wiki/Microsoft_Foundation_Classes) wraps portions of the Windows API in C++ classes. Normal C/C++ programs use main, but windows programs use WinMain.

[EDIT] A link about the Windows API (http://en.wikipedia.org/wiki/Windows_API) for all the fans of Windows :D.

Thx for the tips :)
I forgot about the templates... guess I was too tired when I posted the issue.
The problem was a bad declaration of winmain. Guess I've been using BCB for too long and I forgot the basics :lol: :lol: :lol: :lol:
I must ask you for your forgiveness to take room in this forum for such stupid question :(
Thx again for your help.
