My compiler is currently returning the following:
error LNK2001: unresolved external symbol __cedcl main(int, char**)

As its only error in Release. It appears to be having an issue with the SDL entry point main.
I have linked all necessary libraries and my runtime is set to /MD.

I receive no errors in debug and fail to understand what could be causing this error.

Thanks a bunch, GDN.

Did you set the Subsystem to /Windows in the Debug configuration but forget to set it in the Release configuration?

Nope, the subsystem is windows.

Are you linking in SDLmain.lib?

Are you linking in SDLmain.lib?

Yeah. I'm really stumped as to what the issue is.

Can you paste the linker command line? I believe it is available somewhere in the Visual Studio linker settings. Consider investigating any differences between your Release and Debug linker command line as possible sources for this error.

Try changing your int main() or whatever you have to:

int main( int argc, char* args[] )

That should fix it. If not let me know.

<br>Your release settings contains an explicit entry point, but your debug does not. A quick glance at the SDL documentation suggests to me that SDL provides the actual entry point as WinMain and "overloads" your own main function. Remove the entry point setting, unless there's a reason you've defined another entry point of course.<br>[/quote]<br><br>Thanks, that worked. I think I set that entry point because of advice I read elsewhere on the internet. Thankyou very much!
