Unresolved External Symbol

Here's a good one for you all. I'm making a very (VERY) simple Win32 application that is supposed to display a message box. And it won't. I know good and well that <windows.h> is the header to use when using MessageBox(), so I'm getting REALLY confused.

Code:

#include <windows.h>

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
	MessageBox(NULL, "Test", "Test", MB_OK);

    return(0);
}

Yes, the linker is set /SUBSYSTEM:WINDOWS. I checked that one already. The error is:

main.obj : error LNK2019: unresolved external symbol __imp__MessageBoxA@16 referenced in function _WinMain@16

Help?

that's odd - what compiler are you using?

Visual Studio 2005 Beta WITH the Core SDK installed and referenced in the compiler.

you might try re-installing it - it appears the linker is confused.

Reinstalling didn't work - but.

It appears that the Core SDK is moronic and the "Register PSDK Directories with Visual Studio" command does not work. YAY.

*tries something*

Nope. Even telling the compiler manually that the includes are at X and libs are at Y didn't work. Hello complete loss of ideas.

Get a different compiler?

Ok.. what is your suggestion for a Visual Studio 6-like IDE using compiler that's more standards-compliant than Visual Studio 6?

Well I personally love Dev-C++ because its free and its awesome . If you want a sorta vc++ fell you could go for minGW developer studio.

Ok, so we'll try Dev-C++. Why not, right?

MessageBox() is in user32.lib so you have to link with it.
If it still doesn't work make sure the search path for libraries includes the directory that contains user32.lib.

gg

I had done that, actually, according to Microsoft's instructions (How to use the SDK with Visual Express 2005 Beta). *shrugs*

Using Dev-C++ now. Thank you for all the help, though!

checked it with Dev-C++ and it works perfect
