Windows problems with SDL/COM

SDL Development
1

Hello,
I’m just starting out on SDL (from Allegro).

Everything is going fine and apps. are being generated ok (i.e. my setup and
project settings are fine), but my problem is this: I’m creating a Windows
COM library for using SDL via VB, etc (using the COM ATL) (I’m using the
correct multi-threaded run-time library), but get the following errors.

MSVCRT.lib(MSVCRT.dll) : error LNK2005: XXX already defined in StdAfx.obj

  • Where XXX is _free, _malloc, _realloc,

Anyone any idea how to get rid of them. I’m assuming that SDL has already
defined these functions but STDAFX has also.

I also had to remove the ‘#define main SDL_main’ (in SDL_Main.h) which I
assume is ok as COM uses its own main.

Thanks.

Perhaps try adding msvcrt.lib to the Ignored libraries list in MSVC. You
should find it on the Link tab in the Project options I think, or use
MSDN to find out how to do this if you’re using makefiles.–
