How to detect if CEGUI was build with Xerces

[FluXy]

I need to detect if CEGUI was build with Xerces to set the xsd directory but the only method i found was with using

Code: Select all

#ifdef HAVE_CONFIG_H
#   include "config.h"
#endif


Is that the proper way

Because we also use a #ifdef HAVE_CONFIG_H in Secret Maryo Chronicles for Linux builds. I think that would conflict ?

I would say:

Code: Select all

#include <CEGUIDirectory/config.h>
#ifdef CEGUI_WITH_XERCES
    /* Blabla */
#endif


right now i'm on my windows machine where i compiled CEGUI using VS 2005 and that works. I think on linux that file will also be created, so no need for HAVE_CONFIG_H (I think). For mac, I don't know

#include <CEGUIDirectory/config.h>

I need it portable for Linux and Windows so everyone can compile the source without changing paths.

that's what i meant.
commonly, you already added the CEGUi include path to your include paths right ? You can simply include config.h, because AFAIK, it is created on windows too at least, it's the case for me

Yep but our game also seems to use a config.h on Linux.
So we would end up with 2 config.h files.

Problem is i have no Linux installed so i can't test if it would work.
Maybe we don't need our config.h include anymore so we can use the CEGUI one but the question remains if it's portable

eh didn't think of that ! but i think it sould work if, let's assume:
/usr/include/CEGUI is the cegui include dir.
/usr/include is in the incude path
so if in your code you do:

Code: Select all

#include <CEGUI/config.h>


Not sure if that works, I didn't test it, but it should, as long as you don't have a directory named CEGUI in your game's directory. And i am not sure anymore if "make install" also copies the config.h file into /usr/include/CEGUI, but IIRC it does.

Hope that helps

Thanks for your help Pompei2

nyhm our Gentoo Maintainer told me CEGUI doesn't install its config.h so we do now have the xsd files at both locations ( application and gui data directories )


I think the best way to find out at compilation what compiler is used should be over CEGUIconfig.h and not config.h.
The defines should be there

Is this a bug or feature request

Why not try to load it and check for exception if not available ?
