CEGUI and Ogre Memory Manager

Robomaniac · Post by **Robomaniac** » Thu Dec 23, 2004 7:15 am

I'm currently working on implementing CEGUI into my game, but I'm having trouble with malloc errors. Apparently the cegui system uses a the xerces memory manager so i need to disable the ogre memory manager. At least this is what i've read. Is there a way around this? I don't want to lose ogre's functional memory manager (w/ the leak detection esp.)?

Thanks.

Put the CEGUI headers before any Ogre includes, or use the Ogre macros for disabling memory manager around the CEGUI includes - I forget what those are named, but they are include files.

From the top of my head, it should be something like:

Code: Select all

#include <OgreNoMemoryMacros.h>
#include <CEGUI.h>
#include <OgreMemoryMacros.h>

I had the same problem, but I didn't tested this solution yet.

Yeah, this is a conflict between Ogre and Xerces. I'll hopefully get this resolved shortly.

There is a separate issue, related to the debug memory manager, that also affects CEGUI/Ogre; this is caused by blocks of memory being allocated in the Ogre modules (under the memory manager) and later released within the CEGUI modules (without the memory manager) - you get an assert. This is more of an issue, and I'll be investigating possible solutions ASAP.

Alright, I'll try that.

This issue has now been resolved in CEGUI CVS-HEAD, so it is once again possible to use CEGUI with the Ogre debug memory manager enabled. I'll merge this, and another unrelated fix, into the 0.1.0 branch shortly.

I am getting an assertion failed window as soon as I quit Ogre (dbgheap.c, _CrtIsValidHeapPointer(pUserData)).

I am getting this exception in Debug mode and it occurs with all downloaded CEGUI Ogre demo's. I've downloaded the latest CEGUI version from the site (10/01/05). Everything else works fine (@CE, nice job btw).
