[Mac OS X 10.4] Problems with CEGUI and samples....

For help with anything that CEGUI doesn't offer straight out-of-the-box, e.g.:
- Implementation of new features, such as new Core classes, widgets, WindowRenderers, etc. ...
- Modification of any existing features for specific purposes
- Integration of CEGUI in new engines or frameworks and writing of new plugins (Renderer, Parser, ...) or modules

[Mac OS X 10.4] Problems with CEGUI and samples....

Postby Alexco » Wed Sep 28, 2005 13:05

Hi!

I am currently trying to compile CEGUI on OS X Tiger using XCode 2.1 (GCC 4.0). After some problems I got it compiled using TinyXML. But I run into deep trouble when trying to compile the demo4 sample.

1) some include statements are wrong e.g. <GL/GLUT.H>, but this was no problem.

2) the example application code checks for Win32 and for Linux and allocates a CEGuiRendererSelector accordingly. But there is no default if the system is not Win32 or Linux. I changed that to the CLICEGuiRendererSelector.

Now the sample code compiles as a BSD shell tool project (Is this OK?).
When I start the demo4 executable I can select the OpenGL Renderer. After that the application segfaults with signal 11 (SIGSEGV).
When started in the debugger I can see that the problem is located in the CEGUIString class inside the grow() method:

CEGUIString.cpp
line 64:
utf32* temp = new utf32[new_size];

This is called from
Sample_Demo4.ccp
line 58:
SchemeManager::getSingleton().loadScheme("../datafiles/schemes/TaharezLook.scheme");

The Thread Display from the GDB looks like this:
#0 0x90003b94 in szone_malloc
#1 0x900039fc in malloc_zone_malloc
#2 0x90003954 in malloc

#17 0x0102ec30 in CEGUI::SchemeManager::loadScheme
#18 0x000034d8 in Demo4Sample::initialiseSample at Sample_Demo4.cpp:58


Anyone with a working CEGUI.framework and samples here who can help me?

regards,
Alex
