Trouble compiling my Ogre app with CEGUI

[Walley]

In my Ogre application, I'm merely including "CEGUI.h" and "ogrerender.h" from CEGUI at the moment, as well as using one function (which is not the source of the problem).
I was able to get this compiling and running fine in Release mode with the latest stable release, but in Debug mode I got assertions etc :\.

I'm now using the latest version of CEGUI from CVS, as I was told the assertion problems were fixed with it. However, it generates numerous errors (show in the build log below).

I searched through the forums, and tried a number of the relevant suggestions - I currently have Ogre Debug compiled without the debug scene manager, and have also made sure that "CEGUI.h" (and "ogrerender.h") is included before "Ogre.h" is anywhere.


Any help would be appreciated.

The build log is as follows:

Ok, I managed to get around that by using #undef max and #undef min.
However, now when I compile I get the same problem I was getting with the previous CEGUI and Ogre - in Debug Mode I get ms_Singleton Assertion failed upon calling
CEGUI::Renderer* renderer = CEGUI::System::getSingleton().getRenderer();
however, in Release mode there is no such problem :\
As mentioned above, I've compiled Ogre Debug with the debug memory manager disabled :\

[CrazyEddie]

Since release mode is working, the 'obvious' question of whether you're instantiating CEGUI::System is answered So, I think I'll have to look into this a little - though I have not seen this issue here.

Is there anything (errors) in the CEGUI.log file?

[Walley]

In my additional ignorance I also forgot to log in 8O.

Anyways, is CEGUI set to generate a log by default?
As it's not :\

I tried 'Logger::getSingleton().setLoggingLevel(Informative);' (saw that in one of the demos), but even it generates an assertion so I can't get a log ^.^.

[CrazyEddie]

Yes, a log is always generated once the base system is up and running. In this case it seems that none of the core library singletons are being created. What happens when you trace into the contructor for the System object? Are the lines:

Code: Select all

   // cause creation of other singleton objects
   new ImagesetManager();
   new FontManager();
   new WindowFactoryManager();
   new WindowManager();
   new SchemeManager();
   new MouseCursor();


being executed?

CE.

[Walley]

How embarassing - I think the problem was that I was never calling:

Code: Select all

mGUIRenderer = new CEGUI::OgreRenderer(mWindow, Ogre::RENDER_QUEUE_OVERLAY, false, 3000);
   new CEGUI::System(mGUIRenderer);

And initializing the system :\
The fact it worked (?!) in Release mode made me think that what I was currently doing was fine :\

Lol ^.^

Oh well, I'll learn from that mistake :\

In case I'm mistaken I'll put CEGUI back into my project and see how it goes.

PS. It'd be cool if I could like... erase this post from everyone's memory

Hehe no one is immune from making silly mistakes from time to time.

[CrazyEddie]

These things do happen to the best of us. I have a very long list of silly things I've done before; all things that once the mistake is known, I can't believe that I did it in the first place

I am having this exact problem with

c:\Program Files\Microsoft Visual Studio .NET\Vc7\include\malloc.h(113) : error C2143: syntax error : missing ';' before '.'

occuring, I get about 17 of these.

where do you do the #undef min and #undef max to get this problem to resolve? I tried adding them but couldn't seem to get it to compile still.

thanks much

[CrazyEddie]

the #undef directives for min/max go after any Win32/DirectX include, so group all those together and just do the undefs once afterwards.

I'm not certain if this is your problem though; I'd be more inclined to guess it's an issue with memory managers. If it does turn out to be the memory manager issue, you must either ensure that the CEGUI includes appear before Ogre includes (and the include for the Ogre GUI renderer), or surround your CEGUI includes with includes of the OgreNoMemoryMacros.h / OgreMemoryMacros.h files. Just to reiterate an important point here - the OgreRenderer.h should also appear after all other CEGUI includes as it includes Ogre.h.

HTH

CE.

[paddy]

Wow you got it. I'd never guess a syntax error in malloc would be due to the order of headers, but that fixed it perfectly.


Thanks again
