Little problem with compiling Qt4 app (Ambigious symbol)
-
@1>.\GeneratedFiles\Debug\moc_cirrationalengine.cpp(20) : error C2872: 'uint' : ambiguous symbol

seems to be ok.......then again i'm no expert on a lot of things about C++ :-p
So how to get rid of that? seems like i might have to do something or what not. Hmmm -
You can remove
@
using namespace Ogre
@It should help.

@static const uint qt_meta_data_CIrrationalEngine[] = {

@the problem comes frm this file, i removed the using namespace Ogre......so idk, let me know if u need something else, the material editor is important although not so important that i can stop dev of the engine.
-
so removing using didn't help? can you provide current output of compiler and text of file where this error happens (or at least all includes and usings from this file and some code around error string)?

like i said, i don't know if that will do let me know if u need anything else, I'm in no rush (I got Ogre to render in a Qt4 widget, took a couple days and a lot of trial and error) -
You still didn't answer if you removed @using namespace Ogre@ or not?
-
Does cirrationalengine.h contain using instruction too? If yes try to remove it from there.
-
Both Qt and Ogre typedef uint. Fortunately, Ogre uses a namespace so you just need to remove all of the "using namespace Ogre;" statements from your source code. Then, you will have to prepend all the Ogre types with Ogre:: (so String becomes Ogre::String, FrameListener becomes Ogre::FrameListener, and so on).
Also, I don't know if you are using your own FrameListener or the one that comes with Ogre (ExampleFrameListener) but the example one had the "using namespace Ogre;" statement in it so you'd have to either implement your own FrameListener or modify ExampleFrameListener.h as well.

yea, i figured that out, thanks, one thing i've noticed i was creating the material editor window and got a few access violations, also, seems like when u open the editor and close it and open it again, that gives a "window already exists" exception from Ogre, there has to be a way to make it so when the window is closed it destroys the RenderWindow then when the editpr window is reopened recreates it......Hmmm
