Porting under QNX

[NoLJustS]

Hello. I have to test irrlicht under QNX. I've successfully compiled engine sources and then built couple of given examples. I've managed run them, but got next problem - GUIEnvironment returnes null from IrrlichtDevice in very first HelloWorld example(but not only there). Here is beggining of that code:
...
int main() {
IrrlichtDevice *device = createDevice( video::EDT_SOFTWARE, dimension2d<u32>(640, 480), 16, false, false, false, 0);
if (!device)
return 1;
device->setWindowCaption(L"Hello World! - Irrlicht Engine Demo");
IVideoDriver* driver = device->getVideoDriver();
ISceneManager* smgr = device->getSceneManager();
IGUIEnvironment* guienv = device->getGUIEnvironment();
...
}

I got null guinv here. Can somebody suppose what should i do, what should i check?

I'm rather surprised it even compiled. But I know pretty much nothing about QNX (except from what I can see on their homepage). If you are trying to port Irrlicht to a new platform you will have to be able to debug through such problems on your own.

Yeah, what kind of device do you use? Maybe it's just the console device?!

To all appearances I use SDL Device. I recently found that engine was compiled with commented line #define _IRR_COMPILE_WITH_GUI_
I think thats the point. I'm going to recompile irrlicht and test it again. I'll post here results.

So... I dont know why, but recompiling with _IRR_COMPILE_WITH_GUI_ did not help. But when i commented all the things in HelloWorld example which reffered to guiEnvironment I saw Sydney! I can say it surprised me that Sydney was drawn without drawAll() method of guiEnvironment, method drawAll() of scene manager was enuogh... I think its not last problem on my way, but its working under QNX, proved)

soo, the GUI is broken under QNX, but the scene manager is working?
Simple! Use an alternative User interface, maybe GTK+ or QT...
