[IOS] 'irrlicht_main' instead of standard 'main'?

[galf]

Hi,

Environment: ios, xcode 6.2,ipad model: ME814HB/A , ios: 8.1.2

I ran the example code of ios and managed to make it work correctly.

now I want to create a device of irrlicht within my framework the same way I did in windows:

Code: Select all

 
irr::SIrrlichtCreationParameters params;
    
params.DriverType = irr::video::EDT_OGLES1;
params.WindowId   = view;
params.Bits       = 16;
params.Fullscreen = false;
params.Stencilbuffer = false;
params.Vsync = false;
    
irr::IrrlichtDevice* device = createDeviceEx((const irr::SIrrlichtCreationParameters)params);
 

but irrlicht's invokes linkedge problem : I haven't implemented irrlicht_main.
What I want to do is to run my own main and give irrlicht a handle to the view (like in windows).
so I did this :

Code: Select all

 
void irrlicht_main()
{
    NSLog(@"Not Suppose to enter here ");
}
 
int main(int argc, char * argv[])
{
    @autoreleasepool {
        int retVal = UIApplicationMain(argc, argv, nil, @"AppDelegate");
        return retVal;
    }
}
 

problems:

1) it did not solved my linkedge problem
2) I fear I'm doing something wrong. from the source code of irrlicht it seems that it's taking over all the ios app,
and in my implemetation i want that irrlicht will manage only one view. Is there a way To do what I want?

Thanks

At the moment there is a main() function inside Irrlicht for iOS so you can't have your own. Nadro and me have started discussing just this point last week. No solution yet (still under discussion...).

Thanks for the reply. I'm looking forward for this implementation...

About my linkedge problem:I found that If
I Implement my irrlicht_main() inside a .mm file (objective-c++ file)
it removes my linkedge problem (I guess my problem was the objective-c compiler).

Hi,

Please check an example no. 28. In the latest ogl-es branch you don't need own UIApplicationMain, UIApplicationDelegate etc. At now You can use Irrlicht on iOS like on the other systems, just replace 'int main()' by 'void irrlicht_main()'. In upcoming commits I'll add support for receive application delegate events like a applicationDidBecomeActive, applicationWillResignActive, applicationWillTerminate etc. via IEventReceiver. If you need custom UIApplicationDelegate you must wait a bit, I'll add support for this feature later.

Cheers,

I try to compile the helloWorld_IOS using xcode Version 7.2 (7C68)
just loading the BuildAllExamples.xcworkspace
and getting this error:

Code: Select all

I'll fix it tomorrow. Thanks for a report.

OSX examples has unnecessary entry and I'll remove it:

/Users/patryk/Programowanie/irrlicht-ogles/

however building works fine (I tested it on different Macs) for OSX example and iOS. Do you use a proper target?

I try to compile the helloWorld on Mac OS 10.11 using Xcode Version 8.0, but getting this error:
