OSX: Custom resolution SegV

Post by milipili »

Hi !

On OS X, i tried to initialize the Irrlicht engine (The "Hello World" sample actually) like this :

Code: Select all

#ifdef _IRR_OSX_PLATFORM_
		createDevice( video::EDT_OPENGL, dimension2d<s32>(1344, 1008), 16,
			false, false, false, 0);
#else
...
I have got a nice exception error :)

GDB output :

Code: Select all

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000000

Any idea ?

I forgot to mention it works fine in fullscreen mode, and in a window mode with a resolution of 800x600 or 1024x768.

Looks like the video driver isn't initialized when OnResize is called. Maybe the Mac needs some cleanup of the event handling.
Please open a bug ticket at the SourceForge tracker, might take longer...

I asked to be notified when a reply is posted
and it seems the forum is aware of that ("Stop watching this topic" appears at the bottom of the page and the checkbox is checked).
I have checked my address email and that's ok.
However I did not receive any mail about the new post. Is it normal ?

Yes, sourceforge doesn't allow us to send emails from PHP otherwise spammers would use their service to send junk mail to everyone.

You can post a tracker item. If you login to SF before doing so you will automatically monitor the ticket, and see any progress mentioned there.

A similar problem happens to me, but just using my MacBook Air (which doesn't have a dedicated graphics card).

I previously posted a thread on the forum (http://irrlicht.sourceforge.net/phpBB2/ ... hp?t=30830), but after reading this post I've tried to play a bit with the resolutions.

I create the Irrlicht device using the following instruction:

Code: Select all

device = irr::createDevice(video::EDT_OPENGL, dimension2d<s32>(1024,768), 16, false, false, false, 0);
and it produces exactly the same error described in this post. Playing with the vertical resolution, I've seen that the application crashes only if this value is actually equal or bigger than 757...

There is no bounds checking when not in fullscreen mode

Post by hts13 »

The quick answer to the problem is that there is no bounds checking in the CIrrDeviceMacOSX::createWindow code [in CIrrDeviceMacOSX.mm]. When a window is created that would extend beneath the menubar and/or the dock the window creation fails. [v1.4.2]

Clipping the size of the winow before the window is allocated will fix the problem.

The tricky part is figuring out how much to clip. The display size is easy to get (it's already in there) but you need to subtract the height of the menubar and the dock. But the dock can move around so you have to know where the dock is before you can correctly clip the bounds.

Hopefully this will make it into the 1.5 MacOSX port. :)
