Leaks in Irrlicht?

[RageD]

Hello,

I was wondering if there are any known leaks in Irrlicht. I am writing a small library for use with Irrlicht, and I went to check it for leaks and (after running it through valgrind) received this response:

Code: Select all

ERROR SUMMARY: 3 errors from 3 contexts

The errors seem to all come from Irrlicht's createDevice() as an origin. I know my other code isn't leaking because I ran it through the debugger without Irrlicht.

In any case, I am more concerned that I am doing something improperly if Irrlicht has no leaks. In the constructor of one of my classes, I initialize a private member (of type irr::IrrlichtDevice*) doing this:

Code: Select all

device = createDevice(...);

Then, in the destructor, I have this:

Code: Select all

if(device)
        device->drop();

Am I missing something? This is all the Irrlicht code I am currently using (i.e. I have not begun using any other objects). I do, however, call device->getVideoDriver() for beginScene() and endScene() (if this would cause any leaks since I have not assigned it to any member, nor have I dropped it).

Thanks for your help. I am also using the OpenGL drivers.

I suspect you are using valgrind? Doesn't that give you where the leaks are? Anyway - we use that ourselves regularly and at least here the first example does not leak (others also shouldn't, but haven't run them right now).

I have 3 leaks also, but I don't think it is irrlicht causing them. I used valgrind and it showed me that it leaks somewhere in the video drivers (nvidia).

Ah, thanks guys - serengeor is right; it's the video drivers. I didn't read far enough up, my apologies.

Seems to be a problem with OpenGL which, on most systems, would probably be out of my control.

Thanks!
