How to debug irrlicht.dll?

pera · Post by **pera** » Thu Jul 15, 2010 8:27 pm

I have a nasty crash that I can not resolve.

debugging throws error in crtexe.c function __tmainCRTStartup

First-chance exception at 0xfeeefeee in GameExample.exe: 0xC0000005: Access violation reading location 0xfeeefeee.

callstack indicated some irrlicht.dll functions has been called.

Crash happens when player kills the monster, and the node is deleted.
I suppose someone tries to use the node after that, but not directly from my code. Maybe some collision animator or something like that.

So how do I debug irrlicht.dll, do I have to build it from source? Can it be done in VS2010?

Thanks.

Yes, you have to build it from source selecting the debug build. Usually it's easy as all you have to do is opening the project file and just compile it. But we have not VS2010 project file so far, maybe importing the older project files will work, but I haven't found time yet to test it myself.

I don't see download link on that german page, and i tried downloading several direct sdks, but something is always missing. Which one is good one? Tutorial page for irrlicht compiling has broken links. If anyone can point me to lib and header zip that would be nifty.

there is the link on the left side, right below the downloads count...
it says "GRATIS DOWNLOAD" and below that is a link to "Server 1"...

ATM I'm not sure if DX8 is included to that sdk, but I think so...
anyways it's probably a good idea to disable DX8 in Irrlicht as it's obsolete if you have DX9...

And success!

debug irrlicht.dll lead me to exact spot of my big bad crash.

IAnimatedSceneNode.cpp:
LoopCallBack->OnAnimationEnd(this);

called on removed node.

Thanks everyone.

when I use irrlicht debug dll (1.6) I get memory leak in visual studio on close.

when I use release irrlicht, no.

does that mean memory leak is in irrlicht code?

We don't know about memory-leak, although that certainly doesn't mean we have none. But without code to reproduce it we can't tell.

I think you will get a memory-leak if you close the console window instead of the application window so maybe you did that?

No. But since its 1.6 I think it doesn't matter anymore.
I'll check it once again when I move to latest irrlicht version.
And I can try with hello world example when I get home.
