destroyImageSet causes crash :(

[RuprechtTheMonkeyBoy]

Woohoo! /me does the happy dance!

I have successfully built and used CEGUI on Mac OS X!!

As suggested, somewhere during the build, the Ogre memory manager was getting tangled up in the code, and the whole thing was getting botched up on String destruction.

I had to complete scrap the Xcode project and build a new one, carefully, from scratch. But it works great now!

@CrazyEddie:
I will have another patch to you this weekend for this work.

Whoo Hoo!

That's great news I'll look out for the patch.

Ok, I'm back to do some testing. ANd have recently built Ogre and plugins with debug stl (whoa, that was fun too) - so now I can debug
.

As a side note - is it just me that can't build/use debug GL rendersystem because glu.dll uses release stlport?

Anyway, after getting everything setup, and a quick test/debug run, showed the app to be indeed crashing during texture deletion. i'll look more into it and try the solution you posted first since I still havn't gotten to that.

I guess that would affect everyone the same

Hmmm. Hopefully the fix I checked in will have resolved that for you

Sinbad told me he has/uses the GL system in debug, so it must be something I did (or a vc6 hangup) - anyway, thats not important

I downloaded the most recent snapshot, and am a bit confused.

Code: Select all

void OgreTexture::setOgreTexture(Ogre::Texture& texture)
{
   freeOgreTexture();

   d_ogre_texture = &texture;
   d_width    = d_ogre_texture->getWidth();
   d_height = d_ogre_texture->getHeight();
   d_isLinked = true;
}


I see d_isLinked, but where is it used? I think it should of been added to:

Code: Select all

void OgreTexture::freeOgreTexture(void)
{
   if (d_ogre_texture)


But its not there, perhaps it should be:

if (d_ogre_texture = NULL && d_isLinked != true )

Ok, that fix made it work better... Instead of crashing on destroyImageSet the crash moved to destroy texture... So I figure destroying the imageset causes the texture to get deleted? Anyway, I removed my call to OgreRenderer-> destroy teture so I don't try and delete something that was already deleted.

And everything seems better now (except I think you should add that titbit of code I posted above), and now that I know CE deletes the texture from an imageset, I just will null it after that call. I will have an updated player demo that has several fixes shortly.

Thanks

I did have that exact code in as part of the fix, honest!

I think the reason it was missing is because I have two versions of the code I'm working on at the same time; obviously I didn't transfer the changes over completely. I'll get this sorted in a little while

I figured as much
