Linux no meshes in samples CVS

MadLion · Post by **MadLion** » Tue Jan 18, 2005 8:57 pm

Hi,

i'm using linux and the last CVS.
If i run the sample apps e.g. CameraTrack or Shadows. I didn't see any meshes (e.g. ogrehead.mesh).
See CameraTrack here or Shadows here.

Any ideas?

It works OK here. Can you paste your ogre.log?

I also checked it on another machine (notebook) with same results.

Both machines running Fedora Core 3. One machine with ATI radeon 9600XT and the other nvidia gforce 4, i think.

Post by **:wumpus:** » Wed Jan 19, 2005 10:46 am

I still cannot reproduce this; I'll try with the new ATI drivers in a minute.

Post by **:wumpus:** » Wed Jan 19, 2005 1:17 pm

For some reason it can't even make a GL vertex buffer anymore now that I've installed those new drivers and recompiled. What a fun.

MadLion · Post by **MadLion** » Wed Jan 19, 2005 1:25 pm

That's strange... but why doesn't it work for nvidia too?

If i'm back home in same hours i will try Ogre 0.15.2.

Post by **:wumpus:** » Wed Jan 19, 2005 1:32 pm

Turned out to be a gentoo problem; it was linking against the x11 GL instead of the ATI one. All problems appear to be solved now. I don't understand where your problem is coming from.

MadLion · Post by **MadLion** » Wed Jan 19, 2005 1:50 pm

Hm... i think i have installed freeglut-2.2.0-14.i386.rpm. Maybe it's the problem?

Post by **:wumpus:** » Wed Jan 19, 2005 4:42 pm

The glut version doesn't matter for OGRE, it doesn't use that
Can you paste the output of glxinfo?

And I see you're using SDL; please try also with the GLX system (--with-gl-support=GLX --with-platform=GLX)

Yes i did this too with same results on both machines (notebook and desktop pc).

I was testing Ogre 0.15.2 and there it works.

What is the different?

MadLion · Post by **MadLion** » Fri Jan 21, 2005 4:46 pm

No ideas on this?

Post by **:wumpus:** » Fri Jan 21, 2005 4:55 pm

It is still the case with latest CVS?

Very very weird, I have no idea really as it happens both on a NV and an ATI card so it can be no driver sissue. It works ok on all my machines though.

With CVS of yesterday, yes.

I agree very very weird. The only think both have same is the linux OS fedora core 3.
I'm confused.

What's your gcc version?

I think gcc 3.4.2 but i'm not sure as i'm not at home to check exactly.

That's the only reason I can think of that our results differ. But it still makes little sense afaik there are more people using gcc 3.4.x with ogre.

I got something similar on the AMD64 port before I sorted out the serializer issues, but it works fine at the moment.

*reads "migrating gentoo to gcc 3.4"*

I tried using both g++ 3.3,5 & 3.4.4 (on AMD64) and both worked fine for me. I'm only able to try this on my NVidia card atm

AMD XP3000 32 bit here, upgraded to 3.4.3, linked to ati GL drivers and I have the problem too. The world is empty and meshless, At least I can reproduce it now.

Manually defined meshes seem to work great ,but ones loaded from .mesh format don't. I also get the AnimationState exception in some demos.

Sounds like a serializer issue. The only changes to the serializer in HEAD over 0.15.2 are the AMD64 compatibility, and they work fine everywhere else - perhaps try rolling back the serializer until you don't get the problem anymore to figure it out?

Weird that there are no issues on other versions of gcc though. Might be worth trying gcc 3.4.4 incase it's a gcc bug, I hear there were major changes in gcc 3.4 over 3.3 which perhaps weren't all solved in earlier point releases?

It wasn't a gcc bug or a MeshSerializer one; the DataStream::skip was misdefined to take a size_t although it should be a signed size (ssize_t). MeshSerializer makes extensive use of this to skip back into the stream.

Anyway, this is solved in latest CVS

Great news! ^^
Now i have to wait for the anonymous CVS update.

Big thanks so far!
