ConvexShape/TriangleMeshShape crash in Linux NxOgre 0.9

Hello all,


I seem to be unable to load any TriangleMeshShape nor ConvexShape. I tried the easiest possible test, that is, adding the following line to the (previously functioning) Cake:

mScene->createBody("testcyl.mesh", new ConvexShape("testcyl.mesh"), Vector3(6,2.5f,0), "mass: 10");
or also
mScene->createBody("testcyl.mesh", new TriangleMeshShape("testcyl.mesh"), Vector3(6,2.5f,0), "static: yes");


No matter what I try, I always get a core dump with the following backtrace:

Mesh: Loading testcyl.mesh.

Has anyone ever been able to use a convex or trianglemesh shape in nxogre under linux?


I've got the following environment:

NxOgre (NxOgre 0.9-38.Debug) Started, working with:

- PhysX => 2.7.2
- Ogre => 1.4.3 'Eihort'
- Platform => Linux Debug


Thanks in advance for your input..

Yep; Looks like a Cooking issue or the stream it is writing too. Have you tried Bleeding under linux? The cooking process has greatly improved.

No I haven't ever even "checked out" bleeding, but I will now

I just hope there are no huge changes from 0.9-38 to bleeding, as I just finished converting an old 0.4-RC3 app to 0.9 with more than a few headaches and hacks (I'll have to rewrite the 0.4 app from scratch with 0.9 or possibly the future 1.0)


Btw, talking about cooking, I remember/think it wasn't possible to cook from file in Linux with the 2.6/2.7(.2?) PhysX SDKs, do you know perhaps if it is possible now?

Thanks

Sadly (for you), there has been big changes. So you will have to update your application again.

I honestly don't know if you can or can't cook in Linux. I don't run the operating system on my computers so I've never tried. If it was true however, I would expect to hear more posts about it.

Ouch... bad news for me then


Anyway, as I was trying to compile bleeding, I immediately got the following error (which I'm investigating with my scarce c++ template knowledge):

I'll try solving that, while waiting for other Linux users to tell me their Convex/TriangleMesh shapes stories

I have a copy of the latest Beta of Ubuntu which I believe will install itself as a file on one of my partitions. If I dare to install it, I'll try and make BetajaenCC GCC compatible.

Oh, I knew you're always willing to help, but this would be truly great

Anyway, and I'm not in a haste, and I believe/hope I'm not the only one using Linux and complex shapes out here

Thanks for your support
