iEngine::Prepare() - segmentation fault

[brockmeister]

I'm attempting my first CS app, kind of following the tutorial on the main site. It works fine up until the point when I call iEngine::Prepare(). It goes like this:

Code:

csRef<iLight> light;
iLightList* ll = room->GetLights();

light = engine->CreateLight("light1", csVector3(-3, 5, 0), 10, csColor(1, 0, 0));
ll->Add(light);

std::cout << "Preparing engine...";
engine->Prepare();

'engine' is a csRef<iEngine>, grabbed out of the iObject registry.

I used the following plugin requests: CS_REQUEST_VFS, CS_REQUEST_OPENGL3D, CS_REQUEST_ENGINE, CS_REQUEST_IMAGELOADER, CS_REQUEST_LEVELLOADER, CS_REQUEST_END

This is the output I get:

Lightmaps are not up to date (no 'lm_precalc_info' found in cache).
Recalculation of lightmaps forced.
Initializing lighting (1 meshes).
Shining lights (1 lights).
Segmentation fault

I'm using Ubuntu Linux 5.04 (Hoary), with Crystal Space 0.98.

Can you run in gdb ( assuming you built Crystal Space in debug mode)?  This will give a better idea of exactly where the crash is happening.

Done - it says:

Program received signal SIGSEGV, Segmentation fault.

Hmm, casting shadows...can't really see what the problem could be.

Can you paste a bit more from the back trace?
