Segmentation faults on Linux - vicovermeer - 05-02-2008
Hi!
First of all sorry for the long post. But I tried to give you as much information as possible from the very beginning.
I get at least two segmentation faults when I run vdrift. I use Linux openSuse 10.2, 32bit, have a GeForce FX 5500 (with the latest nvidea driver installed, 3d acceleration turned on). The compiler is gcc (GCC) 4.1.2 20061115 (prerelease) (SUSE Linux).
What happens?
1.
The call
Code:
program = glCreateProgramObjectARB();causes a segmentation fault.
Code:
0x00000000 in ?? ()
(gdb) up
#1 0x0811b536 in SHADER::Load (this=0x82d0ce4, name=@0xbfbe95d8) at src/shader.cpp:25
/home/ssager/solver/vdrift/src/shader.cpp:25:588:beg:0x811b536Code:
shaders = offin .vdrift/VDrift.config
I get a little further. Now the segfault is caused by
Code:
collisionbroadphase = new btAxisSweep3(worldAabbMin,worldAabbMax);in PHYSICS::Init (this=0x8261394) at src/physics.cpp:17
Code:

Thanks for any help on this,

Problem resolved - vicovermeer - 05-02-2008
Hi!
I finally resolved the problem. I had bullet version 2.68 installed (via Yast), obviously VDrift does not like this version. Building the bullet 2.66 sources supplied with VDrift everything works fine now.
Except for the shaders problem. I still have to set shaders=off, otherwise I get the segmentation fault described above.
Thanks,
Sebastian

Hey, you might want to check that your card supports shaders. I don't really know much about the FX5500s, I have a FX5200 that doesn't really do well with VDrift at all. It will run but I believe I had to turn shaders off as well.
- joevenzon - 05-05-2008
The geforce 5XXX series cards only support simple shaders (equivalent to directX PS2, I think), which apparently VDrift's aren't. You could try turning off shadows; that might make the shaders compatible with your card... but I'm not sure.
