Example Run problems on Linux

zip · Post by **zip** » Mon Jun 27, 2005 10:04 pm

When I try to run any of the examples that load data files they fail to load, due to unreadable headers or unrecognized file format.
Example03 for example runs fine since it does not load any models/textures.

Here is the result when I try to run Example1

Code: Select all

zip@tartarus:~/Desktop/irrlicht-0.10.0/examples/01.HelloWorld$ ./example
Irrlicht Engine version 0.10.0
Linux
Creating X window...
OpenGL Renderer.
OpenGL driver version is 1.2 or better.
Multittexturing active.
Not a PNG file: wrong header
: #DefaultFont
Could not load texture: #DefaultFont
Error: Could not load built-in Font.
MD2 Loader: Wrong file header: ../../media/sydney.md2
Could not load mesh, file format seems to be unsupported: ../../media/sydney.md2

I've never used any 3d on linux, but maybe you can't use md2 on linux. perhaps it is a "windows only" format.

But then again, I don't really know.

MD2 is the Quake 2 model format, it is widely used on multiple platforms.

What system architecture are you using? Irrlicht does not support big endian systems right now, it could be a problem related to that topic, or related.

What system architecture are you using? Irrlicht does not support big endian systems right now, it could be a problem related to that topic, or some compiler/linker problem. Did you get any warnings?

are you sure you have rights on those files ? if not try to do a chmod 755 on them

I'm using Irrlicht with linux, and all examples works well

Check whether the files are actually in
~/Desktop/irrlicht-0.10.0/media

(~ is your home directory)

I don't know about that default font. If it's supposed to be built-in, I don't know what a PNG loader has to do with it.

Oh sorry. I thought Q2 was a windows only game...

Nexus: It isn't, but it wouldn't matter since the code to load MD2s is built into Irrlicht.
I have already checked permissions and that the file is indeed where it should be("Unsupported file format", not "File not found").
I'm running a PPC which is big endian so... short of buying a PC, what can I do?

I see. Thanks for explaining that.

I'm still new to this. lol.

Change Irrlicht to support big endian?

Yes, most file loaders (image and mesh) need byte swap functions to be built in. I have a first rip off patch from IrrlichtNX, but I never tried to apply it yet. If someone wants to try I could send it on request. Be aware of much work todo, though.
