SDL-OpenGL Texture mapping

SDL Development
1

Gidday,

I’ve been trying my hand at OpenGL texture mapping, and went back to a
tutorial I had looked at some time ago, located here:
http://nehe.gamedev.net/data/lessons/linuxsdl/lesson07.tar.gz

Pretty simple, a texture-mapped spinning crate.

Now, this demo has worked fine for me in the past (I’m talking 1-2 years
ago), but when I fired it up today on my Red Hat 9 machine
(SDL-1.2.5-3), no textures were loaded, all the surfaces are white (or
the colour of the light source if I enable lighting). All the files are
still there. I even downloaded lesson6 (a simpler texture mapping demo)
with the same results.

The Linux/GLX version works fine, just the SDL version doesn’t.

Does anyone know if these NeHe tutorials contain deprecated SDL code, or
am I doing something wrong?

thanks,
Greg

Hrmmm… I assume you’re trying to compile/run the code unmoddified, so you
can tehoretically blame the the SDL port from NeHe’s tut7.
I believe it worked fine last time I downloaded it – of course I’m on
Windows, so that might affect it. Re-check the code to make sure you’re
trying to load the correct files (with the right case, too). If all else
fails, try contacting NeHe – he seems to respond to most emails within a
day or two (tip: if you try to send around 1 to 2 am [EST], he might respond
within an hour or two [experience])
