I have just installed VPython (and Python2.2) and tried to run one of
the demos. Each one results in the following error. I have Mesa
v3.4.2-7 installed. Can anyone tell me how I can fix this problem?

Presumably this is on Linux? Is there anyone among the VPython users that knows anything about Mesa? I gather it is supposed to be an alternative to OpenGL, but the overview at the Mesa web site implies that one should not expect it to work the same. Since the VPython Visual module interfaces to OpenGL, not Mesa, is there any reason to think that it should work with Mesa?

Eve... What version of gtkglarea do you have? I am using gtkglarea-1.2.1-1, you probably have something newer. Try downgrading to gtkglarea-1.2.1-1 and see what happens. (Unless downgrading breaks important dependencies that you need.)

I don't have a RedHat system, so packaging details could differ, but my
libgtkgl.so.5 doesn't have a glXUseXFont symbol anywhere in it. You might
have to run nm --dynamic on your various libraries in /usr/lib/*.so to
find out who (if anyone) defines that symbol. It may be that you simply
need another library added in to the link command.

It'll probably work on Mesa. I have gotten it to work somewhat with
Mesa, but frame refreshes are erratic. It's not clear if this is a
separate threading issue or a Mesa issue or what. I plan to try
re-installing with a 2.4.x kernel and see what I get.
The Mesa folks have traditionally been quite careful to respect SGI's
copyright and trademark claims on OpenGL, and to be quite clear that Mesa
is not an offical OpenGL product. I think that attitude comes through
clearly in the overviews and other documentation that comes with Mesa.
Sometimes too clearly, but they really do want to be careful and explicit
and not mislead anyone.
That said, they work very very hard to make it compatible with OpenGL, so
I'd expect it to work.

This is very odd, though. Others who have used the VPython installer for RedHat 7.2 (with gtkglarea-1.2.2-10.i385.rpm) have not reported a problem with this.

This sounds quite possible. Libraries often come in either run-time
versions of development versions. The development version is what's
needed to actually compile something, like Vpython.
Could you look and see if there's a RedHat mesa-dev package (or something
like that) that needs to be installed?

Hmm. On my Debian/Linux system, glXUseXFont is defined in /usr/lib/libGL.so,
which is provided by mesa.
Running
nm --dynamic /usr/lib/libGL.so | grep glXUseXFont
yields
0016b99c T Fake_glXUseXFont
001687d8 T glXUseXFont
What do you get?
My mesa-dev package identifies itself as mesag-dev version 3.4.2.1-4
(where the -4 is a debian-specific packaging indicator).
Hmm. I wonder if for some reason your mesa installation didn't
provide /usr/lib/libGL.so ? (Perhaps because the system was reserving
that name for a "true" OpenGL library?)

I do have /usr/lib/libGL.so.1 And the output of nm --dynamic /usr/lib/libGL.so.1 | grep glXUseXFont is: 001acb9c T DRI_glXUseXFont 001582f4 T Fake_glXUseXFont 001558d0 T glXUseXFont Sorry to be so lame, but what can I do about this now? I tried installing OpenGL but it conflicts with my current setup and I recall installing Mesa as a requirement for something else. -- ekotyk |
