[Visualpython-users] VPython compile problems - Mandrake 8.1

[rod h. <rh...@St...>]

To list:

I will start with a general explanation and provide more details later if
needed.

1. I am compiling on Mandrake 8.1
2. Python 2.2, Idle-Fork, and Numeric are installed and functioning
3. Two problems arise with installing VPython
	a. the gtkglarea.rpm installation process (from the install script) says
it is already installed and then spits out a long list of database 	errors
- then the script continues to compilation of cvisual.
	b. the compilation of cvisual always ends in a seg fault - usually in
vthread.h.

What I have tried so far-
1) using the gtkglarea libs from the Mandrake disks and commenting out the
rpm process from the install script.
2) commenting out the offending lines in the include files that generate
seg faults

Neither work.  Are there any suggestions?

Thanks,

Rod

I have also had this problem.  I can't offer a solution, but I can add
that using the gtkglarea rpm from red-carpet (ximian) does not work,
either.  Tried uninstalling w/ red-carpet to allow the install script to
do its thing, also to no avail.  Rpm database seems to be intact, as I
tried --rebuilddb and met same end result.

You've probably seen this note ("additional info" on the Linux download 
page), but just in case you missed it, here's a comment on getting VPython 
to work on Debian.

The VPython installation procedure should work on most versions of Red Hat
   Linux, and it may work in other Linux environments as well. If not, Andy 
Dougherty
   offers the following useful information.

Other packages you may need are commonly, but not universally, installed on
   many Linux systems. I can tell you that on my Debian system, I also 
needed to
   add glib, gtk+, and some sort of OpenGL library. You may need to check that
   you have the development versions of the libraries. [1]

VPython includes gtkglarea, but if you can't use the supplied i386 rpm [2]
   you may also need to install gtkglarea from source. If so, I'd recommend 
using
   the slightly-newer gtkglarea-1.2.3 -- it worked marginally better for me.

Where you get OpenGL may depend, in part, on which X server you're using. I'm
   currently trying Mesa as an OpenGL replacement, but with mixed success. The
   Visual window only seems to be updated occasionally; with the same 
program under
   Windows, the updating is nearly continuous. Hope this helps,

[1] For some libraries, some Linux distributions sometimes ship both runtime
   and development versions. You need the development version if you want 
to compile.

[2] e.g. if you don't have an rpm command, or if if you're running on a 
different
   architecture, such as an Alpha or SPARC.

Here, I can't help, since I'm unfamiliar with rpm packages and the
associated errors.

Could you send more specific info -- perhaps the last few lines of a build
log?

What are the offending lines?  What process is segfaulting -- is it
Python, gcc, ld, ... ?
