[Visualpython-users] RedHat 7.1 libgcc_s.so.1 and libstdc++.so.3

[Kevin C. <kj...@gr...>]

Hi,

I just grabbed the latest VisualPython RPM (20010828-3), but it fails
with dependencies for:

   libgcc_s.so.1
   libstdc++.so.3

Anyone know where to find RPM's containing these?  (I think I saw a
Mandrake RPM for one of them, but I'd rather get something that was
built on/around a true RedHat 7.1 if possible.)

Weren't the Apple people supposed to be working on a (presumably Cocoa) OSX
version of VPython? Did that get anywhere?

[Visualpython-users] VPython on Mac

[Bruce S. <ba...@an...>]

I think I may understand the issue with installing and using VPython on the 
Mac, based on Python 2.1.1.

For Macs running OS 9.0 or older, the existing installation and use 
instructions work.

For later versions of the OS, you have to run the program 
"ConfigurePythonClassic " to configure things properly for VPython to work.

We'll update the instructions to reflect this.

[Visualpython-users] Mac installation

[Bruce S. <ba...@an...>]

A user had difficulty getting VPython to run on a Mac until she ran 
"ConfigurePythonClassic". I had no idea that this would do anything, but I 
record the event here.

Re: [Visualpython-users] which file to associate .py files with?

[Matthew K. <koh...@an...>]

Joe,

When you open "Folder Options", click on the "File Types" tab, and then 
double click Python files (.py) in the list of file associations. It will 
bring up an "Edit file type" dialog box.  Under "Actions", select "open", 
then click the edit button. Then, in the field called "Application used to 
perform action", paste the following:

C:\Python21\pythonw.exe C:\Python21\Tools\idle_VPython\idle.pyw "%1" %*

This gives the behavior you want.  I also made a second action, called 
"Run", which has the original file association (C:\Python21\python.exe "%1" 
%*).  That way, if I don't want to run IDLE, I can just right-click the 
file and select Run.

[Visualpython-users] which file to associate .py files with?

[<hea...@vn...>]

Hello.

For VPython running under Win9x, to which file should I associate *.py files so that when I click on one, it opens in the modified version of IDLE? As it stands now, clicking on a *.py file causes it to execute. I want to load it into IDLE.

[Visualpython-users] Install Scripts

I've updated the Install Scripts package on the developer's page to update 
the URL for the freeware zip application I'm using. Today I discovered that 
the old obvious URL www.info-zip.org has been taken over by some commercial 
enterprise. The excellent multiplatform freeware zip and unzip applications 
are still available, but buried in a nonobvious place:

[Visualpython-users] Re: Windows 2000 with VPython

[Bruce S. <ba...@an...>]

My physics student provided lots of details (see below). I vaguely remember 
having heard of this bug -- that IDLE comes up on Windows, and one can 
edit, but F5 does nothing. Does anyone recall seeing this before, and what 
the problem was? Can it be that the networking on a particular computer 
could be messed up in such a way that IDLE can't open a socket to start the 
other process?

Re: [Visualpython-users] RPM for redhat 7.1

[Michael Katz-H. <mi...@go...>]

Can you post a src rpm?

I get the following dependency errors...

libgcc_s.so.1   is needed by visual-20010828-3
libgtkgl.so.5   is needed by visual-20010828-3
libstdc++.so.3   is needed by visual-20010828-3

I guess the gcc and stdc++ are version 3.0 which is not installed on any
major distrib. yet.

[Visualpython-users] Visual on Andrew

[Ari H. <ahe...@an...>]

Hi,

This is only really relavent to people at CMU.

Rolf Braun and I have fixed the remaining issues with his old setup of
Visual on AFS, and I have replaced it with a setup on my account, using the
latest Visual.

It can be accessed on the Linux machine in Wean by running
~aheitner/python/visual.

It's possible I'll get around to compiling a version for Sun, though it
won't run extraordinarily well.

I'll try to keep things working, although this will be the version I'll be
developing against for my research this semester.

I'd appreciate hearing whether this works for people.

[David A. <dm...@an...>]

Yes.  To my considerable chagrin I realized I must have mis-run one of the 
early experiments (probably by forgetting to do the "make install" or to 
copy cvisualmodule to site-packages).

Replacing the getattr_methods call in pvector/getattr does solve the 
problem.

I've been using VPython on W2k with no problems for some time now.

What happens when you hit F5 in an IDLE window?

I'm currently a Physics student, just learning VPython... i'm having a

In order to do so, I have to actually go to the directory and double-click 
on the *.py file I wish to run. Unfortunately, this makes debugging VERY

<sigh> indeed it does work on Debian :)

I wish I could be more useful in debugging this one ...

I've stepped thru the code a few times, but I don't yet claim to have any 
understanding of what is going on....

Note that things work fine on Windows and on Debian.

Re: [Visualpython-users] rpm for redhat 7.1

[Randall A. J. <Ran...@gs...>]

Sure enough, it seg faults under RH 7.1.

Let me see if I have the details correct.
dot is provided by Numeric, vector is provided by visual.
so the following code should break as well.
--
from visual import *
dot(vector(0,0,0),vector(0,0,0))
--

and this is equivalent to:
--
import visual
import Numeric
Numeric.dot(visual.vector(0,0,0),visual.vector(0,0,0))
--

But... this code works; passing tuples to dot instead of vectors.
--
from visual import *
dot((0,0,0),(0,0,0))
--

It seems that Numeric.dot is not happy with visual.vector arguments.
How much investigation has been done into the bug?

There are tools for building the deb in CVS -- just check out all the CVS
modules, and run the 'make-tar.sh' in the cvisual/ module.

I think the last deb's I built and sent along (which are not on the webpage)
are against an out-of-date libgtkgl4. I haven't replaced those packages,
since the packages should be in the Debian unstable distribution in a couple
of weeks.

I recently compiled/installed under RH 7.1 and I haven't had a problem,
things seem to work.  I don't think I've exhaustively tested all the
demos/features though.  I'll do that and let you know if things work.

[Visualpython-users] Bug on redhat 7.1

[David A. <dm...@an...>]

On the off chance that someone has an insight:

I've been wanting to build an RPM for RedHat 7.1 but have been held up by a 
difficult bug that affects several of the demo programs.

The following short VPython program segfaults:

from visual import *
value = 1.0
pos = vector(-1.01475,0.0876125,0)
axis = vector(0,1,0)
value = value*dot(pos,axis)

The following code in "getattr_methods" crashes deep in the "throw" 
machinery:

virtual Object getattr_methods( const char *_name )
		{
		STD::string name( _name );

		method_map_t &mm = methods();

		if( name == "__methods__" )
			{
			List methods;

			for( method_map_t::iterator i = mm.begin(); i != mm.end(); ++i )
				methods.append( String( (*i).first ) );

			return methods;
			}

		// see if name exists
		if( mm.find( name ) == mm.end() )
			throw AttributeError( name );

I've been wanting to build an RPM for RedHat 7.1 but have been held up by a

If you speak CVS, you can get the complete source for VPython from
