[Visualpython-users] Netbeans IDE

Any anyone been able to get vPython running under netbeans? At first I thought it might be as simple as including the visual library, but so far have not been able to get things running. 

Thanks,

I can't answer your other questions, but this one I can: There is no 
such reason. Fink (an older "community driven package manager for 
MacOS") has vpython version 5.40 (package visual-py27) that builds OK in 
the 64bit tree.

[Visualpython-users] Building 32-bit/64-bit vpython on MacOS?

[Daniel F. <boy...@gm...>]

Dear list,

I have recently discovered the Homebrew project, which is a fantastic
community driven package manager for MacOS,
http://github.com/mxcl/homebrew . Using this and pip
(http://pypi.python.org/pypi/pip) I have build a really stable python
environment, both 32-bit and 64-bit on MacOS including numpy, scipy
etc.. I would now like to add vpython to the stack. Currently, I'm
using the pre-compiled 32-bit version from the installer and it works
really well with my python environment. However, this fails when
imported from the 64-bit python. So my questions:

* How easy would it be to provide a 'brew' for vpython specific to MacOS?

* Could a more general installer for vpython be added to the pip
package manager?

* Is there a fundamentally reason for sticking to 32-bit (e.g.
dependency difficulties?)

Best,

Dan

Unfortunately a *very* common problem when people unaware of that try to 
install something from sources and forget to first remove the distribution's 
version. Tinkering around wildly in the presence of two competing installs 
with no precautions taken for separating the properly can be hell through 
poking around with a thick stick in a dark hole.

[Bruce S. <Bru...@nc...>]

For what it's worth, Visual works fine for many people on Ubuntu
10.10, both the package python-visual and building from source. Thanks
for the link to a bug report. This is very puzzling and frustrating,
and I don't see how to get at the problem, which presumably is
hardware-related, and/or an issue with particular graphics drivers.

Re: [Visualpython-users] Building vpython 5.4 in Ubuntu 10.10

[Patrick S. <pat...@gm...>]

Never mind, I tried compiling again, this time doing it from the source
directory rather than creating a new directory, and I got it to work and
install properly.  I also had to install the Polygon, fonttools, and
ttfquery modules to get visual to load (I missed that part in the
INSTALL.txt instructions last time).

Unfortunately I still have the same problem with the version I compiled
as I was having with the python-visual package from ubuntu's
repositories.  When I open a vpython window by doing say:
import visual
visual.sphere()
I get the error message:

i915_program_error: Exceeded max instructions (318 out of 123)

and vpython runs extremely slow (interacting with the mouse takes 5-10
seconds to respond).  3D graphics seem to work very well otherwise on
the computer, so I thought it might have been a problem with ubuntu's
version of visual python, but I guess it must be something else.  After
googling, I found some people with the same problem:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=598896
but nobody seems to have found a solution.

Re: [Visualpython-users] Building vpython 5.4 in Ubuntu 10.10

[Patrick S. <pat...@gm...>]

Thanks for your reply!  Unfortunately, for me running sudo make install
just copies the cvisualmodule.so file
to ../visual-5.4_release/site-packages/visual/cvisualmodule.so.  Here's
what I did in detail:

1. Make a directory on the same level as the source directory, and copy
visual-5.4_release/src/gtk2/makefile into it. (I also had to edit a
couple of things in the makefile: I changed the name of the source
directory to visual-5.4_release from vpython-core2, and changed the
-lboost_python-mt flags to -lboost_python-mt-py26, since that's how the
libraries are named in Ubuntu)

2. I ran configure from the newly created directory with the makefile in
it, with the --prefix=/usr argument.

3. Ran make from the same directory

4.  Then when I run sudo make install, it just says 
cp cvisualmodule.so ../visual-5.4_release/site-packages/visual,
and nothing gets copied into /usr/lib/python2.6

Thanks for your help,
Patrick

Re: [Visualpython-users] Building vpython 5.4 in Ubuntu 10.10

[Bruce S. <Bru...@nc...>]

You need to execute "sudo make install" to move the various components
into the right places. For cleanliness, it would be a good idea first
to remove the Visual stuff from site-packages.

Also, because site-packages is no longer (alas) on the Ubuntu Python
module search path, you need to follow these instructions in
INSTALL.txt:

       You will also need to copy vpython-core2/src/gtk2/site-packages.pth to
       /usr/lib/python2.6/dist-packages to put /usr/lib/python2.6/site-packages
       on the Python search path.

You will have to adjust the contents of site-packages.pth text file if
you are installing to /usr/lib rather than /usr/local.

Hope this helps!

[Visualpython-users] Building vpython 5.4 in Ubuntu 10.10

[Patrick S. <pat...@gm...>]

I tried building visual python 5.4 following the directions in the
INSTALL.txt file.  I made a directory at the same level as the
"visual-5.4_release" source directory and ran configure and make.
Everything seems to work fine, and the cvisualmodule.so file is
generated.  

The only thing I'm confused about is that running "make install" just
copies the cvisualmodule.so file back into the visual-5.4_release
directory.  I'm just not sure which files I am supposed to move where to
be able to use vpython.  I tried just copying the whole
"visual-5.5_release/site-packages" directory into
"/usr/lib/python2.6/site-packages" (making sure it was in python's
search path), but I'm not able to load visual.  Doing "import visual"
gives the error:

ImportError: cannot import name cvisual

cvisualmodule.so is in the /usr/lib/python2.6/site-packages/visual
directory, but it apparently can't be imported.  If anyone can help me
figure out what's wrong I'd greatly appreciate it.  Thanks.

Re: [Visualpython-users] a problem

Often that means that the graphics driver needs to be updated. On the
other hand, I think there hasn't been a lot of experience with Visual
on 64-bit Linux.

Re: [Visualpython-users] Background color of text

[Bruce S. <Bru...@nc...>]

It would seem to be an inconsistency that currently there isn't a way
to change the background of a label.

However, note that you can change the opacity, so that setting
opacity=0 (and perhaps box=False) may do what you want in your
particular case.

label currently honors scene.foreground but not scene.background; a
fix would be an incompatible change but probably worth doing.

[Visualpython-users] Background color of text

[Poul R. <Pou...@sk...>]

How can I control the background color of some text in a label (see
example below - I would like a white background).

Poul Riis


from visual.graph import *

pgraph = gdisplay(title='p vs t', xtitle='t (s)', ytitle='p (Pa)', x=0,
y=0, xmax=100, ymax=20, width=500, height=215,foreground=color.black,

Re: [Visualpython-users] Python 2.7.1 and VPython 5.4 on OS X 10.5.8 broken?

The next thing is to see whether there is in fact anything inside the
numpy folder.

Also, in a terminal try this:

> python2.7

You should see [0 1 2 3]. This test rules out issues with VIDLE or Visual.

I assume these are Intel Macs?

[Bruce S. <Bru...@nc...>]

The code in /ttfquery/glyph.py looks like this:

try:
    import numpy as Numeric
except ImportError, err:
    import Numeric

So the real problem seems to be that numpy isn't installed, which is
odd, since the VPython installer installs numpy.

Please report what folders you see in

    /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/

There should be a numpy folder.

[Visualpython-users] Python 2.7.1 and VPython 5.4 on OS X 10.5.8 broken?

[Joe H. <hea...@gm...>]

I'm trying hard to update my classroom MacBooks running 10.5.8 to Python 2.7
and VPython 5.4. However, upon running

from visual import *
sphere()

from VIDLE I get this:

Re: [Visualpython-users] Help on linking?

[Bruce S. <Bru...@nc...>]

I got farther still in trying to build Visual for Python 3 on Ubuntu
10.10. I rebuilt the Boost libraries for Python 3.1 with an option for
longer library names (--layout=versioned) which inserted (in my case)
-gcc44-mt into the library names. Now I could put these in /usr/lib,
because libboost_thread for Python 2.6 doesn't conflict with
libboost_thread-gcc44-mt for Python 3.1. I put the folder of boost
includes in my own location, which overrode looking in
/usr/include/boost.

However, although I can build and link and install, when I try to
import visual, an import error occurs on trying to import the C++
component, cvisual. The import error message is

"dynamic module does not define init function (PyInit_cvisual)"

This sounds like a failure of the Boost mechanisms to tag the cvisual
entry point properly.

Sigh. I don't know what to try next. I would of course be interested
to hear from anyone who has attempted to build Visual for Python 3.1
on Ubuntu (or other Linux, for that matter).

Re: [Visualpython-users] running on Ubuntu 10.10

[Bruce S. <Bru...@nc...>]

I don't think this link is relevant. It refers to older versions of
Ubuntu on which python-visual was broken. It works okay on Ubuntu
10.10.

Joe,
Try running IDLE from the terminal.

See if that stops the window from closing.

[Visualpython-users] visual on opensuse 11.3 (64bit)

[Weigel, H. <we...@su...>]

Hi all,

since some time I am trying to install visual 5.4 on opensuse 11.3 (64bit) w/o
success. Configure, make and make install run w/o errors but 'import visual'
 causes a segmentation fault. On the web I found a hit that in one case
'import wx' , 'import visual' worked, but not for me.

In order to get make to run I had to create a symbolic link on /usr/include :
 
lrwxrwxrwx   1 root root     60 2010-12-16 19:04 numpy -> /usr/
lib64/python2.6/site-packages/numpy/core/include/numpy//

so that files like arrayprim.* could be found.

Any further advise is highly appreciated.

Fyi 'build.log' and 'config.log' are attached as a single tar.gz file.

Regards,
Herbert.

Re: [Visualpython-users] Help on linking?

[Bruce S. <Bru...@nc...>]

I got a little farther. Although the documentation looks like
--library-path and -L should be synonyms, it seems like they aren't.
With -L I do find the libraries for Python 3. But then when I try to
run Visual, "import cvisual" fails because there's a search for
libboost_python in /usr/libs which finds a version for Python 2.6,
even if I've copied the Python 3 libraries to /usr/libs. The
fundamental problem is that I don't see how to use distinctive names
for the Python 3 libraries, such as "libboost3_python" instead of
"libboost_python".

I also tried ld -static and produced a large static library. But
"import cvisual" is apparently unable to deal with a static library on
Ubuntu.

[Visualpython-users] Help on linking?

[Bruce S. <Bru...@nc...>]

I'm trying to build Visual on Ubuntu (10.10) for Python 3.1, where the
standard Python is Python 2.6, and the Boost 1.42 libraries are
installed for this version of Python.

I've built the Boost 1.43 libraries for Python 3.1 and placed in my
own space the Boost folder of include files and, in a folder beside
the include files, the boost_python, boost_signals, and boost_thread
libraries. I altered the make file to specify linking these libraries
from my own directory rather than from the standard locations, as
follows:

ld ..... --library-path=mylibs -lboost_python -lboost_signals
-lboost_thread ....

What happens when I build looks like I'm linking against the
Ubuntu-installed libraries for Python 2.6, because when I try to run
Visual, I get an import error referring to
/usr/lib/libboost_python-py2.6.so.1.42.0, which is of course missing a
needed symbol.

Can anyone shed any light on this? Thanks.
