[Visualpython-users] Seg Fault if using control-field and a box in a scene

[Sebastian S. <sch...@go...>]

 Hello,
I'm new in Vpython. I have designed a 3D modell in vpython to interact with
them. The mathematics, displaying the 3D modell - all fine.

After this I wanted to make a controls-field with buttons and I always get
a segfault. After some hours I have compiled the newest vpython version
5.74 (+modules) and still the same problem.

Thank you for your help,
Best Regards, Sebastian Schleitzer

I too find that recent versions of Ubuntu offer non-working versions of the
package python-visual, and I don't know why building a new version also
fails. Steve Spicklemire has been doing excellent work in making an easy to
use Linux installer for the new wxPython-based VPython, which is quickly
getting quite mature. Perhaps Steve can post something about the status of
his installer.

[Steve S. <st...@sp...>]

I'll try to modify the setuptools script to work on visual 5.7x and post if I can get it to work. That may permit you to build a fresh version in your environment.

Re: [Visualpython-users] Seg Fault if using control-field and a box in a scene

[Sebastian S. <sch...@go...>]

The building process of vpython was successfull. Also my project was
running without problems. The only problem was the control window and the
box in the second scene.
If i comment the box-create line and uncomment the controls it works.
If i uncomment the the box and comment the controls line it also works.
Both lines uncomment - seg fault.
(The code is only an excerpt of my project)

Thank you for your patience and sorry for my bad english
Sebastian

Re: [Visualpython-users] Seg Fault if using control-field and a box in a scene

[Steve S. <st...@sp...>]

Hi Sebastian,

First.. everything below assumes you're working with Python-2.7.

We have also experienced trouble on Ubuntu 12.10. If you don't want to build the experimental vpython-wx from source I've built a linux .egg file and posted it here: https://dl.dropbox.com/u/20562746/VPython-6.01-py2.7-linux-x86_64.egg

You can install it using the setuptools "easy_install" command line program:

sudo easy_install https://dl.dropbox.com/u/20562746/VPython-6.01-py2.7-linux-x86_64.egg

The good news is that this will get you the latest experimental version of visual python, (which I've tested with your program on Ubuntu 12.04 anyway, and it appears not to crash) without having to build from source.

The bad news is that it depends on having wxPython 2.9.4 installed, and that probably requires building from source (see INSTALL.txt here for instructions <https://github.com/BruceSherwood/vpython-wx/blob/master/INSTALL.txt skip the part about building vpython, and go straight to the wxPython part.)

In case that's not possible, I've also posted a tarball of my wxPython libraries but there's no guarantee they will work on your system:

https://dl.dropbox.com/u/20562746/wxPython-2.9.4-linux_ull.tgz

You can install them manually if you like:

sudo tar -C / -xzvf wxPython-2.9.4-linux_ull.tgz

Of course you'll still need Polygon, TTFQuery and FontTools installed for text, etc. I'm guessing you have those around from the older vpython?

Realize that this all circumvents your package manager and may have to be undone manually if you decide you want to "go back".

If you decide to try this.. please let us know how it comes out! Sorry it's not simpler... we're working on that!

thanks,
-steve

Re: [Visualpython-users] Seg Fault if using control-field and a box in a scene

[John Z. <joh...@wa...>]

Hi All,

I love all the work going on in the Wx version of VPython. I can't wait until I have some time to try it out. Just for the record, I want to point out that Sebastian's test program runs fine (no seg fault) on my 64 bit Ubuntu 12.04 that just uses the standard Ubuntu python-visual package (with the libgl-mea fix reported on the VPython download page). I am wondering if the downgrade of the libgl might also fix the problem on 12.10, but I have not yet had a chance to try it, as all my machines are on 12.04 at the moment.

--John

ps. Thanks Bruce and Steve for the rapid progress on the new VPython. This should be a real boon for the VPython community.

Re: [Visualpython-users] Seg Fault if using control-field and a box in a scene

[Steve S. <st...@sp...>]

Also... for what it's worth, I've build and posted .egg files (which are easy_install'able) for Polygon, TTFQuery and FontTools here:

https://dl.dropbox.com/u/20562746/fonttools-2.3-py2.7-linux-x86_64.egg

https://dl.dropbox.com/u/20562746/Polygon-2.0.5-py2.7-linux-x86_64.egg

https://dl.dropbox.com/u/20562746/TTFQuery-1.0.5-py2.7.egg

These are built on/for Ubuntu 12.04 x86_64. They may also work on your 12.10 system.

The good news about these is that they can be uninstalled using the "pip" utility.

Enjoy! Let me know how it goes...

If you've created the setup.py with all its magic already, wouldn't it
be worth putting that up onto PyPI [http://pypi.python.org]? This way
anybody could just install it using pip without the need to download,
etc. You can also have custom build/compile steps in the setup.py, so
that the C/C++ parts can be compiled on the target machine upon install
via pip. The PyMongo project for example has this solved really nicely,
where the pip install works smoothly, and even defaults back to a pure
Python driver in case build tools (GCC, etc.) are not available.
Obviously that fallback won't be an option here, but the pip install
magic via PyPI would step VisualPython up another notch.

Re: [Visualpython-users] Seg Fault if using control-field and a box in a scene

[Steve S. <st...@sp...>]

Hi Guy,

That is the ultimate idea when things settle down...  I was thinking that we needed to get some more input from testers before putting anything on pypi, but I've never actually released anything there, so I'm not certain of the exact protocol. Is it not expected that most of the packages there are stable releases? The other issue is our dependency on wxPython 2.9.4. Even the wxPython folks don't have binary releases yet, and the package managers (that I've seen) are still on 2.8.x. If I'm wrong, I think it's a great idea!

thanks,
-steve

Not necessarily. You're adding "Categories" to each entry, which consist
of key-value pairs. One of these categories is "Development Status",
which you can just declare to be "Alpha" or "Beta". Here's a link of one
of my projects that's in alpha to show what I mean:

http://pypi.python.org/pypi/matanui

That is certainly a problem for a fully automated process. However, I
think a bit of documentation on the PyPI entry goes a long way in
explaining that. However, you can put a dependency into the meta-data of
setup.py, which declares that as well. I can see that there's also a
2.9.x wxPython in PyPI, so it can also be pip installed *automatically*
when installing wxVisual through pip.

http://pypi.python.org/pypi/wxPython/2.9.1.1

Maybe that requires first installing the native 2.9.x wx widgets, but as
I said, a bit of documentation ...

> If I'm wrong, I think it's a great idea!

Go for it. I'd be keen to see it this way. It would open up a whole
different population of users. Additionally, the setup.py provided
meta-data can also be very useful for package maintainers of
distribution packages. Talking about distro packages: with stdeb, one
can also retrieve PyPI packages, have them automatically rolled into a
.deb package and installed, keeping the package management nice and
clean ...

Re: [Visualpython-users] Seg Fault if using control-field and a box in a scene

[Sebastian S. <sch...@go...>]

Thank you very much for providing me the binaries.

Unfortunaly, it was not compatible (I remember a libboost-x.<49 not 
found, tried to make symlinks, no luck, it doesn't start)

So I compiled wxPython and VPython6 from source.

Now my project has some view problems and the mouse-object-picking. The 
3d modell is a kind of sphere, only composed of cylinders, vectors: 
(0,0,0)-->surface of sphere

I think I have to switch back to vpython 5

Best regards
Sebastian
