Sorry, I have no idea. Since the error mentions threads, I will comment
that threads have been eliminated from VPython 6.

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

Hmm.. I've never hit that one.

I haven't experimented with linking to dylibs for boost, so I'm probably not going to be much help there.

Maybe Bruce will know if that's been tried.

sorry!

Re: [Visualpython-users] VPython 6.02 with buttons, sliders, and new event handling capabilities

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

Hello Steve,

I did read that, but I have't tried yet. I'm interested in trying to install boost with homebrew.

I made a few changes with the boost installation complied by homebrew (I not do their basic install for 10.8. Before I had chosen some options that I didn't really need).

The strange c++ error has gone. Instead 'import visual' generated the following Fatal error:

Fatal Python error: PyThreadState_Get: no current thread
Abort trap: 6

Do you think this could be because I linked with the dylibs. I remember when I did some ctypes work with python on OSX that there was a problem importing dylib files that gave a similar error.

Best wishes,

Dan

Hi Dan,

When you built boost did you use the bootstrap/b2 parameters suggest in MAC-OSX.txt or some variation?

I think __ZN5boost6python7objects15function_objectERKNS1_11py_functionERKSt4pairIPKNS0_6detail7keywordES9_E is a c++ mangled name for some specific method, but it's not included in your library somehow.

Re: [Visualpython-users] VPython 6.02 with buttons, sliders, and new event handling capabilities

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

Hello Steve, Tom,

find /usr/local/lib -name *boost_python* -ls reveals that there is a .dylib and .a versions, symlinked to /usr/local/lib,

/usr/local/lib/libboost_python-mt.a -> ../Cellar/boost/1.52.0/lib/libboost_python-mt.a
/usr/local/lib/libboost_python-mt.dylib -> ../Cellar/boost/1.52.0/lib/libboost_python-mt.dylib

So Tom suggestion was right, the libraries have a "-mt" appended.

I changed line 135 of setup.py to read,

libraries = ['boost_python-mt','boost_signals-mt'] 

I re-built. This time the build finishes successfully, but there is error when import visual in python:

----------------------------------
  File "/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/VPython-6.02-py2.7-macosx-10.8-x86_64.egg/visual/__init__.py", line 33, in <module>

---------------------------------

I think the function named "__ZN5boost6python7objects15function_objectERKNS1_11py_functionERKSt4pairIPKNS0_6detail7keywordES9_E" is a hint that headers didn't get processed or some obscure problem with building against a dynamic library (the .dylib) files.

Any suggestions? 

The includes directory has the following structure,

/usr/local/include/boost/<all boost files and folders>

Should I specify the boost subdirectory as,

[build_ext]
include-dirs=/usr/local/include/boost <---- ?
library-dirs=/usr/local/lib

Should I only link against the static library (is that what the .a files are?). If so, how to do that?

Best wishes,

Dan

PS. I should probably say, this is a fresh install of 10.8.2, with a latest Xcode (4.6), and latest homebrew (0.9.4, completely up-to-date).

Re: [Visualpython-users] VPython 6.02 with buttons, sliders, and new event handling capabilities

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

Hi Dan,

What version of boost did you build?

"Library not found" probably means /usr/local/lib is not the right place. ;-)

Can you try something like:

find /usr/local/lib -name libboost_python.a -ls

to see where it's hiding, and then change setup.cfg to point to:

library-dirs=/path/to/where/it/lives

Re: [Visualpython-users] Visualpython-users Digest, Vol 80, Issue 1

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

Since you have a 32 build of enthought... you'll need to link with a 32 bit build of boost. The instructions in MAC-OSX.txt (unfortunately for you) describe building a universal boost to match the current python binaries available at python.org. 

Here's what's in MAC-OSX.txt:

> ./bootstrap.sh --with-toolset=gcc --with-python-version=2.7 --with-python-root=/Library/Frameworks/Python.framework/Versio\
> ns/2.7 --with-python=python2.7 --with-libraries=python,signals
> 
> to create the bjam tool and project-config.jam.
> 
> In the file project-config.jam, change "using gcc ;" to "using gcc : 4.2 : g++-4.2 ;"
> 
> Now execute this, to build Boost libraries for both 32-bit and 64-bit architectures:
> 
> ./b2 link=static threading=multi toolset=darwin cxxflags="-arch i386 -arch x86_64"
> 

Maybe try:

./bootstrap.sh --with-toolset=gcc --with-python-version=2.7 --with-python-root=/Library/Frameworks/Python.framework/Versio\
ns/7.3 --with-python=python2.7 --with-libraries=python,signals

./b2 link=static threading=multi toolset=darwin cxxflags="-arch i386"

??

I don't know.. I may try to build with enthought at some point.. but alas, no time soon.

Looking into the right library directory seems to work. Are you sure,
there is a libboost_python.so in there? It might also be that there is
only a libboost_python-mt.so, so you need to link against that and
change the "-lboost_python" to "-lboost_python-mt".

Greetings,
   Tom

Re: [Visualpython-users] VPython 6.02 with buttons, sliders, and new event handling capabilities

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

Hello everyone,

Continuing from my earlier question, I have now installed all dependancies using a combination of homebrew (http://mxcl.github.com/homebrew), pip and good-old python setup.py  installing…

Things seem to build fine, but I have a linking problem with boost. My boost includes and library files live in the usual places /usr/local/include and /usr/local/lib (well symlinks managed by homebrew).

Any ideas on how to tell the install script the location of boost?

I have edited the site.cfg to read,

[build_ext]
include-dirs=/usr/local/include
library-dirs=/usr/local/lib

The list lines of the error reads,

---
-L/usr/local/lib -lboost_python -lboost_signals -o build/lib.macosx-10.8-x86_64-2.7/visual_common/cvisual.so
ld: library not found for -lboost_python
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'c++' failed with exit status 1
---

Any ideas?

Best wishes,

Dan

Re: [Visualpython-users] version 6.02

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

Thanks much for the report. I think we must not have tested scene.visible =
False.

It's very gratifying that you found that (essentially) all of your programs
work. When we started on this conversion to wxPython, it wasn't obvious to
me that it wouldn't require rather serious changes to the API, but we got
away with little change.

Be sure to read the file OSX.txt in the tarball, which includes
instructions on how to build the Boost libraries that you'll need.

[Visualpython-users] version 6.02

[Symion <kn...@ip...>]

I have installed Visual Python version 6.02 onto Python version 2.7.3 as 
instructed.

This anomaly has probably been picked up already.

'scene.visible = False' does not seem to close the window.

The only problems i have encountered are entirely related to my programs 
not have a rate(n) inside a loop or
having a rate 'n' less than 1.
Also, a fonts issue regarding bad font names - but again that was easily 
fixed by using either 'sans', 'serif' or 'monospace'.

Apart from that, EVERY single Visual Python program I have written so 
far - WORKS!

This is great stuff!!

Symion

Re: [Visualpython-users] Visualpython-users Digest, Vol 80, Issue 1

[Scott H. <sc...@fl...>]

I'll give that a try. I do have vPython 6 running now with an "official" 2.7.3 python. 

I appreciate your efforts quite a bit! I've used VTK and wxPython heavily in the last, and it's great to be able ti integrate wx and VPython!

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

(I should mention that Adam Hausknecht's problem had nothing to do with
VPython. The Tk package is broken on the Mac; for a fix, see
http://www.python.org/getit/mac/tcltk/.)

You could try building from source, because Steve Spicklemire has made this
quite easy to do, except that you may have difficulties dealing with
installing all the dependencies (wxPython 2.9.4, numpy, FontTools,
ttfquery, Polygon). Get the source "tarball" from the Linux download page
at vpython.org, unpack, and in a terminal cd to the source code, then
execute "sudo python2.7 setup.py install".

Re: [Visualpython-users] Visualpython-users Digest, Vol 80, Issue 1

[Scott H. <sc...@fl...>]

I too use EPD. On my machine, the VPython installer doesn't detect EPD and won't install. I'm on OS X 10.8.2

This is my python:

Enthought Python Distribution (EPD) free version -- www.enthought.com
Version: 7.3-2 (32-bit)
(type 'upgrade' or see www.enthought.com/epd/upgrade to get the full EPD)

Python 2.7.3 |EPD_free 7.3-2 (32-bit)| (default, Apr 12 2012, 11:28:34) 
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin
Type "credits", "demo" or "enthought" for more information.


Getting VPython to work with EPD would be great.

Thanks,

The program I tried is : 


------------------------------- 

from visual import * 
sphere() 
---------------------------- 


Also, a VPythom folder with sample programs is NOT created. Thus, the "visual" help item on VIDLE'S help menu also fails. 


Finally, I also use Enthought's Python distribution for scientific computing. Could these interfere with each other? 
Can Visual Python be installed within Enthought's distribution? I think Enthought uses a Numpy 1.6x. 


Regards and thanks for all your work!

Hi, 

I have been using Vpython on Windows 7 and XP machines, either 
with EPD(enthght python disribution) and Pythonxy distribution. 

It is amazing. Then I installed Vpython(Ver 5.74 for win32 on 
python2.73) on an windows-8 tablet (ASUS ME400c, Atom Z2760, 
2GByte memory). However, it does not work. The "Vypthon" window 
opens but it hangs up. 

Does anyone know how to do with it? I keenly would like to show 
the physical simulation to students on my physics lecture. 

Thanks in advance.

Owen Long has contributed an interesting program that displays the odd 
behavior of a book rotating in 3D space, now available in the Contributed 
section of vpython.org. 

Because there are no torques acting on the book, the (vector) angular 
momentum does not change, but the (vector) angular velocity does change, 
and the visual effect is that the book tumbles in an unexpected way. 

You can see this effect in the real world. Try flipping a book or a tennis 
racket in the air. You'll find that if the object rotates around its long 
axis or the axis perpendicular to the largest side, the rotation is stable. 
If however you flip it around the third axis, no matter how carefully you 
try to flip it exactly around that axis, you'll see that the object tumbles. 

Bruce Sherwood 

P.S. Steve Spicklemire and I believe that we're very close to the next 
release of the wxPython-based VPython 6. All that remains is some 
documentation and some cleanups of keyboard issues.

Now available on the download pages at vpython.org is VPython 6.02, the 
product of a collaboration between Steve Spicklemire and me. This version 
is based on the cross-platform library wxPython. It has two powerful new 
features: 

(1) You can put a VPython 3D display in a window that also has wxPython 
buttons, sliders, etc. that have a native look and feel on all platforms. 
See the new example program widgets.py. (We haven't experimented with 
automatic layout mechanisms provided by wxPython, which may require some 
revision of the new VPython.) 

(2) In addition to the existing ways to handle mouse and keyboard events, 
there are powerful new "callback" mechanisms for handling events. Among 
much else, this provides a way to catch keyboard release events, which some 
users have wanted for a long time. 

Our experience so far is that existing programs will run with VPython 6.02, 
unless there is an animation loop that does not contain a rate() statement 
(which is now obligatory), and if you import graph or controls or 
filedialog you must first import visual or vis. We encourage you to try 
your programs and provide test cases that do not run properly even after 
making these two adaptations. 

There is one known bug with old programs, which is that materials.rough and 
materials.marble do not display correctly on a Macintosh, and the cause is 
currently unknown. 

There is one known bug with new programs, which is that pull-down menus (a 
new feature made possible thanks to wxPython) do not work on a Macintosh. 
This problem is partly understood, but there isn't yet a fix for the 
problem. 

There is a likely bug on Linux, in that wxPython does not currently report 
window metrics such as the height of a menu bar. For that reason, at the 
moment these metrics are hard-coded and are likely to be wrong for some 
Linux or some window manager on some Linux. Please let us know about your 
experience in this regard.

P.S. At the start of every semester there is a big spike in VPython 
installer downloads due to the start of classes in which VPython is used. 
Last month there were about 10,000 downloads, and there were considerable 
charges for excess data transfer from the vpython.org web site. For that 
reason, the installers have been moved to sourceforge.net, which provides 
free downloads for open-source projects like VPython.

One other thing: There isn't a version of VPython 6 for Python 3.x because 
there isn't yet a Python 3.x version of wxPython, on which VPython 6 is 
based. The wxPython developers are actively working on a version for Python 
3.x, but I don't know when it will be available.

My mistake. I had misunderstood the status of the "Phoenix" project, a 
rewrite of wxPython that can be used with Python 3. I just now tried using 
the Phoenix version, and after some very minor changes just about 
everything but labels worked (and that's probably easy to fix).

Re: [Visualpython-users] VPython 6.02 with buttons, sliders, and new event handling capabilities

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

If you try 6.02 on the Mac, you need the following information, which has
been added to the Mac download page at vpython.org:

If you have an existing VPython, you will need to delete the old folders
visual, vis, and vidle from

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

A similar comment applies to Linux. The issue is that our Mac installer and
Linux build machinery places the folders visual, vis, and vidle (and
visual_common) inside one folder, so the old folders don't get overwritten.
The Windows installer overwrites the old folders.
