[Visualpython-users] Instructions for building VPython on MacOSX 10.3 and Python 2.3

[Kelvin C. <kel...@uv...>]

Below is a link on how to build VPython on MacOSX 10.3 using Python 2.3.

http://www.uvm.edu/~kchu/?Page=VPython/ 
BuildingVPython.html&SM=miscsubmenu.html

I built VPython yesterday on a fresh (10.3 eMac) starting completely  
from scratch.  Please let me know how this works for you so that we can  
refine this process and make it as painless as possible.

Good news and bad news

#1:  First, Kevin's instructions were superbly clear and I was able to  
follow them without only one hiccup on a non-clean 10.3 system recently  
upgraded from 10.2.

The hitch came here:

Second, they do seem to have built me a fresh python.  When I type  
visual, I now get

This is apparently unrelated to Python (but I'd still like help!!),  
since I can't run glgears either:

any suggestions??  Might the pango / glib2 hiccup be the issue?

[Kelvin C. <kel...@uv...>]

I'm no expert, but my machine doesn't have pango installed at all.   
Therefore, is it there because you've used it for another package?  A  
quick search through the 10.3/stable directory shows that the packages  
below depend upon pango.  I have gtk+ installed, but not gtk+2.

habanero[~]% find /sw -name \*.info -print | grep -v unstable | grep  
10.3 | xargs grep pango | grep -i depends | cut -d ":" -f 1

/sw/fink/10.3/stable/main/finkinfo/editors/bluefish.info
/sw/fink/10.3/stable/main/finkinfo/games/dopewars.info
/sw/fink/10.3/stable/main/finkinfo/games/dopewars.info
/sw/fink/10.3/stable/main/finkinfo/gnome/gtk+2-2.0.6-4.info
/sw/fink/10.3/stable/main/finkinfo/gnome/gtk+2-2.0.6-4.info
/sw/fink/10.3/stable/main/finkinfo/gnome/pango1-dev.info
/sw/fink/10.3/stable/main/finkinfo/gnome/pango1-shlibs.info
/sw/fink/10.3/stable/main/finkinfo/gnome/pango1.info
/sw/fink/10.3/stable/main/finkinfo/gnome/pygtk2-py23.info
/sw/fink/10.3/stable/main/finkinfo/gnome/pygtk2-py23.info
/sw/fink/10.3/stable/main/finkinfo/net/gaim.info
/sw/fink/10.3/stable/main/finkinfo/net/pan.info

None of them appear to be required for vpython.

No.  glxgears doesn't use either pango or glib2, it directly uses the
X11 protocol.  Visual doesn't use pango or glib2 either, since it uses
gtk+ 1.x.

FYI, Pango is the internationalized text engine for Gtk+ version 2 (and
later).

Thank you for your help and feedback, Mr. Chu.  The only thing about
your instructions that jumped out at me is that I don't think you should
need to add -I/sw/include/gtkgl to CPPFLAGS.  gtkglarea.h is referenced
as gtkgl/gtkglarea.h in the source code.

Also, support for the 'distclean' target in the cvisual subdirectory has
been added to CVS.  Thanks for pointing out that deficiency.

Re: [Visualpython-users] Instructions for building VPython on MacOSX 10.3 and Python 2.3

[Kelvin C. <kel...@uv...>]

Hi Jonathan;

The gtkglarea.h include is a old habit to deal with a bad 
VPython-building experience earlier.  You're absolutely right that it 
shouldn't be in there.

Best,

[Visualpython-users] success on 10.3 yet?

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

Has anyone succeeded in either building VPython or running complete 
VPython programs on OS 10.3 yet? This is the only thing hold up my 
upgrade to Panther on my work Mac.

Cheers,
Joe Heafner

The python IDE that comes up is X-ish of course, and so keybindings for  
commands like Open File  use control -O  rather than the OS X  
command-O.  So I'm trying to get quickeys to make the substitutions for  
me.

I've also found that I can run vpython scripts from OS X environments  
such as that created by voodoopad if I programmatically set the python  
interpreter to /swbin/python,  set the  pypath, and set the display  
variable for the X server.  Thus, this works is X11 is running  
concurrently.

Which has me wondering whether the OS X can be tweaked to provide an OS  
X IDE  But I haven't tried that yet.

Anyway this is a much better place to be.  Thanks to everyone for their  
help.

[Visualpython-users] VPython working on Mac OS 10.3.2

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

Good evening.

Using Kevin Chu's instructions at

<http://www.uvm.edu/~kchu/?Page=VPython/ 
BuildingVPython.html&SM=miscsubmenu.html>

I too have built VPython under Mac OS 10.3.2. I first installed the  
latest Fink and FinkCommander (a graphical front end to the Fink  
system) and all went well until I tried to build gtk+. There was a  
failure somewhere near the end that prevented the built packages from  
being installed. I suspect I goofed something up because I set  
FinkCommander to use the unstable tree so I wouldn't have to copy over  
the python23 info and patch files ad Chu describes. This didn't work,  
so I wiped out Fink and FinkCommander and reinstalled Fink. This time,  
I copied over the info and patch files as directed. However, I issued  
"fink selfupdate" rather than "fink selfupdate-cvs" and all worked fine.

Apple has made bash the default shell now and this caused me to  
stumble. Environment variables must be set as

export CPPFLAGS="-I/sw/include -I/sw/include/gtkgl" (note the quotes  
needed for multiple arguments)
export BROWSER=open

I realize the reference to /gtkgl is not needed. I verified these env  
variables had been correctly set with

echo $CPPFLAGS
echo $BROWSER

I'm curious as to why the LDFLAGS env variable didn't need to be set.  
After a successful build and install using the  
visual-2.1.9-20031005.tar.gz tarball, I fired up X11 and the vpython  
script and got the new IDLE environment and was able to run VPython  
programs. The only issues I see are:

  1) Hitting F1 fails to bring up the web browser with help docs. From  
xterm, I saw that the BROWSER env variable didn't exist so I set it  
manually (X11 apparently uses bash too), and still it didn't work. I  
tried setting this variable in ~/.profile but still no luck, although  
this does set the variable in Apple's Terminal program.

2) X11 doesn't know about /sw in the PATH, so I have to type  
"/sw/bin/vpython &" to start VPython.

 From where do xterm and X11 get information about environment variables  
  under 10.3?

Otherwise, I now have VPython running under Panther.

Cheers,
Joe Heafner -- Astronomy/Physics Instructor

Re: [Visualpython-users] VPython working on Mac OS 10.3.2

[Kelvin C. <kel...@uv...>]

Hi Joe;

Glad to hear that things are working.  Some Unix and fink-related
notes:

1)  To change your shell (back) to tcsh, type:

			   chsh (username)

    and then enter /bin/tcsh at the prompt.

2)  To put vpython in your path, you will need to have /sw/bin in your
    path, which means adding the (appropriate) line to your .cshrc or
    other shell-appropriate startup file.  This procedure is
    documented in the fink install instructions.

3)  X11 and xterm get environmental variables from the shell (ie X is
    a windowing system, not a shell).  

4)  I've amended the posted build instructions to include the
    directions for the bash shell.

I want to keep bash, primarily because I want to learn to use it

I didn't see anything specifically for bash, but I could have surely 
overlooked it. I'll check again.

Any idea why the BROWSER variable doesn't seem to be working? It worked 
fine under 10.2.x and Fink's Python 2.2. I was using the exact same 
VPython tarball too.
