Re: [Visualpython-users] OS X Native

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

What you want is vpython; vpython-core2 is the experimental work 
Jonathan Brandmeyer is doing to add transparency, surface textures, and 
sophisticated lighting.

I made an uninformed and unsuccessful attempt to compile the boost 
libraries (www.boost.org) on OSX 10.4. First I tried using the gcc that 
comes with, and that didn't work, complaining about something having to 
do with "shared" (libraries). Jonathan had mentioned that the gcc 4.0.0 
that comes with 10.4 was grabbed from the GNU people when it was still 
very unstable, so I tried installing from gcc.gnu.org. There is a recent 
4.0.0 there, but to avoid confusion I tried installing (bootstrap 
install) of gcc 3.4.4, with the parameters specified in 
vpython/INSTALL.txt, which unfortunately failed in a way meaningless to 
me. So I didn't get very far just trying to get an X11 version compiled 
for 10.4.

I will say that installing the old VPython on 10.4 using fink is 
actually quite painless now, thanks to the packaging done by Martin 
Costabel. And you can easily install X11 and Xcode from the 10.4 DVD. 
Building a native-mode Mac VPython would be a wonderful contribution, 
but certainly vastly more difficult than merely installing the old 
pre-boost VPython.
