[Visualpython-users] VPython 5.22 for Linux (even for Ubuntu 9.10!)

There is now a tar file for building VPython 5.22 available on the Linux 
download page at vpython.org, and at sourceforge.net.

There is a bug in the standard Boost libraries on Ubuntu 9.10, and to 
build VPython you must first install Boost 1.38 libraries from 
https://launchpad.net/~ajmitch/+archive/ppa 
<https://launchpad.net/%7Eajmitch/+archive/ppa>. Be sure to read and 
follow ALL of the instructions; click on everything in sight on that web 
page.

If you're content with the older VPython 5.11 but want to run VPython on 
Ubuntu 9.10, just install these new 1.38 libraries and then install the 
Ubuntu 9.10 python-visual package.

P.S. The problem I had with linking to the Boost libraries turned out 
that in the build machinery the statement for linking the Boost 
libraries was

-lboost_python   -lboost_signals   -lboost_thread

but had to be changed to state explicitly that we want the multithreaded 
versions (even though those were the only ones installed, and even 
though this wasn't necessary in the past):

-lboost_python-mt   -lboost_signals-mt   -lboost_thread-mt

I'm hoping/assuming that this will also work okay on other Linux 
distributions, but I only have access to Ubuntu.
