Re: [Visualpython-users] Problems with exception handling in vpython on Linux

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

I don't understand enough about building on Linux to be sure that it would help, 
but it might be worth building according to the instructions in INSTALL.txt, 
since that's how I've built Visual and it works. Moreover, the configure stage 
will tell you if you're missing certain dependencies. On the other hand, it 
seems possible that there's some incompatibility between Visual and 64bit Ubuntu 
(I only have access to 32bit Ubuntu).

You suspect that "whenever vpython raises an exception, python seg. faults", but 
in your Example 1 there's no reason why VPython would raise an exception.
