[AG-DEV] UCL common library & VPMedia

[Andrew Ford]

Hi Tom,

Thanks, I was able to compile VPMedia with that copy of common. Judging by
the differences between the two, it looks like set_umtp_dest got removed
entirely. Piers, is this expected?

I started attempting to compile VP, but I'm running into some issues with
the SConstruct script:
-the check for XMLRPC fails, and it seems to have had some major API changes
(assuming the xmlrpc-c in the Ubuntu package repository is the most recent),
so that won't be usable without major changes in VP,
-the TryLink for GLEW fails, but when I try to run the code standalone it
works fine,
-the script itself breaks:
TypeError: list indices must be integers:
  File "/home/andrew/work/VP/VP/SConstruct", line 702:
    print env['CPPDEFINES']['VP_VERSION']

env['CPPDEFINES'] should be a dictionary, but at some point it apparently
gets turned into a list. I think this happens in myParseConfig, but it's
hard to tell as my Python is pretty weak. Has anyone worked with
VP/successfully compiled it recently?
