My first attempt was using a Ubuntu appliance in Vmplayer - I will eventually also try a plain Ubuntu box - I'm just downloading the ISO now.
A couple of observations:
after installing all of Codelite and plgins, the first time via synaptic, and then updating CL at the first time it ran, I had to de-insatll all of the plugins before the update wold go.
Now that I have the update installed, I m having problems finding all of the necessary files - I am more of a newb with linux than with CL and WinXP

The current file I seem to need to compile the basic new project I created with CL is wx/setup.h
I'm sure there are other things I'll run into, but that is stopping me at present.
