Ada on Linux

["Paul" <pcas1986@bigpond.net.au>]

Hi,
    I'm returning to programming (for pleasure, rather than profit) after a 
few years working mostly as a manager.  I was writing Ada code back in the 
'80s.   Although I've used GNAT occasionally on a windows platform I gather 
it works better on Linux.  However I'm not a Linux expert (far from it!) and 
I'm getting tied up in knots trying to get a development platform working.

I recently bought a licence for VMWare Workstation 6 on Win XP and I'm 
trying to get a Glade/GNAT/GTKAda arrangement working in either Fedora or 
Ubuntu (both installed as host O/S').  Neither installation seems to be able 
to generate Ada code from Glade without errors.  In Ubuntu I've successively 
downloaded various versions of GTKAda, GTK+, GLIBC and other 'dependent' 
packages and all I do is create more errors.
I do seem to have GNAT installed properly as I can compile and link a simple 
'Hello world' test program.

So my question is - does anyone have a simple cookbook/howto to set up a 
GNAT/Glade compilation system on Linux?  Ada code I can write - 
understanding Linux is driving me nuts.  Is there a 'standard' directory 
structure for location of library/include files in Linux?  I'd be grateful 
for some assistance. None of the Linux manuals I've read so far have been of 
much help.  Ping me off list if you prefer.

Cheers
Paul
