I am on Ubuntu 8.10 and have not used any other Linux.

I agree this is an installation problem, but I still don't know how to
fix it.

I downloaded GNAT GPL 2009 from Libre. I unpacked using the GUI
decompress program available from the Ubuntu menu and it ended up in
directory /home/ken/Desktop/gnat-2009-i686-gnu-linux-libc2.3-bin. I
used the doinstall script in this directory and gave the install base
direcory as /usr/gnat as suggested. Installation ran to completion
without errors and I added /usr/gnat/bin to the $PATH as the doinstall
script prompted me to do.

Result: I could enter the new GPS program, but it failed compiling Ada
and C with errors shown in my previous post.

I guess this has something to do with grpbuild. There is a gprbuild in
the old GNAT GPL 2008 install directory, but there are no gpr-related
files in the new install directory at /usr/gnat.

GNAT GPL 2008 is available via the Ubuntu Synaptic Package Manager (a
GUI front end for the commandline package manager) I used Synaptic. No
luck, still the same. I tried the commandline too by sudo aptitude
install gnat gnat-gps gprbuild and got message 'Couldn't find any
package whose name or description matched "gprbuild', so gprbuild is
not available via the repository used by ubuntu.

How do I install GNAT GPL 2009 on Ubuntu?
