Getting GNAT to work on a Mac

Getting GNAT to work on a Mac

[TI Launchpad]

I'm running Mac OSX 10.6. I've downloaded GNAT from www.libre.com, but
that simply produced a folder whose 'bin' subfolder contains a lot of
programs - when I typed "gnat make "hello.adb" in Terminal, it said
that gnat was not recognized as a command. So, I re-installed gcc, and
now I have gcc version 4.2.1. But when I type in "gcc "hello.adb", I
get an error: Ada compiler is not intstalled on this system. I've
fiddled around a little it; now when I type in "gnat" in Terminal, it
lists  a bunch of gnat commands I can use, but I still can't get Ada
files to compile. I have successfully added Ada to my PATH (I think),
by using the command, "export PATH=/usr/local/ada-4.2/bin:$PATH" in
Terminal. Now, when I type in "env" in Terminal, it shows that Ada 4.2
is on my PATH - but GNAT and gcc still don't work! What should I do?
Thanks in advance for your help!

UPDATE: I kinda got it to work by installing GNAT 4.3 from macada.com.
It gives about a page of error messages - but generates a working
executable. Hm.

GNAT GPL 2010 from http://libre.adacore.com/libre/ works perfectly if you
follow the instructions, in my experience.

I don't understand what you mean by 're-installed gcc'? The standard GCC
on Mac OS X comes in Xcode, I'm pretty sure.

After the download, you did do the 'doinstall' step?

You say "GNAT and gcc still don't work", can you show us an example with
the error messages?
