Re: Mixing Cygnus & Gnat compilers on the same machine

["Marin David Condic" <marin.condic.auntie.spam@pacemicro.com>]

Just in case you're ever on a quiz show and the emcee asks you about running
Cygnus with Gnat....... :-)

I installed the Gnat 3.13p I got in the latest "Ada Letters" disk (ASE02_02)
using the gnat-3.13p-nt.exe executable. For reasons I do not understand nor
care to explore too deeply (since everything is fine!) the customary Gnat
commands were not recognized. So I created a batch file with the line:

SET PATH=C:\GNAT\BIN;C:\GNAT\LIB;C:\GNAT\Bindings\Win32Ada;%PATH%

(Don't know if it is going to use the PATH variable to search for bindings.
Oh well, it doesn't cost much!)

Anyway, from here I was able to compile and link your garden variety "Hello
World" program and everything was fine. I don't know off the top of my head
if I need to be executing any other batch files or similar things to
accomplish full visibility of everything Gnat may ever want - I suppose I
should RTFM - but I could apparently find no additional "setup" sorts of
things to do. Maybe someone else knows the answer to that one?

As for Cygnus, apparently all of their search path stuff is being set up by
similar batch files I'm executing when I start up a command line to use
BASH. So depending on where I start my MS-DOS window & which .bat's I
execute, everything seems to be fine.

Now I've not tested very thoroughly, so I expect there could be trouble down
the road in searching for libraries of things, etc. But at least both
compilers will execute and compile code without interfering with each other.

Hope this helps others.....
