I think Vince Castellano at OC Systems has ported it to Linux, which I
was hoping to re-port to the SGI (but lack the time at the moment).
You might want to write to Vince at gvc@ocsystems.com 

Please, don't everybody all at once write to Vince...I'm posting this
publicly because I felt this information (that c2ada was ported to
Linux) is a worthwhile public comment.

c2ada (cbfe) on Linux? And: Ada graphics lib?

[Dirk Dickmanns]

Hello,

first of all many thanks to Randy Hudson and Mitch Gart of Intermetrics
for c2ada -- really helpful.

Question: has anyone bothered to compile it for Linux?  Some headers
declare functions conflicting with standard libraries.  Comments show
this might be due to some funny features of the C system used,
example:

rgh: /* why don't these functions have prototypes in <stdio.h> ? */

After simply deleting the offending function declarations, other
things came up :-(  Anyone in net-land taken care of that? Or do I have
to do it myself?

Another question: My poking around for graphics stuff in Ada wasn't
quite successful.  Any hints?  Topics: homogeneous coordinates,
quaternions, generally linear algebra, modeling, rendering,
bindings... ???

Please mail and ask for summary, if interested.

Dirk

commercial Un*x bugs ;-) Sorry, pun against some posts in the Unix
haters thread included...  Up to now, my Linux box isn't less
professional than the SUN which I use here at work.  Linux _is_ great.)

See, I said that Linux was not a typical Unix system :-)
In fact Linux is yet another reminder that quality of sotware is
not necessarily directly proportional to cost!
What is interesting too is the performance of Linux, even on a modest
PC, it can give a Sun work station user quite a surprise in this
regard -- I pushed to get Linux-PC' for our students here at NYU,
and that's where I see this comparison made.

Linux is one of the more heavily used ports of GNAT. Not a lot of
commercial users yet, not surprisingly, but judging from email we
receive, a very widely used port.

Sadly enough! It would deserve being it.

It was not your comment (I think, but I really don't know and won't
look it up), but someone picked on it as a system designed by some
student <shudder>. I can only add: What a student!

Yeah, and it is living software: choose one of a hundred versions with
the fewest bugs hurting you and be happy.  Mickeysoft allows you to
choose between 95 Breaking Windows (tm)...

Agreed, same experiences over here.  My P5-133 at home runs as fast or
faster than all our SUNs but the Ultras.  And those PC's are cheap (no
start of WS vs. PC flame war intended ;-).

I have, but I can't make it publicly available until the
first of next month because I'm overseas from my machine
until then.  At that time I expect to attach it to
the Free X/Ada WWW page.  Mail me if you want e-mail notification
when it's available, or else 'watch this space'.
