Hi,
I'm looking for an ADA compiler for my PC (I'm more interested in the
95 version but the 83 one will be a good beginning for me!)
thanXXX.

It seems appropriate for me to answer this, in view of the thread about
"GNAT Free?" that has recently appeared :-)

Yes indeed Eric, there is a freely available Ada 95 compiler, GNAT. This is a
full featured Ada 95 compiler (indeed GNAT is so far the only available Ada 95
compiler that implements the core and all the optional annexes(*)). You can
download a version from many FTP sites, including ftp directories pub/gnat at
cs.nyu.edu. Many PC versions are available, for various operating systems,
including Linux, OS/2, Win95, and WIN/NT.

There is definitely no point in looking at Ada 83 at this point (and
interestingly, there never was a practical freely available version of
Ada 83, one of the great pities in retrospect!)

(*) I am looking forward to the point in time when we can no longer say this.
It would be really nice to see the other Ada vendors implement all the
optional annexes. In particular, it would be really nice to see other
implementations of the distributed systems annex. I think this is a very
exciting feature of Ada 95 with tremendous potential, but the full potential
is not realized unless all Ada 95 compilers implement this feature. In
particular, the distribution annex offers a path for convenient integration
of Ada programs across multiple machines using different Ada compilers.

Does it really offer that kind of interoprability? According to my reading of
annex E it does not.

But given that no-one else has implemented it yet, there does appear to be
time to create a standard such that it will work across compilers. Is this a
possiblity? If future vendors use GLADE as a base, it doesn't seem like it
would be too tough to accomplish.

Business is business. I desperately needed one of the ASIS annexes
that, as far as I know, no vendor implemented. At least no one knew
of any vendor who did. Rational, in essence told me that it would be
too difficult for the potential customer base, which Rational interpreted
as "Who has asked us for this." Answer: No one, you are the first.
Therefore there is no market. Now that determination of the "market
needs" can certainly be debated, the bottom line is the reason some of
the annexes don't get implemented is because someone has decided there
it isn't worth it.

Yes, of course this is most certainly true. And particularly in the case of
Annex E, the implementation effort is significant (we estimate that we have
spent something like 10-15 person years of effort in implementing Annex E).

By the way, you might want to communicate your ASIS needs to ACT. As far as
I know, we have implemented pretty much all of ASIS at this stage, certainly
we have implemented all annexes used by our customer base as far as I know.

Hi,
you could download OA for NT from
http://www.aonix.com/Products/CSDS/ada.download.html
If you want to receive a CDROM version of this compiler send me your
address.

Look at gnat on Linux :-)
