VAX C compiler

How can I get a copy of the VAX C compliler version 3.2?

Send some e-mail to sms@antinode-org (more or
less). It's on the March 1993 ConDist,
apparently.

I have V3.1, too, if you're looking for
antiques.

Why? (DEC C is generally considered an
improvement.)

Dave,

What is the ovms version you have? Fyi, this VAX C compiler was not included in any Y2K investigations, an it has not been tested on any recent OpenVMS/VAX releases; the last supported VAX/OpenVMS version for this VAX C V3.2 was VAX/OpenVMS V5.x.

We are running some old shop applications on Microvax's running 6.2 The compiler we had was 3.2. I have asked the developer to use the dec c compiler but he insists he needs the vax c compiler.

If one were feeling cynical, one might be
tempted to suspect that he didn't want to
have to clean up his code. If one were
feeling cynical, that is.

There are versions of DEC C which run just fine on VMS V6.2 and it is worth the effort to clean up the code so it complies without warnings. This will often find bugs before the users do. DEC C does have a VAXC compatability mode but I would not recommend it was used.

If you have an alpha on which you run the self extracting exe in
ftp://ftp.compaq.com/pub/products/C-CXX/openvms/c/

then you may get a DEC C kit you can install.

All Alpha, I believe. (Kit contents, not
just the Zip-SFX executable target.)

I agree with Ian, migrating to to the DEC C compiler is well worth the effort.

I found turning up the diagnostics to LEVEL=4 really helped to uncover dormant bugs in our code. Very handy indeed.
