Run C program compiled on OSF 3.2 on OSF 5.1

[Hermans_4]

Some years ago I had a workstation running OSF 3.2. Now I considder to buy a machine with
OSF 5.1 . I have several programs written in C , which where running on the OSF 3.2.
Can I run this programs without recompiling on the OSF 5.1?

I had some troubles on precompiled sw between OSF 4.0 and 5.1
If they were statically linked you'll surely get some core-dump && segfault, but it could not happen if you use very simple software linked only to libc.

Better recompile. cc Options should be the same.
Peace, R.

Alpha architecture and os changed during time, so it is recommended to recompile your programs. If you have compiled with shared libs give it a try (but possibly it will fail).

Btw. 5.1 is out of support, try the version 5.1B-1 which is fully supported until end of the "Alpha"-area.
