Tru64 UNIX 4.0B application's executables compatible on 5.1A?

[Lee Eng Huat]

Hi,

A defense-related customer has a graphic application running on AS400 /Tru64 UNIX 4.0B.

Questions
=========
1) Can the same application's executables (no source codes) compatible and able to run on DS15 or DS25 /Tru64 UNIX 5.1A?
2) If not, please advise what needs to be done or options available in order to port this application from Tru64 UNIX 4.0B to 5.1A?


Thanks & best regards,

EH

There's no way to know for sure without trying it, but unless weird graphics H/W or drivers are involved chances are pretty good it will work.

Here are some places you might find difficulty:

- non-standard graphics device/driver
- 3rd party graphics libraries (you may be able to copy .so files directly)

If you don't have source code you're kinda stuck if you run into a problem. I've never hear of any sort of binary translator for this kind of thing.
