Compatibility between versions 11.23 and 11.31

[Miguel Silva Rentes]

Hi everyone!

I created an application in a HP-UX 11.23 server and was compiled with aCC A.06.13. Can I use this process in a HP-UX 11.31 server?

I haven't used any optimization flags when compiling my application (like +DO11.23) so I think I can use this application in a HP-UX 11.31 server.

Can I also upgrade HP-UX from 11.23 to 11.31 in this server and use my application?

Best regards,

Miguel Rentes

Yes, provided it is not kernel intrusive and is well behaved.

These aren't optimization flags but are OS version specific flags.

Hi Dennis,

Ok, but you agree that these kind of flags makes an application incompatible between different versions of HP-UX, rigth?

Yes, if you compiled with +DO11.31 and tried to run it on 11.23, there could be problems.

Ok, that's what I thought too.

If I want to upgrade a server to the latest HP-UX version, do I have to buy the HP-UX dvd's or is it just a matter of downloading an "update bundle" of patches and/or software?

Thanks,

I'm not sure if a support contract will get you the DVDs.

OK, thank you very much for you help.

A support contract for the HP C/aC++ compiler will get you new DVDs or you can download a new one with the SUM program.
I would guess it is the same for HP-UX:
From the main ITRC page you can get to SUM:
