Compatible build machine for 10.20, 11.00 700 and 800 series

[Alex Smith_1]

My company currently builds on a 9000/778 workstation. From this single build we support 10.20 (700/800 series), and 11.00 (32/64bit)(800 series). We are hoping to move to a beefier machine, but I have heard that you cannot build on an 800 series machine if you want to run on a 700 series. I have looked for a document to back this up but I can't find one. Can anyone confirm this, and as an added bonus can you direct me to an official doc.
Thanks

Hi Alex,

If you use the aC++ compiler (B3913DB) for c and c++ and compile/link with the +DAportable
flag then you can produce executables that will run on the vast majority of workstations and servers in both 10.20 and 11x. You can man aCC for details or download the Ansi C++ documentation for details. Any machine that uses PA-RISC 1.1 and above will work. I've attached a list of models and their PA-RISC levels that is supplied with the aCC package. Only a very few old guys are PA-RISC 1.0 and thus are imcompatible.

For what it worth, yes, I've actually tried this. e.g. code compiled on a K580 will execute on a 712/64 if the +DAportable flag is asserted.

Regards, Clay
