Itainium - RISC HPUX 11i v1 C Code question

[James M. Dunn]

A little history first.

I'm current running an application that has some old C code on it, this code works on 11i v1. The server is RISC and the sorce code is no longer available (vendor has lost it) in any case I need to buy a new server that can run HPUX 11i v1, I'd like to buy an Itanium server and run HPUX 11i v1.

Will C code that was compiled on RISC HPUX 11i v1 run on an Itanium 11i v1?

Any thoughts?

Hi James:

Well, first, Itanium platforms do not run 11iv1 (11.11). They ONLY run 11.23 (11iv2) or 11.31 (11iv3).

That said, yes, your PA-RISC C-code (if well-bahanved = not kernel intrusive) will run on an Itanium server using ARIES:

Thanks FOR YELLING!

and the INFO you Provided!

James, if you think you still need a server that can run 11.11 (11iv1), have a look at the current HP9000 family:

Anyway, an Integrity with aries could be a solution too.

Hi (again) James:

> james Thanks FOR YELLING!

...well, the "ONLY" was for meant for emphasis...and the "ARIES" case was to signify an acronym (which it is).

:-))

Umm thanks for the link.

This C code is used to comunicate with a HP Non Stop server. The code has been working on 10.20, 11.0, 11i v1, my wish is to move to Itanium and get off the RP7420 its sitting on now.

since I dont know if it will work on a Itanuim without testing it on a server, I thought I would ask the forum about portability of C code from RISC to Itanium.

Unfortunately for me I worded the question wrong and I'm receiving answers in CAP's.

James,

Generally code portability is pretty good, but without knowing the specifics of your application it's difficult to say.

I'd start by reviewing the material in the Software Transition Kit (STK)

http://h21007.www2.hp.com/portal/site/dspp/menuitem.863c3e4cbcdc3f3515b49c108973a801/?ciid=bdbdf58743935110VgnVCM100000275d6e10RCRD

And make sure you look at the binaryScan tool which might help qualify how easy/hard the transition will be:

... and then I read your inital post again and noted that you've not got the source code...

In that situation ARIES (sorry about the CAPSQ!) is the only way to go.

huh the download page is blank,

darn it.

I sent a message to HP, they will contact me in 3 days, time to open a ticket i guess.

Well, some Itaniums ran 11i v1.5 (11.20) and 11i v1.6 (11.22), but neither of those are supported any longer :) Regardless, it is indeed the case that the HP-UX 11i v1 Operating System/kernel will not run on an Itanium system.

As already pointed-out, one can execute HP-UX PA-RISC binaries on HP-UX Integrity (aka Itanium) systems. Also, I suspect that if the code has been on 10.20, 11.0 and 11.11 the source code would likely port to HP-UX Integrity rather easily - likely as not just a simple matter of recompilation.

I take that this output means its portable...

[Duncan Edmonstone]

Afraid I know where the tool is, but not how to interperet its output.

I note that the binary you are checking is a shared lib... do you call that shared lib from other code of yours that you intend to port to Itanium?

The reason I ask is that what ARIES will *not* allow you to do is call a PA-RISC shared library from a IA64 executable. The executable would have to stay on PA-RISC as well.

>Duncan: what ARIES will *not* allow you to do is call a PA-RISC shared library from a IA64 executable. The executable would have to stay on PA-RISC as well.

What Duncan means is that the whole application would have to be left as-is and the whole thing copied to your new Integrity box.
