target PA-RISC using itanium GNU compiler?

[simons_4]

is there a way to create PA-RISC executables using the GNU compiler on HP-UX 11.23?

[Robert-Jan Goossens]

Hi Simons,

No.

HP provides forward binary compatibility between the versions of HP-UX 11i on the same architecture. This means that:

HP-UX 11i v1.5 applications run unmodified on HP-UX 11i v1.6 and on HP-UX 11i v2.

HP-UX 11i v1.6 applications run unmodified on HP-UX 11i v2.

HP-UX 11i v2 September 2004 and later releases are engineered to provide application binary compatibility between HP-UX 11i v1 (B.11.11) and earlier releases of HP-UX 11i v2.

Hi,

does this mean I should use the HP Compile??

regards

Simon

[Robert-Jan Goossens]

Sorry I should have added the opposite is possible, compiling on 11iV1(11.11) and running on 11iV2(11.23). There is no downwards compatibility.

If you're asking about "cross-compiler" (generate native code for PA on IA platform, or visa-versa)....

I don't think there are any available, GNU or otherwise.

I suppose in _theory_ one might be able to setup a GNU cross-compile environment. In _theory_ one might be able to setup an SDK (?) with a PA-RISC HP compiler.

Not certain it is worth the likely effort. The resulting binaries have to be tested, and while they can indeed be run under Aries, and it is indeed supposed to be that Aries faithfully emulates PA-RISC, I'd not rely solely on it to find timing-related issues in code that will be running natively on PA-RISC systems.

If there is anything on "supported" cross-compilation from Itanium to PA-RISC it would probably be in the DSPP somewhere - IIRC one starts at http://devresource.hp.com/

HP compilers support this SDK concept:

This is not supported and you are on your own.
