Perl machine architecture vs real machine architecture

Ovid Saveluc_1 — Thu, 15 Apr 2004 00:47:36 GMT

Hi,

I have a version of Perl 5.6.1 for PA-RISC1.1 (according to perl -v) running on an N4000-55 machine (which is PA-RISC2.0).
As far as I know one may encounter problems when running code compiled/ built on one PA-RISC version on another PA-RISC spec machine.

Is there a known exception to this for perl ?

Thanks,
Ovid.

no. and the exception is only one way

1.1 compiled code will run fine on 2.0 or 2.0w, but not vise versa

the problem with perl is that needs the same architecture when _extending_ with XS modules (XS modules are based on C code and require the same compiler that Perl was built with for smooth binding)

So, if you plan to move ahead, and install XS modules from the new architecture (Tk, DBI, DBD::Oracle, ...), please do yourself a favour and fetch the perl binary built on that architecture and OS version

Recent builds always available oy HP ITRC site pages can be found at

Perl compiled for PA 2.0 might run faster on a PA-2.0 machine than a PA 1.1 binary.
