Description thssld 2023-09-10 06:57:47 UTC

Some installed files of dev-lang/perl contains the kernel version of the building host. This behavior affects bin-pkg level reproducibility.

Here is the list of affected files:

> /usr/lib64/perl5/5.36/x86_64-linux/CORE/config.h
> /usr/lib64/perl5/5.36/x86_64-linux/Config.pm
> /usr/lib64/perl5/5.36/x86_64-linux/Config_heavy.pl
> /usr/lib64/perl5/5.36/x86_64-linux/Errno.pm

It seems that following lines caused this behavior:

> config_h.SH
>   49  * Target system     : $myuname
> 1412 #define OSVERS "$osvers"                /**/

> configpm
> 1236 osvers: 982

> Configure
> 24494 # Target system     : $myuname
> 25465 osvers='$osvers'

> ext/Errno/Errno_pm.PL
> 300 "$archname-$Config{'osvers'}" or
> 301         die "Errno architecture ($archname-$Config{'osvers'}) does not match executable architecture...

Thanks for filing this & looking into this class of problem.

This has caused some other interesting problems before, too.

sorry, I pressed submit too early: in the other case, it seems/seemed to be a problem in itself in Perl, but it's still notable: https://github.com/Perl/perl5/issues/21135.
