Cannot install on AIX 7.2

[thomasseeling-ibm]

Mojolicous-9.41.tar.gz contains extended headers which confuse cpan on AIX 7.2.

I'd be happy to fix this if someone could finally tell me which env vars to set during make dist on macOS. So far nobody has been able to unfortunately.

Can you install and use gnu-tar?

@s1037989 the tar arguments listed in your slop script are to be specified when creating the archive, not when unpacking it.

If you're not gonna bother writing it, and you're not gonna bother reading it, maybe don't bother posting it either?

Can you instruct tar to omit PaxHeaders when creating the archive? I cannot install additional tools.

Use tar --format=ustar and maybe even the additional environment variables to avoid MacOS specialties in the archive.

set the environment variable COPYFILE_DISABLE=1 before invoking tar or make.

Although the AIX man page for tar refers to pax format only when using -c archive create switch I found out that it also works for extracting, so for manual installation the following snippet using --format=pax works. The man page says this requires AIX 7.3.1 though. YMMV.

gzip -cd "${module}".tar.gz | tar -x --format=pax -f -
cd "${moduledir}"
perl Makefile.PL
...

But cpan would still fail.

Of course it's not that easy, i've had these env variables for many years, they just stopped working one or two macOS updates ago:

export COPYFILE_DISABLE=1
export COPY_EXTENDED_ATTRIBUTES_DISABLE=1

What i need is the newer version of this for my .bashrc.

I work around this by having the gnu tar on macOS.

People have been arguing about this for years: https://superuser.com/q/318809/12972

Just for cross-linking, the post on /r/perl.

Just for cross-linking, the post on /r/perl.

The link to that other discussion at superuser.com does not exactly match my problem - MacOS adds some attributes and some other tar complains about unknown extended attributes (since I also compile for RHEL 8, 9 and 10 I've seen those error messages too, but fortunately the build can ignore that successfully). My problem was complete failure to run perl Makefile.PL. I tried shortly to understand the problem with perl -d Makefile.PL but ran out of time and patience.

This is probably fixed wit the release of 9.42.
