Description Carlo 2019-01-24 18:30:23 UTC
I have successfully compiled perl on HPPA2
2019-01-24 =dev-lang/perl-5.26.1-r2 ] - success - @2.29.1/7.3.0
with gcc v7.3.0, binutils 2.29

the process has completed successfully but perl shows weird behavior

perl -V

reports: did not return a true value.
BEGIN failed--compilation aborted.


perl -e "print qq(@INC)" reports

/usr/lib/perl5/vendor_perl/5.26.1/hppa2.0-linux /usr/lib/perl5/vendor_perl/5.26.1 


look at this simple script

use strict;

when executed, perl reports this did not return a true value at ./ line 3.
BEGIN failed--compilation aborted at ./ line 3.

Comment 1 Jeroen Roovers gentoo-dev 2019-01-24 19:28:24 UTC
Can't confirm that this is architecture specific. I had this version running fine for nearly a year.
Comment 2 Jeroen Roovers gentoo-dev 2019-01-24 19:30:40 UTC
I had 5.26.1-r2 working between February and April 2018.

emerge info

attaching the emerge --info for hppa

This report I about perl v5.26.1-r2 
I have also tried v5.26.2: it has the same problem
Comment 4 Carlo 2019-01-24 19:38:28 UTC
yes, it works OK on { ppc, x86 } but not on hppa2
I have update all systems in parallel, virtually with the same commands and procedures.

anyway, I need a way to investigate *what* goes wrong.
I cannot understand the error reported by perl

it seems it's unable to handle "use strict;", which is weird.

how can I investigate it?
Comment 5 Carlo 2019-01-24 19:49:50 UTC
I am reading this
Comment 6 Kent Fredric (IRC: kent\n) gentoo-dev 2019-01-25 10:18:37 UTC
Your output listing of @INC seems malformed, specifically, 2 entries on one line is "odd", and I can't tell if its some side effect of how you processed it, or if there's potentially something wrong in your @INC.

To clarify, please report:

 /usr/bin/perl -e 'printf qq[< %s >\n], $_ for @INC'


Also, please attach a copy of the file(s) reported by running this command:

 /usr/bin/perl -e '-e "$_/" && printf qq[%s/\n], $_ for @INC'

trying to piece together what happened before perl gone insane, I had issued the following command

so trying to upgrade perl to dev-lang/perl-5.26.2, it then successfully emerged


then something went bad and =perl-5.26.1-r2 and/or something related to Perl got damaged and stop working; before the emerge --update perl v5.26.1-r2 was working.

output of perl -V

I did run perl-cleaner --reallyall at some point, but it didn't help, the procedure did neither complete

so I wanted to try a wild approach

equery belongs /usr/lib/perl5/vendor_perl/
didn't report any package belonging the file

whereas equery belongs /usr/lib/perl5/5.26.1/hppa2.0-linux/
reported the file belonging to =dev-lang/perl-5.26.1-r2

anyway, I wiped both

rm /usr/lib/perl5/5.26.1/hppa2.0-linux/
rm /usr/lib/perl5/vendor_perl/

then I cleaned other things
emerge --ask --unmerge 'perl-core/*' 'virtual/perl-*'

and finally, I re-emerged perl
emerge =dev-lang/perl-5.26.1-r2

Surprisingly now perl "seems" (not really sure) of being working.

Attached the log of "perl -V"

I am going to run perl-cleaner again.
Comment 12 Carlo 2019-01-29 14:26:44 UTC
so after having a working perl 6.26.1, I launched 

emerge-log =dev-lang/perl-5.26.2

and yet again perl is broken

perl -V did not return a true value at /usr/lib/perl5/5.26.2/hppa2.0-linux/ line 9.
BEGIN failed--compilation aborted at /usr/lib/perl5/5.26.2/hppa2.0-linux/ line 9.
Compilation failed in require.
BEGIN failed--compilation aborted.
Comment 13 Carlo 2019-01-29 23:35:40 UTC
it seems, but I am not 100% sure about this, that something in dev-lang/perl-5.26.1 makes the system dirty.

So I wanted to try a radical approach this time

emerge --unmerge dev-lang/perl
emerge --deselect  perl-core/File-Temp
rm -r /usr/lib/perl5/vendor_perl  <--- other packages are broken now
emerge =dev-lang/perl-5.26.2      
perl-cleaner --reallyall          <--- but this should fix them

Now I am sure that things have emerged with perl-5.26.2
all the initial problems are gone now ...

... I hope once and forever :)

Comment 14 Kent Fredric (IRC: kent\n) gentoo-dev 2019-02-01 20:15:05 UTC
(In reply to Carlo from comment #7)

> /usr/bin/perl -e '-e "$_/" && printf qq[%s/\n], $_ for
> @INC'
> /usr/lib/perl5/vendor_perl/
> /usr/lib/perl5/5.26.1/hppa2.0-linux/

This is the smoking gun here. Combined with the fact the top "" was an empty file.

I'm not sure *where* that file came from, but it should not exist, it should only exist in the versioned dir. ( /usr/lib/perl5/5.26.1/hppa2.0-linux/ )

So if the reason for a existing somewhere else can be identified, then we can solve the bug.
