Thread-support in perl-native often breaks libintl-perl

Thread-support in perl-native often breaks libintl-perl

[Martin Dietze]

Hi,

 on most platforms thread support is turned off for the
cross-compiled perl packages. However it is always turned 
on in the perl-native package. Since libraries like
libintl-perl depend on perl-native since they include their
headers from staging/[my-platform]-linux/lib/perl5 we get
an inconsistent configuration: the shared lib gettext_xs.so
is cross-compiled with headers with thread support turned
on while the actual (non-native) perl has it turned off. In
the end libintl-perl will not work:

| /var/bin/perl: relocation error: /var/lib/perl5/auto/Locale/gettext_xs/gettext_xs.so: undefined symbol: Perl_Gthr_key_ptr

Removing the `-Dusethreads' from the perl-native recipe solves
this problem, but will it cause problems for others?

BTW, where is bugs.openembedded.org - it has not been up for a 
longer while...

Cheers,

Martin

For sh4 I turned on threading for perl which is probably why I didn't
have this issue. I can't remember if I turned it on because of this
issue or if I needed it for somethings else. It probably doesn't
matter much anymore for my situation because I've since rewrote the
perl management application I was working on in C, so I only use perl
a lot of simpler things now.

I agree that we probably need to make perl and perl-native agree on
this. If everything appears to be ok with it turned off in
perl-native then I'd be fine with that (and would turn it of for the
sh4 perl as well.)

  Maybe make that some "global" config option, and have it on by
default after all (after bit of QA of course)? These days, lack of
multithreadedness is a defect, and even while it's Perl, maybe it
shouldn't be crippled such? ;-)  (No, I don't volunteer to do QA on it
;-) ).
