           Summary: FreeBSD: -pthread is handled incompletely
           Product: gcc
           Version: 4.5.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: avg@icyb.net.ua

On recent (and maintained) versions of FreeBSD it is required that shared
libraries using pthread functions are linked to libpthread.  This was not the
case in older and now unsupported versions of the OS.
So, currently GCC on FreeBSD expands -pthread option to -lpthread only when
target is a final binary.  When compilation target is a shared library -pthread
is ignored.
This needs to be fixed in -pthread specifications for FreeBSD.

And, in fact, I did that a (short?) while ago:
http://thread.gmane.org/gmane.comp.gcc.patches/217482/focus=217484
But it seems that nobody has picked it so far.
Perhaps I am the one to blame for that given the incorrect attachments.

If you do not receive a response to a patch that you have submitted within two
weeks or so, it may be a good idea to chase it by sending a follow-up email to
the same list(s). Patches can occasionally fall through the cracks. Please be
sure to include a brief summary of the patch and the URL of the entry in the
mailing list archive of the original submission.

If you do not have write access and a patch of yours has been approved, but not
committed, please advise the approver of that fact. You may want to point out
lack of write access in your initial submission, too.

And point 6 here:

I'm doing the necessary regression testing and will report the patch
with a proper ChangeLog entry later this week.

(I actually was the one encouraging Andriy to post the patch and file
a Bugzilla, just missed the latter.)

I for one would love to have this (and PR52277) but I cannot commit the amount
of time/work needed to make this work.

Pretty please, could someone implement it? Marek, Paolo, Google guys?

Jason, do we want this?

Following Clang or in some other way?

--- Comment #8 from Philip Prindeville <philipp_subx@redfish-solutions.com> ---
(In reply to joseph@codesourcery.com from comment #4)

What about using pragmas to describe the new format specifier?

Good point, since I had committed this for GCC 4.6 (and later) and
also GCC 4.5.

Closing as fixed.  And thanks, Andriy!
