That's odd. s_lock has been declared the same way right along in our
code; I didn't change it. Can you see what's changed to cause a
conflict where there was none before?

This maybe Matt Dillon's recent commit to FBSD then. Either way, it's
a problem on -STABLE 4.2 of FreeBSD.

Other things that may be an issue:

1) BINUTILS 2.10.1
2) OPENSSL 0.9.6

both just MFC'd into FreeBSD recently, but I believe we built until
tonite.

I can make you an account on the box if you'd like....

My signifigant other just installed a fresh copy of 4.2 last night,
unfortunetly the poor box is only a 233mhz, it'll be a while before
we build -stable on it.

However I'm confident I can have a fix within a couple of days.

I just remebered my laptop in the other room, it's a pretty recent 4.2.

I'll give it shot.

Yes, it's possible to forget about a computer...

Ick. Seems like the relevant question is not so much "why did it break"
as "how did it ever manage to work"?

I have no problem with renaming our s_lock, if that's what it takes,
but I'm curious to know why there is a problem now and not before.
We've called that routine s_lock for a *long* time, so it seems
like there must be some factor involved that I don't see just yet...

Yeah, but don't tell me you were running on a non-TAS platform...
that stuff didn't work...

The configure stuff used tas/dummy.s, so I'm not sure....

Grr, couldn't find the original message. I think you thought
you solved your problem with building on FreeBSD, however I
think you just forgot to compile with perl support enabled.

When I compiled with perl support it broke. This isn't a
postgresql bug, nor a FreeBSD bug although the fault lies
mostly with FreeBSD for polluting the C namespace a _lot_
when sys/mount.h is included.

What happens is the the perl code brings in perl.h which brings
in sys/mount.h, sys/mount.h includes sys/lock.h because our
kernel structure "mount" has a VFS lock in it, VFS locks happen
to contain spinlocks (simplelocks) and one of our our functions
to manipulate the simplelocks is called s_lock(). This causes
a namespace conflict which causes the compile error.

Anyhow, to address the problem I've removed struct mount from
userland visibility in both FreeBSD 5.x (current) and FreeBSD 4.x
(stable).

Things should work now but let me know if you have any other
problems.

And thanks for pointing it out and offering to help track it
down.

here's the patch if you don't want to cvsup your machine all the
way.

Actually, perl support was included, and Tom's fix in the
cvs DID fix it, but fixing FreeBSD doesn't hurt. Here is
what I've been configuring with:

./configure --prefix=/home/ler/pg-test --enable-syslog \
--with-CXX --with-perl --enable-multibyte --enable-cassert \
--with-openssl \
--with-includes="/usr/local/include/tcl8.3 /usr/local/include/tk8.3" \

That might fix things on your box, but we can hardly rely on it as an
answer for everyone running FreeBSD :-(.

Anyway, I've already worked around the problem by rearranging the PG
headers so that plperl doesn't need to import s_lock.h ...

Well I didn't say it was completely our fault, it's just that we
try pretty hard not to let those types of structs leak into userland
and for us to "steal" something called s_lock from userland, well
that's no good. :)

Actually, Alfred is a FreeBSD committer, and committed it

It's for ALL at FreeBSD 4-STABLE as of today.
