It's actually an issue with libprotobuf... I've been trying to track
down and solve this appropriately upstream. There is an protobuf bug...

http://code.google.com/p/protobuf/issues/detail?id=188

Which I believe is related.

For the purposes of ubuntu, I'm just going to add a patch to explicitly
add in -lpthread ... and I'll figure out a real solution upstream.

I'll also turn on verbose builds...

This bug was fixed in the package protobuf - 2.3.0-4ubuntu2

fixed protobuf. now drizzle fails with:

  CXXLD drizzled/drizzled

Piddle. I shall investigate.

With the new protobuf packages, drizzle builds from source for me on my natty box... I'll try next in the context of a debuild...

Is there anything the ubuntu builders are injecting into how things are built? I'll also push up a new rev with V=1 turned on.

no, the builders do not inject anything, but we did turn on ld --as-needed in natty.

my assumption is that drizzled/libtemporal.la doesn't mention the need of the pcre library. I'll see if that is the case. as an alternative, the drizzled link could explicitely mention -lpcre.

This bug was fixed in the package drizzle - 2010.12.05-0ubuntu3

I tried changing how we specify the libpcre link on my natty test box
and it worked - I've just pushed a new package to see if it makes it all
the way through.
