This is the downside people in this thread are
complaining about:
compiling 32-bit programs on a 64-bit Ubuntu install is now slightly
more difficult. However, Wine is currently the _only_ piece of
software I've encountered that needs to be built for both arches on
the same machine in order to be usable. We are beautiful special
snowflakes here: Wine developers who aren't using the build daemons is
about the extent of the current use case.
<snip>
I'm beginning to have memories of what happened when we removed gcc
from the default install. Setting up a 32-bit chroot for building
Wine should not be complicated -- I'll present a script to make it
even easier soon. You can build in a single command and even use
things like ccache and the like to speed it up.
to summarize:
ubuntu doesn't do anything to support developers
as it implies using ubuntu build daemons, not developers' machine
(and all the relevant environment)
as it implies to use chroot even on a multi lib arch => multi arch
is then for users, not developers
bye bye ubuntu then
for the sake of record (I won't even dare to send it to wine-patches) a
workaround ubuntu recvmsg breakage in order to get ptrace API to be
usable on 12.04
