On 2010-11-28, Austin English contacted us, stating that he's working on
porting [Wine](http://winehq.org/) to the GNU/Hurd.
It is not yet clear how difficult this is going to be, what sort of
requirements Wine has: only libc / POSIX / etc., or if there are
*advanced* things like [[system_call]] trapping involved, too.
[[Samuel|samuelthibault]] suspects that *there's some need for LDT table
allocation. There is kernel support for this,* however.
IRC, freenode, #hurd, 2011-08-11
< arethusa> I've been trying to make Wine work inside a Debian GNU/Hurd VM,
and to that end, I've successfully compiled the latest sources from Git
after installing the libc (devel) packages from experimental and
personally patching Wine with http://pastebin.com/rg6dx09G
[[rg6dx09G.patch]]
< arethusa> my question is, when trying to launch Wine, I'm seeing "wine
client error:0: sendmsg: (os/kern) invalid address" from the client side,
whereas the wineserver seems to be starting and running correctly, how
could I debug this issue further? using rpctrace doesn't seem to help, as
the trace just hangs when run on the Wine loader instead of yielding
insight
< kilobug> arethusa: isn't there a wine debuguer that can start a gdb when
wine encounters an error or something like that ?
< arethusa> it's too early for that
< kilobug> or least give you a full traceback of the wine code where the
error occur ?
< arethusa> the error is happening during initial connect to the
wineserver, in dlls/ntdll/server.c
< arethusa> but that doesn't help me figure out why sendmsg would error out
in this way
< arethusa>
http://source.winehq.org/git/wine.git/blob/HEAD:/dlls/ntdll/server.c#l361
< azeem_> arethusa: probably some of the msghdr entries are not supported
by the Hurd's glib
< azeem_> c
< pinotree> haha, socket credentials, which we don't support yet
< azeem_> yep
< pinotree> youpi: ↑ another case ;)
< azeem_> arethusa: just implement those and it should work
< kilobug> in pflocal ? or glibc ?
< pinotree> pflocal
< arethusa> azeem_: hmm, okay, thanks
< pinotree> arethusa: their lack is a known issue, and makes things like
dbus and gamin not work
< arethusa> it's
https://www.gnu.org/software/hurd/open_issues/sendmsg_scm_creds.html and
related links I assume?
[[sendmsg_scm_creds]]
< youpi> yes
< pinotree> (but that patch is lame)
