Re: 64bit support news

[Samuel Thibault]

Hello,

Now is probably a good time to give an update on the 64bit front.

Thanks to Michael Tokarev's fast buildd boxes, we have finished building
the Debian packages that we had at hand.

There are 3809 packages waiting for some failing dependencies, to be
compared with the 3086 packages that have that status for the 32bit
port. The current missing big contenders, as seen on

https://people.debian.org/~sthibault/hurd-amd64/graph-top.txt

are openmpi, gst-plugins-bad1.0, and webkit2gtk.
The cudf failure will be fixed by Guy's work on moving pthread symbols
to libc.so, and java is a hopeless thing.

I also ran a script that checks for packages that fail on 64bit but
doesn't on 32bit. Quite a few of them are related to dumb issues (symbol
list and such), but a few of them are worth noticing:

https://buildd.debian.org/libtext-bidi-perl
https://buildd.debian.org/armci-mpi
https://buildd.debian.org/genimage
https://buildd.debian.org/ifupdown-ng
https://buildd.debian.org/libepoxy
https://buildd.debian.org/libzstd
https://buildd.debian.org/kquickcharts
https://buildd.debian.org/pristine-lfs
https://buildd.debian.org/golang-petname
https://buildd.debian.org/jimtcl
https://buildd.debian.org/pixman
https://buildd.debian.org/contextfree
https://buildd.debian.org/powerman
https://buildd.debian.org/ruby-strptime
https://buildd.debian.org/autogen
https://buildd.debian.org/jpeg-xl

Most of these have odd testsuite issues. These are probably worth
investigating, because they are most probably issues in our 64bit
port. Possibly quite a few of them are just symptoms of the same common
bug.

Help welcome on investigating them!
