This page attempts to track the current issues of the Debian/m68k Linux port. Mailing list is at firstname.lastname@example.org and more information can be found in this Wiki under M68k and M68k/Porting.
Read M68k/Installing for a list of all possible ways.
Quick start: Get an Aranym/Quick image (sid from April 2012) and update it. Once you have it running, grab a /var/cache/pbuilder/base.cow at M68k/Cowbuilder or run “cowbuilder --create” with the appropriate options yourself or install sbuild.
Wouter is working to get d-i into shape again, see M68k/Installing.
Some packages are in debian-ports.org unreleased, not in unstable, because they need m68k-local patches. For some, this is because maintainers keep unstable frozen during the squeeze/testing freeze in order to be able to upload fixes via unstable. For some, this is a collection of patches or workarounds that are not, or will not be, included in the proper Debian packages. Once installed, however, it’s fine to work from unstable only (unless you want to hack the packages from unreleased).
We’re using gcc-4.6 for almost everything now. The eglibc source package manually selects gcc-4.4.
Works, has TLS backport. gcj-4.4 should work.
Not ported. Has TLS upstream. Will not be ported, we’ll be switching from gcc-4.4 directly to gcc-4.6 when the time is right; wheezy will not be released with gcc-4.5 anyway.
Ported, default compiler. Contains patches for atomic builtins.
gcj-4.6 works nowadays; no special patches yet.
gnat-4.6 works, as patched in unreleased.
* ICE in cselib_record_set, at cselib.c:2158 or thereabouts (adding -O1 helps)
* ICE in fixup_reorder_chain, at cfglayout.c:880 or thereabouts (adding -O0 seems to help) (fixed in gcc-4.6 4.6.3-14+m68k.3)
Builds. Not really tested/used.
Does not work.
We have Linux 3.2 unchanged from Debian wheezy/sid.
Right now, 3.2.0-4 (ABI), 3.2.35-2 (package) is available. The lowest version you really want is 3.2.32-1+m68k.1 (unreleased) or 3.2.35-1 (unstable).
Amiga: Ingo says the stock kernels (3.2.0-4-amiga) work for him on several machines. Cyberstorm Mk1 & Blizzard 060 SCSI support seems to be missing.
Atari: The stock kernels work on ARAnyM, but lack Ethernet drivers on real hardware that aren’t in mainline yet but only on Geert’s branch (they might end up in Linux 3.8 though).
Macintosh: no feedback yet.
VME: no feedback yet.
Most outstanding issues are apparently fixed now. We still seem to have invalid locale files leading to lots of segfaults building some d-i package.
rsyslog works now, though you might still want to use sysklogd
Seems to work now, too; apt-get is still better, but pbuilder-satisfydepends-aptitude is usable and does not suffer from #695076 which made building KDE packages impossible.
