RE: Fwd: Sparc Arch status

Jack Morgan,

Thanks for offering your plan for gentoo-sparc. I'm interested in
gentoo-sparc as well and I'd like to help if I could. Regarding the
points you brought up, here are my thoughts.

(1) Bugzilla

In Feb. 2015 I was looking for sparc related issues to resolve and I
found bug #532088, a SIGBUS crash in openvpn caused by an LZO bug. I
worked with the LZO author to fix the problem and the fix is included in
lzo version 2.09. I created a gentoo bug to describe the issue and the
fix (upgrade to 2.09), #539760. It would be great to get LZO upgraded to
2.09 because LZO is currently completely broken on sparc.

(2) Installation

The documentation seems to be in good shape, except for a couple issues
I identified:

a) The only filesystem tools that seem to be included on the live cd are
e2fsprogs. This isn't really a problem except that the handbook
describes the other filesystems such as xfs, js, etc. Is there a reason
the other tools are omitted? If so, we should probably not present them
as options in the handbook.

b) The other issue I saw was that the handbook recommends -march=native
when gcc doesn't even seem to support any "-march" flags on
sparc, instead using "-mcpu" or "-mtune". I believe "-mcpu=native"
should work similarly.

As for the live cd itself I was unable to create a working system from
the current image. As soon as I upgrade glibc from what's in the current
stage3 tarball to the latest stable I get lots of "wait_for: No record
of process 0" errors when running programs, particularly portage. This
was the case compiling glibc with the gcc 4.7.x included in the
current stage3 and with the latest stable 4.8.4.

I'm not sure what the exact problem is. It may be related to the age of
the stage3, currently from 2014-12-01. I was wondering if you had any
ideas of what could be causing this before I try again.

4) Once I get a working system I'm interested in getting systemd
working.

I'm also very interested in getting java working. There recently has
been some work upstream in openjdk fixing linux/sparc support and as
a result IcedTea 2.5.5 compiles and runs for me on debian/sparc. Because
of this I'm certain we could put together a working ebuild for gentoo.

Thanks,
David Mattli

It looks like I was being affected by bug #550836. Heh that's some bad
timing. Now that it's masked I'll try to install again when I get the
chance.
