nobody yet? Well, I've been trying several combinations of the programs,
and they still all fail. I've had success with binutils-2.17, with gcc
3.4.1-r3, 3.4.4-r1 and 4.1.1-r3, but no luck with uclibc.
I've tried uclibc 0.9.28-r2, 0.9.28-r1 and 0.9.28 (as well as 0.9.27
that apparently does not support sparc?), and every time they fail on
the same problem, complaining about duplicate "_start" symbol in ldso.c.
I've attached my uclibc emerge log, hopefully someone can propose
something?
thank you,
Dimitris

you may try to use uclibc-svn (no ebuild for it), some sparc support was
added.

Hmmm, uclibc from SVN does the trick. I also tried buildroot and I was
able to produce a working toolchain for softfloat SPARC, out of:
binutils-2.6.91.0.7
linux-kernel-2.6.11
gcc-3.4.2
latest snapshot of uclibc
Thank you Peter for your time,
Dimitris

don't rely though on the svn version for production, the locking is housed
(many other bugs that I won't even try listing them).
