[linux-sh:03398] Re: sh3 problems with shared libraries

A small updated:

I've downloaded all srpms from the www.sh-linux.org website. Then i've 
unpacked them using rpm2targz. Everything is availabel at 
www.jlime.com/downloads/Various/patches  . One or more of these patches 
should fix the problem seeing as how the www.sh-llinux.org binaries work 
well.
As you all realize is this a big handicap for the linux-sh3 community.


So far i've implemented one binutils patch and one gcc but no cigar yet.

Any futher assistance would be greatly appreciated.

Best wishes
Kristoffer
