Keith, What ppc target are you using? The docs you referenced may work for ppc with hardware floating point but definitely not for those without...like mpc860.
I have finally got the cross environment built and working for 860...in fact I had just got my target booted and running sash when your post came in. :) I used the penguinppc docs and Wolfgang Denks CDK ( ftp://ftp.denx.de/pub/LinuxPPC/usr/src/CDK.tar.gz ) for reference. Mostly just adapting the denx stuff to the package versions I was using. I used the following packages: binutils-2.12.90.0.1 gcc-core-2.95.3 gcc-2.95.3 glibc-2.2.5 linux-2.4.4-2001-07-23 ( from ftp://ftp.denx.de ) The denx CDK makefiles and patches require a little modification to work with these packages. Specifically, the gcc specs patch, and the floating point mods in 'Makefile.glibc'. The specs patch needed a little tweak due to minor changes in the second hunk, while most of the floating point mods were already in the glibc-2.2.5 package...I just removed what was already incorporated. The only thing I'm not satisfied with at this point is I still need to make a link on my target file system with the full path to the CDK lib directory as on my host... from target filesystem root: mkdir -p /home/paulr/linuxppc/CDK cd /home/paulr/linuxppc/CDK ln -s /lib The path is hardcoded into 'ld-2.2.5.so'. This was a 'feature' of HHL 1.2 but fixed in HHL 2.0 ( which is no longer available from their website ). I have the 2.0 source disk somewhere and the required patch to glibc may be in there...or someone who knows what the fix is may chime in here :) If you still need help I would be happy to send you my scripts ( yes, I did the whole thing in bash scripts...as a exercise mostly...would be just as easy/easier to modify the denx makefiles. -- Paul Ruhland On Monday 25 March 2002 02:34 pm, Keith Outwater wrote: > Greetings all - > I built the powerpc-linux cross toolset from source using the > cross-compiling mini-howto on www.penguinppc.org.
