[oe-users] PowerPC build failing in glibc-intermediate

[Benjamin Heyne]

Hi all,
I am new to OpenEmbedded, and just trying to build the first system with it - I have used buildroot previously.

I need to build a PowerPC 405 RFS, so I have used dht-walnut as machine and oplinux as distro without any changes.
Unfortunately the build of "bootstrap-image" always fails at glibc-intermediate (I have tried several versions after first
failure - always the same result, also tried angstrom-2007.1 distro without success...):

In the archives I've seen that someone else had the same problem (Thread "State of PowerPC" in September) - But there was no solution given.
I also couldn't find this bug in Bugzilla. As I am just starting with OpenEmbedded, I probably don't know
enought of the internals of it to find the problem myself in reasonable time - So any hint would be appreciated...Is it a bug of OE or of the user? ;-)
Is there any option I could change to make it work?

Best regards
