I've emerged sparc sources with:
USE=ultra1 emerge sparc-sources-2.4.25.ebuild
I use the same .config as before with .23, with just some changes to ncpfs
support. I think I also added an option to catch kernel buffer overflow
(maybe that is where this is coming from).
When doing make vmlinux I get this error:
| Code: | ld -m elf64_sparc -T arch/sparc64/vmlinux.lds arch/sparc64/kernel/head.o arch/sparc64/k ernel/init_task.o init/main.o init/version.o init/do_mounts.o \

Anyone have an idea what is wrong? |

I figured it out on my own. It was a kernel debug option for catching buffer overflow. I guess it doesn't work all by it's lonesome, so I just disabled that option and then the kernel compiled fine.
# MCONFIG=not set
is the way to go... |
