Re: Linksys NSLU2 (evbarm, armeb) userspace regression origin found
Hi again,
I have created the attached patch to fix the user space issue
introduced by the commit quoted in the mail below (basically adding
also ' TARGET_ENDIAN_DEFAULT=MASK_BIG_END' to tm_defines).
Using NetBSD 6.1.5 kernel and some more recent user spaces generated
from trunk (for instance, 'build', 'distribution', sets' obtained from
trunk code dated 2013-09-14), I get a lot of messages
'/etc/ld.so.conf: invalid/unknown sysctl for libc.so.12 (22)' after
starting init.
Any idea what this is? Is it due to the fact I am using NetBSD
6.1.5_PATCH kernel with newer userspace (etc/obj/etc-release says
'NetBSD 6.99.23/evbarm')?
