Subject: Kernel build under meta-toolchain SDK fails
Date: Mon, 22 Nov 2010 20:15:20 -0500 [thread overview]
Message-ID: <87y68kx2l3.fsf@gmail.com> (raw)
Hey all,
Recently I tried updating our openembedded environment for an embedded
application built around the BeagleBoard. Unfortunately, the build
failed while configuring the kernel with an inexplicable bus error. To
trace down the issue I installed the latest meta-toolchain sdk and tried
building a kernel. This resulted in an identical failure,
$ make
HOSTCC scripts/basic/fixdep
In file included from /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/usr/include/stdlib.h:903,
from scripts/basic/fixdep.c:112:

/bin/sh: line 1: 4192 Bus error scripts/basic/fixdep scripts/basic/.fixdep.d scripts/basic/fixdep 'gcc -Wp,-MD,scripts/basic/.fixdep.d -Wall -Wmissing-prototypes -Wstrict-prototypes -O2 -fomit-frame-pointer -o scripts/basic/fixdep scripts/basic/fixdep.c ' > scripts/basic/.fixdep.tmp

make[1]: *** [scripts_basic] Error 2
make: *** No rule to make target `include/config/auto.conf', needed by `include/config/kernel.release'. Stop.
The problem is quite early in the build since even make oldconfig fails
in this way. I tried tracking down the bug on the LKML[1] but after some
discussion it seems very likely the problem is a toolchain issue. At
least part of the problem seems to be in fixdep, which fails very
strangely in fstat[2]. I've done quite a bit of debugging[2], but it
seems to be a bit of a heisenbug.
Interestingly enough, I can reproduce the issue both on my personal
laptop (running Ubuntu 10.10, gcc 4.4.5) and our build server (running
Ubuntu 10.04, gcc 4.4.3). It would be great if someone could try
building a kernel from master using openembedded master. Otherwise, any
ideas would be greatly appreciated.
Cheers,
- Ben
