 Posted: Wed Jul 02, 2008 4:42 pm Post subject: [ARM] error: C compiler cannot create executables |
 |
|
Hi,
I just updated to uclibc-0.9.29 from uclibc-0.9.28-r4 and now whenever I try to emerge anything I get...
| Code: |
error: C compiler cannot create executables
|
I've done nothing to touch the /etc/make.profile or /etc/make.conf settings, it seems to be that uclibc is screwed.
Is there anyway of recovering my system without doing a fresh install (I don't currently have a cross-compiler environment set up).
There is a thread in the mailing list (here) but it looks like that was resolved due to strange CFLAGS, none of which I have set (see below).

This is a Gentoo system on an NSLU2 (or Slug) installed on an external HD.
Thanks in advance,

This also seems to have destroyed ssh access to the machine 
Fortunately I have an open connection so I can still do stuff, but I'm loathe to disconnect in case it screws everything
Theres ann FAQ on this here and it points to a long thread on this here that I'm working my way through, but most of it seems to be to do with x86 archs and the general problem is one of CFLAGS not being read correctly.
Unfortunately since I'm at work I can't try anything suggested, but will do upon returning home this evening.
Any hints or tips on appropriate CFLAGS or why they're not being read properly would be appreciated in the meantime.

Okay, had to reset the NSLU2 due to a power cut.
Seems to reboots fine and boot from Gentoo, network filesystems are exported and can be mounted by my desktop, unfortunately I can no longer ssh into the NSLU2 when its booted from the Gentoo system.
Hmm, what to do?
I booted from the OpenSlug OS I installed from flash without the USB HD attached and then chroot'd into the environment.
It appears that sshd now segfaults on execution hence why I couldn't ssh into the system when booting from the external gentoo HD.
I can't re-emerge things either as I'm still getting the "C compiler cannot create executables"
I'm loathe to re-install as it took quite a while to suss everything out.
Thoughts on a postcard to this address please.
Cheers

okay, I think I've sussed the cause of this.
I tried bumping uclibc to 0.9.29 by copying the last ebuild uclibc-0.9.28-r7 to a local overlay. Now under eix I have two slots, but the bumped 0.9.29 is in a different slot to the others...
| Code: |
# eix -e sys-libs/uclibc
[I] sys-libs/uclibc
Available versions:
(i686-pc-linux-uclibc) 0.9.27-r1 0.9.28.3 0.9.28.3-r3 (~)0.9.28.3-r6 (~)0.9.28.3-r7
(arm-pc-linux-uclibc) (~)0.9.29[1]
{build debug hardened iconv ipv6 minimal nls pregen savedconfig uclibc-compat userlocales wordexp}
Installed versions: 0.9.29(arm-pc-linux-uclibc)[1](15:18:36 07/02/08)(uclibc-compat -build -debug -hardened -iconv -ipv6 -minimal -nls -pregen -savedconfig -userlocales -wordexp)
Homepage: http://www.uclibc.org/
Description: C library for developing embedded Linux systems

The question is, how do I get back to a working system?
If I were to grab a stage3 tarball which files and libraries would I need to extract and copy over?
