[Buildroot] ARM EABI toolchain - anyone build it successfully?

[Tomasz Chmielewski]

I'm trying to make ARM EABI toolchain using the latest snapshot of 
Buildroot.
However, no matter which options I use (thread library implementation, 
uClibc version etc.) I'm only able to build GCC (4.3.1).

Then, it breaks later on on building uClibc.

I also tried building uClibc from nptl branch, but it also failed.

As different thread library implementations and uClibc versions give 
different errors, I won't paste it here, unless requested.

So my question - did anyone manage to build ARM EABI toolchain with 
buildroot (GCC 4.3.1 + uClibc; I also need busybox)?

Do you still have it anywhere?

If yes, could you paste your .config for Buildroot?

If possible, also .config for uClibc?

Unfortunately i've lost the disk that contained the configs, but going
off a minimal config should work fine.

OK, it builds (I had a custom uClibc config, which perhaps made some 
problems), but even then, lots of Busybox things don't work.

I.e.:

# ./busybox
(...)
Currently defined functions:
         ash, cat, mount, sh, sleep, switch_root, umount, whoami

# ./busybox ash
Illegal instruction


Similar to: http://bugs.busybox.net/view.php?id=3364 which maybe points 
to http://bugs.busybox.net/view.php?id=0003804 (some things are build as 
EABI, and some things are build as OABI, although EABI is chosen).

what CPU did you select? ISTR that i have fixed this for iWMMXT && EABI

BTW, I know why it initially failed for me - I removed networking support in uClibc configuration, which resulted in:

BTW, could you point which changes you did to fix this issue for iWMMXT 
&& EABI?

and

xscale is supposed to work just fine here.

well yes, that's somewhat expected :) I usually do not do threads. If
you need threads, you should at least turn on socket support for obvious
reasons.

I'm not very familiar with buildroot's versioning - how can I find those 
changes?

Well, it doesn't :(

Out of all shels, only hush and lush work:

# ./busybox
(...)
Currently defined functions:
         ash, cat, hush, lash, mount, msh, sh, sleep, switch_root, 
umount, whoami


# ./busybox ash
Illegal instruction
# ./busybox hush
/tmp # exit
# ./busybox lash
/tmp # exit
# ./busybox msh
# Illegal instruction
# ./busybox sh
Illegal instruction


Hopefully hush is enough ;)

Unfortunately, it breaks, too:

# ./busybox hush
/tmp # BLAH=1
/tmp # if [ $BLAH == 1 ] ; then
 > ./busybox whoami
 > fi
Illegal instruction
