While I started a clean install w/ ext toolchain (crosstool-ng -1.6.1),
I noticed that menuconfig still has a snag in it when starting from
scratch with config :

When HAL is not used and ext toolchain selected, udev & hotplug are
*not* displayed nor selected. 
busybox-show-others has to be enabled and they both have to be
explicitly enabled from there.
BR versions < 2009.11 turned 'em on when mdev was selected.

Perhaps it's deemed that HAL should be selected, dunno.

In any case, hotplug & udev should not be suppressed by SHOW_OTHERS,
since even busybox-1.16.1 does NOT offer them...

More feedback when I completely rebuild.

PS : ct-ng only offers "linuxthreads". So are we supposed to use
"stable/old" in BR or "new" (latter, I guess) ????
I seem to have had problems with that - invoking gdbserver prompts :
"can't load libthread_db.so.1".
This worked fine with internal toolchain... Anyone ?

HTH

I don;t know if I'm off base here, but I notice that rc3 does not have
the patches for uClibc 0.9.30.1 at toolchain/uClibc folder in the
tarball ?????

That's only true if you build a uClibc-based toolchain. If you build a
glibc- or a eglibc-based toolchain, then crosstool-NG allows you to
use NPTL.

So I'll take that you build a uClibc-based toolchain...

That has to match the way you configured uClibc in your toolchain.
Check the uClibc .config file for that.

libthread_db.so.1 is dlopen(3)ed by gdbserver, so you have to get it on
your target, in the standard libraries search path.

Also, there is a known dangling issue wrt cross-gdb + gdbserver.
See this thread:
  http://lists.busybox.net/pipermail/buildroot/2010-May/034435.html

In short, you have to get the cross-gdb *and* the gdbserver from the
same version of gdb, to be sure they know how to speak to each other.
So: either get both from crosstool-NG, or get both from buildroot.

Yann E. MORIN.

Indeed, that because the 0.9.30.x that is used is .3, and .1 is not present
in the version choice, in the menuconfig. See:
  toolchain/uClibc/Config.in at 40

Thanks for reviewing.
This might have sounded like a dumb question - as of course uClibc was
compiled by ct-ng...
I haven't yet compiled BR, am about to though. I saw uClibc 0.1.29
patches, so I thought "where's 0.9.30.1 ??".

I mean, if 0.9.30.3 is used, why bother with 0.9.29 patches ???
Oh well, false alarm in any case !!

The *biggest* problem so far I had was the fact that ct-ng-1.6.1 patches
uClibc 0.9.30.1 BUT does NOT apply the ARM sysdep patch.
I kept getting "invalid module format" on my target. A rebuild with
(indeed) "new" linuxthreads enabled in uClibc of the x-tools toolchain
fixed it after manually applying the sysdeps patch !!

I'll still reply to your other post as well.

Au revoir,
Kris

I've been compiling with both from buildroot at all times, so that
should be OK.
While I was doing a sanity check vis-a-vis (sorry for the missing accent
grave) module inserting (solved), I used an older kernel uImage
(generated when I still used internal BR toolchain).

gdbserver of course is still happy there, but I can't find a trace of
libthread_db.so.1 on my rootfs target. (looked in /lib and /usr/lib).
I do have libpthread.so.0 etc.
I tried with an ltrace but that's not helping much.. (only see
__uClib_main)

I'll compile shortly and keep you posted.

Thanks for the help Yann, it's greatly appreciated !

When gdbserver was bleating about libthread_db.so.1, it was in the staging directory,
but it wasn't placed on the target rootfs.
When I manually added it on the target (libthread_db.so.1 I mean), gdbserver worked good as gold then...

I still come across 2 build errors with rc3 :

1. lockfile-progs-0.1.11
========================
The generated Makefile causes a build error in :
CFLAGS    := -g -Wall -Werror -O2
I still need to remove the -Werror to resume the build ??

2. gdb symlink
==============
ct-ng generates arm-unknown-linux-uclibcgnueabi where I have
arm-elf-xxx as an alias.
The build stops when the symlink for gdb fails. I need to manually
insert a folder 'arm-unknown-linux-uclibcgnueabi' with 'bin' as a
subfolder under ../output/staging/usr

The error is some such :

install
-c /home/kris/buildroot-2010.05-rc3/output/toolchain/gdbhost-6.8/gdb/gdb /home/kris/x-tools/arm-unknown-linux-uclibcgnueabi/bin/arm-elf-gdb
ln -snf ../../bin/arm-unknown-linux-uclibcgnueabi-gdb \
		/home/kris/buildroot-2010.05-rc3/output/staging/usr/arm-unknown-linux-uclibcgnueabi/bin/gdb
ln: creating symbolic link

make: ***
[/home/kris/x-tools/arm-unknown-linux-uclibcgnueabi/bin/arm-elf-gdb]
Error 1


AFAIK I'm using the tool turnkey manner.
Can you advise ?

I hope the list will forgive me sending to you & list.
Your posts have not reached me at all yet through busybox.net :-(

A follow-up as promised.
I'm rather surprised that the new build still bleats about 'can't load
libthread_db.so.1' when starting gdbserver...
That lib is in ../staging/lib as a symlink to libthread_db-0.9.30.1.so.
There's also a symlink in /staging/usr/lib called libthread_db.so which
points to libthread_db.so.1 - hmm.

As mentioned, the previous rootfs runs fine, however there is no trace
of this lib on the target.

I'm a bit stumped on this one.
I've used linuxthreads (new) in uclibc 0.9.30.1 config.

TIA
Ici avec beaucoup de soucis !!!

Sorry for brief delay.
Have my feet back under desk now. Need to do some fiddling on XP first,
but then back to Linux.
I noticed that 2010.05 is fully released now, so I'll start from there.
I'm not sure if your fix is in 2010.05 final or not, but I guess we'll
see shortly.
I will delete 2010.05-rc3 folder and rebuild with 2010.05 final and go
from there. Will keep you posted.

Thanks for reviewing !

Thanks for reviewing. 
Does this mean the fix is also in final 2010.05 tarball ?
(I'm not used to git, I probably should learn, have been thinking about
using it for my CVS)

I must have given away somewhere, I guess, that I'm originally Belgian ?
I live in Australia since 1989, but lived 25 years in Belgium. I mean, I
could have been Dutch ? :-)

Tusend Tak ! :-) (I think this is acceptable Danish ?)

2010.05 builds 100% fine now, except for the little snag with the gdb
symlink. I'll see if I can figure out what the common denominator is,
but I'm a bit stumped.

I find I still have to manually insert the folder
'arm-unknown-linux-uclibcgnueabi' with 'bin' as a subfolder under
buildroot-2010.05/output/staging/usr

(ext toolchain built with CT-NG 1.6.1, alias used is 'arm-elf-xxx'

Can you advise ?

All the best
Kris

FYI, strace now does show the proper lib call (naturally :-) :

# strace gdbserver
execve("/usr/bin/gdbserver", ["gdbserver"], [/* 16 vars */]) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0x40005000
open("/lib/libthread_db.so.1", O_RDONLY) = 3
fstat(3, {st_mode=S_IFREG|0755, [SNIP].... etc....

Can you give a .config or reproduction steps for this ?

FWIW, arm-elf is a prefix typically used for bare-metal toolchains, but
here you're doing an uClibc/Linux toolchain, which is fairly different.
It probably doesn't cause particular problems but might be confusing.

Thomas
