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 !!!
