Hi,

Many thanks for taking the time to reply.

Mmmm.. I'm not sure I understand.
Before the machine got hosed, it was SuSE 9.1, now its Debian testing 
(if that helps any)

Anyhow, I copied the dropbear binary into the toolchain filesystem to 
do an ldd and I got (Debian Host)
ilnacullin:/src# ldd dropbear
ldd: can't open cache '/etc/ld.so.cache'
         libutil.so.0 => /lib/libutil.so.0 (0x40007000)
         libcrypt.so.0 => /lib/libcrypt.so.0 (0x40009000)
         libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x4001d000)
         libc.so.0 => /lib/libc.so.0 (0x40023000)
         ld-uClibc.so.0 => /lib/ld-uClibc.so.0 (0x40000000)

The previous dropbear binary gives the following (SuSE host)
ilnacullin:/src# ldd dropbearold
ldd: can't open cache '/etc/ld.so.cache'
         libutil.so.0 => /lib/libutil.so.0 (0x40007000)
         libcrypt.so.0 => /lib/libcrypt.so.0 (0x40009000)
         libc.so.0 => /lib/libc.so.0 (0x4001d000)
         ld-uClibc.so.0 => /lib/ld-uClibc.so.0 (0x40000000)

Previously I just had copied all the libs from /usr/i386-linux-uclibc/ 
(generated by compiling uClibc itself ) onto my targets filesystem and 
it worked fine, now I've broken it.

The newly compiled dropbear runs fine in the toolchain, so I'm assuming 
that its library structure is correct.  Should I now copy the '/lib' 
directory from the toolchain to my targets filesystem? Could this be 
what I should have been doing all along and I was just lucky 
(blissfully ignorant even)?

Regards
John
