Could you try with a more recent Buildroot version, say 2009.11 ? If it
still fails, please send your .config.

Did you really recompile *all* your applications with the toolchain
generated by Buildroot ? Remember that uClibc doesn't provide any kind
of ABI backward compatibility, so you have to recompile your
applications with exactly the toolchain that uses the C library that is
on the target.

Did you use the default uClibc configuration file, or did you customize
it somehow ?

Cheers,

Thomas
