"Undefined symbols"

[Nick Clifton]

Hi Dr Xinan,

>     I am using GNU ld version 2.10 (with BF 2.10) and I found out 

2.10 is an old version of GNU ld.  I would first recommend upgrading
to the latest released version (2.11.1) or the latest CVS sources.

L31 is a local label, which may be why it is being ignored by the
linker.

You could try adding "--trace-symbol L31" to your linker command line
to see if this helps.

If you can provide a small test case and also tell us which target
configuration you are using then we may be able to reproduce the
problem and offer further insights.
