Hi Daniel,
Yes, the path is incorrect.
Actually the environment (library path) in both my
host computer and my target computer are identical.
Both are of FC1. Do I still need to set up the
solib-absolute-prefix & solib-search-path???
In fact, I have already tried:
1. set solib-absolute-prefix=/dev/null &
solib-search-path=/lib/tls/:/lib,
and
2. leave both empty,
but in both cases, it seems not working : I still
can't see other threads on the host side.
1. I wonder does the version kernel matter on this???
I'm using 2.4.22 (from FC1), do I need to update the
kernel???
2. If I compile my own GDB & GDBserver from 6.3 source
code, do I need to specify any option during
compilation, to order to enable multithread support on
remote debugging????
Thank you for your help.
Regards.
