Re: [NEED HELP] Problem to multithread remote debugging with GDBserver

[Peter Choi <peter_tkchoi@yahoo.com>]

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.
Peter Choi
