I downloaded the latest GDB code "gdb+dejagnu-weekly-20021001.tar.bz2" from
sources.rehat.com, and rebuild the gdbserver and gdb for powerpc target,
then I used the gdbserver to debug a multi-threads programme in target, if
the breakpoint was set in main routine, it's OK, but if the break point was
set within any other child thread, the break point can be hit, however, the
debug cusor is not shown and the gdb say it is going to libc.so, if I say n,
the target programme will crash.

I try to set "solib-search-path" to the target share lib path, the problem
remains same.

I used nfs to map the root file system to target.

Any thought? Any suggestion?

Thanks

here is the display of the gdb
