Hi
I use gdbserver to debug my program. The problem is gdb can't load
library file correctly.
Belowed is snapshot for my debug process. I think I have set the
right path for loading library file.

I don't know why the path changed to /mnt/cf/shared/lib, this is my target
lib path. Maybe I create the related dir can solve the problem, but I am
glad to know the essential reason and the related solution.
Thx,
Xi
