gdbserver couldn't find thread library

gdbserver couldn't find thread library

[Frank Chen]

I am debugging a multi-threaded program using
gdbserver. The function call to td_ta_new in
thread_db_init() (in thread_db.c) returns
TD_NOLIBTHREAD. And the program does not run properly
afterwards.

However, when I debug the same program locally using
gdb, it works fine. The gdb displays the following
message during start up.

Using host libthread_db library
"/lib/tls/libthread_db.so.1"

Since this is a UI program, running gdb locally
doesn't work. I would like to use the gdbserver. It
seems that I need to point gdbserver to the above
location for the thread library. Could someone tell me
how to do that?

Thanks,

Frank

You need to point GDB at the exact same versions of libraries that you
are using on the machine running gdbserver.  I recommend using
"set solib-absolute-prefix".  If you're still having trouble, and you
can't find an answer in the list archives, please show us exactly what
commands you are using.
