Gdb debugging on Target and Local systems on Linux environment

GDB Debugging

Compile binary with -g option:  gcc file.c -g -o file_out

Development PC works as a client machine:
  $ gdb ./file_out

  (gdb)b main
  (gdb)b filename:10
  (gdb)c //used to run the programe
  (gdb) list
  (gdb) print var

Target GDB Debugging

Target or R&D System :
 $ ifconfig
   11.19.81.198

 $ ./gdbserver.i686 host:2345 ./file_out
   Listening on port 2345
   Remote debugging from host  11.19.89.132


Development PC works as a client machine:
  $ gdb ./file_out

  then connect remote lcoation 
  (gdb) target remote 11.19.81.198:2345
       Reading /lib/ld-linux.so.2 from remote target...
       warning: File transfers from remote targets can be slow. Use "set sysroot" to access files locally instead.

  (gdb) set remote exec-file /bin/true
  (gdb)b main

  (gdb)c //used to run the programe
     Continuing.

Wrappers:

$ gdbserver --wrapper env LD_PRELOAD=libtest.so -- :2222 ./testprog

The --selftest option runs the self tests in gdbserver:

$ gdbserver --selftestmonitor set debug 0

Enable / Disable logs:

(gdb) monitor set debug 1

(gdb) monitor set debug 1
(gdb) monitor set remote-debug 0
(gdb) monitor set remote-debug 1
