Run file with gdbserver --multi

Given:

gdbserver --multi :2345

is running on remote machine. I can connect to it with gdb:

(gdb) target remote 192.168.10.248:2345
Remote debugging using 192.168.10.248:2345
The target is not running (try extended-remote?)

(gdb) target extended-remote 192.168.10.248:2345
Remote debugging using 192.168.10.248:2345

What next? How to run some file, say a.out on remote machine and debug it?

Solution

  • What next?

    (gdb) set remote exec-file a.out
(gdb) file a.out
Reading symbols from a.out...
(gdb) b main
Breakpoint 1 at 0x4015ab: file 1.cpp, line 60.
(gdb) r
    • set remote exec-file a.out is used to set the program which you want to debug in the target.
    • file a.out is used to load the debugging symbols from the program in the host.
