A gdb problem.

Source code in on machine A, its binary is on machine B. Binary was complied using -g option.
When I debug it using gdb, it only shows the line number, not the code content at the line. Is there a way for GDB to refer source code at machine B during debug?

Thank you!

I carefully read the webpage, it does not solve my problem:
Suppose code on A machine is at 129.1.1.1:/home/test/code/

I am debugging on B machine.
I launched gdb example_test
(gdb) set substitute-path /home/test/code/ 129.1.1.1:/home/test/code/

No symbol "substitute" in current context.

It seems "dir" or "set substitute-path" is just referring code on the same machine, but not between 2 machines?

Unless you can use NFS to mount a directory on machine A onto machine B, you have to copy the source from one to the other. It can be a real pain to do that, but it's unfortunately not possible to solve in any other way. [At least, I can't think of any other way].

Thank you!
One more question: why "set substitute-path" doesn't work in my gdb?

(gdb) set substitute-path
No symbol "substitute" in current context.
