In Gdb, how to set a conditional breakpoint on a 3rd line function

Question

How to set a conditional breakpoint on the 3rd line function in GDB?

I know that I can specify the file name + line number, but this does not work for me.
I need to save the gdb commands as a script in order to repeat it later, and I do not want to change the script every time the source file changes.

Answer 1

How to define your own command file for gdb and then just find it during debugging? This would help reduce fair typing. Try the following:

Create a file, name it mydef and here its contents:

define cmd
  b function-where-you-want-to-break
  r
  b +2
  c
end

After loading the executable into gdb, type gdb source mydefat the prompt, and thencmd
