How to set breakpoints on future shared libraries with a command flag

Question

I\'m trying to automate a gdb session using the --command flag. I\'m trying to set a breakpoint on a function in a shared library (the Unix equivalent of a DLL)

Answer 1

Replying to myself, I'd like to give the answer that someone gave me on IRC:

(gdb) apropos pending
actions -- Specify the actions to be taken at a tracepoint
set breakpoint -- Breakpoint specific settings
set breakpoint pending -- Set debugger's behavior regarding pending breakpoints
show breakpoint -- Breakpoint specific settings
show breakpoint pending -- Show debugger's behavior regarding pending breakpoints

And so set breakpoint pending on does the trick; it is used in cmds.gdb like e.g.

set breakpoint pending on
break :
