How to set breakpoints on future shared libraries with a command flag
Replying to myself, I'd like to give the answer that someone gave me on IRC:
(gdb) apropos pendingactions -- Specify the actions to be taken at a tracepointset breakpoint -- Breakpoint specific settingsset breakpoint pending -- Set debugger's behavior regarding pending breakpointsshow breakpoint -- Breakpoint specific settingsshow 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 onbreak <source file name>:<line number>
With no symbols.
