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) . My cmds.gdb looks like this:

set args /home/shlomi/conf/bugs/kde/font-break.txt b IA__FcFontMatch r

However, I’m getting the following:

 shlomi:~/progs/bugs-external/kde/font-breaking$ gdb --command=cmds.gdb... GNU gdb 6.8-2mdv2009.0 (Mandriva Linux release 2009.0) Copyright (C) 2008 Free Software Foundation, Inc.

Type 'show copying' and 'show warranty' for details. This GDB was configured as 'i586-mandriva-linux-gnu'... (no debugging symbols found) Function 'IA__FcFontMatch' not defined. Make breakpoint pending on future shared library load? (y or [n]) [answered N; input not from terminal]

So it doesn’t set the breakpoint after all. How can I make it default to answer ‘y’ to set breakpoints on pending future shared library load?

I recall that I was able to do something, but cannot recall what.

  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 <source file name>:<line number>
