c++ - command. "file" the use loaded. is table symbol no How to set breakpoints on future shared libraries with a command flag

1 Answers

OT: In terminal it would look like this to debug Caja in one line:

gdb -ex "set breakpoint pending on" -ex "break gdk_x_error" -ex run --args caja --sync
gdb set breakpoint

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

However, I'm getting the following:

shlomi:~/progs/bugs-external/kde/font-breaking$ gdb --command=cmds.gdb...

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.
