如何使用命令标志在将来的共享库上设置断点

我正在尝试使用该--command标志自动执行gdb会话。我正在尝试在共享库（相当于DLL的Unix）中的函数上设置断点。我的cmds.gdb看起来像这样：

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

但是，我得到以下信息：

shlomi:~/progs/bugs-external/kde/font-breaking$ gdb --command=cmds.gdb...
GNU gdb 6.8-2mdv2009.0 (Mandriva Linux release 2009.0)

(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]

因此，它毕竟不会设置断点。如何将默认值设置为“ y”，以在未决的将来共享库加载时设置断点？

我记得自己能够做些事情，但无法回忆起什么。

回答：

回覆我自己，我想提供某人在IRC上给我的答案：

(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

因此， 可以了；它用于cmds.gdb例如

set breakpoint pending on
break <source file name>:<line number>
