我正在尝试使用–command标志自动化gdb会话.我正在尝试在共享库(Unix的等价物DLL)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.txtb IA__FcFontMatchr 但是
set args /home/shlomi/conf/bugs/kde/font-break.txt b IA__FcFontMatch r
但是,我得到以下内容：
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.

Make breakpoint pending on future shared library load? (y or [n]) [answered N; input not from terminal]
所以它毕竟不设置断点.如何使其默认回答“y”以在挂起的未来共享库加载时设置断点？
我记得我能够做点什么,但不记得是什么.
回答我自己,我想给出一个人在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
所以设置断点等待诀窍;它在cmds.gdb中使用,例如
set breakpoint pending on break <source file name>:<line number>
