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:
--command
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) Copyright (C) 2008 Free Software Foundation, Inc. License GPLv3+: GNU GPL version 3 or later This is free software: you are free to change and redistribute it. There is NO WARRANTY, to the extent permitted by law.

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, 设置断点挂起就 可以了;它用于cmds.gdb例如
cmds.gdb
set breakpoint pending on break <source file name>:<line number>
