如何使用命令標誌在將來的共享庫上設置斷點

我試圖使用--command標誌自動化gdb會話。我試圖在一個共享庫的函數中設置一個斷點（一個DLL的Unix等價物）。我cmds.gdb看起來是這樣的：如何使用命令標誌在將來的共享庫上設置斷點

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

不過，我得到以下幾點：

 
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]

所以它不設置斷點畢竟。我怎樣才能讓它默認回答「y」來設置將來未來共享庫加載的斷點？

我記得我能夠做些事情，但不記得是什麼。

在回答自己解釋說，我想給的答案，有人給了我在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

所以設置斷點上未決的伎倆;它被用於cmds.gdb，例如，

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

耶！今天我學到了一些關於GDB的新東西=） – Branan 2008-09-19 15:46:59

已經保存了我的培根，嘗試在Windows 7下使用MinGW進行調試，默認設置與Linux不同 - 很多謝謝 – bph 2012-05-16 09:22:20

例如，您需要在main中斷，然後運行到該中斷。所以共享庫將被加載。

沒有符號。

objdump -t /lib/libacl.so 
SYMBOL TABLE: 
no symbols 
objdump -T /lib/libacl.so 
... 
00002bd0 g DF .text 000000d0 ACL_1.0  acl_delete_entry 
... 


(gdb) break 0x0002bd0 

(gdb) x/20i acl_delete_entry 
0x2bd0 <acl_delete_entry>:  stwu r1,-32(r1) 
0x2bd4 <acl_delete_entry+4>: mflr r0

OT：在終端它看起來像這樣調試卡哈在一條線：

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