查查看你的 Makefile, 看看 gcc 在 compile 的時候 有沒有用到 -s 這個 option 或者是有用了 strip 這支程式, 這樣會拿掉執行檔裡面的符號表, 如此可減少執行檔的大小, 不過在用 gdb debug 的時候得要記得把 strip 拿掉才行 :) ※ 引述《[email protected] (kmsh.twbbs.org)》之銘言： : 我在Makefile的 CFLAGS 裡有加上 -ggdb : 然後再去trace core dump時 : 如下 : > gdb checkdir checkdir.core : GNU gdb 4.18 : Copyright 1998 Free Software Foundation, Inc. : GDB is free software, covered by the GNU General Public License, and you are : welcome to change it and/or distribute copies of it under certain conditions. : Type "show copying" to see the conditions. : There is absolutely no warranty for GDB.
