gdb加了-g仍然(no debugging symbols found)

想用 gdb 对程序进行调试,之前的时候就想用 gdb 的,结果发现加了 -g 也还是不行,显示如下:

因为当时时间紧迫,就没来得及去找原因,今天找了下原因
一般来说,如果加了
-g 仍然找不到符号,要么是只是在 .o文件生成可执行文件的时候加的-g,而在.c生成.o 文件时忘记加了,要么是把可执行文件 strip 了,可是我查找我的 Makefile ,这两种可能都不是。写了小的测试程序,发现是可以 gdb 的,怀疑还是我 Makefile flag 写的不对,查找,发现有个 -s 的选项,查资料发现,原来是它把我的符号给去掉了,去掉 -s ok,done
执行调试命令以后出现下面输出,无法继续调试 ~ # id uid=0(root) gid=0(root) groups=0(root) ~ # gdb -p 567 GNU gdb (Debian 7.7.1+dfsg-5) 7.7.1 Copyright (C) 2014 Free Software Foundation, Inc.
