Thanks a lot,now I can do gdb command by your advice:
[root at beijing2008 busybox-1.13.4]#export CFLAGS=-g
[root at beijing2008 busybox-1.13.4]#make clean
[root at beijing2008 busybox-1.13.4]#make
[root at beijing2008 busybox-1.13.4]#ls -l busybox_unstripped
[root at beijing2008 busybox-1.13.4]#gdb busybox_unstripped
