linux GDB調試器-02

前文介紹了GDB的編譯。咱們通過編譯以後獲得兩個文件：gdb和gdbserver

下面開始嵌入式中使用gdb進行調試的方法介紹：

1.編譯代碼

arm-linux-gnueabi-gcc test.c -o test -g

必定要加‘-g’參數

2.嵌入式設備端

gdbserver 10.11.2.33:1122 test

gdbserver [IP]:[端口]  測試程序

注：這裏的IP是設備IP，不是主機IP

# ./gdbserver 10.11.22.36:1122 test
Process /mnt/test created; pid = 127
Listening on port 1122
Remote debugging from host 10.11.22.36, port 57984

3.服務器端

target remote 10.11.2.33:1122

進入gdb後，target remote [ip]:[port]

注：這裏的IP是設備IP，不是主機IP
