linux x86_64调试linux arm程序

环境：
OS1: ubuntu 20.04 x86_64
OS2: Raspbian GNU/Linux 8.0 (jessie) armv7l

1. raspberry目标机

1.1 linux下编译测试代码

main.c

#include <stdio.h>

int main(void)
{
    printf("hello world\n");
    return 0;
}

编译(也可以在宿主机上交叉编译)

$ cd ~/hello
$ gcc main.c -o hello -g
$ ./hello
hello world

1.2 linux下gdbserver启动调试

$ gdbserver :1234 hello

2. ubuntu目标机

2.1 安装ubuntu下支持linux arm调试的arm-linux-gnueabihf-gdb

安装第三方交叉调试器linaro arm-linux-gnueabihf-gdb

https://releases.linaro.org/components/toolchain/binaries/4.9-2016.02/arm-linux-gnueabihf/gcc-linaro-4.9-2016.02-x86_64_arm-linux-gnueabihf.tar.xz

2.2 同步源码及arm可执行程序

$ tree
hello
├── hello
└── main.c

2.3 使用arm-linux-gnueabihf-gdb调试arm程序

安装第三方交叉调试器linaro arm-linux-gnueabihf-gdb

设置gdb的环境变量

export PATH=~/gcc-linaro-4.9-2016.02-x86_64_arm-linux-gnueabihf/bin:$PATH

调试

$ arm-linux-gnueabihf-gdb hello
(gdb) target remote 192.168.1.101:1234

3. 结果

• ubuntu 20.04宿主机

$ gdb hello
