Ubuntu20.04手动安装binutils objdump、arm-linux-objdump: command not found、bash: hello.s: Permission denie

objdump: command not found

解决：下载binutils仍然无法使用objdump

操作背景：

使用的是Ubuntu 20.04的WSL

安装好了ARM32的交叉编译工具：sudo apt install gcc-arm-linux-gnueabi

通过C语言的.c 文件编译出可执行文件


arm-linux-gnueabi-gcc -E hello.c -o hello.i
arm-linux-gnueabi-gcc -S hello.i -o hello.s
arm-linux-gnueabi-gcc -c hello.s -o hello.o
arm-linux-gnueabi-gcc  hello.o -o hello

其中编译出的.s 汇编文件不够精简，包含很多C语言到汇编语言实现的说明

然后想通过把可执行文件的反汇编，来得到纯粹的.s 汇编文件，来直观的学习汇编语言的语法和格式

操作过程

1.执行反汇编语句：

arm-linux-objdump -d hello > arm_hello.s

然后系统提示我：arm-linux-objdump: command not found

或有时提示我：bash: hello.s: Permission denied

2.然后我查到说objdump是binutils下的工具

所以我从http://ftp.gnu.org/gnu/binutils/下载了binutils-2.37.tar.gz这个包，导入了到Linux系统中，并且解压
然后在解压的目录内执行了
./configure
make
sudo make install
然后我执行这个命令：arm-linux-gnueabi-objdump -d hello > arm_hello.s

成功！

一定要在要在解压的目录内执行第二步语句，如果还是解决不了，可以再在目录下试一下下面的命令

export CC=afl-gcc； export CXX=afl-g++；

sudo bash -c 'echo core >/proc/sys/kernel/core_pattern'

sudo apt-get install texinfo

一定要在objdump前面加上gnueabi

arm-linux-gnueabi-objdump -d hello > arm_hello.s

祝你好运如果还解决不了，可以评论区留言
