gdb + nasm调试信息未被创建 [英] gdb + nasm debug info not being created

问题描述

我比较新的汇编语言编程，我试图调试我在Ubuntu中编写的一个小的.asm文件。我遇到一个问题，我的符号表没有加载，并且正在寻找一些帮助。

我正在编译我的程序如下。

  nasm -f elf -g -F dwarf bs.asm 
 gcc -m32 -g bs.o -o bs 
  

当我运行

  gdb bs 
  

我收到一条消息，表示没有调试符号，当我尝试通过

设置断点

  b main 
  

它表示功能没有定义，即使它在文件中，我可以使用./bs

几个帖子，建议在组装时添加-F矮人，但是如果有任何人有任何见解，则不会有任何帮助。我将非常感谢您的输入。

解决方案

使用以下命令组合文件： -

nasm -f elf -F dwarf -g file.asm

ld -m elf_i386 -o file file.o

然后使用gdb，

I am relatively new to assembly language programming and am trying to debug a small .asm file that I wrote in Ubuntu. I am however running into an issue where my symbol table is not being loaded and was looking for some help.

I am compiling my program as follows.

nasm -f elf -g -F dwarf bs.asm
gcc -m32 -g bs.o -o bs

which produces the executable bs when I run

gdb bs 

I get a message that says no debugging symbols and when I try to set a break point by

b main 

it says function not defined even though its in the file and I can run it using ./bs

I read a couple posts that suggested adding the -F dwarf when assembling but that didn't help if anyone has any insight I would greatly appreciated your input.

解决方案

Assemble your file with the following commands :-

nasm -f elf -F dwarf -g file.asm
ld -m elf_i386 -o file file.o

and then use gdb,
