elf - readelf error: not an elf file, wrong magic bytes at the start

Question

I am trying to learn and use Elfreader by compiling a simple hello world program to a elf file as-

gcc -o test test.c

The file compiles correctly and runs perfect. But when I try to run ReadElf on it by

readelf -h test

it returns

readelf: Error: Not and ELF file - it has the wrong magic bytes at the start

What do you think I am doing wrong, or is there a problem with my linker script? Let me know if you need any additional info from me.

Answer 1

您可以检查文件格式类型如下：

$ objdump -t hello.exe

hello.exe：文件格式pei-i386

也许我猜你的文件不是精灵格式。
