LKBEN11003: Howto show extra information from ELF binaries under linux

Symptom

You need to know specific ELF binary information

Cause

none

Solution

To show extended information about ELF binaries under linux you can use a tool from the binutils called objdump. You cannot only use it on normal binaries but also on libraries.

e.g.

objdump -f getxml

getxml: Dateiformat elf32-i386
Architektur: i386, Flags 0x00000112:
EXEC_P, HAS_SYMS, D_PAGED
Startadresse 0x08049af0

With the option -x you can find out all the header information. (quite a lot)

Option -t shows the symbol tables.
