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.
