Today I will be talking about ELF, a format used well used nowadays on micro technology although on open systems already in use on the market.
gcc -o main.c a.out
This is our example to use and verify ELF format. It’s a format used since 1999, as a standard. It can be called a standardisation.
With ELF we can, debug, study how the behaviour of the system have under the CPU and the format CPU smp. It can run on 32 bit and 64 bit cpu.
In Linux if you want to have a describe style for the format, you can run this command on the terminal or in MacOS (Terminal or iTerm2)
file a.out or the name you gave file main.out
To make use of debugging under ELF format is useful to study how the Operating System behaves. Perhaps the libraries are built or their behave too.
