Whenever we compile any code, the output that we get is an executable file, which we generally don’t bother about. We execute it on our desired target. If it is an embedded system, we flash it to the target device and run it. Usually, this executable file is the ELF (Executable and Linkable Format) file. In this article we will analyse the compilation process as well as ELF. To begin with, there are many compilation stages so let us look at them more closely.
