What is a relocatable ELF file?

This chapter describes the object file format, called ELF (Executable and Linking Format). There are three main types of object files. A relocatable file holds code and data suitable for linking with other object files to create an executable or a shared object file.

How ELF file is executed?

An ELF file consists of zero or more segments, and describe how to create a process/memory image for runtime execution. When the kernel sees these segments, it uses them to map them into virtual address space, using the mmap(2) system call. In other words, it converts predefined instructions into a memory image.

What is ELF file describe the format?

In computing, the Executable and Linkable Format (ELF, formerly named Extensible Linking Format), is a common standard file format for executable files, object code, shared libraries, and core dumps.

What is the difference between object file and executable?

The main difference between object file and executable file is that an object file is a file generated after compiling the source code while an executable file is a file generated after linking a set of object files together using a linker. C is a general-purpose, high-level programming language.

What is linker file?

In computing, a linker or link editor is a computer system program that takes one or more object files (generated by a compiler or an assembler) and combines them into a single executable file, library file, or another “object” file.

How do I load an elf file?

Loading ELF file

1. Read the ELF header and do some basic verification.
2. Calculate how much memory we need for the program and allocate it.
3. Copy data from the ELF file in memory.
4. Call the entry point of the program.

How is elf file created?

The ELF file is built for an x86-64 bit machine. There are two important pieces of information present in the ELF header. One is the ELF program header part and the other is the ELF section header part. When a program is compiled, different things are generated after compilation.

How do I read ELF files?

you can use readelf and objdump to read parts of an elf file. You can also use ‘hexdump filename’ to get a hexdump of the contents of a binary file (this is likely only useful if you like reading machine code or you are writing an assembler).
