ELF Object File Format Specification

This technical documentation outlines the ELF (Executable and Linkable Format), a standardized structure for binary files used in program linking and execution. It defines three primary file types—relocatable, executable, and shared objects—and details the ELF header which acts as a roadmap for the file's contents. The text explains how sections manage data for linking, while segments and program headers guide the system during process image creation. Key mechanisms described include symbol tables for resolving references, relocation for adjusting memory addresses, and dynamic linking for attaching shared libraries at runtime. By providing machine-independent data representations for both 32-bit and 64-bit architectures, the format ensures extensibility and portability across various operating systems and processors. This specification serves as a foundational guide for developers and system architects working with binary interfaces and software installation.
