How is the executable code packaging carried out in the Linux operating system?

In Linux, packaging of executable code usually occurs in the ELF (Executable and Linkable Format). When compiling source code, the compiler and linker create an ELF file that contains several sections: code, data, symbol tables, etc.

The packaging process includes:

• Compiling source files into object files (.o).
• Linking object files and libraries into a single ELF executable.
• Including necessary metadata and tables for the OS loader.

For example, when compiling a Go program, the go build command creates an ELF executable that contains all the necessary code and data for running in Linux.

Thus, packaging is the process of forming an ELF file with code and data, ready for loading and execution in Linux.
