Below are the stages that happen in order regardless of the operating system/compiler and graphically illustrated in Figure w.1. Normally the C’s program building process involves four stages and utilizes different ‘tools’ such as a preprocessor, compiler, assembler, and linker.Īt the end there should be a single executable file. Have a nice day!Īble to understand and appreciate the processes involved in preprocessing, compiling, linking, loading and running C/C++ programs. The commands and examples of the gcc, gdb, g++, gas and friends are discussed in Linux gnu gcc, g++, gdb and gas 1 and Linux gnu gcc, g++, gdb and gas 2. the processes discussed here quite transparent. When you use the IDE (Integrated Development Environment) compilers such as Microsoft Visual C++, Borland C++ Builder etc. It is based on the GCC (GNU Compiler Collection). It tries to investigate how the C/C++ source codes preprocessed, compiled, linked and loaded as a running program. However, it is an excerpt from more complete, Tenouk's buffer overflow Tutorial. This Module presents quite a detail story of a process (running program). COMPILER, ASSEMBLER, LINKER AND LOADER: A BRIEF STORY
