Therefore, it can be compiled without problems: $ g++ -o guarded main-guarded.cppīut the main-unguarded.cpp file includes unguarded.hpp twice: #include "unguarded.hpp"Īnd the preprocessed output shows two definitions of class A: $ g++ -E main-unguarded.cpp In the cpp-article/hello-world directory, there is a “hello-world.cpp” example file: #include To obtain that translation unit (the preprocessed source code), the -E option can be passed to the g++ compiler, along with the -o option to specify the desired name of the preprocessed source file. Once the preprocessor finishes creating that (sometimes huge) translation unit, the compiler starts the compilation phase and produces the object file. It’ll also do some other tasks like macro replacements.

Source files, on the other hand, are opened only once by the compiler (and preprocessor), when they are passed to it.įor each C++ source file, the preprocessor will build a translation unit by inserting content in it when it finds an #include directive at the same time that it’ll be stripping code out of the source file and of the headers when it finds conditional compilation blocks whose directive evaluates to false. Instead, they are included from source files.Įach header file can be opened multiple times during the preprocessing phase of all source files, depending on how many source files include them, or how many other header files that are included from source files also include them (there can be many levels of indirection). Header files aren’t passed to the compiler. Only source files are passed to the compiler (to preprocess and compile it). The first step that the compiler will do on a source file is run the preprocessor on it. The extension doesn’t matter for the C++ preprocessor, which will literally replace the line containing the #include directive with the entire content of the included file. hxx, or have no extension at all like in the C++ standard library and other libraries’ header files (like Qt).

cc extension suffixes.Ī C++ source file can include other files, known as header files, with the #include directive.

The object files resulting from the compilation of multiple source files are then linked into an executable, a shared library, or a static library (the last of these being just an archive of object files). The Build Pipeline: Preprocess, Compile, and LinkĮach C++ source file needs to be compiled into an object file.

The source files provided should be portable to other operating systems, although the Makefiles accompanying them for the automated build process should be portable only to Unix-like systems.

The examples were compiled in a CentOS Linux machine: $ uname -sr

Note: This article has some example source code that can be downloaded from The article will explain how a C++ compiler works with some of the basic language constructs, answer some common questions that are related to their processes, and help you work around some related mistakes that developers often make in C++ development. In this article, you will learn exactly that. Whether you are designing a C++ application, implementing new features for it, trying to address bugs (especially certain strange bugs), or trying to make C and C++ code work together, knowing how compilation and linking works will save you a lot of time and make those tasks much more pleasant. Why is C++ source code split into header and source files? How is each part seen by the compiler? How does that affect compilation and linking? There are many more questions like these that you may have thought about but have come to accept as convention.

Compilation and linking are two very basic processes that happen all the time during C++ software development, but oddly enough, they aren’t well understood by many C++ developers. That chapter, in 2.2, mentions in half a page the compilation and linking process in C++.

Bjarne Stroustrup’s The C++ Programming Language has a chapter titled “A Tour of C++: The Basics”-Standard C++.
