In order to let make know what to do, you need to create a file named Makefile in the root of your project. Then it automatically keeps track of which dependencies have changed and recompiles only the necessary parts. make lets you define your target, and how to reach the target and what are the dependencies. But keeping track of what has changed manually is also a difficult task. But if some of the source files haven’t been modified since the last compilation, it’s a waste of time and resources to compile all the files. Also, the compilation command will compile all of the source files every time it is executed. The resultant command is likely massive and difficult to remember and type. Moreover, if your code uses any library, you need to list those libraries, too. If you have more files, then you need to list all of them, while taking care to set the correct include paths and library paths. Here, I show you how to install the GNU toolchain for some famous distributions.įor Ubuntu, you need to run the following command: GCC is one of the most common tools in the unix world, and is available in every single Linux distribution. I’ll touch briefly on installing for Linux, Mac, and Windows. In this tutorial, you will learn how to compile C++ programs with the g++ compiler provided by GCC, and how to use Make to automate the compilation process. You can check out the detailed standard support on gnu.org.
It also provides some GNU extensions to the standard to enable more useful features.
The g++ utility supports almost all mainstream C++ standards, including c++98, c++03, c++11, c++14, c++17, and experimentally c++20 and c++23.
The latest version as of writing this article is GCC 11.1, released April 27, 2021. GCC now supports many languages, including C++, Objective C, Java, Fortran, and Go.
GNU Compiler Collection, also known as GCC, started as a C compiler, created by Richard Stallman in 1984 as a part of his GNU project. GCC is part of the GNU toolchain, which comes with utilities like GNU make, GNU bison, and GNU AutoTools. Although there are many compilers available, GCC still ranks as one of the most popular choices for C++. C++ is one of the most dominant programming languages.
