The way to Set up a C Compiler on Linux

Whether you're coding in C or building a Linux program from source code, you'll need to install a C compiler. The two most important on Linux are the venerable GCC and the newer Clang.

This is how you can install both on your computer.

Install GCC on Linux

GCC, or the GNU Compiler Collection, has existed since the 1980s and is older than Linux itself. It not only compiles C programs, but also processes C ++, Objective-C, Objective-C ++, Fortran, ADA and Go. Many open source projects still rely on it, including the Linux kernel.

To install GCC along with the required C libraries on Debian and Ubuntu, install the essential to construction Package:

sudo apt install build-essential

On Fedora and other RPM-based distributions:

sudo dnf install gcc

And on Arch Linux:

sudo pacman -S gcc

For any other distribution, you can usually search for "GCC" and find a package for your system. This also applies to clang.

To create a simple C program like the famous "Hello, World!" To compile, just go to the directory where you saved it and run the following command:

gcc hello.c

…Where Hello c is the name of your program.

If the program is correct, GCC will output the compiled file as a a.out in the current directory. Enter the following to run it:

./a.out

Install Clang on Linux

The newer kid on the block is the Clang compiler, which was developed by Apple, ARM, Sony, AMD, and others as the front line to the LLVM compiler. Apple uses it as a compiler for its Xcode development environment for macOS.

Clang aims to be compatible with GCC while increasing performance. It's popular because it's licensed under the Apache 2.0 license that doesn't require developers to release their source code when they make changes.

You can install Clang using your package manager. On Debian and Ubuntu, just install the ring Package:

sudo apt install clang

On Fedora / CentOS:

sudo dnf install clang

To install Clang on Arch-based distributions:

sudo pacman -S clang

Compiling works the same way as with GCC:

hello.c. ring
