A Comprehensive Guide to Installing GCC on Ubuntu 22.04

The GNU Compiler Collection, commonly known as GCC, is a key tool in software development. It supports a wide range of programming languages and has played a significant role in the growth of open-source software.

This guide will walk you through installing GCC on Ubuntu 22.04, also known as Jammy Jellyfish.

Overview of GCC

GCC is available across various operating systems, including Linux, Windows, and macOS. It supports multiple programming languages such as C, C++, Objective-C, Fortran, and even newer languages like Go. With GCC, developers can utilize different code optimization levels to ensure their applications are efficient and resource-conservative.

GCC also offers language extensions that allow developers to create powerful applications. The GCC ecosystem is supported by a dynamic community that continuously contributes to keeping GCC up-to-date with emerging language standards.

Creating a C Program on Ubuntu 22.04

After the installation, it’s time to check if the compiler is functioning as expected. This can be done by creating a basic C program. For example, we can create a straightforward “this is net2” C program using the nano editor and save the file as thisisnet2.c.

#include

int main() {

printf(“thisisnet2n”);

return 0;

}

Save this document and transform it into an executable file.

gcc -o thisisnet2 thisisnet2.c

This command will create a binary file named ‘thisisnet2’ in the current directory. To run the program, use the following command:

The C program has been executed without any issues. GCC has been installed successfully on your Ubuntu 22.04 system.
