Установка gcc arch linux

Now check whether GCC is working with the following command:

Writing Your First C Program:

Now let’s write a very simple C program, which we will compile in the next section of this article below using GCC C compiler.

First, create a project directory (I am going to call it hello) with the following command:

Now navigate to the newly created directory with the following command:

Now create a new C source file (I am going to call it main.c) here with the following command:

Now open the file with any text editor (such as vim, nano, gedit, kate etc) of your choice.

To open the file with nano, run the following command:

To open the file with vim, run the following command:

To open the file with Gedit, run the following command:

To open the file with Kate, run the following command:

I am going to use Gedit text editor in this article.

Now type in the following lines and save the file.

Here, line 1 includes the stdio.h header file. It has function definition for the printf() function I used on line 4.

Every C program must have a main() function. It is the function that will get called when you run a C program. If you don’t write a main() function, you can’t run the C program. So I wrote a main() function in line 3 – line 7.

Inside the main() function, I called printf() library function in line 4 to print some text to the screen.

Finally, in line 6, I returned 0 from the program. On Linux world, when a program returns 0, it means the program ran successfully. You can return any integer you like but there are some Linux specific rules on what return value means what.

In the next section, I will show you how to compile the C program with GCC and run it.

Compiling and Running C Programs with GCC:

The command to compile a C source file with GCC is:

NOTE: Here, SOURCE_FILES is a whitespace separated list of C source files. The compiled executable file will be saved as OUTPUT_BINARY in your current working directory.

In our case, the main.c source file doesn’t depend on other C source file, so we can compile it with the following command:

The source file main.c should be compiled and hello executable file should be created as you can see in the screenshot below.

Now, you can run the hello executable binary file as follows:

As you can see, the correct output is printed on the screen.

So that’s basically how you use GCC to compile C programs on Linux. Thanks for reading this article.

How to Install GCC for Arch Linux

GCC (GNU Compiler Collection) comprises compilers for well-known programming languages such as C, C++, Go, Fortran, Objective-C, and many more. The GCC is completely free and provides cross-platform support for Linux, Windows, and multiple BSD-based systems.

Apart from this, one can suggest or make enhancements to GCC and you can utilize the enhancements done by other developers/users as well. Moreover, the GCC can be used to make executable files for other systems which makes it the best choice for embedded systems (as they don’t have any compiler).

Keeping in view the importance of GCC, this guide demonstrates the step-by-step procedure to install GCC on Arch Linux.

How to install GCC on Arch Linux

The GCC is available on the official repository of Arch, thus the Arch package manager can be used to install it.

Step 1: First, synchronize and update the package’s database using the following command.

Step 2 (optional): After synchronizing the database, you can look for the availability of GCC on Arch Linux by using the following command.

The output shows the dependencies that are available on the official repository of Arch Linux.

Step 3: Install GCC on Arch Linux by issuing the following command in the terminal.

Once installed successfully, verify its version by issuing the following command.

How to install older versions of GCC on Arch Linux

What if you have created a project using an old version of GCC and you are unable to compile it? For this, you may need older versions.

The older versions can be obtained easily from AUR (Arch User Repository) and to access it, you may need an AUR helper (yay, pacaur)To do so, you can make use of any AUR helper (pacaur, yay,).

For instance, the command written below will install “gcc 4.9” on your Arch Linux system.

How to remove GCC on Arch Linux

The GCC can be removed from your Arch Linux system by providing the following command.

However, you can use the -Rcnu flag to remove GCC and the unnecessary dependencies as well. In our case, the following command would remove GCC and all its dependencies.

The output shows that the gcc and all its dependencies have been removed successfully.

Conclusion

GCC (GNU Compiler Collection) is a resourceful compiler that can be obtained on Arch Linux with the help of a package manager of Arch Linux. GCC provides front ends for various programming languages such as C, C++, Go, Fortran, and many more. This guide demonstrates the way to install the latest release as well as any older version of GCC on Arch Linux.

How to Install GCC in Arch Linux

GCC is an abbreviation for GNU Compiler Collection. Most languages used to build the Linux kernel are C and object-oriented programming languages. In this article, we will discuss how to install GCC in Arch Linux.

Overview

The creators of the Linux kernel had to construct a free and open-source compiler in order to produce the kernel and modules. The GNU project is the one behind the creation of the GCC compiler. It comes pre-installed with the operating system in all current Linux distributions. The GCC compiler can be used to compile object-oriented programming languages, C, C++, Ada, Go, and a few others. You can use the GCC compiler on a Linux machine to compile code on your terminal shell.

Compilers for popular programming languages like Fortran, Objective-C, Ada, and many more are included in the GCC (GNU Compiler Collection). The GCC offers cross-platform compatibility for Linux, Windows, and many BSD-based platforms and is totally free.

In addition, anyone can recommend or add improvements to GCC, and you can use the improvements made by other users or developers. It is also the ideal option for embedded systems (since they lack a compiler) because it may be used to create executable files for other systems.

Given the significance of GCC, this post walks readers through the step-by-step process of installing GCC on Arch Linux.

How to Install GCC in Arch Linux

Check GCC Version

You must determine whether the GCC compiler is already installed on your Linux system before proceeding to install it. Use the command below to check and see if it is, and what the version is, if ever it is already installed.

Как установить GCC для Arch Linux?

Советы и хитрости

GCC (GNU Compiler Collection) включает компиляторы для известных языков программирования, таких как C, C++, Go, Fortran, Objective-C и многих других. GCC полностью бесплатен и обеспечивает кроссплатформенную поддержку для Linux, Windows и нескольких систем на базе BSD.

Кроме того, можно предлагать или вносить улучшения в GCC, а также использовать улучшения, сделанные другими разработчиками/пользователями. Кроме того, GCC можно использовать для создания исполняемых файлов для других систем, что делает его лучшим выбором для встраиваемых систем (поскольку у них нет компилятора).

Учитывая важность GCC, в этом руководстве демонстрируется пошаговая процедура установки GCC в Arch Linux.

Как установить GCC на Arch Linux
