Preparing the System to Install GCC
Before installing GCC compiler, it is important to prepare your Ubuntu system, ensuring that all packages are up-to-date. In this section, we will discuss the steps required to update and upgrade your Ubuntu system.
- Check the version of Ubuntu
Before updating or upgrading your Ubuntu system, it is recommended to check the version of Ubuntu you are currently running. To do this, open the terminal and type the following command:
lsb_release -a
This will display the version of Ubuntu you are running along with other details.
- Update the system
Once you have checked the version of Ubuntu, the next step is to update the system. Updating the system ensures that the Ubuntu package list is up-to-date. To update the system, type the following command in the terminal:
sudo apt update
- Upgrade the system
After updating the system, the next step is to upgrade the system. Upgrading the system ensures that all installed packages are up-to-date. To upgrade the system, type the following command in the terminal:
sudo apt upgrade
The upgrade process may take some time depending on the number of packages that need to be upgraded. Once the upgrade process is complete, your Ubuntu system is ready to install GCC compiler.
Installing GCC Compiler
GCC compiler is an essential tool for developers who want to compile C code on Ubuntu. In this section, we will discuss the steps required to install GCC compiler on your Ubuntu system.
- Use the command ‘sudo apt install gcc’ to install GCC compiler
According to Learn Ubuntu, to install GCC compiler on your Ubuntu system, open the terminal and type the following command:
sudo apt install gcc
This will install the GCC compiler on your system. If you want to install the G++ compiler as well, you can use the following command:
sudo apt install g++
- Verify the installation by checking the version of GCC
Once the installation is complete, you can verify the installation by checking the version of GCC. To check the version of GCC, type the following command in the terminal:
gcc –version
This will display the version of GCC installed on your Ubuntu system.
Congratulations, you have successfully installed GCC compiler on your Ubuntu system. In the next section, we will discuss the importance of the build-essential package and how to install it.
Installing Build-Essential Package
The build-essential package is a collection of essential software packages required for building and compiling software on Ubuntu. In this section, we will discuss the steps required to install the build-essential package.
- Use the command ‘sudo apt install build-essential’ to install build-essential package
According to Learn Ubuntu, to install the build-essential package, open the terminal and type the following command:
sudo apt install build-essential
This will install the build-essential package along with other necessary utilities for compiling software.
- Explain the importance of build-essential package
The build-essential package provides a set of essential software packages that are required for building and compiling software on Ubuntu. This package includes GCC, G++, make, and dpkg-dev. These packages are essential for compiling a whole project and should be installed if you plan to compile C or C++ code on Ubuntu.
Congratulations, you have successfully installed the build-essential package on your Ubuntu system. In the next section, we will discuss how to compile and run a basic C program using GCC compiler.
Compiling and Running a Basic C Program
In this section, we will discuss how to compile and run a basic C program using GCC compiler.
- Write a basic C program using any editor of your choice
To compile and run a C program, you need to first write a basic C program. You can use any editor of your choice to write the program. For this example, let’s use the nano editor. Open the terminal and type the following command:
nano hello.c
This will open the nano editor with a new file named hello.c. Type the following code in the editor:
“`
#include
int main() {
printf(“Hello, World!”);
return 0;
}
“`
Once you have typed the code, save the file and exit the editor.
- Compile the program using the command ‘gcc filename.c -o outputfilename’
According to Linuxize, to compile the C program, open the terminal and type the following command:
gcc hello.c -o hello
This will compile the C program and generate an output file named hello.
- Run the program using the command ‘./outputfilename’
To run the program, type the following command in the terminal:
./hello
This will display the output “Hello, World!” in the terminal.
Congratulations, you have successfully compiled and run a basic C program using GCC compiler. In the next section, we will discuss how to install multiple versions of GCC compiler.
Installing Multiple Versions of GCC Compiler
In this section, we will discuss how to install multiple versions of GCC compiler on your Ubuntu system.
- Add the PPA for Ubuntu Toolchain
According to LinuxConfig, to install multiple versions of GCC compiler, you need to add the PPA for Ubuntu Toolchain. Open the terminal and type the following command:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
- Update the package list and install the desired GCC version
Once you have added the PPA for Ubuntu Toolchain, you need to update the package list and install the desired version of GCC. To do this, type the following commands in the terminal:
sudo apt update
sudo apt install gcc-<version> g++-<version>
Replace <version>
with the desired version of GCC. For example, if you want to install GCC version 6, you would type:
sudo apt install gcc-6 g++-6
- Verify the installation by checking the version of GCC
Once you have installed the desired version of GCC, you can verify the installation by checking the version of GCC. To check the version of GCC, type the following command in the terminal:
gcc –version
This will display the version of GCC installed on your Ubuntu system.
Congratulations, you have successfully installed multiple versions of GCC compiler on your Ubuntu system. In the next section, we will provide some final thoughts on installing GCC compiler on Ubuntu.
