To install the GNU GCC compiler and development environment on Debian Linux, you can use the apt-get command to install the build-essential package, which includes the GCC compiler and a set of libraries and tools required for development.
To install the build-essential package, open a terminal and run the following command:
sudo apt-get update sudo apt-get install build-essential
This will install the GCC compiler and the required libraries and tools.
If you need to install a specific version of GCC, you can use the apt-get command to install the gcc package followed by the desired version number. For example, to install GCC 9.3, you can use the following command:
sudo apt-get update sudo apt-get install gcc-9
This will install GCC 9 and its dependencies.
You can also use the apt-get command to install other development tools and libraries, such as the make utility, the gdb debugger, and the openssl library.
For example, to install the make utility, you can use the following command:
sudo apt-get update sudo apt-get install make
Keep in mind that the apt-get command will only install packages from the default repositories configured on your system. If you need to install packages from a specific repository or from a local package file, you may need to use other tools such as apt-add-repository or dpkg.
