gitare the packages we are installing.
Step 2: Creating a Build Directory
Next, we will create a directory where we will build our driver. Run the following commands:
mkdir -p ~/build
mkdiris the command to make a directory.
-pis a parameter that tells mkdir to create parent directories as needed.
~/buildis the directory we are creating.
cdis the command to change the current directory.
Step 3: Cloning the Driver Repository
Now, we will clone the rtl8821CU driver repository from GitHub using the following command:
