I recently started working on some of the C and C++ related projects, but installation and compiler setup took too much time. I searched on Google related to installation but everyone told me about GCC and G++ Compiler. Also, I am a Mac user so by default Xcode came with the Clang library, But want to use it specifically GCC or G++.
As you know Jetbrains Clion IDE is not freely available. So, we developers heavily depend on VSCode. At last, I decided I had to make something that could do the setup of the C & C++ Compiler automatically.
The one thing I know is Mac supports Homebrew and it can do this thing. So, I started developing a script with basic idea called mac_script.sh
Script do-nothings, just I have to automate some things and I did. Let me share the script with you So, will get an idea of how the script works behind the scenes.
C/C++ Compiler Installation Script.
#!/bin/bash # Function to check if a command exists command_exists() { command -v "$1" >/dev/null 2>&1 } # Function to display help show_help() { echo "Usage: $0 [--help]" echo echo "This script installs Homebrew and GCC on macOS if they are not already installed." echo "It also creates a script to compile and run C/C++ code." echo echo "Options:" echo " --help Show this help message and exit" } # Check for --help argument if [ "$1" == "--help" ]; then show_help exit 0 fi # Detect the operating system OS="$(uname -s)" # Install Homebrew on macOS if not installed if [ "$OS" == "Darwin" ]; then if ! command_exists brew; then echo "Homebrew not found. Installing Homebrew..." /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" else echo "Homebrew is already installed." fi # Install GCC if not installed if ! command_exists gcc; then echo "GCC not found. Installing GCC..." brew install gcc else echo "GCC is already installed." fi # Create a script to compile and run C/C++ code cat << 'EOF' > compile_and_run.sh #!/bin/bash # Check if a file is provided if [ -z "$1" ]; then echo "Usage: $0 <source-file>" exit 1 fi # Get the file extension EXT="${1##*.}" # Compile and run based on the file extension if [ "$EXT" == "c" ]; then gcc "$1" -o "${1%.c}" && "./${1%.c}" elif [ "$EXT" == "cpp" ]; then g++ "$1" -o "${1%.cpp}" && "./${1%.cpp}" else echo "Unsupported file extension: $EXT" exit 1 fi EOF # Make the script executable chmod +x mac_script.sh echo "Script to compile and run C/C++ code has been created as mac_script.sh" # Run the compile_and_run.sh script ./mac_script.sh <source-file> else echo "This script is intended to run on macOS." exit 1 fi Let me show you. How to run this script.
Installation
To install the compiler, run the following command in the terminal:
sudo chmod -x mac_script.sh This will download the compiler and install it on your system. You may need to enter your password to allow the installation.
Usage
Once the compiler is installed, you can use it to compile and run programs. To compile a program, run the following command:
sudo mac_script.sh program.c sudo mac_script.sh program.cpp That's it!!!
Conclusion
After running the script everything worked fine as expected. Why I am sharing this is not a script. My main motto is that you can do so many things with shell or bash scripts. Just try it once, You will enjoy it. Or maybe you can contribute to this repo or just upgrade this script and make it for Windows and Linux and add more features.
