Popular C++ Compilers – Installation and Usage on Windows, Linux, and macOS

C++ remains one of the most widely-used programming languages, powering a wide range of applications from system-level software to large-scale game development. One crucial component of writing and running C++ programs is the compiler. In this guide, we’ll explore the most popular C++ compilers available for Windows, Linux, and macOS, along with instructions on how to download, install, and use them.

1. GCC (GNU Compiler Collection)

GCC is a free and open-source compiler system that supports several programming languages, including C, C++, and Fortran. It is available for all major platforms, including Windows, Linux, and macOS.

Installation Instructions:

For Linux:

Most Linux distributions come with GCC pre-installed. To check if it’s already installed, open the terminal and type:


gcc --version

If GCC is not installed, you can install it by running:


sudo apt update
sudo apt install build-essential

This installs GCC, g++ (C++ compiler), and other necessary development tools.

For Windows:

To use GCC on Windows, you can download the MinGW-w64 package. Follow these steps:

Download the installer from the official MinGW-w64 project.
Run the installer and select the architecture you want (32-bit or 64-bit).
Follow the installation instructions and add MinGW-w64 to the system PATH variable.
Verify the installation by typing the following in

Command Prompt

:
```
gcc --version
```

For macOS:

You can install GCC on macOS using Homebrew:

Install

Homebrew

if it’s not installed by running this command in the terminal:


/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Install GCC using the following command:
```
brew install gcc
```

How to Use:

Once installed, you can compile your C++ code by using the following command:


g++ -o output_filename source_file.cpp

For example:


g++ -o myprogram main.cpp

2. Clang (LLVM Project)

Clang is another open-source compiler for C, C++, and other languages, built on top of the LLVM project. Clang is known for producing highly optimized code, fast compilation times, and superior diagnostics.

Installation Instructions:

For Linux:

Clang is available in most package managers. To install Clang on Ubuntu:


sudo apt update
sudo apt install clang

For Windows:

To install Clang on Windows, follow these steps:

Download the LLVM installer from the LLVM website.
Run the installer and choose the components you want.
Ensure that LLVM binaries are added to the system PATH.
Verify installation by typing:
```
clang --version
```

For macOS:

On macOS, Clang is included in Xcode. You can install Xcode’s Command Line Tools with:


xcode-select --install

How to Use:

To compile C++ code with Clang:


clang++ -o output_filename source_file.cpp

For example:


clang++ -o myprogram main.cpp

3. MSVC (Microsoft Visual C++)

MSVC is the Microsoft C++ compiler included in Visual Studio. It is the preferred compiler for Windows development and is widely used in commercial applications.

Installation Instructions:

For Windows:

Download Visual Studio from the official Visual Studio website.
During installation, make sure to select the Desktop development with C++ workload.
Once installed, open Visual Studio and start a new C++ project.

For Linux and macOS:

While MSVC itself is not directly available on Linux and macOS, you can use CMake or cross-compilation tools to compile code written for MSVC. Additionally, Visual Studio Code can be used on Linux/macOS for development.

How to Use:

To compile code in Visual Studio:

Open Visual Studio.
Create a new project or open an existing C++ project.
Build the project by selecting Build > Build Solution or pressing Ctrl+Shift+B.

Alternatively, you can compile C++ code using the Developer Command Prompt for Visual Studio:


cl source_file.cpp

4. Intel C++ Compiler (ICC)

Intel C++ Compiler is a high-performance compiler from Intel, designed for use in both Windows and Linux. It is known for producing highly optimized code for Intel processors.

Installation Instructions:

For Linux:

You can download and install the Intel OneAPI toolkit, which includes the ICC compiler. Follow these steps:

Go to the Intel OneAPI Toolkit website and download the installer.
Follow the instructions for installation on Linux.

For Windows:

Download the Intel OneAPI Base Toolkit from the Intel website.
Install the toolkit and ensure that ICC is selected during installation.

For macOS:

Intel C++ Compiler does not directly support macOS, but you can use GCC or Clang for development on macOS.

How to Use:

Once installed, you can compile your C++ code with:


icpc -o output_filename source_file.cpp

For example:


icpc -o myprogram main.cpp

5. Mingw-w64

MinGW-w64 is an alternative compiler for Windows that provides a native Windows build of GCC. It is particularly useful for Windows developers who prefer using GCC.

Installation Instructions:

For Windows:

Download MinGW-w64 from the official website.
Install the package and add MinGW to your system PATH.
Verify installation with:


gcc --version

How to Use:

Compile C++ code with:


g++ -o output_filename source_file.cpp

For example:


g++ -o myprogram main.cpp
