This guide explains how to set up FreeRTOS on Linux, macOS, and Windows. Follow the instructions carefully based on your operating system.

You can use VS Code as the IDE for editing and working with the FreeRTOS code.

To check if GCC is installed on your system, open the terminal and run the following command:

gcc --version

If GCC is not installed, or the command is not found, follow the steps below to install it. Install GCC Update your package lists, upgrade existing packages, and install GCC with the following commands:

sudo apt update
sudo apt upgrade
sudo apt install build-essential

After installing GCC, navigate to the FreeRTOS demo directory for the Posix example:

cd FreeRTOS/Demo/Posix_GCC

Run the following command to compile the demo:

make

If there are no errors, a build directory will be created, and inside it, you will find the executable file posix_demo.

Download and install Visual Studio Community 2022(https://visualstudio.microsoft.com/)

During installation, ensure the following option is selected: Desktop Development with C

In the "Individual Components" section, make sure to check:

• MSVS v142 - VS 2019 C x64/x86 build tools (v14.29-16.11)
• MSVS v142 - VS 2019 C x64/x86 Spectre-mitigated libraries (v14.29-16.11)

After installation, navigate to the following directory:

FreeRTOS/Demo/WIN32-MSVC

Open the solution file WIN32.sln by double-clicking it.

You can now compile the FreeRTOS demo in Visual Studio by building the solution.

Files for this example can be found in the QueFiles branch.

More examples are available in the exercise materials.

For Linux/macOS, if you encounter errors while running make, ensure all required dependencies are installed. For Windows, make sure that Visual Studio is fully updated and has all the necessary components selected for C development.
