Compiler Requirements

Before installing COMPAS CGAL, you need to ensure you have the appropriate C++ compiler setup for your operating system:

Windows

  • Install Visual Studio Build Tools (2022 or newer)

  • During installation, select “Desktop development with C++”

  • No additional PATH settings are required as CMake will automatically find the compiler

macOS

  • Install Xcode Command Line Tools:

    xcode-select --install

  • The clang compiler will be automatically available after installation

Linux

  • Install GCC and related build tools. On Ubuntu/Debian:

    sudo apt-get update
sudo apt-get install build-essential

  • On RHEL/Fedora:

    sudo dnf groupinstall "Development Tools"

  • Alternatively, when using conda, you can install the C++ compiler through conda:

    conda install gxx_linux-64
