Chapel Prerequisites

Chapel is designed to be portable to a variety of systems and only requires software that is common on UNIX systems.

The following are prerequisites and assumptions about your environment for using Chapel:

  • You are using an environment that supports standard UNIX commands such as: cd, mkdir, rm, echo

  • You have a Bourne shell available at /bin/sh and env available at /usr/bin/env.

  • You have Python 2.7 or newer available as either python3 or python and that env can locate it.

  • You have access to gmake or a GNU-compatible version of make.

  • You have access to standard C and C++ compilers.

    • Building the Chapel compiler and bundled components requires C++14 and one of the following:

      • GCC 7.1 or newer

      • Clang 5.0 or newer

      • Apple Clang 9.3 or newer

    • C11 support, while not required, will enable faster atomic operations.

  • CMake is available and cmake runs version 3.13.4 or later.

  • The LLVM backend is now the default and it is easiest to use it with a system-wide installation of LLVM. LLVM and clang versions 11, 12, 13 and 14 are currently supported. If a system-wide installation of LLVM and clang with one of those versions is not available, you can use the bundled LLVM or disable LLVM support (see CHPL_LLVM).

In addition, several optional components have additional requirements:

  • Python 3.7 or newer is required if you want to use chpldoc, c2chapel, or Chapel’s test system. These additionally require python3-devel or the equivalent package; python3 and pip3 commands; and the venv Python package.

  • doxygen 1.8.17 or newer is required to build the complete documentation

  • m4 is required for building the bundled GMP

  • git is required for Mason, chapel’s package manager

  • pkg-config is required for the mason system subcommands
