Building Cthulhu

Prerequisites

Configuring and building Cthulhu requires the following tools:

• Meson
• Ninja
• Flex and Bison. On windows these can be acquired through Chocolatey
• A C11 compliant compiler.

Cthulhu can optionally use the following tools to enable additional features:

• Doxygen for generating documentation.
• GMP for better performance compile times.
  • Note that if libgmp is used, it must also be available at runtime.
  • The compiler contains a build time fallback implementation of GMP when it is not available at build time.
• A C++20 compiler for building the GUI tools.
  • Currently these tools are only available on Windows, and require a d3d12 capable GPU.
• A Java 8+ compiler for building the jvm driver tests and standard library.

Cthulhus current runtime dependencies are:

• GMP; only if the compiler is built with GMP support.

Configuration

All available build options are listed in the meson_options.txt file found in the projects root directory.

meson setup build
ninja -C build
ninja -C build docs # build documentation, requires doxygen
ninja -C build test # run tests

Consuming as a meson subproject

By default as a subproject the stable language drivers are built. If you want only a specific set of libraries you can disable everything with the following incantaion.

meson setup build -Dauto_features=disabled

This does not disable the targets, so they are still available by get_variable. all targets are build_by_default : false so meson will compile them on demand.
