Requirements

Network access

The source tree vendors most dependencies when it can. Network access is rarely required.

The main exception is a Windows build that cannot find a working SDL3 install. In that case the build may download SDL3.

You also need network access to clone the repository.

Software

  • A C++20 compiler. You may hit issues on platforms that lack fixed-width integers in the standard library (see cppreference for cstdint).
  • A C99 compiler. Many dependencies are C and must be compiled as C. Building them with a C++ compiler is not guaranteed to work.
  • CMake 3.15 or newer, plus a working generator backend (Visual Studio, GNU make, or any other backend CMake supports).
  • Python 3.x for internal scripts.
  • A text editor. Visual Studio Code works. Use whatever editor you prefer.

Brains

Know modern C++20 features and prefer them over older patterns when they fit. Many old undefined-behaviour tricks are now standard. For example, bit-casting float to std::uint32_t uses std::bit_cast instead of union hacks or reinterpret_cast.

Test your code. Blind coding and hope are not a substitute for checks.
