Building KH Melon Mix

Linux

  1. Install dependencies:
    • Ubuntu:
      • All versions: sudo apt install cmake extra-cmake-modules libcurl4-gnutls-dev libpcap0.8-dev libsdl2-dev libarchive-dev libenet-dev libzstd-dev
      • 24.04: sudo apt install qt6-{base,base-private,multimedia,svg}-dev
      • 22.04: sudo apt install qtbase6-dev qtbase6-private-dev qtmultimedia6-dev libqt6svg6-dev
      • Older versions: sudo apt install qtbase5-dev qtbase5-private-dev qtmultimedia5-dev libqt5svg5-dev
        Also add -DUSE_QT6=OFF to the first CMake command below.
    • Fedora: sudo dnf install gcc-c++ cmake extra-cmake-modules SDL2-devel libarchive-devel enet-devel libzstd-devel qt6-{qtbase,qtbase-private,qtmultimedia,qtsvg}-devel wayland-devel
    • Arch Linux: sudo pacman -S base-devel cmake extra-cmake-modules git libpcap sdl2 qt6-{base,multimedia,svg} libarchive enet zstd
  2. Download the KH Melon Mix repository and prepare:
    git clone https://github.com/vitor251093/KHMelonMix
    cd KHMelonMix
  3. Compile:
    cmake -B build
    cmake --build build -j$(nproc --all)

Windows

  1. Install MSYS2
  2. Open the MSYS2 terminal from the Start menu:
    • For x64 systems (most common), use MSYS2 UCRT64
    • For ARM64 systems, use MSYS2 CLANGARM64
  3. Update the packages using pacman -Syu and reopen the same terminal if it asks you to
  4. Install git and clone the repository
    pacman -S git
    git clone https://github.com/vitor251093/KHMelonMix
    cd KHMelonMix
  5. Install dependencies:
    Replace <prefix> below with mingw-w64-ucrt-x86_64 on x64 systems, or mingw-w64-clang-aarch64 on ARM64 systems.
    pacman -S <prefix>-{toolchain,cmake,SDL2,libarchive,enet,zstd}
  6. Install Qt and configure the build directory
    • Dynamic builds (with DLLs)
      1. Install Qt: pacman -S <prefix>-{qt6-base,qt6-svg,qt6-multimedia,qt6-svg,qt6-tools}
      2. Set up the build directory with cmake -B build
    • Static builds (without DLLs, standalone executable)
      1. Install Qt: pacman -S <prefix>-qt5-static
        (Note: As of writing, the qt6-static package does not work.)
      2. Set up the build directory with cmake -B build -DBUILD_STATIC=ON -DUSE_QT6=OFF -DCMAKE_PREFIX_PATH=$MSYSTEM_PREFIX/qt5-static
  7. Compile: cmake --build build

If everything went well, KH Melon Mix should now be in the build folder. For dynamic builds, you may need to run melonDS from the MSYS2 terminal in order for it to find the required DLLs.

macOS

  1. Install the Homebrew Package Manager
  2. Install dependencies: brew install git pkg-config cmake sdl2 qt@6 libarchive enet zstd
  3. Download the KH Melon Mix repository and prepare:
    git clone https://github.com/vitor251093/KHMelonMix
    cd KHMelonMix
  4. Compile:
    cmake -B build -DCMAKE_PREFIX_PATH="$(brew --prefix qt@6);$(brew --prefix libarchive)"
    cmake --build build -j$(sysctl -n hw.logicalcpu)

If everything went well, MelonMix.app should now be in the build directory.

Self-contained app bundle

If you want an app bundle that can be distributed to other computers without needing to install dependencies through Homebrew, you can additionally run ../tools/mac-libs.rb . after the build is completed, or add -DMACOS_BUNDLE_LIBS=ON to the first CMake command.
