# Building melonDS

|

* [Windows](#windows)
|
|
* [macOS](#macos)
|
|
|
|
## 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 melonDS repository and prepare:
|
|
```bash
|
|
git clone https://github.com/melonDS-emu/melonDS
|
|
cd melonDS
|
|
```
|
|
3. Compile:
|
|
```bash
|
|
cmake -B build
|
|
cmake --build build -j$(nproc --all)
|
|
```
|
|
|
|
## Windows
|
|
1. Install [MSYS2](https://www.msys2.org/)
|
|
2. Open the MSYS2 terminal from the Start menu:
|
|
* For x64 systems (most common), use **MSYS2 UCRT64**
|
|
* For ARM64 systems, use **MSYS2 CLANGARM64**
|
|
3. Update the packages using `pacman -Syu` and reopen the same terminal if it asks you to
|
|
4. Install git and clone the repository
|
|
```bash
|
|
pacman -S git
|
|
git clone https://github.com/melonDS-emu/melonDS
|
|
cd melonDS
|
|
```
|
|
5. Install dependencies:
|
|
Replace `<prefix>` below with `mingw-w64-ucrt-x86_64` on x64 systems, or `mingw-w64-clang-aarch64` on ARM64 systems.
|
|
```bash
|
|
pacman -S <prefix>-{toolchain,cmake,SDL2,libarchive,enet,zstd}
|
|
```
|
|
6. Install Qt and configure the build directory
|
|
* Dynamic builds (with DLLs)
|
|
1. Install Qt: `pacman -S <prefix>-{qt6-base,qt6-svg,qt6-multimedia,qt6-svg,qt6-tools}`
|
|
2. Set up the build directory with `cmake -B build`
|
|
* Static builds (without DLLs, standalone executable)
|
|
1. Install Qt: `pacman -S <prefix>-qt5-static`
|
|
(Note: As of writing, the `qt6-static` package does not work.)
|
|
2. Set up the build directory with `cmake -B build -DBUILD_STATIC=ON -DUSE_QT6=OFF -DCMAKE_PREFIX_PATH=$MSYSTEM_PREFIX/qt5-static`
|
|
7. Compile: `cmake --build build`
|
|
|
|
If everything went well, melonDS 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](https://brew.sh)
|
|
2. Install dependencies: `brew install git pkg-config cmake sdl2 qt@6 libarchive enet zstd`
|
|
3. Download the melonDS repository and prepare:
|
|
```zsh
|
|
git clone https://github.com/melonDS-emu/melonDS
|
|
cd melonDS
|
|
```
|
|
4. Compile:
|
|
```zsh
|
|
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, melonDS.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.
|
|
|
|
## Nix (macOS/Linux)
|
|
|
|
melonDS provides a Nix flake with support for both macOS and Linux. The [Nix package manager](https://nixos.org) needs to be installed to use it.
|
|
|
|
* To run melonDS, just type `nix run github:melonDS-emu/melonDS`.
|
|
* To get a shell for development, clone the melonDS repository and type `nix develop` in its directory.
