# Building Eden

> [!WARNING]
> This guide is intended for developers ONLY. If you are not a developer or packager, you are unlikely to receive support.

This is a full-fledged guide to build Eden on all supported platforms.

## Dependencies
First, you must [install some dependencies](Deps.md).

## Clone
Next, you will want to clone Eden via the terminal:

```sh
git clone https://git.eden-emu.dev/eden-emu/eden.git
cd eden
```

Or use Qt Creator (Create Project -> Import Project -> Git Clone).

## Android

Android has a completely different build process than other platforms. See its [dedicated page](build/Android.md).

## Initial Configuration

If the configure phase fails, see the `Troubleshooting` section below. Usually, as long as you followed the dependencies guide, the defaults *should* successfully configure and build.

### Option A: Qt Creator

This is the recommended GUI method for Linux, macOS, and Windows.

<details>
<summary>Click to Open</summary>

> [!WARNING]
> On MSYS2, to use Qt Creator you are recommended to *also* install Qt from the online installer, ensuring to select the "MinGW" version.

Open the CMakeLists.txt file in your cloned directory via File -> Open File or Project (Ctrl+O), if you didn't clone Eden via the project import tool.

Select your desired "kit" (usually, the default is okay). RelWithDebInfo or Release is recommended:

Hit "Configure Project", then wait for CMake to finish configuring (may take a while on Windows).

### Option B: Command Line

> [!WARNING]
>For all systems:
>- *CMake* **MUST** be in your PATH (and also *ninja*, if you are using it as `<GENERATOR>`)
>- You *MUST* be in the cloned *Eden* directory
>
>On Windows:
>  - It's recommended to install **[Ninja](https://ninja-build.org/)**
>  - You must load **Visual C++ development environment**, this can be done by running our convenience script:
>    - `tools/windows/load-msvc-env.ps1`
>  - If you're using CCache:
>    - You need to add the environment variable `CL` with the `/FS` flag (`set CL=/FS`)
>    - Build may fail cause multiple cl instaces are trying to write to the same file (and Windows can't do it nicely), just hit "Build" again (you may need to do it a few times)

Availables `<GENERATOR>`:
- MSYS2: `MSYS Makefiles`
- MSVC: `Ninja` (preferred) or `Visual Studio 17 2022`
- macOS: `Ninja` (preferred) or `Xcode`
- Others: `Ninja` (preferred) or `UNIX Makefiles`

Availables `<BUILD_TYPE>`:
- `Release` (default)
- `RelWithDebInfo` (debug symbols--compiled executable will be large)
- `Debug` (if you are using a debugger and annoyed with stuff getting optimized out)

Also see the [Options](Options.md) page for additional CMake options.

```sh
cmake -S . -B build -G "<GENERATOR>" -DCMAKE_BUILD_TYPE=<BUILD_TYPE> -DYUZU_TESTS=OFF
```

If you are on Windows and prefer to use Clang:

```sh
cmake -S . -B build -G "<GENERATOR>" -DCMAKE_C_COMPILER=clang-cl -DCMAKE_CXX_COMPILER=clang-cl
```

### Building & Setup

* Once Cloned, You will be taken to a prompt like the image below:

<img src="https://user-images.githubusercontent.com/42481638/216899092-3fe4cec6-a540-44e3-9e1e-3de9c2fffc2f.png" width="500">

* Set the settings to the image below:
* Change `Build type: Release`
* Change `Name: Release`
* Change `Toolchain Visual Studio`
* Change `Generator: Let CMake decide`
* Change `Build directory: build`

<img src="https://user-images.githubusercontent.com/42481638/216899164-6cee8482-3d59-428f-b1bc-e6dc793c9b20.png" width="500">

* Click OK; now Clion will build a directory and index your code to allow for IntelliSense. Please be patient.
* Once this process has been completed (No loading bar bottom right), you can now build eden
* In the top right, click on the drop-down menu, select all configurations, then select eden

* Now run by clicking the play button or pressing Shift+F10, and eden will auto-launch once built.

## Troubleshooting

If your initial configure failed:
- *Carefully* re-read the [dependencies guide](Deps.md)
- Clear the CPM cache (`.cache/cpm`) and CMake cache (`<build directory>/CMakeCache.txt`)
- Evaluate the error and find any related settings
- See the [CPM docs](CPM.md) to see if you may need to forcefully bundle any packages

Otherwise, feel free to ask for help in Revolt or Discord.

## Caveats

Many platforms have quirks, bugs, and other fun stuff that may cause issues when building OR running. See the [Caveats page](Caveats.md) before continuing.

## Building & Running

### On Qt Creator

Simply hit Ctrl+B, or the "hammer" icon in the bottom left. To run, hit the "play" icon, or Ctrl+R.

### On Command Line

If you are using the `UNIX Makefiles` or `Visual Studio 17 2022` as `<GENERATOR>`, you must also want to add `--parallel $(nproc)` to this command to improve building time.

```
cmake --build build
```

Your compiled executable will be in:
- `build/bin/eden.exe` for Windows,
- `build/bin/eden.app/Contents/MacOS/eden` for macOS,
- and `build/bin/eden` for others.

## Scripts

Some platforms have convenience scripts provided for building.

- **[Linux](scripts/Linux.md)**
- **[Windows](scripts/Windows.md)**

macOS scripts will come soon.
