On Windows, all library dependencies are automatically included within the `externals` folder, or can be downloaded on-demand. To build Eden, you need to install:
---
* **[Visual Studio 2022 Community](https://visualstudio.microsoft.com/downloads/)** - **Make sure to select C++ support in the installer. Make sure to update to the latest version if already installed.**
* **[CMake](https://cmake.org/download/)** - Used to generate Visual Studio project files. Does not matter if either 32-bit or 64-bit version is installed.
* **[Vulkan SDK](https://vulkan.lunarg.com/sdk/home#windows)** - **Make sure to select Latest SDK.**
- A convenience script to install the latest SDK is provided in `.ci\windows\install-vulkan-sdk.ps1`.

## Minimal Dependencies
* **Git** - We recommend [Git for Windows](https://gitforwindows.org).
On Windows, **all** library dependencies are **automatically included** within the `externals` folder.

You still need to install:
* While installing Git Bash, you should tell it to include Git in your system path. (Choose the "Git from the command line and also from 3rd-party software" option.) If you missed that, don't worry, you'll just have to manually tell CMake where your git.exe is, since it's used to include version info into the built executable.
* **[CMake](https://cmake.org/download/)** - Used to generate Visual Studio project files.
* **[Vulkan SDK](https://vulkan.lunarg.com/sdk/home#windows)** - Make sure to select **Latest SDK**.

* *A convenience script to install the latest SDK is provided in `.ci/windows/install-vulkan-sdk.ps1`*
* **[Git for Windows](https://gitforwindows.org)** - We recommend installing Git for command line use and version control integration.
* *While installing Git Bash, select "Git from the command line and also from 3rd-party software". If missed, manually set `git.exe` path in CMake.*

* *(Note: eden by default downloads to `C:\Users\<user-name>\eden` (Master)
## ⚡ Method I: MSVC Build for Windows
### Building
### a. Prerequisites to MSVC Build
* Open the CMake GUI application and point it to the `eden` (Master)
* **[Visual Studio 2022 Community](https://visualstudio.microsoft.com/downloads/)** - Make sure to **select C++ support** in the installer, or **update to the latest version** if already installed.

* *A convenience script to install the **minimal** version (Visual Build Tools) is provided in `.ci/windows/install-msvc.ps1`*
* For the build directory, use a `/build` subdirectory inside the source directory or some other directory of your choice. (Tell CMake to create it.)
---
* Click the "Configure" button and choose `Visual Studio 17 2022`, with `x64` for the optional platform.
### b. Clone the eden repository with Git
Open Terminal on
```cmd
git clone https://git.eden-emu.dev/eden-emu/eden
cd eden
```
* *By default `eden` downloads to `C:\Users\<user-name>\eden`*
---
### c. Building
* Open the CMake GUI application and point it to the `eden`
* * Depending on whether you want a graphical user interface or not, select in the Solution Explorer:
* `eden` (GUI)
* `eden-cmd` (command-line only)
* Then **right-click** and choose `Set as StartUp Project`.
* Depending if you want a graphical user interface or not (`eden` has the graphical user interface, while `eden-cmd` doesn't), select `eden` or `eden-cmd` in the Solution Explorer, right-click and `Set as StartUp Project`.
* [Vulkan SDK](https://vulkan.lunarg.com/sdk/home#windows) - **Make sure to select Latest SDK.**
* Make sure to follow the instructions and update to the latest version by running `pacman -Syu` as many times as needed.
* **[MSYS2](https://www.msys2.org)** - A versatile and up-to-date development environment for Windows, providing a Unix-like shell, package manager, and toolchain.
### Install eden dependencies for MinGW-w64
---
* Open the `MSYS2 MinGW 64-bit` (mingw64.exe) shell
* Download and install all dependencies using: `pacman -Syu git make mingw-w64-x86_64-SDL2 mingw-w64-x86_64-cmake mingw-w64-x86_64-python-pip mingw-w64-x86_64-qt6 mingw-w64-x86_64-toolchain autoconf libtool automake-wrapper`
* Add MinGW binaries to the PATH: `echo 'PATH=/mingw64/bin:$PATH' >> ~/.bashrc`
* Add glslangValidator to the PATH: `echo 'PATH=$(readlink -e /c/VulkanSDK/*/Bin/):$PATH' >> ~/.bashrc`
### b. Install eden dependencies for MinGW-w64
### Clone the eden repository with Git
* Open the `MSYS2 MinGW 64-bit` shell (`mingw64.exe`)
### Run the following commands to build eden (dynamically linked build)
### c. Clone the eden repository with Git
```cmd
git clone https://git.eden-emu.dev/eden-emu/eden
cd eden
```
---
### d. Building dynamically-linked eden
* This process will generate a *dynamically* linked build
```bash
# Make build dir and enter
mkdir build && cd build
cmake -G "MSYS Makefiles" -DYUZU_TESTS=OFF ..
# Generate CMake Makefiles
cmake .. -G "MSYS Makefiles" -DYUZU_TESTS=OFF
# Build
make -j$(nproc)
# test eden out with
# Run eden!
./bin/eden.exe
```
* *(Note: This build is not a static build meaning that you need to include all of the DLLs with the .exe in order to use it!)*
* *Warning: This build is not a **static** build meaning that you **need** to include all of the DLLs with the .exe in order to use it or other systems!*
e.g.
```Bash
cp externals/ffmpeg-*/bin/*.dll bin/
```
---
Bonus Note: Running programs from inside `MSYS2 MinGW x64` shell has a different %PATH% than directly from explorer. This different %PATH% has the locations of the other DLLs required.
cmake .. -G "Visual Studio 17 2022" -A x64 -DYUZU_TESTS=OFF
# Build
cmake --build . --config Release
```
### Building with Scripts
A convenience script for building is provided in `.ci/windows/build.sh`. You must run this with Bash, e.g. Git Bash or MinGW TTY. To use this script, you must have windeployqt installed (usually bundled with Qt) and set the `WINDEPLOYQT` environment variable to its canonical Bash location, e.g. `WINDEPLOYQT="/c/Qt/6.9.1/msvc2022_64/bin/windeployqt6.exe" .ci/windows/build.sh`.

* Note that using system Qt requires you to include the Qt CMake directory in `CMAKE_PREFIX_PATH`, e.g. `.ci/windows/build.sh -DCMAKE_PREFIX_PATH=C:/Qt/6.9.0/msvc2022_64/lib/cmake/Qt6`
* After building, a zip can be packaged via `.ci/windows/package.sh`. You must have 7-zip installed and in your PATH.
* The resulting zip will be placed into `artifacts` in the source directory.
