# Compiling on Windows using MSVC
## Requirements
- [Visual Studio 2015 or newer](https://visualstudio.microsoft.com)
- [CMake](https://cmake.org/download/)
- [vcpkg](https://github.com/Microsoft/vcpkg)
- [Git](https://git-scm.com/downloads)
## Compiling and installing the dependencies
It is highly recommended to use vcpkg to manage dependencies, installed at a path without spaces in it for compatibility with the Luanti build configuration.
```
"C:\Program Filesvcpkg\vcpkg.exe" # bad, may have issues
"C:\vcpkg\vcpkg.exe" # good, no spaces means fewer problems
```
If spaces are present, you may see errors like:
```
libtool: error: 'Files/vcpkg/buildtrees/libiconv/x64-windows-dbg/lib/libcharset.la' is not a directory
```
After you successfully built vcpkg you can easily install the required libraries:
```powershell
vcpkg install zlib zstd curl[winssl] openal-soft libvorbis libogg libjpeg-turbo sqlite3 freetype luajit gmp jsoncpp gettext[tools] sdl2 --triplet x64-windows
```
This command takes about 10-30 minutes to complete, depending on your device.
- `curl` is highly recommended, as it's required to read the serverlist; `curl[winssl]` is required to use the content store.
- `openal-soft`, `libvorbis` and `libogg` are optional, but required to use sound.
- `luajit` is optional, it replaces the integrated Lua interpreter with a faster just-in-time interpreter.
- `gmp` and `jsoncpp` are optional, otherwise the bundled versions will be compiled
- `gettext` is optional, but required to use translations.
There are other optional libraries, but we don't test if they can build and link correctly.
Use `--triplet` to specify the target triplet, e.g. `x64-windows` or `x86-windows`.
## Compile Luanti
There are two ways to compile Luanti: CMake GUI and CLI
### a) CMake GUI
1. Start up the CMake GUI (Win > search "cmake-gui" > open)
2. Select **Browse Source...** and select `DIR/minetest` (this is where you've cloned the repo)
3. Select **Browse Build...** and select `DIR/minetest/build` (this is a new folder that CMake will prompt to create)
4. Select **Configure**
5. Choose the right Visual Studio version and target platform. Currently, Luanti uses Visual Studio 16 2019, but newer VS versions should work as well. The VS version has to match the version of the installed dependencies.
6. Choose **Specify toolchain file for cross-compiling**
7. Click **Next**
8. Select the vcpkg toolchain file e.g. `D:/vcpkg/scripts/buildsystems/vcpkg.cmake`
9. Click Finish
10. Wait until CMake generates the cache file (this may take about 10-30 minutes, depending on your device)
11. If there are any errors, solve them and hit **Configure**
12. Click **Generate**
13. Click **Open Project**
14. Compile Luanti inside Visual Studio.
- If you get "Unable to start program '...\x64\Debug\ALL_BUILD'. Access is denied", try compiling via the CLI instead.
### b) CLI
Run the following script in PowerShell:
```powershell
cmake . -G"Visual Studio 16 2019" -DCMAKE_TOOLCHAIN_FILE=D:/vcpkg/scripts/buildsystems/vcpkg.cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_CURSES=OFF
cmake --build . --config Release
```
Make sure that the right compiler is selected and the path to the vcpkg toolchain is correct.
## Windows Installer using WiX Toolset
Requirements:
- [Visual Studio 2017](https://visualstudio.microsoft.com/)
- [WiX Toolset](https://wixtoolset.org/)
In the Visual Studio 2017 Installer select **Optional Features -> WiX Toolset**.
Build the binaries as described above, but make sure you unselect `RUN_IN_PLACE`.
Open the generated project file with Visual Studio. Right-click **Package** and choose **Generate**.
It may take some minutes to generate the installer.
