161 #### Download
162
163 You can install Git for easily keeping your copy up to date.
164 If you don’t want Git, read below on how to get the source without Git.
165 This is an example for installing Git on Debian/Ubuntu:
166
167     sudo apt install git
168
169 For Fedora users:
170
171     sudo dnf install git
172
173 Download source (this is the URL to the latest of source repository, which might not work at all times) using Git:
174
175     git clone --depth 1 https://github.com/minetest/minetest.git
176     cd minetest
177
178 Download minetest_game (otherwise only the "Development Test" game is available) using Git:
179
180     git clone --depth 1 https://github.com/minetest/minetest_game.git games/minetest_game
181
182 Download IrrlichtMt to `lib/irrlichtmt`, it will be used to satisfy the IrrlichtMt dependency that way:
183
184     git clone --depth 1 https://github.com/minetest/irrlicht.git lib/irrlichtmt
185
186 Download source, without using Git:
187
188     wget https://github.com/minetest/minetest/archive/master.tar.gz
189     tar xf master.tar.gz
190     cd minetest-master
191
192 Download minetest_game, without using Git:
193
194     cd games/
195     wget https://github.com/minetest/minetest_game/archive/master.tar.gz
196     tar xf master.tar.gz
197     mv minetest_game-master minetest_game
198     cd ..
199
200 Download IrrlichtMt, without using Git:
201
202     cd lib/
203     wget https://github.com/minetest/irrlicht/archive/master.tar.gz
204     tar xf master.tar.gz
205     mv irrlicht-master irrlichtmt
206     cd ..
207
208 #### Build
209
210 Build a version that runs directly from the source directory:
211
212     cmake . -DRUN_IN_PLACE=TRUE
213     make -j$(nproc)
214
215 Run it:
216
217     ./bin/minetest
218
219 - Use `cmake . -LH` to see all CMake options and their current state.
220 - If you want to install it system-wide (or are making a distribution package),
221   you will want to use `-DRUN_IN_PLACE=FALSE`.
222 - You can build a bare server by specifying `-DBUILD_SERVER=TRUE`.
223 - You can disable the client build by specifying `-DBUILD_CLIENT=FALSE`.
224 - You can select between Release and Debug build by `-DCMAKE_BUILD_TYPE=<Debug or Release>`.
225   - Debug build is slower, but gives much more useful output in a debugger.
226 - If you build a bare server you don't need to have the Irrlicht or IrrlichtMt library installed.
227   - In that case use `-DIRRLICHT_INCLUDE_DIR=/some/where/irrlicht/include`.
228
229 - Minetest will use the IrrlichtMt package that is found first, given by the following order:
230   1. Specified `IRRLICHTMT_BUILD_DIR` CMake variable
231   2. `${PROJECT_SOURCE_DIR}/lib/irrlichtmt` (if existent)
232   3. Installation of IrrlichtMt in the system-specific library paths
233   4. For server builds with disabled `BUILD_CLIENT` variable, the headers from `IRRLICHT_INCLUDE_DIR` will be used.
234   - NOTE: Changing the IrrlichtMt build directory (includes system installs) requires regenerating the CMake cache (`rm CMakeCache.txt`)
235

319 ### Compiling on Windows using MSVC
320
321 ### Requirements
322
323 - [Visual Studio 2015 or newer](https://visualstudio.microsoft.com)
324 - [CMake](https://cmake.org/download/)
325 - [vcpkg](https://github.com/Microsoft/vcpkg)
326 - [Git](https://git-scm.com/downloads)
327
328 ### Compiling and installing the dependencies
329
330 It is highly recommended to use vcpkg as package manager.
331
332 After you successfully built vcpkg you can easily install the required libraries:
333 ```powershell
334 vcpkg install zlib zstd curl[winssl] openal-soft libvorbis libogg libjpeg-turbo sqlite3 freetype luajit gmp jsoncpp opengl-registry --triplet x64-windows
335 ```
336
337 - **Don't forget about IrrlichtMt.** The easiest way is to clone it to `lib/irrlichtmt` as described in the Linux section.
338 - `curl` is optional, but required to read the serverlist, `curl[winssl]` is required to use the content store.
339 - `openal-soft`, `libvorbis` and `libogg` are optional, but required to use sound.
340 - `luajit` is optional, it replaces the integrated Lua interpreter with a faster just-in-time interpreter.
341 - `gmp` and `jsoncpp` are optional, otherwise the bundled versions will be compiled
342
343 There are other optional libraries, but they are not tested if they can build and link correctly.
344
345 Use `--triplet` to specify the target triplet, e.g. `x64-windows` or `x86-windows`.
346
347 ### Compile Minetest
348
349 #### a) Using the vcpkg toolchain and CMake GUI
350 1. Start up the CMake GUI
351 2. Select **Browse Source...** and select DIR/minetest
352 3. Select **Browse Build...** and select DIR/minetest-build
353 4. Select **Configure**
354 5. Choose the right visual Studio version and target platform. It has to match the version of the installed dependencies
355 6. Choose **Specify toolchain file for cross-compiling**
356 7. Click **Next**
357 8. Select the vcpkg toolchain file e.g. `D:/vcpkg/scripts/buildsystems/vcpkg.cmake`
358 9. Click Finish
359 10. Wait until cmake have generated the cash file
360 11. If there are any errors, solve them and hit **Configure**
361 12. Click **Generate**
362 13. Click **Open Project**
363 14. Compile Minetest inside Visual studio.
364
365 #### b) Using the vcpkg toolchain and the commandline
366
367 Run the following script in PowerShell:
368
369 ```powershell
370 cmake . -G"Visual Studio 15 2017 Win64" -DCMAKE_TOOLCHAIN_FILE=D:/vcpkg/scripts/buildsystems/vcpkg.cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_GETTEXT=OFF -DENABLE_CURSES=OFF
371 cmake --build . --config Release
372 ```
373 Make sure that the right compiler is selected and the path to the vcpkg toolchain is correct.
374
375 ### Windows Installer using WiX Toolset
376
377 Requirements:
378 * [Visual Studio 2017](https://visualstudio.microsoft.com/)
379 * [WiX Toolset](https://wixtoolset.org/)
380
381 In the Visual Studio 2017 Installer select **Optional Features -> WiX Toolset**.
382
383 Build the binaries as described above, but make sure you unselect `RUN_IN_PLACE`.
384
385 Open the generated project file with Visual Studio. Right-click **Package** and choose **Generate**.
386 It may take some minutes to generate the installer.
387
388 ### Compiling on MacOS
389
390 #### Requirements

398 ```
399
400 #### Download
401
402 Download source (this is the URL to the latest of source repository, which might not work at all times) using Git:
403
404 ```bash
405 git clone --depth 1 https://github.com/minetest/minetest.git
406 cd minetest
407 ```
408
409 Download minetest_game (otherwise only the "Development Test" game is available) using Git:
410
411 ```
412 git clone --depth 1 https://github.com/minetest/minetest_game.git games/minetest_game
413 ```
414
415 Download Minetest's fork of Irrlicht:

434 make install
435 ```
436
437 #### Run
438
439 ```
440 open ./build/macos/minetest.app
441 ```
442
443 Docker
444 ------
445 We provide Minetest server Docker images using the GitLab mirror registry.
446
447 Images are built on each commit and available using the following tag scheme:
448
449 * `registry.gitlab.com/minetest/minetest/server:latest` (latest build)
450 * `registry.gitlab.com/minetest/minetest/server:<branch/tag>` (current branch or current tag)
451 * `registry.gitlab.com/minetest/minetest/server:<commit-id>` (current commit id)
452
453 If you want to test it on a Docker server you can easily run:
454
455         sudo docker run registry.gitlab.com/minetest/minetest/server:<docker tag>
456
457 If you want to use it in a production environment you should use volumes bound to the Docker host
458 to persist data and modify the configuration:
459
460         sudo docker create -v /home/minetest/data/:/var/lib/minetest/ -v /home/minetest/conf/:/etc/minetest/ registry.gitlab.com/minetest/minetest/server:master
461
462 Data will be written to `/home/minetest/data` on the host, and configuration will be read from `/home/minetest/conf/minetest.conf`.
463
464 **Note:** If you don't understand the previous commands please read the official Docker documentation before use.
465
466 You can also host your Minetest server inside a Kubernetes cluster. See our example implementation in [`misc/kubernetes.yml`](misc/kubernetes.yml).
467
468
469 Version scheme
470 --------------
471 We use `major.minor.patch` since 5.0.0-dev. Prior to that we used `0.major.minor`.
472
473 - Major is incremented when the release contains breaking changes, all other
474 numbers are set to 0.
475 - Minor is incremented when the release contains new non-breaking features,
476 patch is set to 0.
477 - Patch is incremented when the release only contains bugfixes and very
478 minor/trivial features considered necessary.
479
480 Since 5.0.0-dev and 0.4.17-dev, the dev notation refers to the next release,
481 i.e.: 5.0.0-dev is the development version leading to 5.0.0.
482 Prior to that we used `previous_version-dev`.
