 136
 137 #### Download
 138
 139 You can install Git for easily keeping your copy up to date.
 140 If you don’t want Git, read below on how to get the source without Git.
 141 This is an example for installing Git on Debian/Ubuntu:
 142
 143     sudo apt install git
 144
 145 For Fedora users:
 146
 147     sudo dnf install git
 148
 149 Download source (this is the URL to the latest of source repository, which might not work at all times) using Git:
 150
 151     git clone --depth 1 https://github.com/minetest/minetest.git
 152     cd minetest
 153
 154 Download minetest_game (otherwise only the "Minimal development test" game is available) using Git:
 155
 156     git clone --depth 1 https://github.com/minetest/minetest_game.git games/minetest_game
 157
 158 Download source, without using Git:
 159
 160     wget https://github.com/minetest/minetest/archive/master.tar.gz
 161     tar xf master.tar.gz
 162     cd minetest-master
 163
 164 Download minetest_game, without using Git:
 165
 166     cd games/
 167     wget https://github.com/minetest/minetest_game/archive/master.tar.gz
 168     tar xf master.tar.gz
 169     mv minetest_game-master minetest_game
 170     cd ..
 171
 172 #### Build
 173
 174 Build a version that runs directly from the source directory:
 175
 176     cmake . -DRUN_IN_PLACE=TRUE
 177     make -j <number of processors>
 178
 179 Run it:
 180
 181     ./bin/minetest
 182
 183 - Use `cmake . -LH` to see all CMake options and their current state
 184 - If you want to install it system-wide (or are making a distribution package),
 185   you will want to use `-DRUN_IN_PLACE=FALSE`
 186 - You can build a bare server by specifying `-DBUILD_SERVER=TRUE`
 187 - You can disable the client build by specifying `-DBUILD_CLIENT=FALSE`
 188 - You can select between Release and Debug build by `-DCMAKE_BUILD_TYPE=<Debug or Release>`
 189   - Debug build is slower, but gives much more useful output in a debugger
 190 - If you build a bare server, you don't need to have Irrlicht installed.
 191   - In that case use `-DIRRLICHT_SOURCE_DIR=/the/irrlicht/source`

 294                 http://www.winimage.com/zLibDll/index.html
 295         * SQLite3 headers and library
 296                 https://www.sqlite.org/download.html
 297         * Optional: gettext library and tools:
 298                 http://gnuwin32.sourceforge.net/downlinks/gettext.php
 299                 * This is used for other UI languages. Feel free to leave it out.
 300         * And, of course, Minetest:
 301                 http://minetest.net/download
 302 * Steps:
 303         * Select a directory called DIR hereafter in which you will operate.
 304         * Make sure you have CMake and a compiler installed.
 305         * Download all the other stuff to DIR and extract them into there.
 306           ("extract here", not "extract to packagename/")
 307             * NOTE: zlib125dll.zip needs to be extracted into zlib125dll
 308             * NOTE: You need to extract sqlite3.h & sqlite3ext.h from the SQLite 3
 309               source and sqlite3.dll & sqlite3.def from the SQLite 3 precompiled
 310               binaries into "sqlite3" directory, and generate sqlite3.lib using
 311               command "LIB /DEF:sqlite3.def /OUT:sqlite3.lib"
 312         * All those packages contain a nice base directory in them, which
 313           should end up being the direct subdirectories of DIR.
 314         * You will end up with a directory structure like this (+=dir, -=file):
 315         -----------------
 316         + DIR
 317                 * zlib-1.2.5.tar.gz
 318                 * zlib125dll.zip
 319                 * irrlicht-1.8.3.zip
 320                 * sqlite-amalgamation-3130000.zip (SQLite3 headers)
 321                 * sqlite-dll-win32-x86-3130000.zip (SQLite3 library for 32bit system)
 322                 * 110214175330.zip (or whatever, this is the minetest source)
 323                 + zlib-1.2.5
 324                         * zlib.h
 325                         + win32
 326                         ...
 327                 + zlib125dll
 328                         * readme.txt
 329                         + dll32
 330                         ...
 331                 + irrlicht-1.8.3
 332                         + lib
 333                         + include
 334                         ...
 335                 + sqlite3
 336                         sqlite3.h
 337                         sqlite3ext.h
 338                         sqlite3.lib
 339                         sqlite3.dll
 340                 + gettext (optional)
 341                         +bin
 342                         +include
 343                         +lib
 344                 + minetest
 345                         + src
 346                         + doc
 347                         * CMakeLists.txt
 348                         ...
 349         -----------------
 350         * Start up the CMake GUI
 351         * Select "Browse Source..." and select DIR/minetest
 352         * Now, if using MSVC:
 353                 * Select "Browse Build..." and select DIR/minetest-build
 354         * Else if using MinGW:
 355                 * Select "Browse Build..." and select DIR/minetest
 356         * Select "Configure"
 357         * Select your compiler
 358         * It will warn about missing stuff, ignore that at this point. (later don't)
 359         * Make sure the configuration is as follows
 360           (note that the versions may differ for you):
 361
 362                 BUILD_CLIENT             [X]
 363                 BUILD_SERVER             [ ]
 364                 CMAKE_BUILD_TYPE         Release
 365                 CMAKE_INSTALL_PREFIX     DIR/minetest-install
 366                 IRRLICHT_SOURCE_DIR      DIR/irrlicht-1.8.3
 367                 RUN_IN_PLACE             [X]
 368                 WARN_ALL                 [ ]
 369                 ZLIB_DLL                 DIR/zlib125dll/dll32/zlibwapi.dll
 370                 ZLIB_INCLUDE_DIR         DIR/zlib-1.2.5
 371                 ZLIB_LIBRARIES           DIR/zlib125dll/dll32/zlibwapi.lib
 372                 GETTEXT_BIN_DIR          DIR/gettext/bin
 373                 GETTEXT_INCLUDE_DIR      DIR/gettext/include
 374                 GETTEXT_LIBRARIES        DIR/gettext/lib/intl.lib
 375                 GETTEXT_MSGFMT           DIR/gettext/bin/msgfmt
 376
 377         * If CMake complains it couldn't find SQLITE3, choose "Advanced" box on the
 378           right top corner, then specify the location of SQLITE3_INCLUDE_DIR and
 379           SQLITE3_LIBRARY manually.
 380         * If you want to build 64-bit minetest, you will need to build 64-bit version
 381           of irrlicht engine manually, as only 32-bit pre-built library is provided.
 382         * Hit "Configure"
 383         * Hit "Configure" once again 8)
 384         * If something is still coloured red, you have a problem.
 385         * Hit "Generate"
 386         If using MSVC:
 387                 * Open the generated minetest.sln
 388                 * The project defaults to the "Debug" configuration. Make very sure to
 389                   select "Release", unless you want to debug some stuff (it's slower
 390                   and might not even work at all)
 391                 * Build the ALL_BUILD project
 392                 * Build the INSTALL project
 393                 * You should now have a working game with the executable in
 394                         DIR/minetest-install/bin/minetest.exe
 395                 * Additionally you may create a zip package by building the PACKAGE
 396                   project.
 397         If using MinGW:
 398                 * Using the command line, browse to the build directory and run 'make'
 399                   (or mingw32-make or whatever it happens to be)
 400                 * You may need to copy some of the downloaded DLLs into bin/, see what
 401                   running the produced executable tells you it doesn't have.
 402                 * You should now have a working game with the executable in
 403                         DIR/minetest/bin/minetest.exe

 405 ### Bat script to build Windows releases of Minetest
 406
 407 This is how we build Windows releases.
 408
 409     set sourcedir=%CD%
 410     set installpath="C:\tmp\minetest_install"
 411     set irrlichtpath="C:\tmp\irrlicht-1.7.2"
 412
 413     set builddir=%sourcedir%\bvc10
 414     mkdir %builddir%
 415     pushd %builddir%
 416     cmake %sourcedir% -G "Visual Studio 10" -DIRRLICHT_SOURCE_DIR=%irrlichtpath% -DRUN_IN_PLACE=TRUE -DCMAKE_INSTALL_PREFIX=%installpath%
 417     if %errorlevel% neq 0 goto fail
 418     "C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe" ALL_BUILD.vcxproj /p:Configuration=Release
 419     if %errorlevel% neq 0 goto fail
 420     "C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe" INSTALL.vcxproj /p:Configuration=Release
 421     if %errorlevel% neq 0 goto fail
 422     "C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe" PACKAGE.vcxproj /p:Configuration=Release
 423     if %errorlevel% neq 0 goto fail
 424     popd
 425     echo Finished.
 426     exit /b 0
 427
 428     :fail
 429     popd
 430     echo Failed.
 431     exit /b 1
 432
 433 ### Windows Installer using WIX Toolset
 434
 435 Requirements:
 436 * Visual Studio 2017
 437 * Wix Toolset
 438
 439 In Visual Studio 2017 Installer select "Optional Features" -> "Wix Toolset"
 440
 441 Build the binaries like described above, but make sure you unselect "RUN_IN_PLACE".
 442
 443 Open the generated Project file with VS. Right click "PACKAGE" and choose "Generate".
 444 It may take some minutes to generate the installer.
 445
 446 Version scheme
 447 --------------
 448 We use `major.minor.patch` since 5.0.0-dev. Prior to that we used `0.major.minor`.
 449
 450 - Major is incremented when the release contains breaking changes, all other
 451 numbers are set to 0.
 452 - Minor is incremented when the release contains new non-breaking features,
 453 patch is set to 0.
 454 - Patch is incremented when the release only contains bugfixes and very
 455 minor/trivial features considered necessary.
 456
 457 Since 5.0.0-dev and 0.4.17-dev, the dev notation refers to the next release,
 458 i.e.: 5.0.0-dev is the development version leading to 5.0.0.
 459 Prior to that we used `previous_version-dev`.
