In addition to what is described here: - - In addition to minetest, you need to download minetest_game. - - If you wish to have sound support, you need libogg, libvorbis and libopenal - -- You need: - * CMake: - http://www.cmake.org/cmake/resources/software.html - * MinGW or Visual Studio - http://www.mingw.org/ - http://msdn.microsoft.com/en-us/vstudio/default - * Irrlicht SDK 1.7: - http://irrlicht.sourceforge.net/downloads.html - * Zlib headers (zlib125.zip) - http://www.winimage.com/zLibDll/index.html - * Zlib library (zlibwapi.lib and zlibwapi.dll from zlib125dll.zip): - http://www.winimage.com/zLibDll/index.html - * SQLite3 headers and library - https://www.sqlite.org/download.html - * Optional: gettext library and tools: - http://gnuwin32.sourceforge.net/downlinks/gettext.php - - This is used for other UI languages. Feel free to leave it out. - * And, of course, Minetest: - http://minetest.net/download -- Steps: - - Select a directory called DIR hereafter in which you will operate. - - Make sure you have CMake and a compiler installed. - - Download all the other stuff to DIR and extract them into there. - ("extract here", not "extract to packagename/") - NOTE: zlib125dll.zip needs to be extracted into zlib125dll - NOTE: You need to extract sqlite3.h & sqlite3ext.h from sqlite3 source - and sqlite3.dll & sqlite3.def from sqlite3 precompiled binaries - into "sqlite3" directory, and generate sqlite3.lib using command - "LIB /DEF:sqlite3.def /OUT:sqlite3.lib" - - All those packages contain a nice base directory in them, which - should end up being the direct subdirectories of DIR. - - You will end up with a directory structure like this (+=dir, -=file): - ----------------- - + DIR - - zlib-1.2.5.tar.gz - - zlib125dll.zip - - irrlicht-1.8.3.zip - - sqlite-amalgamation-3130000.zip (SQLite3 headers) - - sqlite-dll-win32-x86-3130000.zip (SQLite3 library for 32bit system) - - 110214175330.zip (or whatever, this is the minetest source) - + zlib-1.2.5 - - zlib.h - + win32 - ... - + zlib125dll - - readme.txt - + dll32 - ... - + irrlicht-1.8.3 - + lib - + include - ... - + sqlite3 - sqlite3.h - sqlite3ext.h - sqlite3.lib - sqlite3.dll - + gettext (optional) - +bin - +include - +lib - + minetest - + src - + doc - - CMakeLists.txt - ... - ----------------- - - Start up the CMake GUI - - Select "Browse Source..." and select DIR/minetest - - Now, if using MSVC: - - Select "Browse Build..." and select DIR/minetest-build - - Else if using MinGW: - - Select "Browse Build..." and select DIR/minetest - - Select "Configure" - - Select your compiler - - It will warn about missing stuff, ignore that at this point.

Make very sure to - select "Release", unless you want to debug some stuff (it's slower - and might not even work at all) - - Build the ALL_BUILD project - - Build the INSTALL project - - You should now have a working game with the executable in - DIR/minetest-install/bin/minetest.exe - - Additionally you may create a zip package by building the PACKAGE - project. - If using MinGW: - - Using the command line, browse to the build directory and run 'make' - (or mingw32-make or whatever it happens to be) - - You may need to copy some of the downloaded DLLs into bin/, see what - running the produced executable tells you it doesn't have. - - You should now have a working game with the executable in - DIR/minetest/bin/minetest.exe - -Windows releases of minetest are built using a bat script like this: --------------------------------------------------------------------- - -set sourcedir=%CD% -set installpath="C:\tmp\minetest_install" -set irrlichtpath="C:\tmp\irrlicht-1.7.2" - -set builddir=%sourcedir%\bvc10 -mkdir %builddir% -pushd %builddir% -cmake %sourcedir% -G "Visual Studio 10" -DIRRLICHT_SOURCE_DIR=%irrlichtpath% -DRUN_IN_PLACE=TRUE -DCMAKE_INSTALL_PREFIX=%installpath% -if %errorlevel% neq 0 goto fail -"C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe" ALL_BUILD.vcxproj /p:Configuration=Release -if %errorlevel% neq 0 goto fail -"C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe" INSTALL.vcxproj /p:Configuration=Release -if %errorlevel% neq 0 goto fail -"C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe" PACKAGE.vcxproj /p:Configuration=Release -if %errorlevel% neq 0 goto fail -popd -echo Finished. -exit /b 0 - -:fail -popd -echo Failed. -exit /b 1 - -License of Minetest textures and sounds ---------------------------------------- - -This applies to textures and sounds contained in the main Minetest -distribution. - -Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0) -http://creativecommons.org/licenses/by-sa/3.0/ - -Authors of media files ------------------------ -Everything not listed in here: -Copyright (C) 2010-2012 celeron55, Perttu Ahola - -ShadowNinja: - textures/base/pack/smoke_puff.png - -Paramat: - textures/base/pack/menu_header.png - -erlehmann: - misc/minetest-icon-24x24.png - misc/minetest-icon.ico - misc/minetest.svg - textures/base/pack/logo.png - -License of Minetest source code -------------------------------- - -Minetest -Copyright (C) 2010-2017 celeron55, Perttu Ahola - -This program is free software; you can redistribute it and/or modify -it under the terms of the GNU Lesser General Public License as published by -the Free Software Foundation; either version 2.1 of the License, or -(at your option) any later version. - -This program is distributed in the hope that it will be useful, -but WITHOUT ANY WARRANTY; without even the implied warranty of -MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
