If you downloaded the Minetest Engine source code in which this file is
contained, you probably want to download the minetest_game project too:

Paths
------
$bin   - Compiled binaries
$share - Distributed read-only data
$user  - User-created modifiable data

Windows .zip / RUN_IN_PLACE source:
$bin   = bin
$share = .
$user  = .

Linux installed:
$bin   = /usr/bin
$share = /usr/share/minetest
$user  = ~/.minetest

OS X:
$bin   = Contents/MacOS
$share = Contents/Resources
$user  = Contents/User OR ~/Library/Application Support/minetest

World directory
----------------
- Worlds can be found as separate folders in:
    $user/worlds/

Configuration file:
-------------------
- Default location:
    $user/minetest.conf
- It is created by Minetest when it is ran the first time.
- A specific file can be specified on the command line:
	--config <path-to-file>

Command-line options:
---------------------
- Use --help

Compiling on GNU/Linux:
-----------------------

Install dependencies. Here's an example for Debian/Ubuntu:
$ sudo apt-get install build-essential libirrlicht-dev cmake libbz2-dev libpng12-dev libjpeg-dev libxxf86vm-dev libgl1-mesa-dev libsqlite3-dev libogg-dev libvorbis-dev libopenal-dev libcurl4-gnutls-dev libfreetype6-dev zlib1g-dev libgmp-dev libjsoncpp-dev

For Fedora users:
$ sudo dnf install make automake gcc gcc-c++ kernel-devel cmake libcurl* openal* libvorbis* libXxf86vm-devel libogg-devel freetype-devel mesa-libGL-devel zlib-devel jsoncpp-devel irrlicht-devel bzip2-libs gmp-devel sqlite-devel luajit-devel leveldb-devel ncurses-devel doxygen spatialindex-devel bzip2-devel

You can install git for easily keeping your copy up to date.
If you dont want git, read below on how to get the source without git.
This is an example for installing git on Debian/Ubuntu:
$ sudo apt-get install git-core

For Fedora users:
$ sudo dnf install git-core

Download source (this is the URL to the latest of source repository, which might not work at all times) using git:
$ git clone --depth 1 https://github.com/minetest/minetest.git
$ cd minetest

Download minetest_game (otherwise only the "Minimal development test" game is available) using git:
$ git clone --depth 1 https://github.com/minetest/minetest_game.git games/minetest_game

Download source, without using git:
$ wget https://github.com/minetest/minetest/archive/master.tar.gz
$ tar xf master.tar.gz
$ cd minetest-master

Download minetest_game, without using git:
$ cd games/
$ wget https://github.com/minetest/minetest_game/archive/master.tar.gz
$ tar xf master.tar.gz
$ mv minetest_game-master minetest_game
$ cd ..

Build a version that runs directly from the source directory:
$ cmake . -DRUN_IN_PLACE=TRUE
$ make -j <number of processors>

Run it:
$ ./bin/minetest

- Use cmake . -LH to see all CMake options and their current state
- If you want to install it system-wide (or are making a distribution package),
  you will want to use -DRUN_IN_PLACE=FALSE
- You can build a bare server by specifying -DBUILD_SERVER=TRUE
- You can disable the client build by specifying -DBUILD_CLIENT=FALSE
- You can select between Release and Debug build by -DCMAKE_BUILD_TYPE=<Debug or Release>
  - Debug build is slower, but gives much more useful output in a debugger
- If you build a bare server, you don't need to have Irrlicht installed.
  In that case use -DIRRLICHT_SOURCE_DIR=/the/irrlicht/source

Compiling on Windows:
---------------------
- This section is outdated. 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
	* 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
	- 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-1.7.1.zip
		- 110214175330.zip (or whatever, this is the minetest source)
		+ zlib-1.2.5
			- zlib.h
			+ win32
			...
		+ zlib125dll
			- readme.txt
			+ dll32
			...
		+ irrlicht-1.7.1
			+ lib
			+ include
			...
		+ 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. (later don't)
	- Make sure the configuration is as follows
	  (note that the versions may differ for you):
	-----------------
	BUILD_CLIENT             [X]
	BUILD_SERVER             [ ]
	CMAKE_BUILD_TYPE         Release
	CMAKE_INSTALL_PREFIX     DIR/minetest-install
	IRRLICHT_SOURCE_DIR      DIR/irrlicht-1.7.1
	RUN_IN_PLACE             [X]
	WARN_ALL                 [ ]
	ZLIB_DLL                 DIR/zlib125dll/dll32/zlibwapi.dll
	ZLIB_INCLUDE_DIR         DIR/zlib-1.2.5
	ZLIB_LIBRARIES           DIR/zlib125dll/dll32/zlibwapi.lib
	GETTEXT_BIN_DIR          DIR/gettext/bin
	GETTEXT_INCLUDE_DIR      DIR/gettext/include
	GETTEXT_LIBRARIES        DIR/gettext/lib/intl.lib
	GETTEXT_MSGFMT           DIR/gettext/bin/msgfmt
	-----------------
	- Hit "Configure"
	- Hit "Configure" once again 8)
	- If something is still coloured red, you have a problem.
	- Hit "Generate"
	If using MSVC:
		- Open the generated minetest.sln
		- The project defaults to the "Debug" configuration. 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:
