Paths
-----

Locations:

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

Where each location is on each platform:

* Windows .zip / RUN_IN_PLACE source:
    * bin   = bin
    * share = .
    * user  = .
* Linux installed:
    * bin   = /usr/bin
    * share = /usr/share/MultiCraft
    * user  = ~/.MultiCraft
* macOS:
    * bin   = Contents/MacOS
    * share = Contents/Resources
    * user  = Contents/User OR ~/Library/Application Support/MultiCraft

Worlds can be found as separate folders in: user/worlds/

Configuration file:
-------------------
- Default location:
    $user/MultiCraft.conf
- It is created by MultiCraft when it is ran the first time.
- A specific file can be specified on the command line:
    --config <path-to-file>
- A run-in-place build will look for the configuration file in
    $location_of_exe/../MultiCraft.conf and also $location_of_exe/../../MultiCraft.conf

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

### Compiling on GNU/Linux

#### Dependencies

| Dependency | Version | Commentary |
|------------|---------|------------|
| GCC        | 4.9+    | Can be replaced with Clang 3.4+ |
| CMake      | 2.6+    |            |
| Irrlicht   | 1.7.3+  |            |
| SQLite3    | 3.0+    |            |
| LuaJIT     | 2.0+    | Bundled Lua 5.1 is used if not present |
| GMP        | 5.0.0+  | Bundled mini-GMP is used if not present |
| JsonCPP    | 1.0.0+  | Bundled JsonCPP is used if not present |

For Debian/Ubuntu:

    $ sudo apt-get install build-essential libirrlicht-dev cmake libbz2-dev libpng-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-devel openal-soft-devel libvorbis-devel 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

#### Download

You can install git for easily keeping your copy up to date.
If you don’t 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

For Fedora users:

    $ sudo dnf install git

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/MultiCraft/MultiCraft.git
$ cd MultiCraft

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

#### Build

Build a version that runs directly from the source directory:

    $ cmake . -DRUN_IN_PLACE=TRUE
    $ make -j <number of processors>

Run it:

    $ ./bin/MultiCraft

- 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:
  * If you wish to have sound support, you need libogg, libvorbis and libopenal
  
* You need:
	* CMake:
		http://www.cmake.org/cmake/resources/software.html
	* A compiler
		* MinGW: http://www.mingw.org/
		* or Visual Studio: 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, MultiCraft:
		https://github.com/MultiCraftProject/MultiCraft
* 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)
		* MultiCraft-source.zip
		+ 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
		+ MultiCraft
			+ src
			+ doc
			* CMakeLists.txt
			...
	-----------------
	* Start up the CMake GUI
	* Select "Browse Source..." and select DIR/MultiCraft
	* Now, if using MSVC:
		* Select "Browse Build..." and select DIR/MultiCraft-build
	* Else if using MinGW:
		* Select "Browse Build..." and select DIR/MultiCraft
	* 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/MultiCraft-install
                IRRLICHT_SOURCE_DIR      DIR/irrlicht-1.8.3
                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_LIBRARIES        DIR/gettext/lib/intl.lib
                GETTEXT_MSGFMT           DIR/gettext/bin/msgfmt
	
	* If CMake complains it couldn't find SQLITE3, choose "Advanced" box on the
	  right top corner, then specify the location of SQLITE3_INCLUDE_DIR and
	  SQLITE3_LIBRARY manually.
	* If you want to build 64-bit MultiCraft, you will need to build 64-bit version
	  of irrlicht engine manually, as only 32-bit pre-built library is provided.
	* 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 MultiCraft.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/MultiCraft-install/bin/MultiCraft.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/MultiCraft/bin/MultiCraft.exe

### Bat script to build Windows releases of MultiCraft

This is how we build Windows releases.

    mkdir %builddir%
    pushd %builddir%
    cmake %sourcedir% -G "Visual Studio 10" -DIRRLICHT_SOURCE_DIR=%irrlichtpath% -DRUN_IN_PLACE=TRUE -DCMAKE_INSTALL_PREFIX=%installpath%
