Simutrans-Extended (formerly Simutrans-Experimental) is a fork of the popular open source transport simulation game, Simutrans. Your goal is to establish a successful transport company. Transport passengers, mail and goods by rail, road, ship, and even air. Interconnect districts, cities, public buildings, industries and tourist attractions by building a transport network you always dreamed of.

You can download Simutrans-Extended from:

• Bridgewater-Brunel Simutrans-Extended server
• Steam (opting in the "extended" beta branch)

Simutrans-Extended is updated nightly, so you will need an up-to-date game to play network games. For this purpose, an automatic updater is available (requires Java 9 or later). If you play Simutrans-Extended on Steam, the Steam client will take care of updates for you.

This is a short guide on compiling Simutrans-Extended. If you want more detailed information, read the Compiling Simutrans wiki page. Note: A system set up to compile Simutrans should be able to compile Simutrans-Extended.

If you are on Windows, download either Microsoft Visual Studio or MSYS2. MSVC is easy for debugging, MSYS2 is easy to set up (but it has to be done on the command line).

You can download the latest version with a git client:

git clone https://github.com/jamespetts/simutrans-extended.git

This is a list of libraries used by Simutrans-Extended. Not all of them are necessary, some are optional, so pick them according to your needs. Read below about how to install them.

You will also need pkgconfig (Unix) or vcpkg (MSVC CMake)

• MSVC CMake: Install libaries using vpkg ./vcpkg/vcpkg --triplet x64-windows-static install zlib bzip2 libpng zstd sdl2 freetype miniupnpc
• MSVC (alone): You will need to download libraries manually. Check How to compile Simutrans Extended with Visual Studio 2015 for more info.
• MSYS2: Run setup-mingw.sh to get the libraries and set up the environment.
• Linux: Use pkgs.org to search for development libraries available in your package manager.
• Mac: Install libraries via Homebrew.

Go to the source code directory of simutrans-extended. You have three build systems to choose from: make, MSVC, and CMake. We recommend make or MSVC for debug builds.

Compiling will give you only the executable, you still need a Simutrans-Extended installation to run the program. You can start simutrans-extended with -use_workdir to point it to an existing installation.

The executable will be built in build/default.

(Linux) autoconf
(MacOS) autoreconf -ivf
./configure
make -j 4
(MacOS) make OSX/getversion

Open Simutrans-Extended.sln, choose the configuration you want and compile.

The executable will be built in build/simutrans-extended.

mkdir build && cd build
cmake -G "Insert Correct Makefiles Generator" ..
cmake --build . -j 4

See here for a list of generators.

mkdir build && cd build
cmake.exe .. -G "Visual Studio 16 2019" -A x64 -DCMAKE_TOOLCHAIN_FILE=[vcpkg-root]/scripts/buildsystems/vcpkg.cmake
cmake --build . --config Release

If you want to cross-compile Simutrans-Extended from Linux for Windows, see the Cross-Compiling Simutrans wiki page.

Simutrans was originally written by Hansjörg Malthaner "Hajo" from 1997 until he retired from development around 2004. Since then a team of contributors (The Simutrans Team) lead by Markus Pristovsek "Prissi" develop Simutrans. The Simutrans-Extended development is lead by James E. Petts with help of many contributors.
