Compiling DFHack

DFHack builds are available for all supported platforms; see Installing DFHack for installation instructions. If you are a DFHack end-user, modder, or plan on writing scripts (not plugins), it is generally recommended (and easier) to use these builds instead of compiling DFHack from source.

However, if you are looking to develop plugins, work on the DFHack core, make complex changes to DF-structures, or anything else that requires compiling DFHack from source, this document will walk you through the build process. Note that some steps may be unconventional compared to other projects, so be sure to pay close attention if this is your first time compiling DFHack.

How to get the code

DFHack uses Git for source control; instructions for installing Git can be found in the platform-specific sections below. The code is hosted on GitHub, and can be downloaded with:

git clone --recursive
cd dfhack

If your version of Git does not support the --recursive flag, you will need to omit it and run git submodule update --init after entering the dfhack directory.

This will check out the code on the default branch of the GitHub repo, currently develop, which may be unstable. If you want code for the latest stable release, you can check out the master branch instead:

git checkout master
git submodule update

In general, a single DFHack clone is suitable for development - most Git operations such as switching branches can be done on an existing clone. If you find yourself cloning DFHack frequently as part of your development process, or getting stuck on anything else Git-related, feel free to reach out to us for assistance.

A note on submodules

DFHack uses submodules extensively to manage its subprojects (including the scripts folder and DF-structures in library/xml). Failing to keep submodules in sync when switching between branches can result in build errors or scripts that don’t work. In general, you should always update submodules whenever you switch between branches in the main DFHack repo with git submodule update. (If you are working on bleeding-edge DFHack and have checked out the master branch of some submodules, running git pull in those submodules is also an option.)

Rarely, we add or remove submodules. If there are any changes to the existence of submodules when you switch between branches, you should run git submodule update --init instead (adding --init to the above command).

Some common errors that can arise when failing to update submodules include:

  • fatal: <some path> does not exist when performing Git operations
  • Build errors, particularly referring to structures in the df:: namespace or the library/include/df folder
  • Not a known DF version when starting DF
  • Run 'git submodule update --init' when running CMake

Submodules are a particularly confusing feature of Git. The Git Book has a thorough explanation of them (as well as of many other aspects of Git) and is a recommended resource if you run into any issues. Other DFHack developers are also able to help with any submodule-related (or Git-related) issues you may encounter.

Contributing to DFHack

To contribute to DFHack on GitHub, you will need a GitHub account. Only some DFHack developers can push directly to the DFHack repositories; we recommend making a fork of whatever repos you are interested in contributing to, making changes there, and submitting pull requests. GitHub’s pull request tutorial is a good resource for getting started with pull requests (some things to note: our work mainly happens on the develop branch, and you will need to use your own fork, assuming that you don’t have write access to the DFHack repos).

Most development-related discussion happens on IRC or in individual GitHub issues and pull requests, but there are also other ways to reach out - see Troubleshooting for details.

For more details on contributing to DFHack, including pull requests, code format, and more, please see Contributing Code.

Build settings

This section describes build configuration options that apply to all platforms. If you don’t have a working build environment set up yet, follow the instructions in the platform-specific sections below first, then come back here.


The Ninja CMake build generator is the preferred build method on Linux and macOS, instead of Unix Makefiles, which is the default. You can select Ninja by passing -G Ninja to CMake. Incremental builds using Unix Makefiles can be much slower than Ninja builds. Note that you will probably need to install Ninja; see the platform-specific sections for details.

cmake .. -G Ninja


Most other CMake settings can be changed by running cmake again, but the generator cannot be changed after cmake has been run without creating a new build folder. Do not forget to specify this option.

CMake versions 3.6 and older, and possibly as recent as 3.9, are known to produce project files with dependency cycles that fail to build (see Issue 1369). Obtaining a recent version of CMake is recommended, either from or through a package manager. See the sections below for more platform-specific directions for installing CMake.

Build type

cmake allows you to pick a build type by changing the CMAKE_BUILD_TYPE variable:


Valid and useful build types include ‘Release’ and ‘RelWithDebInfo’. The default build type is ‘Release’.

Target architecture (32-bit vs. 64-bit)

Set DFHACK_BUILD_ARCH to either 32 or 64 to build a 32-bit or 64-bit version of DFHack (respectively). The default is currently 64, so you will need to specify this explicitly for 32-bit builds. Specifying it is a good idea in any case.




Note that the scripts in the “build” folder on Windows will set the architecture automatically.

Other settings

There are a variety of other settings which you can find in CMakeCache.txt in your build folder or by running ccmake (or another CMake GUI). Most DFHack-specific settings begin with BUILD_ and control which parts of DFHack are built.


On Linux, DFHack acts as a library that shadows parts of the SDL API using LD_PRELOAD.


DFHack is meant to be installed into an existing DF folder, so get one ready.

We assume that any Linux platform will have git available (though it may need to be installed with your package manager.)

To build DFHack, you need GCC 4.8 or newer. GCC 4.8 has the benefit of avoiding libstdc++ compatibility issues, but can be hard to obtain on modern distributions, and working around these issues is done automatically by the dfhack launcher script. As long as your system-provided GCC is new enough, it should work. Note that extremely new GCC versions may not have been used to build DFHack yet, so if you run into issues with these, please let us know (e.g. by opening a GitHub issue).

Before you can build anything, you’ll also need cmake. It is advisable to also get ccmake on distributions that split the cmake package into multiple parts. As mentioned above, ninja is recommended (many distributions call this package ninja-build).

You will need pthread; most systems should have this already. Note that older CMake versions may have trouble detecting pthread, so if you run into pthread-related errors and pthread is installed, you may need to upgrade CMake, either by downloading it from or through your package manager, if possible.

You also need zlib, libsdl (1.2, not sdl2, like DF), perl, and the XML::LibXML and XML::LibXSLT perl packages (for the code generation parts). You should be able to find them in your distro repositories.

To build Stonesense, you’ll also need OpenGL headers.

Here are some package install commands for various platforms:

  • On Arch linux:

    • For the required Perl modules: perl-xml-libxml and perl-xml-libxslt (or through cpan)
  • On Ubuntu:

    apt-get install gcc cmake ninja-build git zlib1g-dev libsdl1.2-dev libxml-libxml-perl libxml-libxslt-perl
  • On Fedora:

    yum install gcc-c++ cmake ninja-build git zlib-devel SDL-devel perl-core perl-XML-LibXML perl-XML-LibXSLT ruby
  • Debian and derived distros should have similar requirements to Ubuntu.

Multilib dependencies

If you want to compile 32-bit DFHack on 64-bit distributions, you’ll need the multilib development tools and libraries:

  • gcc-multilib and g++-multilib
  • If you have installed a non-default version of GCC - for example, GCC 4.8 on a distribution that defaults to 5.x - you may need to add the version number to the multilib packages.
    • For example, gcc-4.8-multilib and g++-4.8-multilib if installing for GCC 4.8 on a system that uses a later GCC version.
    • This is definitely required on Ubuntu/Debian, check if using a different distribution.
  • zlib1g-dev:i386 (or a similar i386 zlib-dev package)

Note that installing a 32-bit GCC on 64-bit systems (e.g. gcc:i386 on Debian) will typically not work, as it depends on several other 32-bit libraries that conflict with system libraries. Alternatively, you might be able to use lxc to create a virtual 32-bit environment.


Building is fairly straightforward. Enter the build folder (or create an empty folder in the DFHack directory to use instead) and start the build like this:

cd build
cmake .. -G Ninja -DCMAKE_BUILD_TYPE:string=Release -DCMAKE_INSTALL_PREFIX=<path to DF>
ninja install  # or ninja -jX install to specify the number of cores (X) to use

<path to DF> should be a path to a copy of Dwarf Fortress, of the appropriate version for the DFHack you are building. This will build the library along with the normal set of plugins and install them into your DF folder.

Alternatively, you can use ccmake instead of cmake:

cd build
ccmake .. -G Ninja
ninja install

This will show a curses-based interface that lets you set all of the extra options. You can also use a cmake-friendly IDE like KDevelop 4 or the cmake-gui program.

Incompatible libstdc++

When compiling DFHack yourself, it builds against your system libstdc++. When Dwarf Fortress runs, it uses a libstdc++ shipped in the libs folder, which comes from GCC 4.8 and is incompatible with code compiled with newer GCC versions. As of DFHack 0.42.05-alpha1, the dfhack launcher script attempts to fix this by automatically removing the DF-provided libstdc++ on startup. In rare cases, this may fail and cause errors such as:

./libs/Dwarf_Fortress: /pathToDF/libs/ version
    `GLIBCXX_3.4.18' not found (required by ./hack/

The easiest way to fix this is generally removing the libstdc++ shipped with DF, which causes DF to use your system libstdc++ instead:

cd /path/to/DF/
rm libs/

Note that distributing binaries compiled with newer GCC versions may result in the opposite compatibily issue: users with older GCC versions may encounter similar errors. This is why DFHack distributes both GCC 4.8 and GCC 7 builds. If you are planning on distributing binaries to other users, we recommend using an older GCC (but still at least 4.8) version if possible.


DFHack functions similarly on macOS and Linux, and the majority of the information above regarding the build process (CMake and Ninja) applies here as well.

DFHack can officially be built on macOS only with GCC 4.8 or 7. Anything newer than 7 will require you to perform extra steps to get DFHack to run (see Notes for GCC 8+ or OS X 10.10+ users), and your build will likely not be redistributable.

Notes for GCC 8+ or OS X 10.10+ users

If none of these situations apply to you, skip to Dependencies and system set-up.

If you have issues building on OS X 10.10 (Yosemite) or above, try definining the following environment variable:


If you build with a GCC version newer than 7, DFHack will probably crash immediately on startup, or soon after. To fix this, you will need to replace hack/libstdc++.6.dylib with a symlink to the libstdc++.6.dylib included in your version of GCC:

cd <path to df>/hack && mv libstdc++.6.dylib libstdc++.6.dylib.orig &&
ln -s [PATH_TO_LIBSTDC++] .

For example, with GCC 6.3.0, PATH_TO_LIBSTDC++ would be:

/usr/local/Cellar/gcc@6/6.3.0/lib/gcc/6/libstdc++.6.dylib  # for 64-bit DFHack
/usr/local/Cellar/gcc@6/6.3.0/lib/gcc/6/i386/libstdc++.6.dylib  # for 32-bit DFHack

Note: If you build with a version of GCC that requires this, your DFHack build will not be redistributable. (Even if you copy the libstdc++.6.dylib from your GCC version and distribute that too, it will fail on older OS X versions.) For this reason, if you plan on distributing DFHack, it is highly recommended to use GCC 4.8 or 7.

Dependencies and system set-up

  1. Download and unpack a copy of the latest DF

  2. Install Xcode from the Mac App Store

  3. Install the XCode Command Line Tools by running the following command:

    xcode-select --install
  4. Install dependencies

    It is recommended to use Homebrew instead of MacPorts, as it is generally cleaner, quicker, and smarter. For example, installing MacPort’s GCC will install more than twice as many dependencies as Homebrew’s will, and all in both 32-bit and 64-bit variants. Homebrew also doesn’t require constant use of sudo.

    Using Homebrew (recommended):

    brew tap homebrew/versions
    brew install git
    brew install cmake
    brew install ninja
    brew install gcc@7

    Using MacPorts:

    sudo port install gcc7 +universal cmake +universal git-core +universal ninja +universal

    Macports will take some time - maybe hours. At some point it may ask you to install a Java environment; let it do so.

  5. Install Perl dependencies

  • Using system Perl

    • sudo cpan

      If this is the first time you’ve run cpan, you will need to go through the setup process. Just stick with the defaults for everything and you’ll be fine.

      If you are running OS X 10.6 (Snow Leopard) or earlier, good luck! You’ll need to open a separate Terminal window and run:

      sudo ln -s /usr/include/libxml2/libxml /usr/include/libxml
    • install XML::LibXML

    • install XML::LibXSLT

  • In a separate, local Perl install

    Rather than using system Perl, you might also want to consider the Perl manager, Perlbrew.

    This manages Perl 5 locally under ~/perl5/, providing an easy way to install Perl and run CPAN against it without sudo. It can maintain multiple Perl installs and being local has the benefit of easy migration and insulation from OS issues and upgrades.

    See for more details.


  • Get the DFHack source as per section How to get the code, above.

  • Set environment variables

    Homebrew (if installed elsewhere, replace /usr/local with $(brew --prefix)):

    export CC=/usr/local/bin/gcc-7
    export CXX=/usr/local/bin/g++-7


    export CC=/opt/local/bin/gcc-mp-7
    export CXX=/opt/local/bin/g++-mp-7

    Change the version numbers appropriately if you installed a different version of GCC.

    If you are confident that you have GCC in your path, you can omit the absolute paths:

    export CC=gcc-7
    export CXX=g++-7

    (adjust as needed for different GCC installations)

  • Build DFHack:

    mkdir build-osx
    cd build-osx
    cmake .. -G Ninja -DCMAKE_BUILD_TYPE:string=Release -DCMAKE_INSTALL_PREFIX=<path to DF>
    ninja install  # or ninja -jX install to specify the number of cores (X) to use

    <path to DF> should be a path to a copy of Dwarf Fortress, of the appropriate version for the DFHack you are building.


On Windows, DFHack replaces the SDL library distributed with DF.


You will need the following:

  • Microsoft Visual C++ 2015 or 2017
  • Git
  • CMake
  • Perl with XML::LibXML and XML::LibXSLT
    • It is recommended to install StrawberryPerl, which includes both.
  • Python (for documentation; optional, except for release builds)

Microsoft Visual Studio 2015

DFHack has to be compiled with the Microsoft Visual C++ 2015 or 2017 toolchain on Windows; other versions won’t work against Dwarf Fortress due to ABI and STL incompatibilities.

You can install Visual Studio 2015 or 2017 Community edition for free, which include all the features needed by DFHack. You can also download just the build tools if you aren’t going to use Visual Studio to edit code.

Additional dependencies: installing with the Chocolatey Package Manager

The remainder of dependencies - Git, CMake, StrawberryPerl, and Python - can be most easily installed using the Chocolatey Package Manger. Chocolatey is a *nix-style package manager for Windows. It’s fast, small (8-20MB on disk) and very capable. Think “apt-get for Windows.”

Chocolatey is a recommended way of installing the required dependencies as it’s quicker, requires less effort, and will install known-good utilities guaranteed to have the correct setup (especially PATH).

To install Chocolatey and the required dependencies:

  • Go to in a web browser

  • At the top of the page it will give you the install command to copy

    • Copy the first one, which starts @powershell ...
    • It won’t be repeated here in case it changes in future Chocolatey releases.
  • Open an elevated (Admin) cmd.exe window

    • On Windows 8 and later this can be easily achieved by:
      • right-clicking on the Start Menu, or pressing Win+X.
      • choosing “Command Prompt (Admin)”
    • On earlier Windows: find cmd.exe in Start Menu, right click and choose Open As Administrator.
  • Paste in the Chocolatey install command and hit enter

  • Close this cmd.exe window and open another Admin cmd.exe in the same way

  • Run the following command:

    choco install git cmake.portable strawberryperl -y
  • Close the Admin cmd.exe window; you’re done!

You can now use all of these utilities from any normal cmd.exe window. You only need Admin/elevated cmd.exe for running choco install commands; for all other purposes, including compiling DFHack, you should use a normal cmd.exe (or, better, an improved terminal like Cmder; details below, under Build.)

NOTE: you can run the above choco install command even if you already have Git, CMake or StrawberryPerl installed. Chocolatey will inform you if any software is already installed and won’t re-install it. In that case, please check the PATHs are correct for that utility as listed in the manual instructions below. Or, better, manually uninstall the version you have already and re-install via Chocolatey, which will ensure the PATH are set up right and will allow Chocolatey to manage that program for you in future.

Additional dependencies: installing manually

If you prefer to install manually rather than using Chocolatey, details and requirements are as below. If you do install manually, please ensure you have all PATHs set up correctly.


Some examples:


You can get the win32 installer version from the official site. It has the usual installer wizard. Make sure you let it add its binary folder to your binary search PATH so the tool can be later run from anywhere.

Perl / Strawberry Perl

For the code generation stage of the build process, you’ll need Perl 5 with XML::LibXML and XML::LibXSLT. Strawberry Perl is recommended as it includes all of the required packages in a single, easy install.

After install, ensure Perl is in your user’s PATH. This can be edited from Control Panel -> System -> Advanced System Settings -> Environment Variables.

The following directories must be in your PATH, in this order:

  • <path to perl>\c\bin
  • <path to perl>\perl\site\bin
  • <path to perl>\perl\bin
  • <path to perl>\perl\vendor\lib\auto\XML\LibXML (may only be required on some systems)

Be sure to close and re-open any existing cmd.exe windows after updating your PATH.

If you already have a different version of Perl installed (for example, from Cygwin), you can run into some trouble. Either remove the other Perl install from PATH, or install XML::LibXML and XML::LibXSLT for it using CPAN.


There are several different batch files in the win32 and win64 subfolders in the build folder, along with a script that’s used for picking the DF path. Use the subfolder corresponding to the architecture that you want to build for.

First, run set_df_path.vbs and point the dialog that pops up at a suitable DF installation which is of the appropriate version for the DFHack you are compiling. The result is the creation of the file DF_PATH.txt in the build directory. It contains the full path to the destination directory. You could therefore also create this file manually - or copy in a pre-prepared version - if you prefer.

Next, run one of the scripts with generate prefix. These create the MSVC solution file(s):

  • all will create a solution with everything enabled (and the kitchen sink).
  • gui will pop up the CMake GUI and let you choose what to build. This is probably what you want most of the time. Set the options you are interested in, then hit configure, then generate. More options can appear after the configure step.
  • minimal will create a minimal solution with just the bare necessities - the main library and standard plugins.
  • release will create a solution with everything that should be included in release builds of DFHack. Note that this includes documentation, which requires Python.

Then you can either open the solution with MSVC or use one of the msbuild scripts:

Building/installing from the command line:

In the build directory you will find several .bat files:

  • Scripts with build prefix will only build DFHack.
  • Scripts with install prefix will build DFHack and install it to the previously selected DF path.
  • Scripts with package prefix will build and create a .zip package of DFHack.

Compiling from the command line is generally the quickest and easiest option. However be aware that due to the limitations of cmd.exe - especially in versions of Windows prior to Windows 10 - it can be very hard to see what happens during a build. If you get a failure, you may miss important errors or warnings due to the tiny window size and extremely limited scrollback. For that reason you may prefer to compile in the IDE which will always show all build output.

Alternatively (or additionally), consider installing an improved Windows terminal such as Cmder. Easily installed through Chocolatey with: choco install cmder -y.

Note for Cygwin/msysgit users: It is also possible to compile DFHack from a Bash command line. This has three potential benefits:

  • When you’ve installed Git and are using its Bash, but haven’t added Git to your path:
    • You can load Git’s Bash and as long as it can access Perl and CMake, you can use it for compile without adding Git to your system path.
  • When you’ve installed Cygwin and its SSH server:
    • You can now SSH in to your Windows install and compile from a remote terminal; very useful if your Windows installation is a local VM on a *nix host OS.
  • In general: you can use Bash as your compilation terminal, meaning you have a decent sized window, scrollback, etc.
    • Whether you’re accessing it locally as with Git’s Bash, or remotely through Cygwin’s SSH server, this is far superior to using cmd.exe.

You don’t need to do anything special to compile from Bash. As long as your PATHs are set up correctly, you can run the same generate- and build/install/package- bat files as detailed above.

Building/installing from the Visual Studio IDE:

After running the CMake generate script you will have a new folder called VC2015 or VC2015_32, depending on the architecture you specified. Open the file dfhack.sln inside that folder. If you have multiple versions of Visual Studio installed, make sure you open with Visual Studio 2015.

The first thing you must then do is change the build type. It defaults to Debug, but this cannot be used on Windows. Debug is not binary-compatible with DF. If you try to use a debug build with DF, you’ll only get crashes and for this reason the Windows “debug” scripts actually do RelWithDebInfo builds. After loading the Solution, change the Build Type to either Release or RelWithDebInfo.

Then build the INSTALL target listed under CMakePredefinedTargets.

Building the documentation

The steps above will not build DFHack’s documentation by default. If you are editing documentation, see DFHack Documentation System for details on how to build it.

Misc. Notes

Note on building DFHack offline

As of 0.43.05, DFHack downloads several files during the build process, depending on your target OS and architecture. If your build machine’s internet connection is unreliable, or nonexistent, you can download these files in advance.

First, you must locate the files you will need. These can be found in the dfhack-bin repo. Look for the most recent version number before or equal to the DF version which you are building for. For example, suppose “0.43.05” and “0.43.07” are listed. You should choose “0.43.05” if you are building for 0.43.05 or 0.43.06, and “0.43.07” if you are building for 0.43.07 or 0.43.08.

Then, download all of the files you need, and save them to <path to DFHack clone>/CMake/downloads/<any filename>. The destination filename you choose does not matter, as long as the files end up in the CMake/downloads folder. You need to download all of the files for the architecture(s) you are building for. For example, if you are building for 32-bit Linux and 64-bit Windows, download all files starting with linux32 and win64. GitHub should sort files alphabetically, so all the files you need should be next to each other.


  • Any files containing “allegro” in their filename are only necessary for building Stonesense. If you are not building Stonesense, you don’t have to download these, as they are larger than any other listed files.

It is recommended that you create a build folder and run CMake to verify that you have downloaded everything at this point, assuming your download machine has CMake installed. This involves running a “generate” batch script on Windows, or a command starting with cmake .. -G Ninja on Linux and macOS, following the instructions in the sections above. CMake should automatically locate files that you placed in CMake/downloads, and use them instead of attempting to download them.

Note on using very old git versions with pre-0.43.03 DFHack versions

If you are using git 1.8.0 or older, and cloned DFHack before commit 85a920d (around DFHack v0.43.03-alpha1), you may run into fatal git errors when updating submodules after switching branches. This is due to those versions of git being unable to handle our change from “scripts/3rdparty/name” submodules to a single “scripts” submodule. This may be fixable by renaming .git/modules/scripts to something else and re-running git submodule update --init on the branch with the single scripts submodule (and running it again when switching back to the one with multiple submodules, if necessary), but it is usually much simpler to upgrade your git version.
