Compiling DFHACK

Here's how you build dfhack!

Contents

Dependencies

Building on Linux

To run in the output folder (without installing) building the library is simple. Enter the build folder, run the tools. Like this:

cd build
cmake .. -DCMAKE_BUILD_TYPE:string=Release
make

This will build the library and its tools and place them in /output. You can also use a cmake-friendly IDE like KDevelop 4 or the cmake GUI program.

To be installed into the system or packaged:

cd build
cmake -DCMAKE_BUILD_TYPE:string=Release \
    -DCMAKE_INSTALL_PREFIX=/usr \
    -DMEMXML_DATA_PATH:path=/usr/share/dfhack ..
make
make install

With this dfhack installs:

See the section on the shared memory hook library (SHM).

Building on Windows

You need cmake. Get the win32 installer version from the official site: http://www.cmake.org/cmake/resources/software.html

It has the usual installer wizard thing.

Using mingw

You also need a compiler. I build dfhack using mingw. You can get it from the mingw site: http://www.mingw.org/

Get the automated installer, it will download newest version of mingw and set things up nicely.

You'll have to add C:\MinGW\ to your PATH variable.

Building

open up cmd and navigate to the dfhack\build folder, run cmake and the mingw version of make:

cd build
cmake .. -G"MinGW Makefiles" -DCMAKE_BUILD_TYPE:string=Release
mingw32-make

Using MSVC

open up cmd and navigate to the dfhack\build folder, run cmake:

cd build
cmake ..

This will generate MSVC solution and project files.

Note

You are working in the /build folder. Files added to projects will end up there! (and that's wrong). Any changes to the build system should be done by changing cmake configs and running cmake on them!

Also, you'll have to copy the Memory.xml file to the build output folders MSVC generates. For example from output/ to output/Release/

Using some other compiler

I'm afraid you are on your own. dfhack wasn't tested with any other compiler.

Try using a different cmake generator that's intended for your tools.

Build targets

dfhack has a few build targets:

Build types

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

cmake .. -DCMAKE_BUILD_TYPE:string=BUILD_TYPE

Without specifying a build type or 'None', cmake uses the CMAKE_CXX_FLAGS variable for building.

Valid an useful build types include 'Release', 'Debug' and 'RelWithDebInfo'. There are others, but they aren't really that useful.

Have fun.

Building the shared memory hook library (SHM)

Unlike the rest of DFHack, The SHM needs special treatment when it comes to compilation. Because it shares the memory space with DF itself, it has to be built with the same tools as DF and use the same C and C++/STL libraries.

For DF 31.01 - 31.10 on Windows, use MSVC 2008. You can get the Express edition for free from Microsoft.

Windows dependencies can be determined by a tool like depends.exe (google it). Both the fake SDL.dll and DF have to use the same version of the C runtime (MSVCRT). The SHM can only be debugged using a RelWithDebInfo build!

Linux dependencies can be determined by setting the LD_DEBUG variable and running ./df:

export LD_DEBUG=versions
./df

Example of (a part of a) relevant output from a working SHM installation:

libdfconnect is the SHM. Both are compiled against the same C++ library and share the same CXXABI version.

Precompiled SHM libraries are provided in binary releases.

Checking strings support

Strings are one of the important C++ types and a great indicator that the SHM works. Tools like Dwarf Therapist depend on string support. Reading of strings can be checked by running any of the tools that deal with materials.

String writing is best tested with a fresh throw-away fort and dfrenamer.

Embark, give one dwarf a very long name using dfrenamer and save/exit. If DF crashes during the save sequence, your SHM is not compatible with DF and the throw-away fort is most probably lost.
