Compiling DFHACK Building DFHACK

Here's how you build dfhack!

Building on Linux
=================
On Linux, DFHack acts as a library that shadows parts of the SDL API using LD_PRELOAD.
Dependencies Dependencies
============ ============
* ``cmake`` DFHack is meant to be installed into an existing DF folder, so get one ready.
* A compiler for building the main lib and the various tools.
* (Linux only) Veinlook requires the wide-character ncurses library (libncursesw)
* (Linux only) You'll need X11 dev libraries.
Building on Linux For building, you need a 32-bit version of GCC. For example, to build DFHack on
================= a 64-bit distribution like Arch, you'll need the multilib development tools and libraries.
To run in the output folder (without installing) building the library
is simple. Enter the build folder, run the tools. Like this:: 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.
Build
=====
Building is fairly straightforward. Enter the ``build`` folder and start the build like this::
cd build cd build
cmake .. -DCMAKE_BUILD_TYPE:string=Release cmake .. -DCMAKE_BUILD_TYPE:string=Release -DCMAKE_INSTALL_PREFIX=/home/user/DF
make make install
This will build the library and its tools and place them in a sub-directory ``bin`` inside your build directory.
Alternatively, you can use ccmake instead of cmake: Obviously, replace the install path with path to your DF. 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 cd build

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:
* library to ``$CMAKE_INSTALL_PREFIX/lib``
* executables to ``$CMAKE_INSTALL_PREFIX/bin``
* The ``Memory.xml`` file to ``/usr/share/dfhack``

It has the usual installer wizard thing. 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.
----------- You'll also need a copy of Microsoft Visual C++ 2010. The Express version is sufficient.
Using mingw Grab it from Microsoft's site.

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 Build
and set things up nicely. =====
Open the ``build`` folder and double click the batch script there. This will eventually open
a cmake GUI window. Here, set CMAKE_INSTALL_PREFIX to your DF folder and set up any other
options you're interested in. Hit configure and generate, close the GUI.
You'll have to add ``C:\MinGW\`` to your PATH variable. This crates a folder under build/ that contains the solution files for MSVC.
Building When you open the solution, make sure you never use the Debug builds. Those aren't

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 from within MSVC will end up there! (and that's
wrong). Any changes to the build system should be done
by changing the CMakeLists.txt files and running ``cmake``!
-------------------------
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:
* If you're only after the library run ``make dfhack``.
* ``make`` will build everything.
* ``make expbench`` will build the expbench testing program and the
library.
* Some of the utilities and the doxygen documentation won't be
normally built. You can enable them by specifying some extra
CMake variables::
BUILD_DFHACK_DOCUMENTATION - generate the documentation (really bad)
BUILD_DFHACK_EXAMPLES - build tools from tools/examples
BUILD_DFHACK_PLAYGROUND - build tools from tools/playground
Example::
cmake .. -DBUILD_DFHACK_EXAMPLES=ON

it, use it in-source or add your own extensions. Contributing back to All the plugins can be found in the 'plugins' folder. There's no in-depth documentation
the dfhack repository is welcome and the right thing to do :) on how to write one yet, but it should be easy enough to copy one and just follow the pattern.
The most important parts of DFHack are the Core, Console, Modules and Plugins.
Rudimentary API documentation can be built using doxygen. * Core acts as the centerpiece of DFHack - it acts as a filter between DF and SDL and synchronizes the various plugins with DF.
* Console is a thread-safe console that can be used to invoke commands exported by Plugins.
* Modules actually describe the way to access information in DF's memory. You can get them from the Core. Most modules are split into two parts: high-level and low-level. Higl-level is mostly method calls, low-level publicly visible pointers to DF's data structures.
* Plugins are the tools that use all the other stuff to make things happen. A plugin can have a list of commands that it exports and an onupdate function that will be called each DF game tick.
Rudimentary API documentation can be built using doxygen (see build options with ``ccmake`` or ``cmake-gui``).
DFHack consists of variously licensed code, but invariably weak copyleft.
The main license is zlib/libpng, some bits are MIT licensed, and some are BSD licensed.
Feel free to add your own extensions and plugins. Contributing back to
the dfhack repository is welcome and the right thing to do :)

Layout for tools Memory research
---------------- ---------------
Tools live in the tools/ folder. There, they are split into three If you want to do memory research, you'll need some tools and some knowledge.
categories. In general, you'll need a good memory viewer and optionally something
to look at machine code without getting crazy :)
distributed
these tools get distributed with binary releases and are installed
by doing 'make install' on linux. They are supposed to be stable
and supported. Experimental, useless, buggy or untested stuff
doesn't belong here.
examples
examples are tools that aren't very useful, but show how DF and
DFHack work. They should use only DFHack API functions. No actual
hacking or 'magic offsets' are allowed.
playground
This is a catch-all folder for tools that aren't ready to be
examples or be distributed in binary releases. All new tools should
start here. They can contain actual hacking, magic values and other
nasty business.
------------------------
Modules - what are they?
------------------------
DFHack uses modules to partition sets of features into manageable
chunks. A module can have both client and server side.
Client side is the part that goes into the main library and is
generally written in C++. It is exposed to the users of DFHack.
Server side is used inside DF and serves to accelerate the client
modules. This is written mostly in C style.
There's a Core module that shouldn't be changed, because it defines the
basic commands like reading and writing raw data. The client parts for
the Core module are the various implementations of the Process
interface.
A good example of a module is Maps. Named the same in both client and
server, it allows accelerating the reading of map blocks.
Communication between modules happens by using shared memory. This is
pretty fast, but needs quite a bit of care to not break.

DF binaries on Linux.
argstream

Current external dependencies
-----------------------------
wide-character ncurses
used for the veinlook tool on Linux.
x11 libraries
used for sending key events on linux
Build-time dependencies

you need cmake to generate the build system and some configuration
headers
=========================
Memory offset definitions
=========================
The files with memory offset definitions used by dfhack can be found in the
data folder.
Using publicly known information and analyzing the game's data is preferred.

<p>The most important parts of DFHack are the Core, Console, Modules and Plugins.</p>
<ul class="simple">
<li>Core acts as the centerpiece of DFHack - it acts as a filter between DF and SDL and synchronizes the various plugins with DF.</li>
<li>Console is a thread-safe console that can be used to invoke commands exported by Plugins.</li>
<li>Modules actually describe the way to access information in DF's memory. You can get them from the Core. Most modules are split into two parts: high-level and low-level. Higl-level is mostly method calls, low-level publicly visible pointers to DF's data structures.</li>
<li>Plugins are the tools that use all the other stuff to make things happen. A plugin can have a list of commands that it exports and an onupdate function that will be called each DF game tick.</li>
</ul>
<p>Rudimentary API documentation can be built using doxygen (see build options with <tt class="docutils literal">ccmake</tt> or <tt class="docutils literal"><span class="pre">cmake-gui</span></tt>).</p>
<p>DFHack consists of variously licensed code, but invariably weak copyleft.
The main license is zlib/libpng, some bits are MIT licensed, and some are BSD licensed.</p>
<p>Feel free to add your own extensions and plugins. Contributing back to

<div class="section" id="modules-what-are-they">
<h3><a class="toc-backref" href="#id17">Modules - what are they?</a></h3>
<p>DFHack uses modules to partition sets of features into manageable
chunks. A module can have both client and server side.</p>
<p>Client side is the part that goes into the main library and is
generally written in C++. It is exposed to the users of DFHack.</p>
<p>Server side is used inside DF and serves to accelerate the client
modules. This is written mostly in C style.</p>
<p>There's a Core module that shouldn't be changed, because it defines the
basic commands like reading and writing raw data. The client parts for
the Core module are the various implementations of the Process
interface.</p>
<p>A good example of a module is Maps. Named the same in both client and
server, it allows accelerating the reading of map blocks.</p>
<p>Communication between modules happens by using shared memory. This is
pretty fast, but needs quite a bit of care to not break.</p>
