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.
+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.
+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.
To run in the output folder (without installing) building the library -is simple. Enter the build folder, run the tools. Like this:
+Building is fairly straightforward. Enter the build folder and start the build like this:
cd build -cmake .. -DCMAKE_BUILD_TYPE:string=Release -make +cmake .. -DCMAKE_BUILD_TYPE:string=Release -DCMAKE_INSTALL_PREFIX=/home/user/DF +make install-
This will build the library and its tools and place them in a sub-directory bin inside your build directory.
+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:
-++make install +cd build ccmake .. -make
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.
-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 --

First, 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.
-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.
-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 --
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!
-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.
-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. +Grab it from Microsoft's site.
+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.
+This crates a folder under build/ that contains the solution files for MSVC.
+When you open the solution, make sure you never use the Debug builds. Those aren't +binary-compatible with DF. If you try to use a debug build with DF, you'll only get crashes. +So pick either Release or RelWithDebInfo build and build the INSTALL target.
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 --
cmake allows you to pick a build type by changing this variable: CMAKE_BUILD_TYPE

Currently, the only way to use the library is to write a plugin that can be loaded by it. +All the plugins can be found in the 'plugins' folder. There's no in-depth documentation +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 (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 :)
-Rudimentary API documentation can be built using doxygen.
Several things should be kept in mind when contributing to DFHack.
DFhack uses ANSI formatting and four spaces as indentation. Line endings are UNIX. The files use UTF-8 encoding. Code not following this won't make me happy, because I'll have to fix it. There's a good chance I'll make you fix it ;)
You can send patches or make a clone of the github repo and ask me on the IRC channel to pull your code in. I'll review it and see if there are any problems. I'll fix them if they are minor.

-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.
-If you want to add dependencies, think twice about it. All internal -dependencies for core dfhack should be either public domain or require -attribution at most. External dependencies for tools can be either -that, or any Free Software licenses.
