Compiling DFHACK
################
============================
Here's how you build dfhack!
============================
.. contents::
Dependencies
============
* ``cmake``
* 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
=================
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:
* library to ``$CMAKE_INSTALL_PREFIX/lib``
* executables to ``$CMAKE_INSTALL_PREFIX/bin``
* The ``Memory.xml`` file to ``/usr/share/dfhack``
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
2010-08-12 19:31:05 -06:00
projects from within MSVC 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!
-------------------------
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.
2010-08-09 17:21:47 -06:00
* 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
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.
2010-08-12 19:31:05 -06:00
For DF 31.01 - 31.12 on Windows, use MSVC 2008. You can get the Express
edition for free from Microsoft.
