Here's how you build dfhack!
----------------------------
First, there is one dependency, regardless of the OS you use:
2009-09-13 18:02:46 -06:00
cmake - it's the build system
2009-10-30 03:01:14 -06:00
Building on Linux:
--------------------
* To run in the output folder (without installing):
2009-09-13 18:02:46 -06:00
2009-10-30 03:01:14 -06:00
building the library is simple. Enter the build folder, run the tools. Like this:
cd build
2010-01-18 13:50:44 -07:00
cmake .. -DCMAKE_BUILD_TYPE:string=Release
2009-10-30 03:01:14 -06:00
make
2009-09-13 18:02:46 -06:00
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.
2009-10-30 03:01:14 -06:00
* 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:
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 that: 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!
2009-09-13 18:02:46 -06:00
* 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.
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 40d15 - 40d17 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't be debugged, because debug builds in MSVC use a different CRT!
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 lost.

Build targets
-------------
2009-09-13 18:02:46 -06:00
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 throughput testing program and the library.
2009-09-13 18:02:46 -06:00
Build types
-----------
2009-09-13 18:02:46 -06:00
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 build types include 'Release' and 'Debug'. There are others, but they aren't really that useful.
Have fun.
