This readme covers VCMI compilation on Unix-like systems.
To run the game you will need:
1) Heroes 3 data files (SoD or Complete editions);
2) VCMI data pack (http://download.vcmi.eu/core.zip)
All of them can be installed manually or using vcmibuilder script
For complete installation instructions see VCMI wiki:
http://wiki.vcmi.eu/index.php?title=Installation_on_Linux#Preparing_data
I. Prerequisites
To compile, the following packages (and their development counterparts) are needed to build:
* libstdc++ devel
* CMake build system
* SDL and SDL-devel
* SDL_mixer and SDL_mixer-devel
* SDL_image and SDL_image-devel
* SDL_ttf and SDL_ttf-devel
* zlib and zlib-devel
* (optional) Qt 5, widget and network modules
* the ffmpeg libraries (libavformat and libswscale). Their name could be libavformat-devel and libswscale-devel, or ffmpeg-libs-devel or similar names.
* boost c++ libraries v1.48+ (www.boost.org):
- program-options
- filesystem
- system
- thread
- locale
On Debian-based systems (e.g. Ubuntu) run:
sudo apt-get install cmake g++ libsdl1.2debian libsdl-image1.2-dev libsdl-ttf2.0-dev libsdl-mixer1.2-dev zlib1g-dev libavformat-dev libswscale-dev libboost-dev libboost-filesystem-dev libboost-system-dev libboost-thread-dev libboost-program-options-dev libboost-locale-dev qtbase5-dev
On RPM-based distributions (e.g. Fedora) run:
sudo yum install cmake gcc-c++ SDL2-devel SDL2_image-devel SDL2_ttf-devel SDL2_mixer-devel boost boost-devel boost-filesystem boost-system boost-thread boost-program-options boost-locale zlib-devel ffmpeg-devel ffmpeg-libs
II. Getting the sources
VCMI is still in development. We recommend the following initial directory structure:
trunk
trunk/vcmi -> contains sources and is under git control
trunk/build -> contains build output, makefiles, object files,...
You can get latest sources with subversion:
git clone https://github.com/vcmi/vcmi.git
III. Compilation
Run configure:
mkdir build && cd build
cmake ../vcmi <any other options, see below>
Additional options that you may want to use:
To enable debugging: -DCMAKE_BUILD_TYPE=Debug
To change installation directory: -DCMAKE_INSTALL_PREFIX=$absolute_path_to_directory
Notice:
The ../vcmi/ is not a typo, it will place makefile scripts into the build dir
as the build dir is your working dir when calling CMake.
Then build vcmi:
make -j2 (j2 = compile with 2 threads, you can specify any value)
That will generate vcmiclient, vcmiserver, vcmilauncher as well as 3 .so libraries.
III. Installing binaries
To install VCMI you can use "make install" command however generation of distribution-specific packages is usually a better idea. In most cases this can be achieved using tool called "checkinstall"
If you're compiling vcmi for development puposes, the easiest is to use cmake prefix and then make install:
# mkdir .../trunk/install
# cmake -DCMAKE_INSTALL_PREFIX=.../trunk/install ../vcmi
# make && make install
# .../trunk/install/bin/vcmiclient
it's better to use links instead.
Go to /BIN_PATH/, and type:
ln -s .../trunk/build/client/vcmiclient
ln -s .../trunk/build/server/vcmiserver
ln -s .../trunk/build/launcher/vcmilauncher
Go to /LIB_PATH/vcmi, and type:
ln -s .../trunk/build/lib/libvcmi.so libvcmi.so
Go to /LIB_PATH/vcmi/AI, and type:
ln -s .../trunk/build/AI/VCAI/VCAI.so
ln -s .../trunk/build/AI/StupidAI/StupidAI.so
ln -s .../trunk/build/AI/BattleAI/BattleAI.so
Go to /DATA_PATH/vcmi, and type:
ln -s .../trunk/source/config
ln -s .../trunk/source/Mods
