Compiling VCMI

  • Current baseline requirement for building is Ubuntu 14.04
  • Supported C++ compilers for UNIX-like systems are GCC 4.8+ and Clang 3.4+

Older distributions and compilers might work, but they aren't tested by Travis CI

Installing dependencies

Prerequisites

To compile, the following packages (and their development counterparts) are needed to build:

  • CMake 2.8.12 or newer
  • SDL2 with devel packages: mixer, image, ttf
  • zlib and zlib-devel
  • Optional of launcher: Qt 5, widget and network modules
  • 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+: program-options, filesystem, system, thread, locale

Manual Installation

For older OS versions the latest prerequisite packages may not be readily available via the system installer. Some brief instructions for manual install are given below (tested on Ubuntu 14.04, update version numbers as desired). 

wget https://cmake.org/files/v3.11/cmake-3.11.0.tar.gz
tar xfz cmake-3.11.0.tar.gz
cd cmake-3.11.0
./bootstrap
make -j2
sudo make install

Note: Will only be visible in new terminals. Test with cmake --version. 

wget https://dl.bintray.com/boostorg/release/1.66.0/source/boost_1_66_0.tar.gz
tar xfz boost_1_66_0.tar.gz
cd boost_1_66_0
./boostrap.sh --with-library=program-options,filesystem,system,thread,locale
./b2
./b2 install

On Debian-based systems (e.g. Ubuntu)

sudo apt-get install cmake g++ libsdl2-dev libsdl2-image-dev libsdl2-ttf-dev libsdl2-mixer-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

Alternatively if you have VCMI installed from repository or PPA you can use: 

sudo apt-get build-dep vcmi

On RPM-based distributions (e.g. Fedora)

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 qt5-qtbase-devel

On Arch-based distributions

On Arch-based distributions, there is a development package available for VCMI on the AUR.

It can be found at: https://aur.archlinux.org/packages/vcmi-git/

Information about building packages from the Arch User Repository (AUR) can be found at the Arch wiki.

Getting the sources

VCMI is still in development. We recommend the following initial directory structure: 

.
├── vcmi -> contains sources and is under git control
└── build -> contains build output, makefiles, object files,...

You can get latest sources with: 

git clone -b develop --depth 1 --recursive https://github.com/vcmi/vcmi.git

Compilation

Configuring Makefiles

mkdir build && cd build
cmake ../vcmi

# Additional options that you may want to use:
## To enable debugging:
cmake ../vcmi -DCMAKE_BUILD_TYPE=Debug

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.

Trigger build

cmake --build . -- -j2
# -j2 = compile with 2 threads, you can specify any value

That will generate vcmiclient, vcmiserver, vcmilauncher as well as 4 .so libraries in build/bin/ directory.

Package building

RPM package

The first step is to prepare a RPM build environment. On Fedora systems you can follow this guide: http://fedoraproject.org/wiki/How_to_create_an_RPM_package#SPEC_file_overview

1. Download the file rpm/vcmi.spec from any tagged VCMI release for which you wish to build a RPM package via the SVN Browser trac at this URL for example(which is for VCMI 0.9): http://sourceforge.net/apps/trac/vcmi/browser/tags/0.9/rpm/vcmi.spec

2. Copy the file to ~/rpmbuild/SPECS

3. Follow instructions in the vcmi.spec. You have to export the corresponding SVN tag, compress it to a g-zipped archive and copy it to ~/rpmbuild/SOURCES. Instructions are written as comments and you can copy/paste commands into terminal.

4. Go to ~/rpmbuild/SPECS and open terminal in this folder and type: 
rpmbuild -ba vcmi.spec (this will build rpm and source rpm)

5. Generated RPM is in folder ~/rpmbuild/RPMS

If you want to package the generated RPM above for different processor architectures and operating systems you can use the tool mock. Moreover, it is necessary to install mock-rpmfusion_free due to the packages ffmpeg-devel and ffmpeg-libs which aren't available in the standard RPM repositories(at least for Fedora). Go to ~/rpmbuild/SRPMS in terminal and type: 

mock -r fedora-17-i386-rpmfusion_free path_to_source_RPM
mock -r fedora-17-x86_64-rpmfusion_free path_to_source_RPM

Available root environments and their names are listed in /etc/mock.

Debian/Ubuntu

1. Install debhelper and devscripts packages

2. Run dpkg-buildpackage command from vcmi source directory 

sudo apt-get install debhelper devscripts
cd /path/to/source
dpkg-buildpackage

To generate packages for different architectures see "-a" flag of dpkg-buildpackage command

Documentation

To compile using Doxygen, the UseDoxygen CMake module must be installed. It can be fetched from: http://tobias.rautenkranz.ch/cmake/doxygen/

Once UseDoxygen is installed, run: 

cmake .
make doc

The built documentation will be available from ./doc
