How to build VCMI (Linux/Cmake/MXE)
From VCMI Project Wiki
Compiling VCMI for Windows on Linux
Some developers may want to make Windows builds without dealing with dependencies as it may be headache when you're on Windows. It's possible to setup own cross-compiler toolkit that use MinGW, but that take time and skill. Fortunately there is project called MXE (M cross environment) that make cross compilation easy and work out of box for our engine.
Setting up a MXE cross compiler
Make sure cmake and git is installed on your system as well as all libraries and utils listed under requirements. MXE website have commands that will let install everything needed for almost every distribution.
Once it done clone MXE using git. Then you need to edit "settings.mk" file:
# "settings.mk" not exist by default # You can create it by running "make" and then aborting it by Ctrl+C # # Uncomment "MXE_TARGETS" and make it look like that: MXE_TARGETS := i686-w64-mingw32.shared
Then you can compile it:
make MXE_PLUGIN_DIRS=plugins/gcc6 -j 9 gcc boost zlib sdl2 sdl2_gfx sdl2_image sdl2_mixer sdl2_ttf ffmpeg qt5
Depend on your hardware that may take from 20 minutes to more than hour.
Removing "Qt 5" that only used for launcher will drastically reduce compile time:
make MXE_PLUGIN_DIRS=plugins/gcc6 -j 9 gcc boost zlib sdl2 sdl2_gfx sdl2_image sdl2_mixer sdl2_ttf ffmpeg
Compiling VCMI using MXE
First of all create two directories: one for CMake (vcmi-cmake) and other for result build (vcmi-build). Now build would looks like that:
# Clone VCMI repository git clone https://github.com/vcmi/vcmi.git # Create CMake directory and cd into it mkdir vcmi-cmake && cd vcmi-cmake # To build with launcher: cmake ../vcmi \ -DCMAKE_TOOLCHAIN_FILE=/home/test/mxe/usr/i686-w64-mingw32.shared/share/cmake/mxe-conf.cmake \ -DCMAKE_INSTALL_PREFIX=/home/test/vcmi-build \ -DENABLE_TEST=0 # Without launcher: cmake ../vcmi \ -DCMAKE_TOOLCHAIN_FILE=/home/test/mxe/usr/i686-w64-mingw32.shared/share/cmake/mxe-conf.cmake \ -DCMAKE_INSTALL_PREFIX=/home/test/vcmi-build \ -DENABLE_TEST=0 \ -DENABLE_LAUNCHER=0 # Compile make -j 9 # Move binaries into target directory make install
Script for automatic builds
If you want to have automatic build you can grab script that automatically compile and upload builds using MXE.
