Prerequisites



  • Qt5 bundle download
  • Boost libraries download (<=1.55, Boost 1.56 has error and incompatible)

Create initial directory

Create a directory for VCMI development, eg. C:\VCMI We will call this directory as [VCMIBUILD_DIR]

It is recommended to avoid non-ascii characters in the path to your VCMI development folder. The folder should not be write-protected by system. Good location:

  • C:\VCMI

Bad locations:

  • C:\Users\Michał\VCMI (non-ascii character)
  • C:\Program Files (x86)\VCMI (write protection)

Preparing place

Clone VCMI

Install Qt bundle

  • Run installer
  • Select latest Qt for mingw and mingw 4.8.2 from tools
  • Select [VCMIBUILD_DIR]/qt as destination folder
  • Install
  • Add [VCMIBUILD_DIR]/Qt/Tools/mingw482_32/bin to PATH system variable.

Unpack libraries

  • Download libraries pack and unpack it in [VCMIBUILD_DIR]/depends folder

So, you should get

  • [VCMIBUILD_DIR]
    • depends
      • bin
      • include
      • lib
      • share

Compiling

Create toolchain file

Create [VCMIBUILD_DIR]/toolchain.txt 

SET(CMAKE_SYSTEM_NAME Windows)
SET(VCMIBUILD_DIR [ENTER YOUR VCMIBUILD_DIR PATH])

SET(CMAKE_C_COMPILER   ${VCMIBUILD_DIR}/Qt/Tools/mingw482_32/bin/gcc.exe)
SET(CMAKE_CXX_COMPILER ${VCMIBUILD_DIR}/Qt/Tools/mingw482_32/bin/g++.exe)

SET(ENV{BOOST_ROOT} ${VCMIBUILD_DIR}/boost)

SET(CMAKE_FIND_ROOT_PATH  ${VCMIBUILD_DIR}/depends)
list(APPEND CMAKE_PREFIX_PATH ${CMAKE_FIND_ROOT_PATH})
list(APPEND CMAKE_PREFIX_PATH ${VCMIBUILD_DIR}/Qt/5.3/mingw482_32)

SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM BOTH)
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY BOTH)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE BOTH)

Compile boost

  • Unpack boost archive
  • Execute
bootstrap.bat mingw
b2 toolset=gcc --without-python --stage
  • copy stage/lib to [VCMIBUILD_DIR]/boost/lib
  • copy boost dir to [VCMIBUILD_DIR]/boost/boost

So, you should get

  • [VCMIBUILD_DIR]
    • boost
      • boost
      • lib

Compile VCMI

  • Open CMake-gui
  • Select [VCMIBUILD_DIR]/vcmi/source as source directory
  • Select [VCMIBUILD_DIR]/vcmi/binary as binary directory
  • click "Configure"
  • Select "MinGW makefiles" in combobox
  • Select "Specify toolchain file for crosscompiling"
  • Select toolchain file
  • Set variables:
    • CMAKE_INSTALL_PREFIX = [VCMIBUILD_DIR]/vcmi/result
    • ENABLE_PCH = OFF (because of cc1plus.exe crash)
  • click Configure
  • click Generate
  • go to [VCMIBUILD_DIR]/vcmi/binary directory
  • execute mingw32-make
  • execute mingw32-make install
  • Grab VCMI in [VCMIBUILD_DIR]/vcmi/result folder!

Appendix A. Libraries compilation

How to compile ZLib yourself

  • Unpack archive to temp folder, for example, [VCMIBUILD_DIR]/zlib/src
  • Open CMake-gui
  • Select [VCMIBUILD_DIR]/zlib/src as source directory
  • Select [VCMIBUILD_DIR]/zlib/bin as binary directory
  • click "Configure"
  • Select "MinGW makefiles" in combobox
  • Select "Specify toolchain file for crosscompiling"
  • Select toolchain file
  • Set variables:
    • INSTALL_BIN_DIR = [VCMIBUILD_DIR]/depends/bin
    • INSTALL_INC_DIR = [VCMIBUILD_DIR]/depends/include
    • INSTALL_LIB_DIR = [VCMIBUILD_DIR]/depends/lib
    • INSTALL_MAN_DIR = [VCMIBUILD_DIR]/depends/share/man
    • INSTALL_PKGCONFIG_DIR = [VCMIBUILD_DIR]/depends/share/pkgconfig
  • click Configure
  • click Generate
  • go to [VCMIBUILD_DIR]/zlib/bin directory
  • execute mingw32-make
  • execute mingw32-make install

How to compile FFmpeg yourself

  • Download FFmpeg source tarball(link) and unpack it to temp folder, for example, [VCMIBUILD_DIR]/ffmpeg/source
  • Download Msys2 (link) and install it
  • Open Msys2
  • execute pacman -Syu and restart Msys2
  • execute pacman -S make yasm
  • Go to /c/[VCMIBUILD_DIR]/ffmpeg/source folder
  • Execute
./configure --disable-doc --target-os=mingw32 --enable-shared --prefix=/c/[VCMIBUILD_DIR]/depends
make 
make install
