Building on Microsoft Windows

For general information, see wiki/Building first.

Building

The new build system is a work in progress, see #678 for details.

Steps:

• install ​mingw-w64
• run these commands:

  #choose your target build arch (or do each one in turn):
  #32-bit:
  #export XPKG="mingw-w64-i686-"
  #64-bit:
  export XPKG="mingw-w64-x86_64-"
  #most packages get installed here: (python, gtk, etc):
  pacman --noconfirm -S ${XPKG}python2 ${XPKG}python2-pygtk ${XPKG}gtkglext
  #media libraries (more than we actually need):
  pacman --noconfirm -S ${XPKG}ffmpeg ${XPKG}gst-plugins-good ${XPKG}gst-plugins-bad ${XPKG}gst-plugins-ugly
  #network layer libraries:
  pacman --noconfirm -S ${XPKG}lz4 ${XPKG}lzo2 ${XPKG}xxhash
  #python3 GStreamer bindings:
  pacman --noconfirm -S ${XPKG}gst-python
  #development tools and libs for building extra packages:
  pacman --noconfirm -S base-devel ${XPKG}yasm ${XPKG}nasm subversion rsync gtk-doc ${XPKG}cmake ${XPKG}gcc ${XPKG}pkg-config ${XPKG}libffi
  #python libraries and install and packaging tools:
  pacman --noconfirm -S ${XPKG}python2-numpy ${XPKG}python2-pillow ${XPKG}cython2 ${XPKG}python2-setuptools ${XPKG}python2-cx_Freeze
  #python3 versions (not all are really needed if just using python3 for sound):
  pacman --noconfirm -S ${XPKG}python3-numpy ${XPKG}python3-pillow ${XPKG}cython ${XPKG}python3-cx_Freeze
  #using easy-install for python libraries which are not packaged by mingw:
  for x in rencode xxhash netifaces lz4 websocket-client comtypes PyOpenGL PyOpenGL_accelerate websockify cffi pycparser cryptography nvidia-ml-py; do
      easy_install-2.7 -U -Z $x
      easy_install-3.5 -U -Z $x
  done
  #for webcam support:
  pacman -S ${XPKG}opencv ${XPKG}hdf5 ${XPKG}tesseract-ocr
  

Not covered here yet (see #678):

• pygtkglext: follow ticket:678#comment:27
• pygobject patching (minor)
• websockify
• CUDA / NVENC / pycuda
• install gsview and ghostscript (see wiki/Dependencies)

---

The old build system is very hard to setup: follow ​these instructions to build all the required dependencies (and trim the parts that are only relevant to ​winswitch)

Packaging

The MS Windows specific build scripts are here.

We use a combination of the setup.py file, BAT files and an innosetup script to generate the executable installer.
