GUPnP on Win32

As I stated earlier in GUPnP on win32 I’m currently porting the GUPnP stack to Windows. At first I tried an approach of developing on Linux, running autogen there and copying the whole tree to a Windows share, run ./configure and make there an see what breaks (or works)

After a while this gets quite annoying, so I tried to setup a complete build environment on Windows; you need:

Basic tools

• You’ll need an editor, of course

Basic win32 build environment

• mingw
• msys

Install mingw and msys as advised on the mingw homepage.

Gtk/Gnome libs and build dependencies

• The gtk win32 bundle

Extract this anywhere you like, just make sure you can access it from your mingw environment (/opt/gtk e.g.). Navigate to /opt/gtk/share/icons, copy the gnome directory to higcolor. Change the theme name in file highcolor/index.theme to highcolor. Otherwise the gupnp-tools (mainly the two control points) will not work.

Chain up everything

1. I decided to put all gupnp stuff in another directory (/opt/gupnp)
2. Move the old libtool.m4 and ltdl.m4 out of the way (/share/aclocal)
3. create /share/aclocal/dirlist and add /usr/local/aclocal as well as /opt/gtk/share/aclocal there
4. For libtool to work properly you need a file command. There’s no need for a full-blown implementation. The fake file available at http://trac.nexusformat.org/code/browser/trunk/file.MinGW is sufficient.
5. Create a .profile file containing the following lines:

   export PKG_CONFIG_PATH=/opt/gtk/lib/pkgconfig:/opt/gupnp/lib/pkgconfig:$PKG_CONFIG_PATH
   export LD_LIBRARY_PATH=/opt/gtk/lib:/opt/gupnp/lib:$LD_LIBRARY_PATH
   export PATH=/opt/gtk/bin:/opt/gupnp/bin:$PATH
   export ACLOCAL_FLAGS="-I /opt/gtk/share/aclocal -I /opt/gupnp/share/aclocal"

Additional dependencies

• libxml2: There is an official win32 build of this available at http://www.zlatkovic.com/libxml.en.html. Unfortunately it is missing the import libraries and pkg-config file for usw with mingw. Follow the instructions on http://www.go-evolution.org/Building_Evolution_on_Windows#libxml2 to create those. pexports is available here: http://www.emmestech.com/software/pexports-0.43/download_pexports.html
• iconv: Download iconv from here: http://www.gtk.org/download-windows.html. I chose win_iconv.
• gnome-icon-theme: download both packages from here: http://ftp.gnome.org/pub/GNOME/binaries/win32/gnome-icon-theme/2.24/. Extract them to /opt/gtk. Navigate to /opt/gtk/share/icons and copy gnome to highcolor. In the highcolor directory change index.theme in section [Icon Theme] the key Name to highcolor. You can remove all the other translations if you like. This is necessary for the gupnp control points to run later

Building the GUPnP stack

Some parts of GUPnP for windows currently only exists as git branches on github or gitorious. There is no release and no ready-to-build tarball of gssdp or gupnp. So you will need a version of git for windows. I’m using msysgit (http://code.google.com/p/msysgit/).

For the steps now following make sure you’re not in a directory containing spaces. There seems to be a (minor) problem with autoconf if you do. So let’s get started. First package is easy:

• libsoup: Download latest release from here: http://ftp.gnome.org/pub/GNOME/sources/libsoup/2.26/. Just run ./configure –prefix /opt/gupnp.
• gssdp: use git to get a copy from github: git clone git://github.com/phako/gssdp-win32.git
autogen.sh --prefix=/opt/gupnp && make && make install
• gupnp: git clone git://gitorious.org/~phako/gupnp/phako-gupnp.git
autogen.sh --prefix=/opt/gupnp && make && make install
• gupnp-av: Latest release contains windows support
• gupnp-tools: Latest release contains windows support

Using VS 2005/2008
I’m currently in the progress of defining solutions, projects and property pages for the GUPnP stack to be able to compile it (and even more important debug it) from within Visual Studio. A tiny preview of that can be seen here.
