Re: gstreamermm on windows

[Mikhail Titov <mlt gmx us>]

I gave a try to build gstreamermm using MS VC++ 2008 Express after I've
built GTKMM 3.1.8 and XML++ 2.34.1 libraries
(https://github.com/mlt/gtkmm in case someone feels like forking).
I was getting errors like the following:

C:\workspace\gtkmm\gstreamermm-0.10.10\gstreamer\gstreamermm/clock.h(55)
: error C2201: 'CLOCK_TIME_NONE' : must have external linkage in order
to be exported/imported

Line 55 of clock.h looks like

static GLIBMM_API const ClockTime CLOCK_TIME_NONE = GST_CLOCK_TIME_NONE;

Isn't it a generally bad idea to have variables in header file even
declared as static? And what was the purpose of GLIBMM_API anyway? It
compiled fine after I removed GLIBMM_API from those lines.

Now I'm having issue with caps.cc . It uses GstCapsIntersectMode but I
don't see this definition anywhere. Is gstreamer-0.10 from openSUSE
Build Service broken? How gstreamermm is compiled there then?
Surpsisingly enough gst.h doesn't contain anything with 'mode' in it.
Manual says it has been added in 0.10.33  whereas OBS has 0.10.32
however gstreamermm is labeled 0.10.10 . Why is there such inconsistency
with version numbers? Okay, I've rolled back to gstreamermm-0.10.9 and
compiled everything fine.

At the very end I realized that ogg example uses ALSA as a sink. Of
course I don't have ALSA on win32. What should I use as a sink when
using mingw cross-compiled binaries of gstreamer from openSUSE build
service? Most conversations I found with google contain either broken
links or badly old :-(

P.S. Is there any other source of cross-compiled win32 binaries like
those provided by openSUSE Build Service? In particular glib is outdated
in there and I don't feel like rebuilding entire stack for recent GTKMM
:( Also I'm hesitating on using OSSBuild for gstreamer.
