Questions on MinGW configuration of GStreamer SDK Windows build

[4ernov]

Hello,

not sure if it's the right place for questions concerning GStreamer
SDK, but still here're some.

I have strange problems building helloworld Gst application using
MinGW and GStreamer SDK Windows build (2012.11): if I compile the
application using latest MinGW with gcc-4.7.2 and Dwarf2 exception
model it fails to start with message about undefined symbol
__gxx_personality_sj0 in libstdc++6. As I found out, it could mean
that GStreamer SDK itself compiled using gcc with sjlj exception
model. I still can't understand how C++ exceptions and libstdc++6
concerned pure C program and libraries.

Then I found another MinGW build with gcc-4.6.2 and sjlj exception
model. I've tried to build another application which also depends on
Qt4, which I build with this MinGW version, too. As a result I failed
to build my project due to compilation error, somehow pthread.h in
GStreamer's include directory requires nanosleep() existance in time.h
in MinGW and somehow fails to find it. Maybe, the reason is that MinGW
version GStreamer SDK was built against has also another threading
model.

So, there're two questions:
1. What exception and threading model of MinGW version which GStreamer
SDK (2012.11 in particular) was built against?
2. Is there any problems with building the SDK using latest MinGW stable build?

I think, it would be nice to either point out build configuration on
gstreamer.com or prepare several builds with different exception
models. It seems to be so important information if one wouldn't build
applications with Visual Studio and prefer MinGW.

Thanks,
