I'm tring to compile the GStreamer backend for Phonon contained in the latest
Qt 4.4 snapshot qt-win-opensource-src-4.4.0-snapshot-20071216.zip from
ftp://ftp.trolltech.com/qt/snapshots/ on Windows XP.

I'm using the latest (08-Oct-2007) GStreamer packages for Windows from
http://gstreamer.freedesktop.org/pkg/windows/cvs/ with the MSVC 2005 Express
compiler.

The code compiles fine until linking:

gsthelper.obj : error LNK2019: unresolved external symbol
_gst_property_probe_probe_and_get_values referenced in function "public: static
class QStringList __cdecl
Phonon::Gstreamer::GstHelper::extractProperties(struct _GstElement *,class
QString const &)"
(?extractProperties at GstHelper@Gstreamer at Phonon@@SA?AVQStringList@@PAU_GstElement@@ABVQString@@@Z)

mediaobject.obj : error LNK2019: unresolved external symbol
_gst_tag_list_get_float referenced in function "void __cdecl
Phonon::Gstreamer::foreach_tag_function(struct _GstStructure const *,char const
*,void *)"
(?foreach_tag_function at Gstreamer@Phonon@@YAXPBU_GstStructure@@PBDPAX at Z)

mediaobject.obj : error LNK2019: unresolved external symbol
_gst_tag_list_get_boolean referenced in function "void __cdecl
Phonon::Gstreamer::foreach_tag_function(struct _GstStructure const *,char const
*,void *)"
(?foreach_tag_function at Gstreamer@Phonon@@YAXPBU_GstStructure@@PBDPAX at Z)

Using objdump to look at the exported symbols of libgstinterfaces-0.10.lib and
libgstreamer-0.10.lib shows, that not all functions from
gst/interfaces/propertyprobe.h and gst/gsttaglist.h are exported (output is
simplified):

objdump -t libgstinterfaces-0.10.lib | grep gst_property_
_gst_property_probe_get_properties
_gst_property_probe_get_property
_gst_property_probe_get_type
_gst_property_probe_get_values_name
_gst_property_probe_needs_probe_name
_gst_property_probe_probe_property_name

objdump -t libgstreamer-0.10.lib | grep gst_tag_list_get
_gst_tag_list_get_char
_gst_tag_list_get_date
_gst_tag_list_get_date_index
_gst_tag_list_get_double_index
_gst_tag_list_get_int
_gst_tag_list_get_string
_gst_tag_list_get_string_index
_gst_tag_list_get_tag_size
_gst_tag_list_get_type
_gst_tag_list_get_uint
_gst_tag_list_get_uint_index
_gst_tag_list_get_value_index

The symbols triggering the unresolved-external-symbol-errors are missing in
this list.
