           Summary: Linking static directx libraries to gstdirect* plugins
                    on Windows
           Product: GStreamer
           Version: git
          Platform: Other
        OS/Version: Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good

     GNOME version: Unspecified
   GNOME milestone: Unspecified


gstdirectdrawsink and gstdirectsoundsink depend on libdxguid.a and libdxerr9.a
Both .a files are static libraries (not import libraries) and do not have
corresponding .dll files. According to libtool, they can only be linked to
applications (executables), but not to .dlls, since linking static library to
shared library may have unpleasant consequences on most OSes. Fortunately,
gstdirecdrawsink and gstdirectsoundsink are THE cases when it is safe to link
static library - there's no possibility of symbol duplication, they are C-only
(right?) and PIC doesn't matter because .dlls don't support PIC. Unfortunately,
libtool developers are aiming to be cross-platform and do not wish to implement
features in libtool that are exclusive for some platforms (such as Win32).
Because of that libtool can't (and won't) allow us to link these libraries to
these plugins.

Roumen Petrov suggested that one can pass library dependencies via "-Wl,"
syntax, in which case they are ignored by libtool.
