            Bug ID: 771029
           Summary: MSVC can't link against autotools-build generated DLLs
    Classification: Platform
           Product: GStreamer
           Version: 1.9.2
                OS: Windows
            Status: NEW
          Severity: major
          Priority: Normal
         Component: gstreamer (core)
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: scott.d.phillips at intel.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

The change
https://cgit.freedesktop.org/gstreamer/gstreamer/commit/gst/gstconfig.h.in?id=22b892b44f5005d7af8d50df313e759bfdb1acd0
has it so autotools-generated gstconfig.h won't ever expand GST_EXPORT to
__declspec(dllimport) in user-of-gstreamer builds.

I'm not an expert on windows object linking so maybe it was somehow subtly
broken before, and not working at all is better? But if I change the expanded
GSTCONFIG_USE_MSVC_DECLSPEC in gstconfig.h from '0' to '1' in the released
1.9.2 gstreamer devel package, then I am able to build a plugin with MSVC that
can also work at runtime.
