The solution is to replace all glib .dll, .h, .a, .lib by the last glib packages (2.18.4)  from <a href="http://www.gtk.org/download-windows.html">http://www.gtk.org/download-windows.html</a>. So : - install the 2 packages ( <a href="http://forja.rediris.es/frs/?group_id=96" target="_blank">http://forja.rediris.es/frs/?group_id=96</a>) - remove include/glib - remove glib .dll(s), .lib and .a (and .def) . I mean keep only gstreamer dev. - unzip glib glib_2.18.4-1_win32.zip and glib-dev_2.18.4-1_win32.zip There is no pb with this because of "acsendent compatibilty" of glib2.x.x. Note I advise you to rebuild everything by your self.
