The errors are: make[5]: Entering directory `/home/stream/Projects/GStreamer/Git/gst-plugins-bad/gst-libs/gst/gl' CC libgstgl_1.0_la-gstgldisplay.lo gstgldisplay.c: In function 'gst_gl_display_new': gstgldisplay.c:115:30: error: variable 'platform_choice' set but not used [-Werror=unused-but-set-variable] const gchar *user_choice, *platform_choice; ^ cc1: all warnings being treated as errors make[5]: *** [libgstgl_1.0_la-gstgldisplay.lo] Error 1 </BLOCKQUOTE> <BLOCKQUOTE TYPE=CITE> If 'GST_GL_HAVE_PLATFORM_EGL' is not defined, then platform_choice is defined and set, but not used which with the configured compiling settings throws an error. If the setting of platform_choice is moved in under the '#if GST_GL_HAVE_PLATFORM_EGL' then the platform_choice is defined, but not used throwing an error. So that must be guarded as well by the 'GST_GL_HAVE_PLATFORM_EGL. </BLOCKQUOTE> It's used always if debug traces is enabled. So I suppose you disabled debug traces in your build and EGL is the only supported platform. if (!display) { /* subclass returned a NULL window */ GST_WARNING ("Could not create display. user specified %s, creating dummy", user_choice ? user_choice : "(null)"); This is a bit tricky/twisted to fix, please file a bug, bugs.gnome.org produce GStreamer component gst-plugins-bad. cheers, Nicolas </BODY> </HTML>
