Re: [Vala] gtk issues on mac

Thanks for that...I went in and manually added the paths to PKG_CONFIG_PATH:

PKG_CONFIG_PATH=/usr/local/Cellar/gtk+3/3.4.4/lib/pkgconfig:/usr/local/Cellar/cairo/1.12.6/lib/pkgconfig:/usr/local/Cellar/pixman/0.28.0/lib/pkgconfig:/usr/local/Cellar/fontconfig/2.10.1/lib/pkgconfig:/usr/local/Cellar/freetype/2.4.10/lib/pkgconfig:/usr/local/Cellar/libpng/1.5.13/lib/pkgconfig:/usr/X11/lib/pkgconfig

Got it to compile ok, now when I run it I get:

(VideoSample:76369): GStreamer-CRITICAL **: gboolean
gst_element_link_pads_full(GstElement *, const gchar *, GstElement *, const
gchar *, GstPadLinkCheck): assertion `GST_IS_ELEMENT (dest)' failed
Segmentation fault: 11
