Re: [Vala] gtk issues on mac



(linking back to the list)

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

Yes it is Mac OS X, 10.7.4.  I do have gtk+ and gtk+3 installed, via
homebrew.  I can actually see the gtk.h file
at /usr/local/Cellar/gtk+3/3.4.4/include/gtk-3.0/gtk/gtk.h.

valac uses pkg-config to find out which compiler/linker flags to pass.
Check to make sure pkg-config is reporting the correct flags
(`pkg-config --libs --cflags`).  You'll either have to fix pkg-config or
pass the correct flags manually (using valac -X). The way to fix this
particular problem would be passing -X -I/usr/local/Cellar/gtk
+3/3.4.4/include/gtk-3.0 to valac, but you're likely to run into a lot
of similar issues, so I would advise you figure out what is going on
with pkg-config if possible.

Note that incorrect flags from pkg-config isn't really a Vala-specific
issue.  You should be able to get help from a forum for whatever you
used to install GTK+ on OS X, and you might have better luck there since
most people on this list are unlikely to be very knowledgeable about OS
X.

You don't seem to have Gtk installed? Also, is it on Mac OS X?

I'm new to Vala, and trying to run the "Vala GStreamer Video Example"
(found here:  https://live.gnome.org/Vala/GStreamerSample) on a mac.
 When
I attempt to compile the program using the command:

(Note that I am using Vala 0.17.5, installed via Homebrew):

valac --pkg gtk+-3.0 --pkg gdk-x11-3.0 --pkg gstreamer-0.10 --pkg
gstreamer-interfaces-0.10 VideoSample.vala

I receive the error:

If I try to change it to use gtk2.0:

valac --pkg gtk+-2.0 --pkg gdk-x11-2.0 --pkg gstreamer-0.10 --pkg
gstreamer-interfaces-0.10 VideoSample.vala

I get a different error:

Thanks in advance, any help is definitely appreciated.
