[osg-users] [build] GStreamer linker error on OSX El Capitan

Hi Chris,

In general I would say that GStreamer shouldn't be required for OSG
usage under OSX as there are native video plugins already.  Do you
specifically need the GStreamer plugin?  If not you should be able to
disable the build of the plugin by setting the paths that CMake sets
up for GStreamer headers etc. back to empty strings, this will tell
CMake GStreamer isn't there and the plugin won't be built.

If you want the plugin to be built then you'll need to track down
exactly what is going wrong.  From the output you posted the only
error I've spotted so far was:

    ld: library not found for -lgstreamer-1.0

Which suggests to me that the CMake find script is partially setting
up the paths and libs but not completely, or the OSG's plugin isn't
setting up the path to the library as required.  One way to get more
information from the build is to run make thus:

  make VERBOSE=1

Also have a look at the GSTREAMER_* variables that CMake sets up,
you'll find these in CMakeCache.txt.

Robert.
