Using Ubuntu 16.04 the prebuild binaries you download/install using 'make osg_install osearth_install' do not match your system.
You need to build your own osg/osgearth or at least osg.

From ./make/3rdparty/osgearth/README.TXT :

Code: [Select]

$ sudo apt-get install libzip-dev libpng-dev lipjpeg-dev libtiff5-dev libcurl4-openssl-dev
$ sudo apt-get install libgeos++-dev libgdal-dev

$ sudo apt-get build-dep openscenegraph
Next step take time for osg/osgearth compilation.

Code: [Select]

# Clone and build 3rdparty osg and osgearth
make all_osg

# Copy the built osg and osgearth into tools directory for future use
cp -R build/3rdparty/install/osg*[.0-9][0-9] tools/

# Create a config file that allows GCS to have osgearth PFD instead of simple PFD
echo "override GCS_EXTRA_CONF=osg osgearth copy_osg" > config

Remove 'osgearth' from config file created at root if you do not want terrain capabilities / Osgearth in PFD

Now you should be able to build your gcs like previously.
