osgEarth 2.8 failed to build

[willysr]

I tested this on Slackware64-14.2 with following deps installed:

• OpenSceneGraph-3.4.0
• gdal-2.1.3
• geos-3.6.1
• proj-4.9.3

i was able to compile osgEarth 2.8 with GEOS 3.5.0

[gwaldron]

Thanks. I will open a new ticket for GEOS 3.6 support.

[filnet]

I submitted a PR to compile with geos 3.6.1

[willysr]

@filnet in which project? i don't see any PR in osgEarth's PR list

Are you looking in your own clone ?

The PR is here here #848
