I am having a little trouble getting my Ruby on Rails app to recognise the GEOS installation on Ubuntu 14.04.
The error message that I am getting is;
GEOS is not available, but is required for correct interpretation of polygons in shapefiles.
I'm using the 'rgeo' gem and I understand this to mean (from my own Googling) that rgeo can't find the GEOS installation.
Indeed, via the Rails console, this is confirmed;
Loading production environment (Rails 4.2.1)
2.1.2 :001 > RGeo::Geos.supported?
=> false
2.1.2 :002 > RGeo::CoordSys::Proj4.supported?
=> true
I initially followed these instructions to get GEOS / Proj4 installed;

When that didn't work I found this post;
https://github.com/rgeo/rgeo/issues/26
And added the recommended symlinks;
-rw-r--r-- 1 root root 1588288 Apr 7 2014 /usr/lib/libgeos-3.4.2.so
-rw-r--r-- 1 root root 259680 Apr 7 2014 /usr/lib/libgeos_c.a
lrwxrwxrwx 1 root root 18 Apr 7 2014 /usr/lib/libgeos_c.so -> libgeos_c.so.1.8.2
lrwxrwxrwx 1 root root 18 Apr 7 2014 /usr/lib/libgeos_c.so.1 -> libgeos_c.so.1.8.2
-rw-r--r-- 1 root root 146632 Apr 7 2014 /usr/lib/libgeos_c.so.1.8.2
lrwxrwxrwx 1 root root 31 Jul 4 11:30 /usr/lib/libgeos.so -> /usr/local/lib/libgeos-3.3.8.so
lrwxrwxrwx 1 root root 31 Jul 4 11:35 /usr/lib/libgeos.so.1 -> /usr/local/lib/libgeos-3.3.8.so
And despite all of this I still get
RGeo::Geos.supported?
returning 'false'.
I get the feeling that this shouldn't be this hard (and that I am missing something elementary) - but am at a bit of a loss.
Any help would be greatly appreciated. :)
Thanks in advance, Ben
