Can't compile example file-
tested on OF 0.8.4 and OF 0.9.3 in vs 2012 and 2015.

error C1083: Cannot open include file: 'zlib.h': No such file or directory

I am making repeated fast requests of new locations and eventually I will get this error

Request_url: http://cbk0.google.com/cbk?output=xml&ll=53.4113,-6.84177&dm=1
[ error ] ofxXmlSettings: pushTag(): tag "annotation_properties" not found
Status: 200

It happens on different locations as well. After this error I can only get very low resolution images. The connection speed does not change.

The following link doesn't work anymore. Seems like google has blocked it.

Hi. I'm new to openframeworks and c++. I was wondering if much work would need to be done to this addon to make it work with of 0.9.3?
On OSX10.11 using Xcode 7.3, having used the projector generator and embedded both the ofxStreetView and ofxXmlSettings addons, I'm getting the following errors:

In ofApp.h:
Field type 'ofxStreetView' is an abstract class.

More specifically this seems to relate to:

"Unimplemented pure virtual method 'getTexture' in 'ofxStreetView' 
"Unimplemented pure virtual method 'isUsingTexture' in 'ofxStreetView' 

In main.cpp:
No matching function for call to 'ofRunApp'

Cheers
