Poco Linking issue in Android only

beginners
#1

Hi. I am using Poco::DateTime and Poco::Timespan in Openframeworks for OSX as well as IOS with no problems by adding

#include “Poco/DateTime.h”
#include “Poco/Timespan.h”
using Poco::DateTime;
using Poco::Timespan;

to the concerning header file.

However, when using the exactly same code in OF for Android, I get the following error:

Android Studio in osx: error:undefined reference to ‘Poco::Timespan::~Timespan()’

Android Studio in windows: fatal errror:'Poco/DOM/Document.h not found

OF version: 0_10_1.

Does anyone have any Inputs or Ideas?
