Error building for android: “ invalid use of incomplete type 'class Poco::Path'”

Hi,

I am trying to build an android application with OF. The application runs in two other computers. However, it does not work on mine. I am using a mac.

I run the command "make AndroidDebug" in the project folder, and this is the error I have:

/Library/openFrameworks/addons/ofxHTTP/libs/ofxHTTP/src/PostRouteFileHandler.cpp:98:46: error: invalid use of incomplete type 'class Poco::Path'
                 ss << Poco::Path(formFileName).getExtension();

I have installed poco, but nothing changes afterwards.

What can I do to solve this?
Thanks,
jl
