[Marble-devel] How to use the Navigation and OsmPlacemarkData classes?

[Kim Tore Jensen]

Hi list,

First of all, I admire your work with Marble. It is quite a powerful library,
thanks for developing and maintaining it.

I have some questions regarding compiling a program against the 16.04 version
of Marble. There are some header files referred to internally in the library,
but that are not being made available in /usr/include/marble. How can I access
the following classes?

    * Navigation, defined in src/lib/marble/declarative/Navigation.h
    * OsmPlacemarkData, defined in src/lib/marble/osm/OsmPlacemarkData.h

What I'm trying to achieve is to access the name of a placemark after running a
search with RouteRequest, and to get turn-by-turn directions. If there is some
other way to do this, I would be happy to know.

I am building Marble on Debian 8 (Jessie) on i686 using:

    cmake -DCMAKE_BUILD_TYPE=Release \
          -DWITH_KF5=FALSE \
          -DCMAKE_INSTALL_PREFIX=/usr \
          -DQTONLY=ON \
          -DBUILD_MARBLE_APPS=NO \
          -DWITH_DESIGNER_PLUGIN=NO \
          -DBUILD_MARBLE_TESTS=NO \
          /path/to/marble

The configuration output states:

    -- Could NOT find Phonon (missing:  PHONON_INCLUDE_DIR PHONON_LIBRARY)
