----------------------------------------------------------------------
Libraries have been installed in:
   /usr/local/src/cphalcon/build/64bits/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Have you tried changing

->columns('Office., Address.')

to this:

->columns(['Office.', 'Address.'])

In the Query Builder Docs the examples show a string being used as the paramter only when a single column parameter (including "*") is requested. When multiple column parameters are requested, it uses an array of columns.

Examples:

// 'SELECT * FROM Robots';
$phql = $builder->columns('*')
                ->from('Robots');

// 'SELECT id FROM Robots';
$builder->columns('id')
        ->from('Robots');

// 'SELECT id, name FROM Robots';
$builder->columns(array('id', 'name'))
        ->from('Robots');
