The above crash is in "graphics_qt_qpainter_new()" caused by
#ifndef QT_QPAINTER_USE_FREETYPE
#define QT_QPAINTER_USE_FREETYPE 1
#endif
found in "graphics_qt_qpainter.h", probably due to the assumption that
QT runs in X11 environment featuring XOrg's freetype font system which
is under MacOSX Aqua usually not the case.
Having fixed this, the next problem:
navit:plugin_load:can't load
'/usr/local/navit/lib/navit/vehicle/libvehicle_gpsd.so', Error
'dlopen(/usr/local/navit/lib/navit/vehicle/libvehicle_gpsd.so, 2):
Symbol not found: _gps_data
Referenced from: /usr/local/navit/lib/navit/vehicle/libvehicle_gpsd.so
Expected in: flat namespace
'
which suggests that /usr/local/gpsd/lib/libgps.dylib is not loaded by
dlopen() or something.
Though, if I specify a "demo" vehicle instead of "gpsd" in navit.xml,
then a navit window appears, with a fat red road in the middle with some
thinner streets visible as well, on a green background; though showing a
busy "rainbow" cursor, so all one can do is to hit Ctrl-C in a terminal
window. (But it is a success anyways to be at this point.) :-)
