This is because the static archive libraries needed for static linking are only in the -dev packages. This is a consequence of our choice to statically link Hamlib into WSJT-X, this is necessary as we need functionality that is not available in the versions of Hamlib available from distribution repositories. If I can get a patch to Hamlib accepted to add a --without-libusb configure option then I will recommend that WSJT-X builds use a Hamlib configured that way. For users that have libusb-1.0-dev installed then for now they can install libudev-dev as well since the Hamlib configure will automatically configure libusb-1.0. I'm not sure why the Hamlib build itself is not failing with link errors when it builds its own utilities in static link mode, perhaps it is managing to dynamically link libudev when the static archive is not available but that is not what it should do. For Windows this not an issue since even if libusb-1.0-dev is available it must be added to the Hamlib build manually and it has no other requirements anyway. 73 Bill G4WJS. ------------------------------------------------------------------------------ Transform Data into Opportunity.
