Hello Bernd, my navit know-how is also limited, but I remebered I saw this while having build-deps of navit and libgps installed. Below are the packages which got installed additionally in a minimal test VM on top of navit's build-deps.
If there are just build-deps's of navit installed the build runs fine until the compile error given in message 18. For this I made this (to be checked) change: - priv->fix_time = data->fix.time; + priv->fix_time = data->fix.time.tv_sec; Kind regards, Bernhard apt build-dep libgps26 asciidoc asciidoc-base asciidoc-common bc dh-apparmor dh-buildinfo dh-exec dh-python docbook-xml docbook-xsl libbluetooth-dev libbluetooth3 libdouble-conversion3 libegl-dev libegl-mesa0 libegl1 libevdev2 libgbm1 libgudev-1.0-0 libinput-bin libinput10 libmtdev1 libncurses-dev libpython3-all-dbg libpython3-all-dev libpython3-dbg libpython3-dev libpython3.7-dbg libpython3.7-dev libpython3.8 libpython3.8-dbg libpython3.8-dev libpython3.8-minimal libpython3.8-stdlib libqt5concurrent5 libqt5core5a libqt5dbus5 libqt5gui5 libqt5network5 libqt5printsupport5 libqt5sql5 libqt5test5 libqt5widgets5 libqt5xml5 libusb-1.0-0-dev libvulkan-dev libvulkan1 libwacom-common libwacom2 libwayland-client0 libwayland-server0 libxcb-icccm4 libxcb-image0 libxcb-keysyms1 libxcb-randr0 libxcb-render-util0 libxcb-shape0 libxcb-util0 libxcb-xfixes0 libxcb-xinerama0 libxcb-xinput0 libxcb-xkb1 libxkbcommon-x11-0 libxkbcommon0 libxslt1.1 makedev pps-tools python3-all python3-all-dbg python3-all-dev python3-dbg python3-dev python3.7-dbg python3.7-dev python3.8 python3.8-dbg python3.8-dev python3.8-minimal qt5-qmake qt5-qmake-bin qtbase5-dev qtbase5-dev-tools qtchooser scons sgml-base sgml-data xml-core xsltproc
