Hello Bernd, I could further isolate the cmake failing issue. It starts failing when the package qtbase5-dev is installed. This gets installed as build dependency for libgps26.
A workaround would be to temporarily uninstall qtbase5-dev. Maybe better would be to add following to navit to allow building while qtbase5-dev is installed. Building that way produces equal .deb packages. Kind regards, Bernhard --- navit-0.5.3+dfsg.1.orig/debian/rules 2018-09-01 12:16:52.000000000 +0200 +++ navit-0.5.3+dfsg.1/debian/rules 2020-01-15 23:57:58.840074000 +0100 @@ -75,6 +75,9 @@ CMAKEFLAGS += -Dsupport/shapefile=TRUE # Enable libspeechd CMAKEFLAGS += -Dspeech/speech_dispatcher=TRUE +# Disable Qt explicitly to allow building while qtbase5-dev is installed +CMAKEFLAGS += -DDISABLE_QT=TRUE + # Avoid floating point calculation for armel ifeq ($(DEB_HOST_ARCH), armel) CMAKEFLAGS += -DAVOID_FLOAT=TRUE
