Dear all, I found another corner case about compiling a 3rd party driver into ISAR and I need to execute a command at make level but as root. Unfortunately su cannot authenticate seamlessly and without the root permission the command fails. Suggestions? override_dh_auto_build: sudo cp -arf /usr/lib/modules/*/source/* /usr/lib/modules/*/build/ cp -arf /usr/lib/modules/*/source/* /usr/lib/modules/*/build/ $(MAKE) -n modules ${PARALLEL_MAKE} Thanks, R-
