Those are kernel headers, they *might* work in userspace but they're not designed to. Use the exported headers: CFLAGS += -I../../../../usr/include If they're not there, then the user can install them, or fall back to the system headers. > +CFLAGS += $(shell pkg-config --cflags mount) > +LDLIBS += $(shell pkg-config --libs mount) What if pkg-config isn't installed? cheers
