http://ubuntuforums.org – Hi My first post. I'm pretty much a complete noob with Linux. I'm trying to compile and program which I've found. I'm a professional .Net developer, so have a good development understanding. I'm compiling this program here: http://www.gniibe.org/oitoite/ac-pow...hub/hub-ctrl.c This is my makefile: Quote: # build hub-ctrl executable when user executes "make" hub-ctrl: hub-ctrl.o $(CC) $(LDFLAGS) hub-ctrl.o -o hub-ctrl hub-ctrl.o: hub-ctrl.c $(CC) $(CFLAGS) -c hub-ctrl.c # remove object files and executable when user executes "make clean&quo (Hardware)
