Empirical Comparison of SCons and GNU Make

A course work of mine, entitled Empirical Comparison of SCons and GNU Make, is now hosted at the company site of my tutors. Thanks guys!

Automatic make dependencies without sed

I'm currently working with plain GNU Make based projects and - again - I tried to find a nice way to automatically track dependencies and finally found a nice solution when skimming over the g++ manpage. There is a lot of black art flowing around, e.g. this gem is from the GNU Make manual:

%.d: %.c
   @set -e; rm -f $@; \
    $(CC) -M $(CPPFLAGS) $< > $@.$$$$; \
    sed 's,\($*\)\.o[ :]*,\1.o $@ : ,g' < $@.$$$$ > $@; \
    rm -f $@.$$$$

Not for the faint of heart, also the thing done by sed is quite trivial. If all you have to support is gcc (portability is overrated!), there's a much more simple way to achieve the same (and more):

%.o: %.c
   $(CC) -MMD -MP -MT '$*.d' -c $(CFLAGS) $< -o $@
