--- Comment #26 from Jürgen Reuter <juergen.reuter at desy dot de> --- (In reply to anlauf from comment #25) > Unfortunately, there is no main.f90, which is needed to build whizard. > Indeed, sorry, cf. below > The Makefile needs to be modified to take into account that pythia.f > needs preprocessing, e.g.: > > %.o: %.f > $(FC) $(FCFLAGS) -c $< -cpp > > Furthermore, one needs to compile serially; parallel make does not seem to > be supported. I changed the pythia.f to make the preprocessing unnecessary. > > Can you please provide the missing file?
