# If we are using f2c there will be a command for the `%.c : %.f'
# pattern and no command for the `%.o : %.f' pattern, so that make
# will not invoke the fortran compiler by mistake.
#
# If we are not using f2c, it should be ok to have an empty rule for
# the pattern `%.c : %.f', but we don't want to replace make's default
# rule for making object from Fortran source files, so there should be
# no pattern or command for that.

# How to make .o files:

%.o : %.c
	$(CC) -c $(CPPFLAGS) $(ALL_CFLAGS) $<

%.o : %.cc
	$(CXX) -c $(CPPFLAGS) $(ALL_CXXFLAGS) $<

pic/%.o : %.c
	$(CC) -c $(CPPFLAGS) $(CPICFLAG) $(ALL_CFLAGS) $< -o $@

pic/%.o : %.cc
	$(CXX) -c $(CPPFLAGS) $(CXXPICFLAG) $(ALL_CXXFLAGS) $< -o $@

# Here is a rule for generating dependencies for .cc files:

%.d : %.cc
	@echo making $@ from $<
	@rm -f $@
	@$(CXX) -M $(CPPFLAGS) $(ALL_CXXFLAGS) $< | \
	  sed -e 's,$*\.o,pic/& & $@,g' > $@.tmp
	@mv $@.tmp $@

# And one for .c files.too:

%.d : %.c
	@echo making $@ from $<
	@rm -f $@
	@$(CC) -M $(CPPFLAGS) $(ALL_CFLAGS) $< | \
	  sed -e 's,$*\.o,pic/& & $@,g' > $@.tmp
