Wrong compiler for fotran_example.F90

[SpinTensor]

the fortran_example.F90 in the fortran folder has the wrong compiler in the Makefile.in

fortran_example: fortran_example.o libint_f.o
        $(LTLINK) $(CXX) $(CXXFLAGS) $(LDFLAGS) $(COMPUTE_LIB) $(SYSLIBS) $(FCLIBS) -o $@ $^

Some compilers cannot use the c++ compiler for this. One manually needs to change it every time.

@SpinTensor thanks for reporting this ... is the issue that $(FCLIBS) incomplete or that the fortran and c++ compilers are configured to use different linkers? There is no good reason why a C++ compiler would not be able to link in fortran runtime libs (FCLIBS is defined for this purpose ... perhaps its computation is broken).

Not every compiler suite works like this. In some the fortran compiler is the most universal one and is used to link c++ code with the appropriate flags.
