[petsc-users] Makefile for mixed C++ and Fortran code

[Danyang Su]

Follow up:

With following command

executable: $(SOURCES) chkopts
     -${FLINKER} $(FFLAGS) $(FPPFLAGS) $(CPPFLAGS)  -o executable.out 
$(SOURCES) ${PETSC_LIB}

%.o:%.F90
     $(FLINKER) $(FFLAGS) $(FPPFLAGS) -c -frounding-math $< -o $@
%.o:%.cpp
     $(CLINKER) $(CXXFLAGS) $(CPPFLAGS) -c -frounding-math $< -o $@

The compiler return error: no match function.

../../usg/cgal_triangulation_2d.cpp: In function ‘void 
outputTriangulation2d(in\
t, const char*, int, const char*)’:
../../usg/cgal_triangulation_2d.cpp:485:20: error: no matching function 
for cal\
l to ‘std::basic_ofstream<char>::open(std::string&)’
     out.open(strfile);

Thanks,


Danyang
