If using PETSc from fortran - why use --with-clanguage=cxx ? Also - verify if PETSc examples work - before attempting your code. And then use PETSc makefiles.
[i.e copy the makefile from PETSc example dir - and modify the target to build your code] Satish On Sat, 16 May 2009, Tahar Amari wrote: > Just to let you know is that I built petsc with c++ anyway since I did > > configure -with-cc=gcc --download-mpich=1 --download-parmetis=1 > --with-#shared=0 --download-f-blas-lapack --with-clanguage=cxx --with-cxx=g++ > --with-fc=ifort --with-dynamic=0 > > > Tahar > > > Le 15 mai 09 ? 23:49, Matthew Knepley a ?crit : > > > On Fri, May 15, 2009 at 4:35 PM, Tahar Amari <amari at > > cpht.polytechnique.fr> > > wrote: > > Thanks , > > > > Now this a different kind of errors (just a piece of those below :) > > > > If you want to use C++, you should configure using --with-clanguage=cxx. > > Then you will get the C++ linker. > > > > Matt > > > > > > gcc -o mh4d mh4d.o petsc.o comm.o setbc.o local.o gridutil.o mympi.o > > terminator.o operator.o shellsort.o edge.o side.o vertex.o tetrahedron.o > > rotation.o tetrahedralgrid.o field.o -I/usr/local/hdf/HDF4.2r1/include > > -L/usr/local/hdf/HDF4.2r1/lib -lmfhdf -ldf -lsz -ljpeg -lz > > -L/usr/local/petsc/macx/lib -lpetscsnes -lpetscvec -lpetscmat -lpetsccontrib > > -lpetscts -lpetscdm -lpetscksp -lpetsc -lmpich -lmpichcxx -lpmpich -lfmpich > > -lmpichf90 -lparmetis -lmetis -lfblas -lflapack -L/usr/X11R6/lib -lX11 -lXt > > -lXext -lX11 -L/usr/local/petsc/macx/lib -lpetscsnes -lpetscvec -lpetscmat > > -lpetsccontrib -lpetscts -lpetscdm -lpetscksp -lpetsc -lmpich -lmpichcxx > > -lpmpich -lfmpich -lmpichf90 -lparmetis -lmetis -lfblas -lflapack > > Undefined symbols: > > "std::basic_ostringstream<char, std::char_traits<char>, std::allocator<char> > > >::basic_ostringstream(std::_Ios_Openmode)", referenced from: > > PetscErrorCxx(int, char const*, char const*, char const*, int, int)in > > libpetsc.a(err.o) > > PETSc::Exception::Exception(std::basic_string<char, > > std::char_traits<char>, std::allocator<char> > const&)in libpetsc.a(err.o) > > "_for_stop_core", referenced from: > > _advmom_cv_ in mh4d.o > > _advmom_cv_ in mh4d.o > > _advmom_cv_ in mh4d.o > > _terminators_mp_terminator_ in terminator.o > > _terminators_mp_terminator_all_ in terminator.o > > _tetrahedralgrid_mod_mp_zero_bndr_tvv_ in tetrahedralgrid.o > > > > > > > > > > Le 15 mai 09 ? 23:29, Matthew Knepley a ?crit : > > > > CLINKER > > > > > > > > > > -- > > What most experimenters take for granted before they begin their experiments > > is infinitely more interesting than any results to which their experiments > > lead. > > -- Norbert Wiener >
