Hi All,
My code needs to link to an external C++ library (CGAL). The code is
written in Fortran and I have already written interface to let Fortran
call C++ function. For the sequential version without PETSc, it can be
compiled without problem using the following makefile. The parallel
version without CGAL can also be compiled successfully. However, when I
tried to use PETSc together with CGAL library, I cannot compile the
code. My questions is: How can I modify the makefile? Do I need to
reconfigure PETSc with special flags? All the makefile samples are shown
below.
#makefile for sequential version
FC = gfortran
#FC = ifort
