[petsc-users] compiling code that uses Petsc and Sundials

[Kharche, Sanjay]

I just tried the makefile trick, I think that will serve my purpose for now.

thanks. Sanjay

1. you can always rebuild PETSc on the "local supercomputer"

Just grab the reconfigure_arch.py script from the current install [to
capture the recommended mpi, blas etc..] - modify it as you need - and
rerun it with your copy of PETSc sources.

Wrt your install of sundials [assuming its built with the same compilers, mpi etc..
the following might work..

Satish

----------
$ cat makefile

MYSUNDIALS_INCLUDE = -I/path/to/my-sundials/include
MYSUNDIALS_LIB     = -L/path/to/my-sundials -sundials_cvode -lsundials_nvecserial -lsundials_nvecparallel

CPPFLAGS     = ${MYSUNDIALS_INCLUDE}
CLEANFILES   = *.dat *.vtk *.vts ex15 *.o sk2d *~

include ${PETSC_DIR}/conf/variables
include ${PETSC_DIR}/conf/rules

sk2d: sk2d.o  chkopts
      -${CLINKER} -o sk2d sk2d.o  ${PETSC_TS_LIB} ${MYSUNDIALS_LIB} ${BLASLAPACK_LIB} ${MPI_LIB} -lm -inline-calloc

I can see that -lsundials_cvode -lsundials_nvecserial -lsundials_nvecparallel are all there, as well as the blas lapack. Pasted below is my simple makefile and what happens when I make sk2d

This copy of petsc was not installed by connecting to Sundials. Therefore, I have installed sundials in my home directory. I tried to add the sundials paths in the makefile below at various locations (in fact, I could not work out where exactly to put the includes and libs!), but I could not get my code to compile. Any suggestions?
