##===========================================================
## Minimal Makefile for Fortran parts of KronLinInv
##
## Note that Julia and Python have their own "pure" implementation of the algorithm,
## which doesn't need any compilation. The respective Fortran wrappers are optional,
## for speed.
##
## It is possible to compile single versions of the program or all together:
##
## * sharedmemfortran: compile the serial/shared memory Fortran code
## * distribmemfortran: compile the OpenMPI/distributed memory Fortran code
## * wrapforjulia: compile Fortran wrappers for Julia
## * wrapforpython: compile Fortran wrappers for Python
## * all: compile all Fortran code and wrappers for Julia and Python
##
## Example:
## make distribmemfortran
## will compile the OpenMPI distributed memory version of KronLinInv
## make all
## will compile all Fortran files
##
## MPI Fortran compiler
MPIFC = mpifort
## Fortran compiler
FC = gfortran
## Output dir for Fortran executables
OUTDIR = examples/
## Shared memory parallelism, set to nothing if OpenMP is not available
OMP = -fopenmp
## options for gfortran, may differ for other compilers
OPTFOR = -std=f2008 -O3 -funroll-loops -llapack -lblas
## DEBUG
##OPTFOR = -std=f2008 -g -fcheck=all -fbounds-check -Wrealloc-lhs-all -llapack -lblas
## include/linking for HDF5 libraries, system-depent
LIBSHDF = -I/usr/include/hdf5/serial -L/usr/lib/x86_64-linux-gnu/hdf5/serial
