## Use fft routines from mathematical t3e libraries
# CPPFLAGS     = -I../include -D__T3E -D__PARA -D__MPI

## Use precompiled fftw library (version <= 2.1.5, NOT v.3!)
## In this case, specify also how to load the fftw library (FFTW_LIB)
## and the path to the fftw.h include file (FFTW_INC_DIR). Example:
# FFTW_LIB     = -L/usr/local/src/fftw-2.1.3/fftw/.libs -lfftw
# FFTW_INC_DIR = /usr/local/src/fftw-2.1.3/fftw
# CPPFLAGS     = -D__T3E -D__PARA  -D__MPI -D__FFTW -I../include \
#                -I$(FFTW_INC_DIR)

# Use the local copy of fftw
CPPFLAGS     = -D__T3E -D__PARA  -D__MPI -D__FFTW -D__USE_INTERNAL_FFTW \
