#  Build everything for LANCELOT A
#
#  version for Unix systems using gfortran

#  Nick Gould, August 8th, 2019, for CGT Productions.

#  Basic system commands

RM=rm -f
CP=cp
MV=mv
SED=sed
CHMOD=chmod

#  Temporary directory for compilation
#  ( do NOT use TMP = . which would cause file overwriting)

TMP=/tmp

#  Default sizing program

SIZE=large

#  Default precision

PRECISION=double

#  Compiler flags (machine dependent)

FORTRAN=gfortran
FFLAGS= -O3 -ffixed-form

#  The installation

lancelot:
	echo "FORTRAN=" $(FORTRAN)
	echo " FFLAGS=" $(FFLAGS)
