# !!! This makefile accepts environmental variables CFLAGS, FFLAGS, CPPFLAGS, LDFLAGS, and LDLIBS. First three are
# passed to C, Fortran, and C++ compiler respectively, and last two are passed to the linker. Values specified below are
# added to the values given by the environment. This can be used in invocation of make as: 
# > export CFLAGS=...; make ...
# These variables can also be given in the command line to make, but it will override all values specified in this
# Makefile. This is especially critical for CFLAGS which should be overridden only with much care, including all
# relevant flags in the new value. Moreover, all other variables can be overridden by command line option to make. In
# particular, this can be relevant for specifying a different version of the compiler (see below).

# ---Optional flags---
# Uncomment those that you find appropriate; additional information is in specified headers. One can also export
# environmental variable OPTIONS before executing make, or define its value in the command line of make. For instance,
# 'make OPTIONS=DEBUG ...' or 'make OPTIONS+=DEBUG ...'. If several options need to be given, they should be given as
# one argument in quotes with its parts separated by spaces, e.g. 'make OPTIONS="DEBUG FFT_TEMPERTON" ...'. OPTIONS that
# are uncommented below are appended to the list specified elsewhere. Full list of possible options is the following:
VALID_OPTS := DEBUG DEBUGFULL FFT_TEMPERTON PRECISE_TIMING NOT_USE_LOCK ONLY_LOCKFILE NO_FORTRAN NO_CPP \
              OVERRIDE_STDC_TEST OCL_READ_SOURCE_RUNTIME CLFFT_APPLE SPARSE USE_SSE3 OCL_BLAS NO_GITHASH HOMEBREW \

# Debug mode. By default, release configuration is used (no debug, no warnings, maximum optimization). DEBUG turns on
# producing debugging symbols (-g) and warnings and brings optimization down to O1. DEBUGFULL turns off optimization 
# completely and turns on additional diagnostic messages in the source code (debug.c/h).
#override OPTIONS += DEBUG
#override OPTIONS += DEBUGFULL

# Not clear if that is beneficial
#OPTIONS += USE_SSE3

# Temperton FFT (fft.h).
#override OPTIONS += FFT_TEMPERTON

# Precise timing (prec_timing.h).
#override OPTIONS += PRECISE_TIMING

# Controls the mode of file locking, if any (io.h). Use at maximum one of the following options.
#override OPTIONS += NOT_USE_LOCK
#override OPTIONS += ONLY_LOCKFILE

# This should be uncommented, if compiling of Fortran sources cause problems. However, currently a number of ADDA
# (optional) features rely on Fortran sources, in particular: IGT, Temperton FFT. This features will not work if line
# below is uncommented.
#override OPTIONS += NO_FORTRAN

# This should be uncommented, if compiling of C++ sources cause problems. However, currently a number of ADDA (optional)
# features rely on C++ sources, in particular: OpenCL version. This features will not work if line below is uncommented.
#override OPTIONS += NO_CPP

# ADDA code relies on certain parts of C99 standard, therefore support of this standard is checked at compile time (and
# error is produced if the test fails). However, if you believe that your compiler supports all the required features
# (listed in const.h), but do not define itself conforming to C99, you may uncomment the following option to override
# the test. Do it at your own risk!
#override OPTIONS += OVERRIDE_STDC_TEST

# By default OpenCL version of ADDA reads CL kernel source from file(s) *.cl during compilation and stores them as
# static string, which is compiled into the GPU code at runtime. Alternative option is to read these files at runtime.
# This creates hassle of keeping .cl files together with the executable, but may be a bit more robust/portable than
# the default approach. Uncomment the following option to enable reading of kernel sources at runtime.
#override OPTIONS += OCL_READ_SOURCE_RUNTIME

# APPLE clFFT (fft.h)
#override OPTIONS += CLFFT_APPLE

# Uses clBLAS library for iterative solver (currently, only in BiCG, no effect on the other methods)
#override OPTIONS += OCL_BLAS

# By default, this Makefile invokes a Bash script that will determine the current subversion revision and pass it to
# ADDA source (so it is produced in the output of 'adda -V'. If this causes any problems (including significant delays),
# the functionality can be disabled by uncommenting the following line.
#override OPTIONS += NO_GITHASH

# Adds paths to libraries and headers of packages installed by Homebrew (if it is not done system-wide by Homebrew
# itself). Assumes that $(HOMEBREW_PREFIX) is provided by the system
#override OPTIONS += HOMEBREW

# ---Compilers---
# Choose one of the following. Can also be specified from command line to make (see explanation above for OPTIONS),
# overriding definition below. To specify a different version of the compiler, e.g. 'gcc-4.7' instead of 'gcc', use
# command 'make CC=gcc-4.7' (analogously for Fortran and C++ compilers).
# gnu - tested for multiple versions starting from 3.2.3, but recently only 4.8 and higher
# intel (Intel C++ and Fortran Compilers Classic) - tested for versions starting from 9.0, but recently only on 2021.1
# intelX (Intel oneAPI C++ Compiler, based on LLVM, and new Fortran compiler) - tested on version 2021.1 
# compaq - tested on Compaq C V6.5-303 (dtk) - last tested in 2007
# ibm - tested on xlc 8.0 - last tested in 2008
# hpux - tested on ia64

# Additional options for compiler. Flags specified below are appended to the ones specified in the environment or
# command line of make (see explanation above for OPTIONS). The same value is used for all programming languages to be
# compiled and for linker. In particular, "-m32" may be used to force 32 bit compilation in 64 bit environment. However,

# may be required to specify paths manually (last 2 lines). Relative (to location of this Makefile) paths should be
