### User Configurable Options

## To set up, follow the steps [1], [2], [3], [4] below

###################################
## [1]
## Set equal to yes if your compiler supports C++11.
## (Also make sure to add a flag like -std=c++11 to the CCCOM variable below.)
USE_CPP11=no
###################################

#########
## [2]
##
## Set which compiler to use by defining CCCOM:
##GNU GCC compiler, consider adding flag -std=c++11 to enable newer C++11 features
CCCOM=g++ -m64 #-std=c++11
##Clang compiler (good to use on Mac OS), consider adding flag -std=c++1y to enable newer C++14 features
#CCCOM=clang++ #-std=c++1y
##Intel C++ compiler (good to use with Intel MKL if available), consider adding -std=c++11
#CCCOM=icpc #-std=c++11
#########

## [3]
##
## BLAS/LAPACK Related Options
##
## o The variable PLATFORM can be set to macos,lapack,mkl, or acml.
##   This tells ITensor which style of BLAS/Lapack library to expect.
##
## o BLAS_LAPACK_LIBFLAGS should be something like
##   -L/path/to/lapack/lib -llapack -lblas
##   though the names of the static libraries (the files referred
##   to by the -l flags) can be highly variable - see examples below.
##
## o BLAS_LAPACK_INCLUDEFLAGS is currently required for the mkl platform only.
##   It should be set to -I/path/to/lapack/include
##   where "include" is a folder full of .h header files in the source code
##   of your BLAS/Lapack library (see examples below).
##

##
## Mac OSX system
##

PLATFORM=macos
BLAS_LAPACK_LIBFLAGS=-framework Accelerate

##
## Example using a C interface to LAPACK on GNU/LINUX systems
##

#PLATFORM=lapack
#BLAS_LAPACK_LIBFLAGS=-L/usr/lib -lblas -llapack

##
## Example using the Intel MKL library
##

#PLATFORM=mkl
## MKL example (recommended with Intel C++ compiler icpc for performance on Intel CPUs)
#BLAS_LAPACK_LIBFLAGS=-L/opt/intel/composer_xe_2013_sp1.1.106/mkl/lib/intel64 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_rt -lmkl_core -liomp5 -lpthread
#BLAS_LAPACK_INCLUDEFLAGS=-I/opt/intel/composer_xe_2013_sp1.1.106/mkl/include

##
## Example using the AMD ACML library
##

#PLATFORM=acml
#BLAS_LAPACK_LIBFLAGS=-L/opt/acml5.1.0/gfortran64/lib -lacml -lgfortran -lpthread


#########
## [4]
##
## This step is optional, but if you wish to customize the flags
## used to compile optimized and debug code, you can do so here.

## Flags to give the compiler for "release mode"
OPTIMIZATIONS=-O2 -DNDEBUG -Wall

## Flags to give the compiler for "debug mode"
DEBUGFLAGS=-DDEBUG -DMATRIXBOUNDS -DITENSOR_USE_AT -DBOUNDS -g -Wall


###
### Other Makefile variables defined for convenience.
### Not necessary to modify these for most cases.

## Use this variable to set the location of the boost
## headers on your machine (this folder should have another one called 'boost' inside it).
## If USE_CPP11=yes, this variable will not be used.
