# Configure compiler flags for the current machine
# By default, we simply build with the highest instruction set available on the current machine
# if you want to use a different instruction set, you can set this in the CXX_FLAGS, CUDA_FLAGS, C_FLAGS,
# e.g. 
#   export CXX_FLAGS="-march=core-avx2 -fPIC"
#   export C_FLAGS="-march=core-avx2 -fPIC"
#   export CUDA_FLAGS="-arch=sm_35"
export CXX_FLAGS="-march=native -fPIC"
export C_FLAGS="-march=native -fPIC"
export CUDA_FLAGS="-arch=native"

# Configure linker flags for the current machine. By default, we use the gold linker
export EXE_LINKER_FLAGS="-fuse-ld=gold"

# If we detect that we are on a Mac, we need to set the OpenMP_ROOT variable to the correct path
if [[ "$OSTYPE" =~ ^darwin ]]; then
    export OpenMP_ROOT=$(brew --prefix)/opt/libomp
    # On Mac, we use the clang linker by default. If you want to use the gold linker, you can set this here
    export EXE_LINKER_FLAGS=""
fi

# Also, the name of the python executable may vary for your system. You can set this here
pythoncmd=python3
