# These instructions are for installing a conda environment for CODAS on an
# Apple computer with an ARM chip.  They have been tested M1-M4 machines.
# The non-standard aspect arises from slightly different code collections
# for Intel vs ARM.

# If you have not already done so, install the command-line compiler tools:
xcode-select --install
# You can check this with
gcc --version
# which will print several lines of info if the compiler is installed.

# Install miniconda:
# 1) In any directory, download it:
curl -LO https://repo.anaconda.com/miniconda/Miniconda3-latest-MacOSX-arm64.sh

# 2) and install it.
bash Miniconda3-latest-MacOSX-arm64.sh

#   Accept the license and the default location, but answer "no" to the
#   question about initialization.

# Now, back at the prompt, execute the initialization:
~/miniconda3/bin/conda init --all

# Quit the terminal *application* (not just the window) and open a new
# terminal.
# Configure conda:
conda config --set auto_activate_base false
conda config --add channels conda-forge
conda config --set channel_priority strict

# Again, quit the terminal application, and open a new terminal.
# Make the new environment:
conda env create --file codas_processing_apple.yml

# and activate it:
conda activate pycodas
