Conda nRF5

Introduction

This simple repository shows how to setup Conda enviroment for building nrf5 projects. The main inspiration for this repository was a great blog on a great blog Interrupt: https://interrupt.memfault.com/blog/conda-developer-environments

Setup

# Download for Linux:
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
# install it
bash Miniconda3-latest-*-x86_64.sh
# Restart shell or open a new Tmux pane
# Disable conda activating at startup
conda config --set auto_activate_base false

Quick start

Open terminal from the root of the project which uses Conda as a package manager, aka. has environment.yaml in its root.

# Create new enviroment
conda create -n <env_name>

# To activate it, shell alias is preferred
conda activate <env_name>

# To update environment according to a yml file
conda env update -f environment.yml

Usage

# Create new environment
conda create -n <env_name>

# To activate it, shell alias is preferred
conda activate <env_name>

# To deactivate it, shell alias is also preferred
conda deactivate

# To remove it
conda env remove -n <env_name>

# To update environment according to a yml file
conda env update -f environment.yml

Configuration

Create a environment.yml file with required packages (look inside this repo for an example) and then run: conda env update -f environment.yml.

Building packages

Look into conda_recipes for some inspiration on how to build a conda package. After you created required meta.yml and build.sh you can create a build environment to build them and then upload them.

conda create -n build
conda activate build
conda install -c conda-forge conda-build anaconda-client python=3.7 nlohmann_json protobuf grpc-cpp fmt spdlog pkg-config
conda install -c markosagadin abseil-cpp
conda build .
# Build command will give you a suggestion for upload
anaconda upload ...

Lower version of Python is required, due to the error module 'base64' has no attribute 'encodestring' inside anaconda-client program.

Creating sha256sum

I have no idea how to do this properly. You can first set random sha in meta.yaml and then run conda build ., which will tell you the actual sha, you can just copy it from there.

Troubleshooting building packages

Command anaconda upload can fail silently due to many reasons, there is an issue on GitHub (Anaconda-Platform/anaconda-client#501), where you can find a snipppet of code that you need to paste to a binstar_client/commands/upload.py in order to see the actual error.

Errors could be:

Expired authorization token
Large file
Above error with module base64
And others.

If the last line of the anaconda upload command is Uploading file ".. and nothing else then the error happened.
