10. Prerequisites and Package Specifications.md

Prerequisites

wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh
bash Miniconda*.sh			    	    		  # install Miniconda to get conda, ensure $PATH is updated in .bashdrc
conda update conda
conda install conda-build conda-verify
conda install anaconda-client					  # optional, only if uploading to Anaconda cloud

Notes

  1. FIELDS disct in https://github.com/conda/conda-build/blob/7164022e81395c6a64a1e529f54f702bd160662c/conda_build/metadata.py contains valid fields in meta.yaml
  2. conda build will create multiple build instance directories in CONDA_PREFIX/conda-bld. These intermediate dirs can be cleaned by conda build purge from the recipe directory.
  3. conda renderin the recipe directory will render the filled meta.yaml file, with jinja2 subs

90. Unstructured Notes.md

Reference Pointers - should eventually move to above files

Reference 1 Reference 2

  • Explains build vs host vs run for the Requirements sections
  • Explains briefly run_exports, and how the runtime dependencies are implicitly set by host, and by build under certain circumstances

The valid structure of meta.yaml is defined in file metadata.py
