Visit CASA.md for instructions on installing CASA in an Anaconda Python environment.
This repository contains the tools I use to build various packages in the
Conda package manager used by the Anaconda Python distribution. Most of
them build up to providing support for the Gtk+ 3 graphical toolkit and the
CASA radio interferometry package. Builds are provided on 64-bit Linux and
OS X. My packages are layered on top of those provided by the conda-forge
project, so you must add conda-forge as a channel in your Conda
configuration!
I upload built packages to my personal anaconda.org channel. You can configure your Anaconda installation to fetch packages from it with:
conda config --add channels pkgw-forge
To directly install the package pwkit (for example) without altering your
configuration, use:
conda install -c pkgw-forge pwkit
As part of this work I’ve also developed a prebuilt Docker image that can be
used to repeatably build binary linux-64 packages. For OS X, I use Vagrant
to make osx-64 packages repeatably. My notes for developers may be
valuable if you’re interesting in making Conda packages containing compiled
code for Linux and/or Mac OS X machines.
Many of my Conda packages involve compiled code, and a big challenge is building such packages in a way that’s as platform-independent as possible. The OS X developer tools make this fairly manageable. But Linux is harder, especially since Conda doesn't explicitly specify the ABIs that they target. However, things built on CentOS 5 are generally highly portable — but no one wants to run CentOS 5 as their primary OS since it’s ancient!
So there are two main components to how I build my Conda packages. First, I have set up a Docker environment that allows me to build packages repeatably inside a stable, containerized Centos 5 environment. Then, I’ve written the Conda recipes that actually define the packages that I build. I’ve written up notes on how the system works if you might be interested in doing similar things.
OK, there are three components — I use Vagrant to generate and drive a repeatable, headless build environment for the OS X package builds.
