This is a test to put a pre-packaged carta-backend in an npm package.
It simply uses the
binary-install npm package to download and extract a pre-packaged carta-backend from our Github repository.
At the moment it only supplies a carta-backend (specifically v1.4.0-beta1) for Ubuntu.
binary-install is able to detect the OS and architecture, so later we could easily put packaged carta-backends
of different architectures on our Github repository, and
binary-install would automatically grab the correct one.
After installing, you can find and execute it from here:
It accepts all the normal carta-backend flags; -base, -root, -threads etc.
carta140b1 is a simple shell script containing the following lines:
#!/bin/bash export LD_LIBRARY_PATH=lib:$LD_LIBRARY_PATH export CASAPATH="../../../$PWD/etc linux" bin/carta_backend $@
carta_backend exectuable is in a deeper
bin folder. It is accompanied by a
lib folder containing all the required library files, and an
etc folder containing the necessary CASA ephemerides and geodetic data folders.
carta140b1 shell script is required to make the
carta_backend executable aware of their locations.
This is my first attempt, so I might be able to improve the directory structure later (e.g. if two
bin folders are confusing).
Ultimately, I would hope this could be combined with
carta-node-server to make deployment a lot easier.
It should save a lot of time (and storage space) by eliminating the need to build the carta-backend from source. That process is quite involend needing many pacakges and third party libraries installed/built (e.g. uWS, zfp, carta-casacore, and casacore-data).
