build

#!/bin/sh

# Simple wrapper for conda-build that defines the appropriate tag and date for
# internal Gemini package builds.
#
# (If the local date is liable to change between invoking ./checkout & ./build,
# it can be set in the environment prior to running these scripts, but will
# then need updating when building on different days in a persistent session).

# This whole block just decides whether the build path length must be reduced
# to 70 for building Gemini IRAF (otherwise better to stick to 255, allowing
# installation under longer paths). Although dependencies are expanded out here
# to check for "iraf*", conda-build should decide the right order in which (and
# whether) to build them, so is allowed to resolve them again below, for
# generality. The "--prefix-length" option requires conda-build >= 2.1. This
# would be better implemented per-package, as a meta.yaml option for
# conda-build, or failing that by hooking into its dependency resolution.
