# Name: build_shar.sh
|
|
# Requires: python-virtualenv, gcc, gcc-c++, swig, sharutils, and the
|
|
# develepment headers for both python and openssl
|
|
#
|
|
# This script will use GNU sharutils to build an installable shar archive, with
|
|
# an install prefix of "/opt" (unless overridden with the '-p' option). This
|
|
# has a couple uses:
|
|
#
|
|
# 1. Installing salt (by su'ing to root and running "sh /path/to/sharfile")
|
|
# 2. To be used as a basis for creating your own salt rpm/deb.
|
|
#
|
|
# It will fetch libzmq and build it as a pyzmq extension.
|
|
#
|
|
# IMPORTANT: Unpacking the shar requires uudecode, which is distributed along
|
|
# with sharutils. Thus, you should have sharutils installed on any host which
|
|
# will need to unpack the shar archive.
|
|
#
|
|
# The script is capable of building a shar archive using several methods:
|
|
#
|
|
# 1. Using a custom pip requirements file
|
|
# 2. Using an existing salt tarball (downloaded from PyPI)
|
|
# 3. Specifying a version number (the script will fetch the requested version
|
|
# from PyPI)
|
|
#
|
|
# Additionally, it is possible to specify a build_id which will be added to the
|
|
# shar filename, useful for telling apart individual shars.
|
|
#
|
|
# By default, the script will download dependencies using pip, but the '-d'
|
|
# option can be used to specify directory from which dependencies will be
|
|
# sourced. Any missing dependencies will be retrieved with pip.
|
|
#
|
|
# It is strongly recommended to run this script on a machine which does not
|
|
# have any of the Salt dependencies already installed, because if the script
|
|
# detects that ZeroMQ is already installed, then pyzmq's setup.py will not
|
|
# build a bundled ZeroMQ.
|
|
#
|
|
# Run the script with -h for usage details.
