#!/bin/bash
Build scripts by default are run from the build directory. This command will change directories to the location of the build script which is useful for this library.
cd "$(dirname "$0")"
# turn on verbose debugging output for parabuild logs. set -x # make errors fatal set -e ZLIB_VERSION="1.2.5" ZLIB_SOURCE_DIR="zlib-$ZLIB_VERSION"
The autobuild command should be passed as an environment variable.
if [ -z "$AUTOBUILD" ] ; then fail fi
On windows systems, the path contained in the AUTOBUILD environment variable
if [ "$OSTYPE" = "cygwin" ] ; then export AUTOBUILD="$(cygpath -u $AUTOBUILD)" fi
The autobuild source_environment command returns a string with shell code. This code contains some useful functions that we will use later in the build process.
