# Getting started with the Userland Consolidation

## Getting Started

This README provides a very brief overview of the gate, how to retrieve

a copy, and how to build it.  Detailed documentation about the Userland

gate can be found in the 'doc' directory.

## Overview

The Userland consolidation maintains a project at

     https://github.com/oracle/solaris-userland

That repo contains build recipes, patches, IPS manifests, etc. necessary

to download, prep, build, test, package and publish open source software.

The build infrastructure is similar to that of the SFW consolidation in

that it makes use of hierarchical Makefiles which provide dependency and

recipe information for building the components.  In order to build the

contents of the Userland gate, you need to clone it.  Since you are

reading this, you probably already have.

## Getting the Bits

As mentioned, the gate is stored in a Mercurial repository.  In order to

build or develop in the gate, you will need to clone it.  You can do so

with the following command

This will create a replica of the various pieces that are checked into the

source code management system, but it does not retrieve the community

source archives associated with the gate content.  To download the

community source associated with your cloned workspace, you will need to

execute the following:

This will use GNU make and the downloading tool in the gate to walk through

all of the component directories downloading and validating the community

source archives from the gate machine or their canonical source repository.

There are two variation to this that you may find interesting.  First, you

can cause gmake(1) to perform it's work in parallel by adding '-j (jobs)'

to the command line.  Second, if you are only interested in working on a

particular component, you can change directories to that component's

directory and use 'gmake download' from that to only get it's source

archive.

## Building the Bits.

You can build individual components or the contents of the entire gate.

### Component build

If you are only working on a single component, you can just build it using

following:

    $ cd (your-workspace)/components ; gmake setup

    $ cd (component-dir) ; gmake publish

### Complete Top Down build

Complete top down builds are also possible by simply running

The 'publish' target will build each component and publish it to the

workspace IPS repo.

Tools to help facilitate build zone creation will be integrated

shortly.  If the zone you create to build your workspace in does not have

networking enabled, you can pre-download any community source archives into

your workspace from the global with:

- You can add parallelism to your builds by adding '-j (jobs)' to your gmake

  command line arguments.

- The gate should only incrementally build what it needs to based on what has

  changed since you last built it.
