========================================================================

This main.scons file is the root description of the build specified in this

directory and those under it. Individual components and the source files

used to build them are described in subsidiary files called 'build.scons'.

#

To build this project change the current directory to googleclient/Omaha.

Then run hammer.bat

#

A number of command line options can be specified. For a full list, use the

-h and -H command options.

#

Some useful options include:

-h : Prints a list of which modules and build variants are available

in this project.

-H : Print SCons specific help. SCons is a build tool which this

project uses in tandem with the Software Construction Toolkit

to build.

-c : Clean the project. I.e. delete all build output.

-j3 : Run up to 3 build steps at once.

#

Some useful build targets include:

all_programs : Build all programs generated by this project.

all_libraries : Build all libraries generated by this project.

all_tests : Build all tests generated by this project.

run_all_tests : Build and run all tests generated by this project.

#

Some examples:

Build all programs and libraries in debug mode:

hammer

Build and run all tests in debug mode on windows:

hammer MODE=dbg-win run_all_tests

Build arbitrary library in the default mode:

hammer

import os

To switch the build, simply change the value of the msc_ver variable below.

VC2003/VC71 is 1310 but not supported by the current build.

VC2005/VC80 is 1400.

VC2008/VC90 is 1500.

_msc_ver = 1400

TODO(Omaha) - Change this to match the official product name

_PUBLISHER_NAME = 'Google' _PRODUCT_NAME = 'Update' _ACTIVEX_NAME = 'npGoogleOneClick' _BHO_NAME = 'GoopdateBho'

The hash comes from the Thumbprint item in the Details tab of the file

properties for the public key .cer file.

TODO(omaha): Can we automate reading this and/or pass it on the command line?

COM proxy setting.

The proxy clsid needs to be changed anytime the interfaces in

google_update_idl.idl change, or when a new interface is added. Use

guidgen.exe to generate new clsids in the format 'static const struct GUID'.

The precompiled headers are to be used as an optional build speed up

build facility. Individual compilation units in the project must build with

or without precompiled headers. Building without precompiled headers is sort

of meaningless, since all the time we should build with it. However,

eliminating the dependency is desirable from a few reasons:

1. making sure the files in the project include all the definitions they need

2. creating different precompile headers if needed.

3. making sure the precompile headers do not add to the size bloat.

There are two current limitations with the current setup.

First, due to pushing the warning level to W4 and WAll, we rely on the

common precompile.h to properly turn off the warnings inside system and

library code.

Second, to override the ATLASSERT, a file must be included before any of

the atl headers. To do this on a case by case basis is impractical and

error prone.

Therefore, when building with precompile headers off, the code is

building on W3 and it is not taking over the ATL asserts.

Introduction

Omaha, otherwise known as Google Update, is a program to install requested software and keep it up to date. So far, Omaha supports many Google products for Windows, including Google Chrome and Google Earth, but there is no reason for it to only support Google products.

We know that keeping software updated is both important and hard, and so by open-sourcing this project, our hope is that perhaps we can help others solve this problem. So, if you'd like to get involved, or even use Omaha to support your own software projects, then just follow the instructions in the Getting Started guide below, and you'll be good to go!
