This file contains detailed but generic information on building and
installing the C++ part of this project. For shorter instructions,
as well as instructions for compiling and installing the Java or
Python parts, see README.
======================================================================
Copyright 1994, 1995, 1996, 1999, 2000, 2001, 2002 Free Software
Foundation, Inc.
This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.
Basic Installation
==================
These are generic installation instructions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. (Caching is
disabled by default to prevent problems with accidental use of stale
cache files.)
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You only need
`configure.ac' if you want to change it or regenerate `configure' using
a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. Run `./configure --help'
for details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not support the `VPATH'
variable, you have to compile the package for one architecture at a
time in the source code directory. After you have installed the
package for one architecture, use `make distclean' before reconfiguring
for another architecture.
Installation Names
==================
By default, `make install' will install the package's files in
`/usr/local/bin', `/usr/local/man', etc. You can specify an
installation prefix other than `/usr/local' by giving `configure' the
option `--prefix=PATH'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
give `configure' the option `--exec-prefix=PATH', the package will use
PATH as the prefix for installing programs and libraries.
Documentation and other data files will still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=PATH' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' cannot figure out
automatically, but needs to determine by the type of machine the package
will run on. Usually, assuming the package is built to be run on the
_same_ architectures, `configure' can figure that out, but if it prints
a message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the `--target=TYPE' option to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
will cause the specified gcc to be used as the C compiler (unless it is
overridden in the site shell script).
`configure' Invocation
======================
`configure' recognizes the following options to control how it
operates.
`--help'
`-h'
Print a summary of the options to `configure', and exit.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

Protocol Buffers - Google's data interchange format
Copyright 2008 Google Inc.
http://code.google.com/apis/protocolbuffers/
BETA WARNING
============
This package is a beta. This means that API may change in an
incompatible way in the future. It's unlikely that any big changes
will be made, but we can make no promises. Expect a non-beta release
sometime in August 2008.
C++ Installation - Unix
=======================
To build and install the C++ Protocol Buffer runtime and the Protocol
Buffer compiler (protoc) execute the following:
$ ./configure
$ make
$ make check
$ make install
If "make check" fails, you can still install, but it is likely that
some features of this library will not work correctly on your system.
Proceed at your own risk.
"make install" may require superuser privileges.
For advanced usage information on configure and make, see INSTALL.txt.
** Hint on insall location **
By default, the package will be installed to /usr/local. However,
on many platforms, /usr/local/lib is not part of LD_LIBRARY_PATH.
You can add it, but it may be easier to just install to /usr
instead. To do this, invoke configure as follows:
./configure --prefix=/usr
If you already built the package with a different prefix, make sure
to run "make clean" before building again.
** Note for Solaris users **
Solaris 10 x86 has a bug that will make linking fail, complaining
about libstdc++.la being invalid. We have included a work-around
in this package. To use the work-around, run configure as follows:
./configure LDFLAGS=-L$PWD/src/solaris
See src/solaris/libstdc++.la for more info on this bug.
C++ Installation - Windows
==========================
If you are using Micosoft Visual C++, see vsprojects/readme.txt.
If you are using Cygwin or MinGW, follow the Unix installation
instructions, above.
Java and Python Installation
============================
The Java and Python runtime libraries for Protocol Buffers are located
in the java and python directories. See the README file in each
directory for more information on how to compile and install them.
Note that both of them require you to first install the Protocol
Buffer compiler (protoc), which is part of the C++ package.
Usage
=====
The complete documentation for Protocol Buffers is available via the
web at:
http://code.google.com/apis/protocolbuffers/

This directory contains example code that uses Protocol Buffers to manage an
address book. Two programs are provided, each with three different
implementations, one written in each of C++, Java, and Python. The add_person
example adds a new person to an address book, prompting the user to input
the person's information. The list_people example lists people already in the
address book. The examples use the exact same format in all three languages,
so you can, for example, use add_person_java to create an address book and then
use list_people_python to read it.
You must install the protobuf package before you can build these.
To build all the examples (on a unix-like system), simply run "make". This
creates the following executable files in the current directory:
add_person_cpp list_people_cpp
add_person_java list_people_java
add_person_python list_people_python
If you only want to compile examples in one language, use "make cpp",
"make java", or "make python".
All of these programs simply take an address book file as their parameter.
The add_person programs will create the file if it doesn't already exist.
These examples are part of the Protocol Buffers tutorial, located at:
http://code.google.com/apis/protocolbuffers/docs/tutorials.html

Protocol Buffers - Google's data interchange format
Copyright 2008 Google Inc.
This directory contains the Java Protocol Buffers runtime library.
Installation - With Maven
=========================
The Protocol Buffers build is managed using Maven. If you would
rather build without Maven, see the next section.
1) Install Apache Maven if you don't have it:
http://maven.apache.org/
2) Build the C++ code, or obtain a binary distribution of protoc. If
you install a binary distribution, make sure that it is the same
version as this package. If in doubt, run:
$ protoc --version
You will need to place the protoc executable in ../src. (If you
built it yourself, it should already be there.)
3) Run the tests:
$ mvn test
If some tests fail, this library may not work correctly on your
system. Continue at your own risk.
4) Install the library into your Maven repository:
$ mvn install
5) If you do not use Maven to manage your own build, you can build a
.jar file to use:
$ mvn package
The .jar will be placed in the "target" directory.
Installation - Without Maven
============================
If you would rather not install Maven to build the library, you may
follow these instructions instead. Note that these instructions skip
running unit tests.
1) Build the C++ code, or obtain a binary distribution of protoc. If
you install a binary distribution, make sure that it is the same
version as this package. If in doubt, run:
$ protoc --version
If you built the C++ code without installing, the compiler binary
should be located in ../src.
2) Invoke protoc to build DescriptorProtos.java:
$ protoc --java_out=src/main/java -I../src \
../src/google/protobuf/descriptor.proto
3) Compile the code in src/main/java using whatever means you prefer.
4) Install the classes wherever you prefer.
Usage
=====
The complete documentation for Protocol Buffers is available via the
web at:
http://code.google.com/apis/protocolbuffers/

/**
* A table of known extensions, searchable by name or field number. When
* parsing a protocol message that might have extensions, you must provide
* an {@code ExtensionRegistry} in which you have registered any extensions
* that you want to be able to parse. Otherwise, those extensions will just
* be treated like unknown fields.
*
* <p>For example, if you had the {@code .proto} file:
*
* <pre>
* option java_class = "MyProto";
*
* message Foo {
* extensions 1000 to max;
* }
*
* extend Foo {
* optional int32 bar;
* }
* </pre>
*
* Then you might write code like:
*
* <pre>
* ExtensionRegistry registry = ExtensionRegistry.newInstance();
* registry.add(MyProto.bar);
* MyProto.Foo message = MyProto.Foo.parseFrom(input, registry);
* </pre>
*
* <p>Background:
*
* <p>You might wonder why this is necessary. Two alternatives might come to
* mind. First, you might imagine a system where generated extensions are
* automatically registered when their containing classes are loaded. This
* is a popular technique, but is bad design; among other things, it creates a
* situation where behavior can change depending on what classes happen to be
* loaded. It also introduces a security vulnerability, because an
* unprivileged class could cause its code to be called unexpectedly from a
* privileged class by registering itself as an extension of the right type.
*
* <p>Another option you might consider is lazy parsing: do not parse an
* extension until it is first requested, at which point the caller must
* provide a type to use. This introduces a different set of problems. First,
* it would require a mutex lock any time an extension was accessed, which
* would be slow. Second, corrupt data would not be detected until first
* access, at which point it would be much harder to deal with it. Third, it
* could violate the expectation that message objects are immutable, since the
* type provided could be any arbitrary message class. An unpriviledged user
* could take advantage of this to inject a mutable object into a message
* belonging to priviledged code and create mischief.

dnl @summary figure out how to build C programs using POSIX threads
dnl
dnl This macro figures out how to build C programs using POSIX threads.
dnl It sets the PTHREAD_LIBS output variable to the threads library and
dnl linker flags, and the PTHREAD_CFLAGS output variable to any special
dnl C compiler flags that are needed. (The user can also force certain
dnl compiler flags/libs to be tested by setting these environment
dnl variables.)
dnl
dnl Also sets PTHREAD_CC to any special C compiler that is needed for
dnl multi-threaded programs (defaults to the value of CC otherwise).
dnl (This is necessary on AIX to use the special cc_r compiler alias.)
dnl
dnl NOTE: You are assumed to not only compile your program with these
dnl flags, but also link it with them as well. e.g. you should link
dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
dnl $LIBS
dnl
dnl If you are only building threads programs, you may wish to use
dnl these variables in your default LIBS, CFLAGS, and CC:
dnl
dnl LIBS="$PTHREAD_LIBS $LIBS"
dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
dnl CC="$PTHREAD_CC"
dnl
dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
dnl
dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
dnl default action will define HAVE_PTHREAD.
dnl
dnl Please let the authors know if this macro fails on any platform, or
dnl if you have any other suggestions or comments. This macro was based
dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with
dnl help from M. Frigo), as well as ac_pthread and hb_pthread macros
dnl posted by Alejandro Forero Cuervo to the autoconf macro repository.
dnl We are also grateful for the helpful feedback of numerous users.

# -mthreads: Mingw32/gcc, Lynx/gcc
# -mt: Sun Workshop C (may only link SunOS threads [-lthread], but it

Protocol Buffers - Google's data interchange format
Copyright 2008 Google Inc.
This directory contains the Python Protocol Buffers runtime library.
Normally, this directory comes as part of the protobuf package, available
from:
http://code.google.com/p/protobuf
The complete package includes the C++ source code, which includes the
Protocol Compiler (protoc). If you downloaded this package from PyPI
or some other Python-specific source, you may have received only the
Python part of the code. In this case, you will need to obtain the
Protocol Compiler from some other source before you can use this
package.
Installation
============
1) Make sure you have Python 2.4 or newer. If in doubt, run:
$ python -V
2) If you do not have setuptools installed, note that it will be
downloaded and installed automatically as soon as you run setup.py.
If you would rather install it manually, you may do so by following
the instructions on this page:
http://peak.telecommunity.com/DevCenter/EasyInstall#installation-instructions
3) Build the C++ code, or install a binary distribution of protoc. If
you install a binary distribution, make sure that it is the same
version as this package. If in doubt, run:
$ protoc --version
4) Run the tests:
$ python setup.py test
If some tests fail, this library may not work correctly on your
system. Continue at your own risk.
Please note that there is a known problem with some versions of
Python on Cygwin which causes the tests to fail after printing the
error: "sem_init: Resource temporarily unavailable". This appears
to be a bug either in Cygwin or in Python:
http://www.cygwin.com/ml/cygwin/2005-07/msg01378.html
We do not know if or when it might me fixed. We also do not know
how likely it is that this bug will affect users in practice.

"""Bootstrap setuptools installation
If you want to use setuptools in your package's setup.py, just include this
file in the same directory with it, and add this to the top of your setup.py::
from ez_setup import use_setuptools
use_setuptools()
If you want to require a specific version of setuptools, set a download
mirror, or use an alternate download directory, you can do so by supplying
the appropriate options to ``use_setuptools()``.
This file can also be run as a script to install or upgrade setuptools.

# For reference, if we didn't have to worry about VPATH (i.e., building from
