Wed Dec 13 12:37:19 2006 Google Inc. <opensource@google.com>
* google-gflags: initial release:
The gflags package contains a library that implements commandline
flags processing. As such it's a replacement for getopt(). It
has increased flexibility, including built-in support for C++
types like string, and the ability to define flags in the source
file in which they're used.

Installation Instructions
*************************
Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
2006, 2007 Free Software Foundation, Inc.
This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.
Basic Installation
==================
Briefly, the shell commands `./configure; make; make install' should
configure, build, and install this package. The following
more-detailed instructions are generic; see the `README' file for
instructions specific to this package.
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 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.
Running `configure' might take a while. 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.
6. Often, you can also type `make uninstall' to remove the installed
files again.
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=c99 CFLAGS=-g 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 can use 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 `..'.
With a non-GNU `make', it is safer 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' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc. You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' 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 option `--target=TYPE' 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
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script).
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
an Autoconf bug. Until the bug is fixed you can use this workaround:
CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
`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.
INSTALLING A BINARY DISTRIBUTION PACKAGE
========================================
No official binary distribution packages are provided by the gflags developers.
There may, however, be binary packages available for your OS at
https://code.google.com/p/gflags/downloads/list. Please consult also the
package repositories of your Linux distribution.
For example on Debian/Ubuntu Linux, gflags can be installed using the
following command:
$ sudo apt-get install gflags
BUILDING THE SOFTWARE FROM SOURCES
==================================
Build Steps
-----------
The build system of gflags is since version 2.1 based on CMake (cmake.org).
The common steps to build, test, and install software based on CMake are:
1. Extract source files.
2. Create build directory and change to it.
3. Run CMake to configure the build tree.
4. Build the software using selected build tool.
5. Test the built software.
6. Install the built files.
On Unix-like systems with GNU Make as build tool, these build steps can be
summarized by the following sequence of commands executed in a shell,
where $package and $version are shell variables which represent the name
of this package and the obtained version of the software.
$ tar xzf gflags-$version-source.tar.gz
$ cd gflags-$version
$ mkdir build && cd build
$ ccmake ..
- Press 'c' to configure the build system and 'e' to ignore warnings.
- Set CMAKE_INSTALL_PREFIX and other CMake variables and options.
- Continue pressing 'c' until the option 'g' is available.
- Then press 'g' to generate the configuration files for GNU Make.
$ make
$ make test (optional)
$ make install (optional)
In the following, only gflags-specific CMake settings available to
configure the build and installation are documented.
CMake Options
-------------
- CMAKE_INSTALL_PREFIX Installation directory, e.g., "/usr/local" on Unix
and "C:\Program Files\gflags" on Windows.
Advanced CMake Options
----------------------
- GFLAGS_NAMESPACE Name of the C++ namespace to be used by the gflags library.
Note that the public source header files are installed in
a subdirectory named after this namespace. To maintain
backwards compatibility with the Google Commandline Flags,
set this variable to "google". The default is "gflags".

=== 20 March 2014 ===
I've just released gflags 2.1.0.
The major changes are the use of CMake for the build configuration instead
of the autotools and packaging support through CPack. This release compiles
with all major compilers without warnings and passed the unit tests on
Ubuntu 12.04, Windows 7 (Visual Studio 2008 and 2010, Cygwin, MinGW), and
Mac OS X (Xcode 5.1).
The SVN repository on Google Code is now frozen and replaced by a Git
repository such that it can be used as Git submodule by projects. The main
hosting of this project remains at Google Code. Thanks to the distributed
character of Git, I can push (and pull) changes from both GitHub and Google Code
in order to keep the two public repositories in sync.
When fixing an issue for a pull request through either of these hosting
platforms, please reference the issue number as
[https://code.google.com/p/support/wiki/IssueTracker#Integration_with_version_control described here].
For the further development, I am following the
[http://nvie.com/posts/a-successful-git-branching-model/ Git branching model]
with feature branch names prefixed by "feature/" and bugfix branch names
prefixed by "bugfix/", respectively.
Binary and source distribution packages can be downloaded from
[https://github.com/schuhschuh/gflags GitHub] as Google Code no longer
permits the upload of such download packages.
=== 14 January 2013 ===
The migration of the build system to CMake is almost complete.
What remains to be done is rewriting the tests in Python such they can be
executed on non-Unix platforms and splitting them up into separate CTest tests.
Though merging these changes into the master branch yet remains to be done,
it is recommended to already start using the
[https://github.com/schuhschuh/gflags/tree/cmake-migration cmake-migration] branch.

This repository contains a C++ of the Google commandline flags module.
Documentation for the C++ implementation is in doc/. The python version of
gflags is now shipped seperately as it is completely independent of this
module.
See INSTALL for (generic) installation instructions for C++: basically
./configure && make && make install
See README_windows.txt for instructions on using under windows.
This package contains a library that implements commandline flags
processing. As such it's a replacement for getopt(). It has increased
flexibility, including built-in support for C++ types like string, and
the ability to define flags in the source file in which they're used.
The devel package contains static and debug libraries and header files
for developing applications that use the gflags package.
You can compile this under Windows, if you want. The solution file
(for VC 7.1 and later) is in this directory.
I've been told the following steps work to compile this under win64:
1) Open the provided solution file
2) Click on the Win32 target (on the right of Debug/Release)
3) Choose Configuration Manager
4) In Active Solution Platforms, choose New...
5) In "Type of select the new platform", choose x64.
In "Copy settings from:" choose Win32.
6) Ok and then Close
I don't know very much about how to install DLLs on Windows, so you'll
have to figure out that part for yourself. If you choose to just
re-use the existing .sln, make sure you set the IncludeDir's
appropriately! Look at the properties for libgflags.dll.
You can also create a static library of gflags. To do this, add
/D GFLAGS_DLL_DECL= /D GFLAGS_DLL_DECLARE_FLAG= /D GFLAGS_DLL_DEFINE_FLAG=
to the compile line of every gflags .cc file.
If you create a static library that *uses* flags (that is, DEFINEs or
DECLAREs flags), you will need to add the following to every .cc file
that defines or declares a flag (it's safe to add them to every .cc
file in your project):
/D GFLAGS_DLL_DECLARE_FLAG= /D GFLAGS_DLL_DEFINE_FLAG=

# CheckTypeSize
# -------------
#
# Check sizeof a type
#
# ::
#
# CHECK_TYPE_SIZE(TYPE VARIABLE [BUILTIN_TYPES_ONLY]
# [LANGUAGE <language>])
#
# Check if the type exists and determine its size. On return,
# "HAVE_${VARIABLE}" holds the existence of the type, and "${VARIABLE}"
# holds one of the following:
#
# ::
#
# <size> = type has non-zero size <size>
# "0" = type has arch-dependent size (see below)
# "" = type does not exist
#
# Furthermore, the variable "${VARIABLE}_CODE" holds C preprocessor code
# to define the macro "${VARIABLE}" to the size of the type, or leave
# the macro undefined if the type does not exist.
#
# The variable "${VARIABLE}" may be "0" when CMAKE_OSX_ARCHITECTURES has
# multiple architectures for building OS X universal binaries. This
# indicates that the type size varies across architectures. In this
# case "${VARIABLE}_CODE" contains C preprocessor tests mapping from
# each architecture macro to the corresponding type size. The list of
# architecture macros is stored in "${VARIABLE}_KEYS", and the value for
# each key is stored in "${VARIABLE}-${KEY}".
#
# If the BUILTIN_TYPES_ONLY option is not given, the macro checks for
# headers <sys/types.h>, <stdint.h>, and <stddef.h>, and saves results
# in HAVE_SYS_TYPES_H, HAVE_STDINT_H, and HAVE_STDDEF_H. The type size
# check automatically includes the available headers, thus supporting
# checks of types defined in the headers.
#
# If LANGUAGE is set, the specified compiler will be used to perform the
# check. Acceptable values are C and CXX
#
# Despite the name of the macro you may use it to check the size of more
# complex expressions, too. To check e.g. for the size of a struct
# member you can do something like this:
#
# ::
#
# check_type_size("((struct something*)0)->member" SIZEOF_MEMBER)
#
#
#
# The following variables may be set before calling this macro to modify
# the way the check is run:

#
# CMAKE_REQUIRED_FLAGS = string of compile command line flags
# CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
# CMAKE_REQUIRED_INCLUDES = list of include directories

<h2> <A name=cmake>Finding and Linking to gflags </A> using CMake</h2>
<p> Using gflags within a project which uses <A href="http://www.cmake.org">CMake</A> for its build system is easy. Therefore, simply add the following CMake code to your <code>CMakeLists.txt</code> file.
<pre>
find_package (gflags REQUIRED)
include_directories (${gflags_INCLUDE_DIR})
add_executable (foo main.cc)
target_link_libraries (foo gflags)
