These instructions are intended to help you get started using the Boost Libraries. This walks you through getting, building, and installing the libraries. To summarize these are the steps to get Boost built and installed:
1 | The Boost Libraries are distributed through the SourceForge file distribution system. Click here to download releases from SourceForge. And unpack the release to a convenient location. |
The Boost release includes all of the libraries and other material from the web site. It is available in ZIP, TAR.GZ, and TAR.BZ2 formats. Past releases are also available.
It is also possible to download current snapshots of work-in-progress from Boost's CVS repository.Text file line endings in the .zip file are as supplied by each library developer. This works fine for Windows, but not for Unix/Linux. The .tar.gz and .tar.bz2 files supply Unix/Linux friendly line endings.
The .tar.gz format is widely supported on Unix/Linux platforms. Some Windows compress/archive utilities can read the format as well. Because the gzip format compresses the archive as a single file rather than compressing each file individually, the .tar.gz file is smaller that the .zip file.
The .tar.bz2 format is becoming widely available on Unix/Linux platforms and is built into many tar utilities. This format differs for the .tar.gz format in the compression used, which is considerably better and therefore creates smaller files.
Text file line endings in the .tar.gz and .tar.bz2 files have been converted to newlines for ease of use on Unix/Linux platforms.
All Boost files, including the entire distribution tree including web site HTML is maintained in a CVS repository. Command line, GUI, or browser access is available.
See the much improved CVS documentation (Section F) from SourceForge, which includes links to the home pages for various GUI and command line clients.
The general procedure for command-line clients is something like this:
Read the manual for your CVS client for further information.cvs -d:pserver:anonymous@cvs.boost.sourceforge.net:/cvsroot/boost login
[Hit <return> when it asks for a password]
cvs -z3 -d:pserver:anonymous@cvs.boost.sourceforge.net:/cvsroot/boost checkout boost
cvs -d:pserver:anonymous@cvs.boost.sourceforge.net:/cvsroot/boost logout
This access is read-only; if you are a library author and wish to have CVS write access, please contact one of the moderators.
The recommended way to build and install the Boost Libraries is to use Boost.Build, the Boost Build system. The rest of these instructions explain that use, but it is up to you to use this method, or not. Note that some of the libraries also include non Boost.Build makefiles and/or project files. But all include the needed files for building with Boost.Build.
2 | The build system uses Boost.Jam, an extension of the Perforce Jam portable make replacement. You can either build this yourself, it's included with the distribution. Or obtain a prebuilt from SourceForge. To install Boost.Jam, copy the bjam executable to a location accessible in your PATH. |
Before using Boost.Build you will need to configure the compiler tools you are using. The build system's toolsets are designed to work in either of two ways:
bjam
command-line.
These variables are used by the build system to locate the tools and
invoke the necessary setup. To set the variables on the bjam
command-line you use the "-s" option. For example:3 | The following toolsets are supported by Boost.Build. For information about configuring each toolset, click its name in the leftmost column. |

The common build and install process is driven by the top-level build file (Jamfile).
4 |
First you need to change to the directory where you have the Boost distribution you downloaded. For example:
|
The default build and install attempts to build all available libraries and install to default locations the libraries and Boost header files. On Unix systems the default install location is "/usr/local", and on Windows systems the default is "C:\Boost". Within those directories libraries are installed to the "lib" subdirectory, and headers to an "include/boost-1_31" subdirectory, the version will reflect the distribution you are installing.
5 |
Invoke the build system, specifying the toolset(s) you wish to use, to build and install. For
example for GNU/GCC.
Or if you are interested only in the built libraries you can have them built and collected to a common directory without installation.
|
The build and install system can be controlled through a set of options similar in style to GNU configure options. The options allow you to, among other things, change the install location, disable building of libraries, etc. You can see a summary of the available options by invoking "bjam --help". The full invocation takes the form:
bjam [options...] [install|stage]
Action | |
---|---|
none | Only builds the Boost libraries. This lets you do the first part of what the install action normally does without copying the built libraries to the install location. |
install | Builds and installs Boost libraries and headers. |
stage | Builds the Boost libraries and copies them into a common directory. |
Option | |
--help | Shows a short summary of the options and syntax of the command. |
-sTOOLS=<toolsets> | The list of tools to compile with. Usually only one is needed. |
--prefix=PREFIX | Install architecture independent files
here. Default; C:\Boost on Win32. Default; /usr/local on Unix. Linux, etc. |
--exec-prefix=EPREFIX | Install architecture dependent files
here. Default; PREFIX |
--libdir=DIR | Install libraries here. Default; EPREFIX/lib |
--includedir=DIR | Install source headers here. The Boost
headers are installed in a version specific
"boost-<version>" subdirectory in this directory. Default; PREFIX/include |
--builddir=DIR | Build in this location instead of building within the distribution tree. This moves where the sources for the libraries are compiled to before they are installed. Recommended! |
--stagedir=DIR | When staging only, with the
"stage" action, copy to the given location. Default; ./stage |
--without-<library> | Do not build, stage, or install the specified library. |
--with-python-root[=PYTHON_ROOT] | Build Boost.Python libraries with the
Python devel packages located at PYTHON_ROOT. The Boost.Python
libraries are built only if the build can find the Python development
package at this location. Default; C:\tools\python on Win32. Default; /usr/local on Unix, Linux, etc. Default; /usr on Cygwin. |
--with-pydebug | Build Boost.Python libraries using the Python debug runtime. This builds an additional set of libraries for use with the debug version of Python. The regular versions of the Boost.Python libraries are also built. |
There are additional options as supported by Boost.Build and Boost.Jam. Of the additional options perhaps the most imporant is "-sBUILD=<features/variants>" which lets you override what is built by default. The "<features/variants>" value is a list, separated by spaces, of build requests. Features take the form of a tag and a value or values. And variants are single symbolic names for a collection of features. For example the default is to request "debug release <runtime-link>static/dynamic <threading>single/multiple", in which "debug" and "release" are variants, and the rest features with two values each.
If you have some feedback about the build and install process please drop us a line at the Boost.Build mailing list. We are particularly interested if it works for your platform and if it there is anything that you feel could be done better.
The results of building come in to forms: static libraries, and dynamic libraries. Depending on the platform the libraries produced have different names to accommodate the platform requirements. For a single Boost library the build with the default will produce eight different libraries. For example building the Boost.Datetime library on Unix type system it would produce:
|
||||||||||||
lib |
|
|||||||||||
boost_date_time |
|
|||||||||||
- | gcc |
|
||||||||||
- | mt |
|
||||||||||
- | d |
|
||||||||||
- | 1_31 |
|
||||||||||
.a |
The "lib" prefix on the libraries is a requirement on many platforms, like Unix, and on others like GCC running on Windows. The prefix is therefore added to all libraries on Unix type systems, and to static libraries on Windows. That is on Unix shared libraries and static libraries (object archives) are named respectively:
On Windows shared libraries do not have the prefix to differentiate the import libraries from static libraries. Consequently on Windows the libraries are named:
For Boost libraries the name has the "boost_" prefix to separate them from other libraries in your system.
The toolset name is an abbreviation based on the compiler you are building with. The abbreviation is composed of a short, 2 to 4 characters, tag for the compiler and a version number of the compiler's major and minor revision (if available). For example if your toolset is "gcc-3.2.3" the toolset tag would be "gcc32". The toolset abbreviations used are as follows:

Others | The first part of the toolset name. |
This tag indicates if the library is compiled with threading support. If threading is enabled "-mt" is added, otherwise nothing is added.
This specifies the type of runtime the library was compiled against, and the type of code that is compiled. More commonly this encodes the ABI variation used in the code. For each feature of the runtime system and code compilation option a single letter is added to this tag.
Key | Feature |
s | Static link to runtime. |
g | Debug runtime. |
y | Debug Python system. |
d | Debug enabled code. |
p | STLport runtime, instead of the vendor toolset runtime. |
n | STLport runtime using the "native" IO streams instead of the STLport IO streams. |
For example if you compile debug code for STLport using native IO streams, and statically link to the debug runtime the tag would be: "-sgdpn".
This is the short label for the version of the Boost Libraries. The major and minor version numbers are taken together separated by an underscore. For example version 1.31.0 would be tagged as "-1_31". The patch version number is not included because it is assumed that patch versions are upward compatible.
The extension holds the type of library. This follows the platform requirements. On Windows this is ".dll" for shared libraries, and ".lib" for static libraries including import libraries. On Unix this is ".a" for static libraries (archives), and ".so" for shared libraries. For toolsets that support it in Unix they will also have a full version extension (for example ".so.1.31.0") with a symbolic link for the un-versioned library.
Depending on your platform and configuration you may need to perform some additional configuration to get Boost to build and install.
