Requirements
|

============
|
||||
|
||||
Boost.Python requires `Python 2.2`_ [#2.2]_ *or* |newer|__.
|
||||
|
||||
.. _Python 2.2: http://www.python.org/2.2
|
||||
__ http://www.python.org
|
||||
|
||||
Background
|
||||
==========
|
||||
|
||||
There are two basic models for combining C++ and Python:
|
||||
|
||||
- extending_, in which the end-user launches the Python interpreter
|
||||
executable and imports Python “extension modules” written in C++.
|
||||
Think of taking a library written in C++ and giving it a Python
|
||||
interface so Python programmers can use it. From Python, these
|
||||
modules look just like regular Python modules.
|
||||
|
||||
- embedding_, in which the end-user launches a program written
|
||||
in C++ that in turn invokes the Python interpreter as a library
|
||||
subroutine. Think of adding scriptability to an existing
|
||||
application.
|
||||
|
||||
.. _extending: http://www.python.org/doc/current/ext/intro.html
|
||||
.. _embedding: http://www.python.org/doc/current/ext/embedding.html
|
||||
|
||||
The key distinction between extending and embedding is the location
|
||||
of the C++ ``main()`` function: in the Python interpreter executable,
|
||||
or in some other program, respectively. Note that even when
|
||||
embedding Python in another program, `extension modules are often
|
||||
the best way to make C/C++ functionality accessible to Python
|
||||
code`__, so the use of extension modules is really at the heart of
|
||||
both models.
|
||||
|
||||
__ http://www.python.org/doc/current/ext/extending-with-embedding.html
|
||||
|
||||
Except in rare cases, extension modules are built as
|
||||
dynamically-loaded libraries with a single entry point, which means
|
||||
you can change them without rebuilding either the other extension
|
||||
modules or the executable containing ``main()``.
|
||||
|
||||
No-Install Quickstart
|
||||
=====================
|
||||
|
||||
There is no need to “install Boost” in order to get started using
|
||||
Boost.Python. These instructions use Boost.Build_ projects,
|
||||
which will build those binaries as soon as they're needed. Your
|
||||
first tests may take a little longer while you wait for
|
||||
Boost.Python to build, but doing things this way will save you from
|
||||
worrying about build intricacies like which library binaries to use
|
||||
for a specific compiler configuration and figuring out the right
|
||||
compiler options to use yourself.
|
||||
|
||||
.. .. raw:: html
|
||||
|
||||
<div style="width:50%">
|
||||
|
||||
.. Note:: Of course it's possible to use other build systems to
|
||||
build Boost.Python and its extensions, but they are not
|
||||
officially supported by Boost. Moreover **99% of all “I can't
|
||||
build Boost.Python” problems come from trying to use another
|
||||
build system** without first following these instructions.
|
||||
|
||||
If you want to use another system anyway, we suggest that you
|
||||
follow these instructions, and then invoke ``bjam`` with the
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
``-a -o``\ *filename*
|
||||
|
||||
options to dump the build commands it executes to a file, so
|
||||
you can see what your alternate build system needs to do.

|
||||
|
||||
Basic Procedure
|
||||
---------------
|
||||
|
||||
1. Get Boost; see sections 1 and 2 [`Unix/Linux`__, `Windows`__\ ] of the
|
||||
Boost `Getting Started Guide`_.
|
||||
|
||||
__ ../../../more/getting_started/unix-variants.html#get-boost
|
||||
__ ../../../more/getting_started/windows.html#get-boost
|
||||
|
||||
2. Get the ``bjam`` build driver. See section 5 [`Unix/Linux`__,
|
||||
`Windows`__\ ] of the Boost `Getting Started Guide`_.
|
||||
|
||||
__ ../../../more/getting_started/unix-variants.html#prepare-to-use-a-boost-library-binary
|
||||
__ ../../../more/getting_started/windows.html#prepare-to-use-a-boost-library-binary
|
||||
|
||||
|
||||
3. cd into the ``libs/python/example/quickstart/`` directory of your
|
||||
Boost installation, which contains a small example project.
|
||||
|
||||
4. Invoke ``bjam``. Replace the “\ ``stage``\ “ argument from the
|
||||
example invocation from section 5 of the `Getting Started
|
||||
Guide`_ with “\ ``test``\ ,“ to build all the test targets. Also add
|
||||
the argument “\ ``--verbose-test``\ ” to see the output generated by
|
||||
the tests when they are run.
|
||||
|
||||
On Windows, your ``bjam`` invocation might look something like:
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
C:\\boost_1_34_0\\…\\quickstart> **bjam toolset=msvc --verbose-test test**
|
||||
|
||||
and on Unix variants, perhaps,
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
~/boost_1_34_0/…/quickstart$ **bjam toolset=gcc --verbose-test test**
|
||||
|
||||
.. Admonition:: Note to Windows Users
|
||||
|
||||
For the sake of concision, the rest of this guide will use
|
||||
unix-style forward slashes in pathnames instead of the
|
||||
backslashes with which you may be more familiar. The forward
|
||||
slashes should work everywhere except in `Command Prompt`_
|
||||
windows, where you should use backslashes.
|
||||
|
||||
.. _Command Prompt: ../../../more/getting_started/windows.html#command-prompt
|
||||
|
||||
If you followed this procedure successfully, you will have built an
|
||||
extension module called ``extending`` and tested it by running a
|
||||
Python script called ``test_extending.py``. You will also have
|
||||
built and run a simple application called ``embedding`` that embeds
|
||||
python.
|
||||
|
||||
.. _Getting Started Guide: ../../../more/getting_started/index.html
|
||||
|
||||
In Case of Trouble
|
||||
------------------
|
||||
|
||||
If you're seeing lots of compiler and/or linker error messages,
|
||||
it's probably because Boost.Build is having trouble finding your
|
||||
Python installation. You might want to pass the
|
||||
``--debug-configuration`` option to ``bjam`` the first few times
|
||||
you invoke it, to make sure that Boost.Build is correctly locating
|
||||
all the parts of your Python installation. If it isn't, consider
|
||||
`Configuring Boost.Build`_ as detailed below.
|
||||
|
||||
If you're still having trouble, Someone on one of the following
|
||||
mailing lists may be able to help:
|
||||
|
||||
* The `Boost.Build mailing list`__ for issues related to Boost.Build
|
||||
* The Python `C++ Sig`__ for issues specifically related to Boost.Python
|
||||
|
||||
__ ../../../more/mailing_lists.htm#jamboost
|
||||
__ ../../../more/mailing_lists.htm#cplussig
|
||||
|
||||
In Case Everything Seemed to Work
|
||||
---------------------------------
|
||||
|
||||
Rejoice! If you're new to Boost.Python, at this point it might be
|
||||
a good idea to ignore build issues for a while and concentrate on
|
||||
learning the library by going through the tutorial_ and perhaps
|
||||
some of the `reference documentation`_, trying out what you've
|
||||
learned about the API by modifying the quickstart project.
|
||||
|
||||
.. _reference documentation: v2/reference.html
|
||||
.. _tutorial: tutorial/index.html
|
||||
|
||||
Modifying the Example Project
|
||||
-----------------------------
|
||||
|
||||
If you're content to keep your extension module forever in one
|
||||
source file called |extending.cpp|_, inside your Boost
|
||||
distribution, and import it forever as ``extending``, then you can
|
||||
stop here. However, it's likely that you will want to make a few
|
||||
changes. There are a few things you can do without having to learn
|
||||
Boost.Build_ in depth.
|
||||
|
||||
The project you just built is specified in two files in the current
|
||||
directory: |boost-build.jam|_, which tells ``bjam`` where it can
|
||||
find the interpreted code of the Boost build system, and
|
||||
|Jamroot|_, which describes the targets you just built. These
|
||||
files are heavily commented, so they should be easy to modify.
|
||||
Take care, however, to preserve whitespace. Punctuation such as
|
||||
``;`` will not be recognized as intended by ``bjam`` if it is not
|
||||
surrounded by whitespace.
|
||||
|
||||
.. |boost-build.jam| replace:: ``boost-build.jam``
|
||||
.. _boost-build.jam: ../example/quickstart/boost-build.jam
|
||||
|
||||
.. |Jamroot| replace:: ``Jamroot``
|
||||
.. _Jamroot: ../example/quickstart/Jamroot
|
||||
|
||||
.. |extending.cpp| replace:: ``extending.cpp``
|
||||
.. _extending.cpp: ../example/quickstart/extending.cpp
|
||||
|
||||
Relocate the Project
|
||||
....................
|
||||
|
||||
You'll probably want to copy this project elsewhere so you can
|
||||
change it without modifying your Boost distribution. To do that,
|
||||
simply
|
||||
|
||||
a. copy the entire ``libs/python/example/quickstart/`` directory
|
||||
into a new directory.
|
||||
|
||||
b. In the new copies of |boost-build.jam|_ and |Jamroot|_, locate
|
||||
the relative path near the top of the file that is clearly
|
||||
marked by a comment, and edit that path so that it refers to the
|
||||
same directory your Boost distribution as it referred to when
|
||||
the file was in its original location in the
|
||||
``libs/python/example/quickstart/`` directory.
|
||||
|
||||
For example, if you moved the project from
|
||||
``/home/dave/boost_1_34_0/libs/python/example/quickstart`` to
|
||||
``/home/dave/my-project``, you could change the first path in
|
||||
|boost-build.jam|_ from
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
**../../../..**\ /tools/build/v2
|
||||
|
||||
to
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
**/home/dave/boost_1_34_0**\ /tools/build/v2
|
||||
|
||||
and change the first path in |Jamroot|_ from
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
**../../../..**
|
||||
|
||||
to
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
**/home/dave/boost_1_34_0**
|
||||
|
||||
Add New or Change Names of Existing Source Files
|
||||
................................................
|
||||
|
||||
The names of additional source files involved in building your
|
||||
extension module or embedding application can be listed in
|
||||
|Jamroot|_ right alongside ``extending.cpp`` or ``embedding.cpp``
|
||||
respectively. Just be sure to leave whitespace around each
|
||||
filename::
|
||||
|
||||
… file1.cpp file2.cpp file3.cpp …
|
||||
|
||||
Naturally, if you want to change the name of a source file you can
|
||||
tell Boost.Build about it by editing the name in |Jamroot|_.
|
||||
|
||||
Change the Name of your Extension Module
|
||||
........................................
|
||||
|
||||
The name of the extension module is determined by two things:
|
||||
|
||||
1. the name in |Jamroot|_ immediately following ``python-extension``, and
|
||||
2. the name passed to ``BOOST_PYTHON_MODULE`` in |extending.cpp|_.
|
||||
|
||||
To change the name of the extension module from ``extending`` to
|
||||
``hello``, you'd edit |Jamroot|_, changing
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
python-extension **extending** : extending.cpp ;
|
||||
|
||||
to
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
python-extension **hello** : extending.cpp ;
|
||||
|
||||
and you'd edit extending.cpp, changing
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
BOOST_PYTHON_MODULE(\ **extending**\ )
|
||||
|
||||
to
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
BOOST_PYTHON_MODULE(\ **hello**\ )
|
||||
|
||||
Installing Boost.Python on your System
|
||||
======================================
|
||||
|
||||
Since Boost.Python is a separately-compiled (as opposed to
|
||||
`header-only`_) library, its user relies on the services of a
|
||||
Boost.Python library binary.
|
||||
|
||||
.. _header-only: ../../../more/getting_started/windows.html#header-only-libraries
|
||||
|
||||
If you need a regular installation of the Boost.Python library
|
||||
binaries on your system, the Boost `Getting Started Guide`_ will
|
||||
walk you through the steps of creating one. If building binaries
|
||||
from source, you might want to supply the ``--with-python``
|
||||
argument to ``bjam`` (or the ``--with-libraries=python`` argument
|
||||
to ``configure``), so only the Boost.Python binary will be built,
|
||||
rather than all the Boost binaries.
|
||||
|
||||
.. Admonition:: Windows Users: No Auto-Link Support
|
||||
|
||||
Boost.Python does not yet support the `auto-link`_ feature, so if
|
||||
you're not using the quickstart_ method, you'll have to pay
|
||||
attention to the names of generated libraries and add extra link
|
||||
arguments not shown in the `Getting Started Guide`_ to select the
|
||||
right library.
|
||||
|
||||
.. _auto-link: ../../../more/getting_started/windows.html#link-your-program-to-a-boost-library
|
||||
|
||||
.. _quickstart: `no-install quickstart`_
|
||||
|
||||
Configuring Boost.Build
|
||||
=======================
|
||||
|
||||
As described in the `Boost.Build reference manual`__, a file called
|
||||
``user-config.jam`` in your home directory [#home-dir]_ is used to
|
||||
specify the tools and libraries available to the build system. You
|
||||
may need to create or edit ``user-config.jam`` to tell Boost.Build
|
||||
how to invoke Python, ``#include`` its headers, and link with its
|
||||
libraries.
|
||||
|
||||
__ http://www.boost.orgdoc/html/bbv2/advanced.html#bbv2.advanced.configuration
|
||||
|
||||
.. Admonition:: Users of Unix-Variant OSes
|
||||
|
||||
If you are using a unix-variant OS and you ran Boost's
|
||||
``configure`` script, it may have generated a
|
||||
``user-config.jam`` for you. [#overwrite]_ If your ``configure``\
|
||||
/\ ``make`` sequence was successful and Boost.Python binaries
|
||||
were built, your ``user-config.jam`` file is probably already
|
||||
correct.
|
||||
|
||||
If you have one fairly “standard” python installation for your
|
||||
platform, you might not need to do anything special to describe it. If
|
||||
you haven't configured python in ``user-config.jam`` (and you don't
|
||||
specify ``--without-python`` on the Boost.Build command line),
|
||||
Boost.Build will automatically execute the equivalent of ::
|
||||
|
||||
import toolset : using ;
|
||||
using python ;
|
||||
|
||||
which automatically looks for Python in the most likely places.
|
||||
However, that only happens when using the Boost.Python project file
|
||||
(e.g. when referred to by another project as in the quickstart_
|
||||
method). If instead you are linking against separately-compiled
|
||||
Boost.Python binaries, you should set up a ``user-config.jam`` file
|
||||
with at least the minimal incantation above.
|
||||
|
||||
Python Configuration Parameters
|
||||
-------------------------------
|
||||
|
||||
If you have several versions of Python installed, or Python is
|
||||
installed in an unusual way, you may want to supply any or all of
|
||||
the following optional parameters to ``using python``.
|
||||
|
||||
version
|
||||
the version of Python to use. Should be in Major.Minor
|
||||
format, for example, ``2.3``. Do not include the subminor
|
||||
version (i.e. *not* ``2.5.1``). If you have multiple Python
|
||||
versions installed, the version will usually be the only
|
||||
configuration argument required.
|
||||
|
||||
cmd-or-prefix
|
||||
preferably, a command that invokes a Python interpreter.
|
||||
Alternatively, the installation prefix for Python libraries and
|
||||
header files. Only use the alternative formulation if there is
|
||||
no appropriate Python executable available.
|
||||
|
||||
includes
|
||||
the ``#include`` paths for Python headers. Normally the correct
|
||||
path(s) will be automatically deduced from ``version`` and/or
|
||||
``cmd-or-prefix``.
|
||||
|
||||
libraries
|
||||
the path to Python library binaries. On MacOS/Darwin,
|
||||
you can also pass the path of the Python framework. Normally the
|
||||
correct path(s) will be automatically deduced from ``version``
|
||||
and/or ``cmd-or-prefix``.
|
||||
|
||||
condition
|
||||
if specified, should be a set of Boost.Build
|
||||
properties that are matched against the build configuration when
|
||||
Boost.Build selects a Python configuration to use. See examples
|
||||
below for details.
|
||||
|
||||
extension-suffix
|
||||
A string to append to the name of extension
|
||||
modules before the true filename extension. You almost certainly
|
||||
don't need to use this. Usually this suffix is only used when
|
||||
targeting a Windows debug build of Python, and will be set
|
||||
automatically for you based on the value of the
|
||||
|python-debugging|_ feature. However, at least one Linux
|
||||
distribution (Ubuntu Feisty Fawn) has a specially configured
|
||||
`python-dbg`__ package that claims to use such a suffix.
|
||||

||||

Examples
|
||||
--------
|
||||
|
||||
Note that in the examples below, case and *especially whitespace* are
|
||||
significant.
|
||||
|
||||
- If you have both python 2.5 and python 2.4 installed,
|
||||
``user-config.jam`` might contain::
|
||||
|
||||
using python : 2.5 ; # Make both versions of Python available
|
||||
|
||||
using python : 2.4 ; # To build with python 2.4, add python=2.4
|
||||
# to your command line.
|
||||
|
||||
The first version configured (2.5) becomes the default. To build
|
||||
against python 2.4, add ``python=2.4`` to the ``bjam`` command line.
|
||||
|
||||
- If you have python installed in an unusual location, you might
|
||||
supply the path to the interpreter in the ``cmd-or-prefix``
|
||||
parameter::
|
||||
|
||||
using python : : /usr/local/python-2.6-beta/bin/python ;
|
||||
|
||||
- If you have a separate build of Python for use with a particular
|
||||
toolset, you might supply that toolset in the ``condition``
|
||||
parameter::
|
||||
|
||||
using python ; # use for most toolsets
|
||||
|
||||
# Use with Intel C++ toolset
|
||||
using python
|
||||
: # version
|
||||
: c:\\Devel\\Python-2.5-IntelBuild\\PCBuild\\python # cmd-or-prefix
|
||||
: # includes
|
||||
: # libraries
|
||||
: <toolset>intel # condition
|
||||
;
|
||||
|
||||
|
||||
- If you have downloaded the Python sources and built both the
|
||||
normal and the “\ `python debugging`_\ ” builds from source on
|
||||
Windows, you might see::
|
||||
|
||||
using python : 2.5 : C:\\src\\Python-2.5\\PCBuild\\python ;
|
||||
using python : 2.5 : C:\\src\\Python-2.5\\PCBuild\\python_d
|
||||
: # includes
|
||||
: # libs
|
||||
: <python-debugging>on ;
|
||||
|
||||
- You can set up your user-config.jam so a bjam built under Windows
|
||||
can build/test both Windows and Cygwin_ python extensions. Just pass
|
||||
``<target-os>cygwin`` in the ``condition`` parameter
|
||||
for the cygwin python installation::
|
||||
|
||||
# windows installation
|
||||
using python ;
|
||||
|
||||
# cygwin installation
|
||||
using python : : c:\\cygwin\\bin\\python2.5 : : : <target-os>cygwin ;
|
||||
|
||||
when you put target-os=cygwin in your build request, it should build
|
||||
with the cygwin version of python: [#flavor]_
|
||||
|
||||
bjam target-os=cygwin toolset=gcc
|
||||
|
||||
This is supposed to work the other way, too (targeting windows
|
||||
python with a Cygwin_ bjam) but it seems as though the support in
|
||||
Boost.Build's toolsets for building that way is broken at the
|
||||
time of this writing.
|
||||
|
||||
- Note that because of `the way Boost.Build currently selects target
|
||||
alternatives`__, you might have be very explicit in your build
|
||||
requests. For example, given::
|
||||
|
||||
using python : 2.5 ; # a regular windows build
|
||||
using python : 2.4 : : : : <target-os>cygwin ;
|
||||
|
||||
building with ::
|
||||
|
||||
bjam target-os=cygwin
|
||||
|
||||
will yield an error. Instead, you'll need to write::
|
||||
|
||||
bjam target-os=cygwin/python=2.4

|

Choosing a Boost.Python Library Binary
|
||||
======================================
|
||||
|
||||
If—instead of letting Boost.Build construct and link with the right
|
||||
libraries automatically—you choose to use a pre-built Boost.Python
|
||||
library, you'll need to think about which one to link with. The
|
||||
Boost.Python binary comes in both static and dynamic flavors. Take
|
||||
care to choose the right flavor for your application. [#naming]_
|
||||
|
||||
The Dynamic Binary
|
||||
------------------
|
||||
|
||||
The dynamic library is the safest and most-versatile choice:
|
||||
|
||||
- A single copy of the library code is used by all extension
|
||||
modules built with a given toolset. [#toolset-specific]_
|
||||
|
||||
- The library contains a type conversion registry. Because one
|
||||
registry is shared among all extension modules, instances of a
|
||||
class exposed to Python in one dynamically-loaded extension
|
||||
module can be passed to functions exposed in another such module.
|
||||
|
||||
The Static Binary
|
||||
-----------------
|
||||
|
||||
It might be appropriate to use the static Boost.Python library in
|
||||
any of the following cases:
|
||||
|
||||
- You are extending_ python and the types exposed in your
|
||||
dynamically-loaded extension module don't need to be used by any
|
||||
other Boost.Python extension modules, and you don't care if the
|
||||
core library code is duplicated among them.
|
||||
|
||||
- You are embedding_ python in your application and either:
|
||||
|
||||
- You are targeting a Unix variant OS other than MacOS or AIX,
|
||||
where the dynamically-loaded extension modules can “see” the
|
||||
Boost.Python library symbols that are part of the executable.
|
||||
|
||||
- Or, you have statically linked some Boost.Python extension
|
||||
modules into your application and you don't care if any
|
||||
dynamically-loaded Boost.Python extension modules are able to
|
||||
use the types exposed by your statically-linked extension
|
||||
modules (and vice-versa).
|
||||
|
||||
``#include`` Issues
|
||||
===================
|
||||
|
||||
1. If you should ever have occasion to ``#include "python.h"``
|
||||
directly in a translation unit of a program using Boost.Python,
|
||||
use ``#include "boost/python/detail/wrap_python.hpp"`` instead.
|
||||
It handles several issues necessary for use with Boost.Python,
|
||||
one of which is mentioned in the next section.
|
||||
|
||||
2. Be sure not to ``#include`` any system headers before
|
||||
``wrap_python.hpp``. This restriction is actually imposed by
|
||||
Python, or more properly, by Python's interaction with your
|
||||
operating system. See
|
||||
http://docs.python.org/ext/simpleExample.html for details.

Python Debugging Builds
|
||||
=======================
|
||||
|
||||
Python can be built in a special “python debugging” configuration
|
||||
that adds extra checks and instrumentation that can be very useful
|
||||
for developers of extension modules. The data structures used by
|
||||
the debugging configuration contain additional members, so **a
|
||||
Python executable built with python debugging enabled cannot be
|
||||
used with an extension module or library compiled without it, and
|
||||
vice-versa.**
|
||||
|
||||
Since pre-built “python debugging” versions of the Python
|
||||
executable and libraries are not supplied with most distributions
|
||||
of Python, [#get-debug-build]_ and we didn't want to force our users
|
||||
to build them, Boost.Build does not automatically enable python
|
||||
debugging in its ``debug`` build variant (which is the default).
|
||||
Instead there is a special build property called
|
||||
``python-debugging`` that, when used as a build property, will
|
||||
define the right preprocessor symbols and select the right
|
||||
libraries to link with.
|
||||
|
||||
On unix-variant platforms, the debugging versions of Python's data
|
||||
structures will only be used if the symbol ``Py_DEBUG`` is defined.
|
||||
On many windows compilers, when extension modules are built with
|
||||
the preprocessor symbol ``_DEBUG``, Python defaults to force
|
||||
linking with a special debugging version of the Python DLL. Since
|
||||
that symbol is very commonly used even when Python is not present,
|
||||
Boost.Python temporarily undefines _DEBUG when Python.h
|
||||
is #included from ``boost/python/detail/wrap_python.hpp`` - unless
|
||||
``BOOST_DEBUG_PYTHON`` is defined. The upshot is that if you want
|
||||
“python debugging”and you aren't using Boost.Build, you should make
|
||||
sure ``BOOST_DEBUG_PYTHON`` is defined, or python debugging will be
|
||||
suppressed.
|
||||
|
||||
Testing Boost.Python
|
||||
====================
|
||||
|
||||
To run the full test suite for Boost.Python, invoke ``bjam`` in the
|
||||
``libs/python/test`` subdirectory of your Boost distribution.
|
||||
|
||||
Notes for MinGW (and Cygwin with -mno-cygwin) GCC Users
|
||||
=======================================================
|
||||
|
||||
If you are using a version of Python prior to 2.4.1 with a MinGW
|
||||
prior to 3.0.0 (with binutils-2.13.90-20030111-1), you will need to
|
||||
create a MinGW-compatible version of the Python library; the one
|
||||
shipped with Python will only work with a Microsoft-compatible
|
||||
linker. Follow the instructions in the “Non-Microsoft” section of
|
||||
the “Building Extensions: Tips And Tricks” chapter in `Installing
|
||||
Python Modules`__ to create ``libpythonXX.a``, where ``XX``
|
||||
corresponds to the major and minor version numbers of your Python
|
||||
installation.

.. [#2.2] Note that although we tested earlier versions of
|
||||
Boost.Python with Python 2.2, and we don't *think* we've done
|
||||
anything to break compatibility, this release of Boost.Python
|
||||
may not have been tested with versions of Python earlier than

Be sure to read this section even if your compiler supports

auto-linking, as Boost.Python does not yet take advantage of
|
||||
that feature.
|
||||
|
||||
.. [#toolset-specific] Because of the way most \*nix platforms
|
||||
share symbols among dynamically-loaded objects, I'm not certain
|
||||
that extension modules built with different compiler toolsets
|
||||
will always use different copies of the Boost.Python library
|
||||
when loaded into the same Python instance. Not using different
|
||||
libraries could be a good thing if the compilers have compatible
|
||||
ABIs, because extension modules built with the two libraries
|
||||
would be interoperable. Otherwise, it could spell disaster,
|
||||
since an extension module and the Boost.Python library would
|
||||
have different ideas of such things as class layout. I would
|
||||
appreciate someone doing the experiment to find out what
|
||||
happens.

|

|

<p>Python 2.5 introduces a new <tt>Py_ssize_t</tt> typedef and
|
||||
two related macros (<a href=
|
||||
"http://www.python.org/dev/peps/pep-0353/">PEP 353</a>). The
|
||||
<tt><boost/python/ssize_t.hpp></tt> header imports these
|
||||
definitions into the <tt>boost::python</tt> namespace as
|
||||
<tt>ssize_t</tt>, <tt>ssize_t_max</tt>, and <tt>ssize_t_min</tt>.
|
||||
Appropriate definitions are provided for backward compatibility
|
||||
with previous Python versions.</p>
|
||||
|
||||
<h2><a name="typedefs" id="typedefs"></a>Typedefs</h2>Imports
|
||||
<tt>Py_ssize_t</tt> into the <tt>boost::python</tt> namespace if
|
||||
available, or provides an appropriate typedef for backward
|
||||
compatibility:
|
||||
<pre>
|
||||
#if PY_VERSION_HEX >= 0x02050000
|
||||
typedef Py_ssize_t ssize_t;
|
||||
#else
|
||||
typedef int ssize_t;
|
||||
#endif
|
||||
</pre>
|
||||
|
||||
<h2><a name="constants" id="constants"></a>Constants</h2>Imports
|
||||
<tt>PY_SSIZE_T_MAX</tt> and <tt>PY_SSIZE_T_MIN</tt> as constants
|
||||
into the <tt>boost::python</tt> namespace if available, or
|
||||
provides appropriate constants for backward compatibility:
|
||||
<pre>
|
||||
#if PY_VERSION_HEX >= 0x02050000
|
||||
ssize_t const ssize_t_max = PY_SSIZE_T_MAX;
|

ssize_t const ssize_t_min = PY_SSIZE_T_MIN;
