|
||||
</para>
|
||||
<section id="thread.build.precompiled">
|
||||
<title>Precompiled</title>
|
||||
<para>
|
||||
Using the &Boost.Thread; library in precompiled form is the way to go if you want to
|
||||
install the library to a standard place, from where your linker is able to resolve code
|
||||
in binary form. You also will want this option if compile time is a concern. Multiple
|
||||
variants are available, for different toolsets and build variants (debug/release).
|
||||
The library files are named <emphasis>{lead}boost_thread{build-specific-tags}.{extension}</emphasis>,
|
||||
where the build-specific-tags indicate the toolset used to build the library, whether it's
|
||||
a debug or release build, what version of &Boost; was used, etc.; and the lead and extension
|
||||
are the appropriate extensions for a dynamic link library or static library for the platform
|
||||
for which &Boost.Thread; is being built.
|
||||
For instance, a debug build of the dynamic library built for Win32 with VC++ 7.1 using Boost 1.34 would
|
||||
be named <emphasis>boost_thread-vc71-mt-gd-1_34.dll</emphasis>.
|
||||
More information on this should be available from the &Boost.Build; documentation.
|
||||
</para>
|
||||
<para>
|
||||
Building should be possible with the default configuration. If you are running into problems,
|
||||
it might be wise to adjust your local settings of &Boost.Build; though. Typically you will
|
||||
need to get your user-config.jam file to reflect your environment, i.e. used toolsets. Please
|
||||
refer to the &Boost.Build; documentation to learn how to do this.
|
||||
</para>
|
||||
<para>
|
||||
To create the libraries you need to open a command shell and change to the
|
||||
<emphasis>boost_root</emphasis> directory. From there you give the command
|
||||
<programlisting>bjam --toolset=<emphasis>mytoolset</emphasis> stage --with-thread</programlisting>
|
||||
Replace <emphasis>mytoolset</emphasis> with the name of your toolset, e.g. msvc-7.1 .
|
||||
This will compile and put the libraries into the <emphasis>stage</emphasis> directory which is just below the
|
||||
<emphasis>boost_root</emphasis> directory. &Boost.Build; by default will generate static and
|
||||
dynamic variants for debug and release.
|
||||
</para>
|
||||
<note>
|
||||
Invoking the above command without the --with-thread switch &Boost.Build; will build all of
|
||||
the Boost distribution, including &Boost.Thread;.
|
||||
</note>
|
||||
<para>
|
||||
The next step is to copy your libraries to a place where your linker is able to pick them up.
|
||||
It is also quite possible to leave them in the stage directory and instruct your IDE to take them
|
||||
from there.
|
||||
</para>
|
||||
<para>
|
||||
In your IDE you then need to add <emphasis>boost_root</emphasis>/boost to the paths where the compiler
|
||||
expects to find files to be included. For toolsets that support <emphasis>auto-linking</emphasis>
|
||||
it is not necessary to explicitly specify the name of the library to link against, it is sufficient
|
||||
to specify the path of the stage directory. Typically this is true on Windows. For gcc you need
|
||||
to specify the exact library name (including all the tags). Please don't forget that threading
|
||||
support must be turned on to be able to use the library. You should be able now to build your
|
||||
project from the IDE.

||||

<section id="thread.build.bjam">
|
||||
<title>&Boost.Build; Project</title>
|
||||
<para>
|
||||
If you have decided to use &Boost.Build; as a build environment for your application, you simply
|
||||
need to add a single line to your <emphasis>Jamroot</emphasis> file:
|
||||
<programlisting>use-project /boost : {path-to-boost-root} ;</programlisting>
|
||||
where <emphasis>{path-to-boost-root}</emphasis> needs to be replaced with the location of
|
||||
your copy of the boost tree.
|
||||
Later when you specify a component that needs to link against &Boost.Thread; you specify this
|
||||
as e.g.:
|
||||
<programlisting>exe myapp : {myappsources} /boost//thread ;</programlisting>
|
||||
and you are done.

</section>
|

<section id="thread.build.source">
|
||||
<title>Source Form</title>
|
||||
<para>
|
||||
Of course it is also possible to use the &Boost.Thread; library in source form.
|
||||
First you need to specify the <emphasis>boost_root</emphasis>/boost directory as
|
||||
a path where your compiler expects to find files to include. It is not easy
|
||||
to isolate the &Boost.Thread; include files from the rest of the boost
|
||||
library though. You would also need to isolate every include file that the thread
|
||||
library depends on. Next you need to copy the files from
|
||||
<emphasis>boost_root</emphasis>/libs/thread/src to your project and instruct your
|
||||
build system to compile them together with your project. Please look into the
|
||||
<emphasis>Jamfile</emphasis> in <emphasis>boost_root</emphasis>/libs/thread/build
|
||||
to find out which compiler options and defines you will need to get a clean compile.
|
||||
Using the boost library in this way is the least recommended, and should only be
|
||||
considered if avoiding dependency on &Boost.Build; is a requirement. Even if so
|
||||
it might be a better option to use the library in it's precompiled form.
|
||||
Precompiled downloads are available from the boost consulting web site, or as
|
||||
part of most linux distributions.

|

To build the &Boost.Threads; libraries using &Boost.Build;, simply change to the
|
||||
directory <emphasis>boost_root</emphasis>/libs/thread/build and execute the command:
|
||||
<programlisting>bjam -sTOOLS=<emphasis>toolset</emphasis></programlisting>
|
||||
This will create the debug and the release builds of the &Boost.Threads; library.
|
||||
<note>Invoking the above command in <emphasis>boost_root</emphasis> will build all of
|
||||
the Boost distribution, including &Boost.Threads;.</note>

|

<para>
|
||||
The Jamfile supplied with &Boost.Threads; produces a dynamic link library named
|
||||
<emphasis>boost_thread{build-specific-tags}.{extension}</emphasis>, where the build-specific
|
||||
tags indicate the toolset used to build the library, whether it's a debug or release
|
||||
build, what version of Boost was used, etc.; and the extension is the appropriate extension
|
||||
for a dynamic link library for the platform for which &Boost.Threads; is being built.
|
||||
For instance, a debug library built for Win32 with VC++ 7.1 using Boost 1.31 would
|
||||
be named <emphasis>boost_thread-vc71-mt-gd-1_31.dll</emphasis>.
|
||||
</para>
|
||||
<para>
|
||||
The source files that are used to create the &Boost.Threads; library
|
||||
are all of the *.cpp files found in <emphasis>boost_root</emphasis>/libs/thread/src.
|
||||
These need to be built with the compiler's and linker's multi-threading support enabled.
|
||||
If you want to create your own build solution you'll have to follow these same
|
||||
guidelines. One of the most frequently reported problems when trying to do this
|
||||
occurs from not enabling the compiler's and linker's support for multi-threading.

<question>

<para>Why doesn't the thread's ctor take at least a void* to pass any
|
||||
information along with the function? All other threading libs support
|

that and it makes Boost.Threads inferiour. </para>
|
||||
</question>
|
||||
<answer>
|
||||
<para>There is no need, because Boost.Threads are superiour! First
|
||||
thing is that its ctor doesn't take a function but a functor. That
|
||||
means that you can pass an object with an overloaded operator() and
|
||||
include additional data as members in that object. Beware though that
|
||||
this object is copied, use boost::ref to prevent that. Secondly, even
|
||||
a boost::function<void (void)> can carry parameters, you only have to
|
||||
use boost::bind() to create it from any function and bind its
|
||||
parameters.</para>
|
||||
<para>That is also why Boost.Threads are superiour, because they
|
||||
don't require you to pass a type-unsafe void pointer. Rather, you can
|
||||
use the flexible Boost.Functions to create a thread entry out of
|
||||
anything that can be called.</para>

It has been decided not to release the Read/Write Mutex, since the current

implementation suffers from a serious bug. The documentation of the concepts

has been included though, giving the interested reader an opportunity to study the

original concepts. Please refer to the following links if you are interested

which problems led to the decision to held back this mutex type.The issue

has been discovered before 1.33 was released and the code has

been omitted from that release. A reworked mutex is expected to appear in 1.35.

|

// 6 Jun 01
|

// WEKEMPF Initial version.
|
||||
// 30 May 02 WEKEMPF
|
||||
// Added interface to set specific cleanup handlers.
|
||||
// Removed TLS slot limits from most implementations.
|
||||
// 22 Mar 04 GlassfordM for WEKEMPF
|
||||
// Fixed: thread_specific_ptr::reset() doesn't check error returned
|
||||
// by tss::set(); tss::set() now throws if it fails.
|
||||
// Fixed: calling thread_specific_ptr::reset() or
|
||||
// thread_specific_ptr::release() causes double-delete: once on
|
||||
// reset()/release() and once on ~thread_specific_ptr().
