.. Admonition:: A note to Cygwin_ and MinGW_ users
|
|
|
|
If you plan to build from the Cygwin_ bash shell, you're in the
|
|
right place. If you plan to use your tools from the Windows
|
|
command prompt, you should follow the instructions for `getting
|
|
started on Windows`_. Other command shells, such as MinGW_\ 's
|
|
MSYS, are not supported—they may or may not work.

but most libraries follow a few patterns:</p>
|
|
<ul class="pre-wrap last">
|

<li><p class="first">Some older libraries and most very small libraries place all

public headers directly into <tt class="docutils literal">boost</tt><tt class="docutils literal">/</tt>.</p>

|
|
<li><p class="first">Most libraries' public headers live in a subdirectory of

<tt class="docutils literal">boost</tt><tt class="docutils literal">/</tt>, named after the library. For example, you'll find

the Python library's <tt class="docutils literal">def.hpp</tt> header in</p>
|

<pre class="literal-block">
|
|
<tt class="docutils literal">boost</tt><tt class="docutils literal">/</tt><tt class="docutils literal">python</tt><tt class="docutils literal">/</tt><tt class="docutils literal">def.hpp</tt>.

</pre>
|

<li><p class="first">Some libraries have an “aggregate header” in <tt class="docutils literal">boost</tt><tt class="docutils literal">/</tt> that

|
<tt class="docutils literal">#include</tt>s all of the library's other headers. For
|
|
example, <a class="reference external" href="../../libs/python/doc/building.html">Boost.Python</a>'s aggregate header is</p>
|
|
<pre class="literal-block">

<tt class="docutils literal">boost</tt><tt class="docutils literal">/</tt><tt class="docutils literal">python.hpp</tt>.

|
|
<li><p class="first">Most libraries place private headers in a subdirectory called

<tt class="docutils literal">detail</tt><tt class="docutils literal">/</tt>, or <tt class="docutils literal">aux_</tt><tt class="docutils literal">/</tt>. Don't expect to find

anything you can use in these directories.</p>

<li><p class="first">The path to the <strong>boost root directory</strong> (often <tt class="docutils literal">/usr/local/</tt><tt class="docutils literal">boost_1_54_0</tt>) is

<h1><a class="toc-backref" href="#id22">4 Build a Simple Program Using Boost</a></h1>
|
|
<p>To keep things simple, let's start by using a header-only library.
|
|
The following program reads a sequence of integers from standard
|
|
input, uses Boost.Lambda to multiply each number by three, and
|
|
writes them to standard output:</p>
|
|
<pre class="literal-block">
|
|
#include <boost/lambda/lambda.hpp>
|
|
#include <iostream>
|
|
#include <iterator>
|
|
#include <algorithm>
|
|
|
|
int main()
|
|
{
|
|
using namespace boost::lambda;
|
|
typedef std::istream_iterator<int> in;
|
|
|
|
std::for_each(
|
|
in(std::cin), in(), std::cout << (_1 * 3) << " " );
|
|
}
|
|
</pre>
|
|
<p>Copy the text of this program into a file called <tt class="docutils literal">example.cpp</tt>.</p>
|
|
<p>Now, in the directory where you saved <tt class="docutils literal">example.cpp</tt>, issue the
|
|
following command:</p>
|
|
<pre class="literal-block">
|
|
c++ -I <em>path/to/</em><tt class="docutils literal">boost_1_54_0</tt> example.cpp -o example
|
|
</pre>
|
|
<p>To test the result, type:</p>
|
|
<pre class="literal-block">
|
|
echo 1 2 3 | ./example
|

<h1><a class="toc-backref" href="#id33">6 Link Your Program to a Boost Library</a></h1>
|
|
<p>To demonstrate linking with a Boost binary library, we'll use the
|
|
following simple program that extracts the subject lines from
|
|
emails. It uses the <a class="reference external" href="../../libs/regex/index.html">Boost.Regex</a> library, which has a
|
|
separately-compiled binary component.</p>
|
|
<pre class="literal-block">
|
|
#include <boost/regex.hpp>
|
|
#include <iostream>
|
|
#include <string>
|
|
|
|
int main()
|
|
{
|
|
std::string line;
|
|
boost::regex pat( "^Subject: (Re: |Aw: )*(.*)" );
|
|
|
|
while (std::cin)
|
|
{
|
|
std::getline(std::cin, line);
|
|
boost::smatch matches;
|
|
if (boost::regex_match(line, matches, pat))
|
|
std::cout << matches[2] << std::endl;
|
|
}
|
|
}
|
|
</pre>
|
|
<p>There are two main challenges associated with linking:</p>
|
|
<ol class="arabic simple">
|
|
<li>Tool configuration, e.g. choosing command-line options or IDE
|
|
build settings.</li>
|
|
<li>Identifying the library binary, among all the build variants,
|
|
whose compile configuration is compatible with the rest of your
|
|
project.</li>
|
|
</ol>
|
|
<p>There are two main ways to link to libraries:</p>
|
|
<ol class="upperalpha">
|
|
<li><p class="first">You can specify the full path to each library:</p>
|
|
<pre class="literal-block">
|
|
$ c++ -I <em>path/to/</em><tt class="docutils literal">boost_1_54_0</tt> example.cpp -o example <strong>\</strong>
|
|
<strong>~/boost/stage/lib/libboost_regex-gcc34-mt-d-1_36.a</strong>
|
|
</pre>
|
|
</li>
|
|
<li><p class="first">You can separately specify a directory to search (with <tt class="docutils literal"><span class="pre">-L</span></tt><em>directory</em>) and a library name to search for (with <tt class="docutils literal"><span class="pre">-l</span></tt><em>library</em>,<a class="footnote-reference" href="#lowercase-l" id="id14"><sup>2</sup></a> dropping the filename's leading <tt class="docutils literal">lib</tt> and trailing
|
|
suffix (<tt class="docutils literal">.a</tt> in this case):</p>
|
|
<pre class="literal-block">
|
|
$ c++ -I <em>path/to/</em><tt class="docutils literal">boost_1_54_0</tt> example.cpp -o example <strong>\</strong>
|
|
<strong>-L~/boost/stage/lib/ -lboost_regex-gcc34-mt-d-1_36</strong>
|
|
</pre>
|
|
<p>As you can see, this method is just as terse as method A for one
|
|
library; it <em>really</em> pays off when you're using multiple
|
|
libraries from the same directory. Note, however, that if you
|
|
use this method with a library that has both static (<tt class="docutils literal">.a</tt>) and
|
|
dynamic (<tt class="docutils literal">.so</tt>) builds, the system may choose one
|
|
automatically for you unless you pass a special option such as
|
|
<tt class="docutils literal"><span class="pre">-static</span></tt> on the command line.</p>
|
|
</li>
|
|
</ol>
|
|
<p>In both cases above, the bold text is what you'd add to <a class="reference internal" href="#build-a-simple-program-using-boost">the

<h1><a class="toc-backref" href="#id36">7 Conclusion and Further Resources</a></h1>
|
|
<p>This concludes your introduction to Boost and to integrating it
|
|
with your programs. As you start using Boost in earnest, there are
|
|
surely a few additional points you'll wish we had covered. One day
|
|
we may have a “Book 2 in the Getting Started series” that addresses
|
|
them. Until then, we suggest you pursue the following resources.
|
|
If you can't find what you need, or there's anything we can do to
|
|
make this document clearer, please post it to the <a class="reference external" href="http://www.boost.org/more/mailing_lists.htm#users">Boost Users'
|
|
mailing list</a>.</p>
