<p>This section describes main targets types that Boost.Build supports
of-of-the-box. Unless otherwise noted, all mentioned main target rules
have the common signature, described in <a href="advanced/targets.html" title="Declaring Targets">the section called “Declaring Targets”</a>.
</p>

<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="bbv2.tasks.programs"></a>Programs</h2></div></div></div>
<a class="indexterm" name="id2589735"></a><p>Programs are created using the <code class="computeroutput">exe</code> rule, which
follows the <a href="advanced/targets.html#bbv2.main-target-rule-syntax">common
syntax</a>. For example:
</p>
<pre class="programlisting">
exe hello : hello.cpp some_library.lib /some_project//library
: <threading>multi
;
</pre>
<p>
This will create an executable file from the sources -- in this case,
one C++ file, one library file present in the same directory, and
another library that is created by Boost.Build. Generally, sources
can include C and C++ files, object files and libraries. Boost.Build
will automatically try to convert targets of other types.

On Windows, if an application uses dynamic libraries, and both
the application and the libraries are built by Boost.Build, its not
possible to immediately run the application, because the
<code class="literal">PATH</code> environment variable should include the path
to the libraries. It means you have to either add the paths
manually, or place the application and the libraries to the same
directory. See <a href="tasks/installing.html" title="Installing">the section called “Installing”</a>.
