<h1>Obtaining the Static Analyzer</h1>
|
|
|
|
|
|
|
|
|
|
<p>This page describes how to download and install the analyzer. Once
|
|
|
|
|
the analyzer is installed, follow the <a
|
|
|
|
|
href="/scan-build.html">instructions</a> on using <tt>scan-build</tt> to
|
|
|
|
|
get started analyzing your code.</p>
|
|
|
|
|
|
|
|
|
|
<h2>Packaged Builds (Mac OS X)</h2>
|
|
|
|
|
|
|
|
|
|
<p>Semi-regular pre-built binaries of the analyzer are available on Mac
|
|
|
|
|
OS X. These are built to run on Mac OS 10.5 and later.</p>
|
|
|
|
|
|
|
|
|
|
<p>Builds are released frequently. Often the differences between build
|
|
|
|
|
numbers being a few bug fixes or minor feature improvements. When using
|
|
|
|
|
the analyzer, we recommend that you check back here occasionally for new
|
|
|
|
|
builds, especially if the build you are using is more than a couple
|
|
|
|
|
weeks old.</p>
|
|
|
|
|
|
|
|
|
|
<p>The latest build is:
|
|
|
|
|
<!--#include virtual="latest_checker.html.incl"-->
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<p>Packaged builds for other platforms may eventually be provided, but
|
|
|
|
|
we need volunteers who are willing to help provide such regular builds.
|
|
|
|
|
If you wish to help contribute regular builds of the analyzer on other
|
|
|
|
|
platforms, please email the <a
|
|
|
|
|
href="http://lists.cs.uiuc.edu/mailman/listinfo/cfe-dev">Clang
|
|
|
|
|
Developers' mailing list</a>.</p>

<h3>Using Packaged Builds</h3>
|
|
|
|
|
|
|
|
|
|
<p>To use a package build, simply unpack it anywhere. If the build
|
|
|
|
|
archive has the name <b><tt>checker-XXX.tar.bz2</tt></b> then the
|
|
|
|
|
archive will expand to a directory called <b><tt>checker-XXX</tt></b>.
|
|
|
|
|
You do not need to place this directory or the contents of this
|
|
|
|
|
directory in any special place. Uninstalling the analyzer is as simple
|
|
|
|
|
as deleting this directory.</p>
|
|
|
|
|
|
|
|
|
|
<p>Most of the files in the <b><tt>checker-XXX</tt></b> directory will
|
|
|
|
|
be supporting files for the analyzer that you can simply ignore. Most
|
|
|
|
|
users will only care about two files, which are located at the top of
|
|
|
|
|
the <b><tt>checker-XXX</tt></b> directory:</p>
|
|
|
|
|
|
|
|
|
|
<ul>
|
|
|
|
|
<li><b>scan-build</b>: <tt>scan-build</tt> is the high-level command line utility for running the analyzer</li>
|
|
|
|
|
<li><b>scan-view</b>: <tt>scan-view</tt> a companion comannd line
|
|
|
|
|
utility to <tt>scan-build</tt>, <tt>scan-view</tt> is used to view
|
|
|
|
|
analysis results generated by <tt>scan-build</tt>. There is an option
|
|
|
|
|
that one can pass to <tt>scan-build</tt> to cause <tt>scan-view</tt> to
|
|
|
|
|
run as soon as it the analysis of a build completes</li>
|
|
|
|
|
</ul>
|
|
|
|
|
|
|
|
|
|
<h4>Running scan-build</h4>
|
|
|
|
|
|
|
|
|
|
<p>For specific details on using <tt>scan-build</tt>, please see
|
|
|
|
|
<tt>scan-build</tt>'s <a href="/scan-build">documentation</a>.</p>
|
|
|
|
|
|
|
|
|
|
<p>To run <tt>scan-build</tt>, either add the
|
|
|
|
|
<b><tt>checker-XXX</tt></b> directory to your path or specify a complete
|
|
|
|
|
path for <tt>scan-build</tt> when running it. It is also possible to use
|
|
|
|
|
a symbolic link to <tt>scan-build</tt>, such one located in a directory
|
|
|
|
|
in your path. When <tt>scan-build</tt> runs it will automatically
|
|
|
|
|
determine where to find its accompanying files.</p>

<h2 id="OtherPlatforms">Other Platforms (Building the Analyzer from Source)</h2>
|
|
|
|
|
|
|
|
|
|
<p>For other platforms, you must build Clang and LLVM manually. To do
|
|
|
|
|
so, please follow the instructions for <a
|
|
|
|
|
href="http://clang.llvm.org/get_started.html#build">building Clang from
|
|
|
|
|
source code</a>.<p>
|
|
|
|
|
|
|
|
|
|
<p>Once the Clang is built, you need to add the following to your path:</p>
|
|
|
|
|
|
|
|
|
|
<ul>
|
|
|
|
|
|
2009-12-12 07:04:35 +08:00
|
|
|
<li>The location of the <tt>clang</tt> binary.
|
2009-06-09 05:21:24 +08:00
|
|
|
|
|
|
|
|
<p>For example, if you built a <em>Debug</em> build of LLVM/Clang, the
|
2009-12-12 07:04:35 +08:00
|
|
|
resultant<tt>clang</tt> binary will be in $(OBJDIR)/Debug
|
|
|
|
|
(where <tt>$(OBJDIR)</tt> is often the same as the root source directory). You
|
|
|
|
|
can also do <tt>make install</tt> to install the LLVM/Clang libaries and
|
|
|
|
|
binaries to the installation directory of your choice (specified when you run
|
2009-06-09 05:21:24 +08:00
|
|
|
<tt>configure</tt>).</p></li>
|
|
|
|
|
|
|
|
|
|
<li>The locations of the <tt>scan-build</tt> and <tt>scan-view</tt>
|
|
|
|
|
programs.
|
|
|
|
|
|
|
|
|
|
<p>Currently these are not installed using <tt>make install</tt>, and
|
2009-12-01 14:52:01 +08:00
|
|
|
are located in <tt>$(SRCDIR)/tools/clang/tools/scan-build</tt> and
|
2009-06-09 05:21:24 +08:00
|
|
|
<tt>$(SRCDIR)/tools/clang/tools/scan-view</tt> respectively (where
|
|
|
|
|
<tt>$(SRCDIR)</tt> is the root LLVM source directory). These locations
|
|
|
|
|
are subject to change.</p></li>
