<p>There are three compile-time configuration options that assist in
debugging Berkeley DB and Berkeley DB applications:</p>
<div class="variablelist">
<dl>
<dt>
<span class="term">
<a class="link" href="build_unix_conf.html#build_unix_conf.--enable-debug">--enable-debug</a>
</span>
</dt>
<dd>If you want to build Berkeley DB with <span class="bold"><strong>-g</strong></span> as the C and C++ compiler
flag, enter --enable-debug as an argument to configure. This will create
Berkeley DB with debugging symbols, as well as load various Berkeley DB routines
that can be called directly from a debugger to display database page
content, cursor queues, and so forth. (Note that the <span class="bold"><strong>-O</strong></span>
optimization flag will still be specified. To compile with only the
<span class="bold"><strong>-g</strong></span>, explicitly set the <code class="literal">CFLAGS</code> environment variable
before configuring.)</dd>
<dt>
<span class="term">
<a class="link" href="build_unix_conf.html#build_unix_conf.--enable-diagnostic">--enable-diagnostic</a>
</span>
</dt>
<dd>If you want to build Berkeley DB with debugging run-time sanity checks and with
DIAGNOSTIC #defined during compilation, enter --enable-diagnostic as an
argument to configure. This will cause a number of special checks to be
performed when Berkeley DB is running. This flag should not be defined when
configuring to build production binaries because it degrades performance.</dd>
<dt>
<span class="term">
<a class="link" href="build_unix_conf.html#build_unix_conf.--enable-umrw">--enable-umrw</a>
</span>
</dt>
<dd>When compiling Berkeley DB for use in run-time memory consistency checkers
(in particular, programs that look for reads and writes of uninitialized
memory), use --enable-umrw as an argument to configure. This
guarantees, among other things, that Berkeley DB will completely initialize
allocated pages rather than initializing only the minimum necessary
amount.</dd>
