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.
