<p>
For applications that don't require all of the functionality of the
full Berkeley DB library, an option is provided to build a static
library with certain functionality disabled. In particular,
cryptography, hash and queue access methods, replication and
verification are all turned off. In addition, all message text
is stripped from the library. This can reduce the memory
footprint of Berkeley DB significantly.
</p>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p>
If your library has stripped messages, you can get an idea of
what text should be issued for a given error message by using
the <a href="../articles/mssgtxt/index.html" class="olink">Message
Reference for Stripped Libraries</a> guide.
</p>
</div>
<p>
In general on Windows systems, you will want to evaluate the size
of the final application, not the library build. The Microsoft LIB
file format (like UNIX archives) includes copies of all of the
object files and additional information. The linker rearranges
symbols and strips out the overhead, and the resulting application
is much smaller than the library. There is also a Visual C++
optimization to "Minimize size" that will reduce the library size
by a few percent.
</p>
<p>
A Visual C++ project file called <code class="filename">db_small</code> is
provided for this small memory configuration. During a build,
static libraries are created in <code class="filename">Release</code> or
<code class="filename">Debug</code>, respectively. The library name is
<code class="filename">libdb_small48sd.lib</code> for the debug build, or
<code class="filename">libdb_small48s.lib</code> for the release
build.</p>
<p>For assistance in further reducing the size of
the Berkeley DB library, or in building small memory footprint
libraries on other systems, please contact Berkeley DB
support.
