In particular, cryptography, hash and queue access methods, replication and verification are all turned off. This can reduce the memory footprint of Berkeley DB significantly.</p> <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 <b>db_small.dsp</b> is provided for this small memory configuration, but is not included in the workspace by default. To build, open Visual Studio and go to the <i>File</i> menu. Choose <i>Open Workspace</i>, change <i>Files of Type</i> to <i>Projects (.dsp)</i> and open <i>db_small.dsp</i>.</p> <p>The project supports two configurations - <i>Release</i> and <i>Debug</i>. During a build (F7), static libraries are created in <b>Release</b> or <b>Debug</b>, respectively. The library name is <b>libdb_small47sd.lib</b> for the debug build, or <b>libdb_small47s.lib</b> 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.</p> <table width="100%"><tr><td><br></td><td align=right><a href="../build_win/intro.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../build_win/test.html"><img src="../../images/next.gif" alt="Next"></a> </td></tr></table> <p><font size=1>Copyright (c) 1996,2008 Oracle.
