However, the <b>db.h</b> include file that -was distributed with Berkeley DB 1.85 is not compatible with the <b>db.h</b> -file distributed with Berkeley DB version 2, so you will have to install them -in different locations. In addition, both the Berkeley DB 1.85 and Berkeley DB -version 2 libraries are named <b>libdb.a</b>. -<p>As the Berkeley DB 1.85 library did not have an installation target in the -Makefile, there's no way to know exactly where it was installed on the -system. In addition, many vendors included it in the C library instead -of as a separate library, and so it may actually be part of libc and the -<b>db.h</b> include file may be installed in <b>/usr/include</b>. -<p>For these reasons, the simplest way to maintain both libraries is to -install Berkeley DB version 2 in a completely separate area of your system. -The Berkeley DB version 2 installation process allows you to install into a -standalone directory hierarchy on your system. See the -<a href="../../ref/build_unix/intro.html">Building for UNIX systems</a> -documentation for more information and instructions on how to install the -Berkeley DB version 2 library, include files and documentation into specific -locations. -<p><li>Alternatively, you can replace Berkeley DB 1.85 on your system with Berkeley DB -version 2. In this case, you'll probably want to install Berkeley DB version -2 in the normal place on your system, wherever that may be, and delete -the Berkeley DB 1.85 include files, manual pages and libraries. -<p>To replace 1.85 with version 2, you must either convert your 1.85 -applications to use the version 2 API or build the Berkeley DB version 2 library -to include Berkeley DB 1.85 interface compatibility code. Whether converting -your applications to use the version 2 interface or using the version 1.85 -compatibility API, you will need to recompile or relink your 1.85 -applications, and you must convert any persistent application databases -to the Berkeley DB version 2 database formats. -<p>If you want to recompile your Berkeley DB 1.85 applications, you will have to -change them to include the file <b>db_185.h</b> instead of -<b>db.h</b>. (The <b>db_185.h</b> file is automatically installed -during the Berkeley DB version 2 installation process.) You can then recompile -the applications, linking them against the Berkeley DB version 2 library. -<p>For more information on compiling the Berkeley DB 1.85 compatibility code into -the Berkeley DB version 2 library, see <a href="../../ref/build_unix/intro.html">Building for UNIX platforms</a>. -<p>For more information on converting databases from the Berkeley DB 1.85 formats -to the Berkeley DB version 2 formats, see the <a href="../../utility/db_dump.html">db_dump185</a> and -<a href="../../utility/db_load.html">db_load</a> documentation. -<p><li>Finally, although we certainly do not recommend it, it is possible to -load both Berkeley DB 1.85 and Berkeley DB version 2 into the same library. -Similarly, it is possible to use both Berkeley DB 1.85 and Berkeley DB version 2 -within a single application, although it is not possible to use them from -within the same file. -<p>The name space in Berkeley DB version 2 has been changed from that of previous -Berkeley DB versions, notably version 1.85, for portability and consistency -reasons. The only name collisions in the two libraries are the names used -by the historic <a href="../../api_c/dbm.html">dbm</a>, <a href="../../api_c/dbm.html">ndbm</a> and <a href="../../api_c/hsearch.html">hsearch</a> interfaces, -and the Berkeley DB 1.85 compatibility interfaces in the Berkeley DB version 2 -library. -<p>If you are loading both Berkeley DB 1.85 and Berkeley DB version 2 into a single -library, remove the historic interfaces from one of the two library -builds, and configure the Berkeley DB version 2 build to not include the Berkeley DB -1.85 compatibility API, otherwise you could have collisions and undefined -behavior. This can be done by editing the library Makefiles and -reconfiguring and rebuilding the Berkeley DB version 2 library. Obviously, if -you use the historic interfaces, you will get the version in the library -from which you did not remove them. Similarly, you will not be able to -access Berkeley DB version 2 files using the Berkeley DB 1.85 compatibility interface, -since you have removed that from the library as well. -</ol> -<table><tr><td><br></td><td width="1%"><a href="../../ref/upgrade.2.0/intro.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/upgrade.2.0/convert.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> -</body> -</html> |
