You also have to add support for at least one of the following handlers by specifying the <span class="option">--with-XXXX</span> configure switch to your PHP configure line. </p> <div class="warning"><b class="warning">Warning</b> <p class="para"> After configuring and compiling PHP you must execute the following test from commandline: <i>php run-tests.php ext/dba</i>. This shows whether your combination of handlers works. Most problematic are <i>dbm</i> and <i>ndbm</i> which conflict with many installations. The reason for this is that on several systems these libraries are part of more than one other library. The configuration test only prevents you from configuring malfunctioning single handlers but not combinations. </p> </div> <p class="para"> <table border="5"> <caption><b>Supported DBA handlers</b></caption> <colgroup> <thead valign="middle"> <tr valign="middle"> <th colspan="1">Handler</th> <th colspan="1">Configure Switch</th> </tr> </thead> <tbody valign="middle" class="tbody"> <tr valign="middle"> <td colspan="1" rowspan="1" align="left"><i>dbm</i></td> <td colspan="1" rowspan="1" align="left"> <p class="para"> To enable support for dbm add <span class="option">--with-dbm[=DIR]</span>. <blockquote><p><b class="note">Note</b>: dbm normally is a wrapper which often results in failures.
