<para>If you have <application>Valgrind</application> version 3.0.0 or

higher installed and you plan on running the test suites after passing the
|
|
<option>--enable-valgrind-testing</option> parameter to
|
|
<command>configure</command>, you need to issue the following command to
|
|
change some test scripts:</para>
|
|
|
|
<screen><userinput>sed -i -e "s/logfile-fd/log-fd/" `grep -lr logfile-fd test/*sh`</userinput></screen>
|
|
|
|
<para>To test the results, issue: <command>make check</command>. Note that
|
|
if you passed the <option>--enable-exhaustive-tests</option> and
|
|
<option>--enable-valgrind-testing</option> parameters to
|
|
<command>configure</command> and then run the test suite, it will take a

|
<emphasis>very</emphasis> long time (up to 300 SBUs) and use about 375 MB

<para><parameter>--disable-thorough-tests</parameter>: This parameter is

used so that the test suite will complete in a reasonable amount of time.

Remove it if you desire more extensive tests.</para>

|
|
|
<para><option>--enable-sse</option>: This option is off by default and

should be set on if your machine has SSE capability. One way to find out if

you have SSE is to issue <command>cat /proc/cpuinfo</command> and see if
