<strong>I can't compile and run multithreaded applications.</strong>
</span>
<p>Special compile-time flags are required when compiling threaded
applications on FreeBSD. If you are compiling a threaded application,
you must compile with the _THREAD_SAFE and -pthread flags:</p>
<pre class="programlisting">cc -D_THREAD_SAFE -pthread ...</pre>
<p>The Berkeley DB library will automatically build with the correct options.</p>

<strong>I see fsync and close system call failures when accessing
databases or log files on NFS-mounted filesystems.</strong>
</span>
<p>Some FreeBSD releases are known to return ENOLCK from fsync and close
calls on NFS-mounted filesystems, even though the call has succeeded.
The Berkeley DB code should be modified to ignore ENOLCK errors, or no Berkeley DB
files should be placed on NFS-mounted filesystems on these systems.</p>
