  34 <PRE>DL_LAZY is only needed for future compatibility, as stated in the
  35 OpenBSD 3.0 man page.
  36 man dlopen reports:
  37 &quot;The path argument can either be an absolute pathname or it can be of
  38 the form ``lib&lt;name&gt;.so[.xx[.yy]]'' in which case the same library
  39 search rules apply that are used for ``intrinsic'' shared library
  40 searches.  The second argument currently has no effect, but should be
  41 set to DL_LAZY for future compatibility.&quot;

  54 </I>&gt;<i> &gt;Hello Peeps
  55 </I>&gt;<i> &gt;
  56 </I>&gt;<i> &gt;On OpenBSD the flags to dlopen should be DL_LAZY, which is for future
  57 </I>&gt;<i> &gt;compatibility (according to its manpage), also, it needs an underscore
  58 </I>&gt;<i> &gt;prefixed onto any symbol you try and get from the modules (i believe
  59 </I>&gt;<i> &gt;this is due to the a.out binary format, and it isn't handled in BSD's
  60 </I>&gt;<i> &gt;dl* routines).
  61 </I>&gt;<i> &gt;I just tried a compile on OpenBSD 3.0, and ircservices doesn't handle
  62 </I>&gt;<i> &gt;either of these quirks, it should be a relatively simple
  63 </I>&gt;<i> &gt;makefile/configure change to get ircservices to account for them.
  64 </I>&gt;<i> &gt;
