I have upgraded to VS 8.0 Standard and when compiling ASIO errors on the following:<br> <br> 1&gt;Unknown compiler version - please run the configure tests and report the results<br> 1&gt;C:\tor\trunk\lib\boost\boost/asio/detail/socket_types.hpp(27) : fatal error C1189: #error :&nbsp;&nbsp;WinSock.h has already been included<br>
 <br> Is this a known problem?</blockquote><div><br>What do you mean by &#39;compiling asio&#39;? It is a header-only library. :)<br><br>The problem you&#39;re seeing is because the (old) winsock.h header has been included. Most people that see this do because they&#39;ve included windows.h *before* the asio headers.<br>
<br>You can get around this by defining WIN32_LEAN_AND_MEAN (something like that) before including windows.h, or just by including windows.h after everything else.<br><br>Regards,<br>Darren<br></div></div>
