Hi there,<br>
<br>
I've just upgraded our live555 version (from <span
style="font-family: 'Courier New,courier';">2011.06.12 to </span><span
style=" font-family:'Courier New,courier';">2012.05.17) and
RTSPClient::connectToServer is failing on Windows.</span> The
following check fails:<br>
<br>
<u><span style=" font-family:'Courier New,courier';"></span></u><tt>int
const err = envir().getErrno();<br>
if (err == EINPROGRESS || err == EWOULDBLOCK) {<br>
...<br>
}</tt><br>
<br>
I read Ross Finlayson's <a
href="http://lists.live555.com/pipermail/live-devel/2012-January/014432.html">response
to a previous post</a> by Jeff Shanab, where he added EWOULDBLOCK
as a platform-independent solution. However, it turns out
EWOULDBLOCK != WSAEWOULDBLOCK.<br>
<br>
<u>winerror.h</u><br>
<tt>#define WSAEWOULDBLOCK 10035L<br>
</tt><u>errno.h</u><br>
<tt>#define EWOULDBLOCK 140</tt><br>
<u>winsock.h / winsock2.h</u><br>
<tt>#if 0<br>
#define EWOULDBLOCK WSAEWOULDBLOCK<br>
</tt><br>
See <a
href="http://connect.microsoft.com/VisualStudio/feedback/details/509380/errno-h-socket-return-codes-now-inconsistent-with-wsagetlasterror">this
feedback entry</a> and <a
href="http://msdn.microsoft.com/en-us/library/windows/desktop/ms737828%28v=vs.85%29.aspx">MSDN
Error Codes</a>. Seems like in VS2010 they broke compatibility
with Berkeley? The #if 0 is a bit of a lol. :)<br>
<br>
There used to be a workaround in NetCommon.h ln 38, however it is
now commented out in 2012.05.17:<br>
<tt>//#define EWOULDBLOCK WSAEWOULDBLOCK</tt><br>
<br>
This results in Windows builds being unable to connect.<tt></tt> As
a temporary workaround, I've changed my NetCommon.h to read:<br>
<tt>#undef EWOULDBLOCK<br>
#define EWOULDBLOCK WSAEWOULDBLOCK<br>
#undef EINPROGRESS<br>
#define EINPROGRESS WSAEWOULDBLOCK<br>
#undef EAGAIN<br>
#define EAGAIN WSAEWOULDBLOCK<br>
#undef EINTR<br>
#define EINTR WSAEINTR</tt><br>
<br>
This appears to work again. Is this solution correct?<br>
<br>
Thanks for your help,<br>
