example server crash on Visual Studio 2017 for Mac with Mono 5.4.0 #38

Closed Xdeon closed 7 years ago

Xdeon commented 7 years ago

Hi,

The attempt to run the CoAP.Server.NET45 project on Visual Studio for Mac community version with Mono 5.4.0.201 failed with following output:

mono_w32socket_convert_error: no translation into winsock error for (6) "Device not configured"

This seems to work on Mono 4.8, but if one would like to use this library in a Xamarin iOS project than there is no obvious way of changing the underlying building environment.

It will be very appreciated if you could give some hints on how to fix this.

Thank you.

Best regards

Wish I could debug this, but I don't have a MAC.

Two things to try:

  1. Change line 324 of UDPChannel.cs to "socket.Socket.IOControl(SIO_UDP_CONNRESET, new byte[4]{0}, null);" The problem may be that the value is not long enough. I would be surprised if that was the problem however.
  2. Just comment out the line, the code expects that it should be throwing an exception in this case and is coded defensively to prevent that from being a problem. This does not seem to be running correctly with your version of mono.

It seems to run file on 5.2.0.224 on a linux system based on travis-cl logs.

Xdeon commented 7 years ago

Thanks a lot for such a quick reply!

It turns out the first solution makes no difference, but commenting out this line solved the problem.

I guess this may be a Mac specific problem. Anyway, thank you again for your help.

should now be fixed
