I notice that the actual error is in the multicast code within libinetsocket. Depending on your time/knowledge (I don't currently have a functional FreeBSD system), do you know if there are similar facilities on FreeBSD?

Alternatively we can switch off compilation of the multicast code on FreeBSD.

[Peter2121]

Sorry, I switched to another library now. Anyway, I have no answer on your question - I don't know.

[dermesser]

Well, I guess it's time to get my hands on FreeBSD again ;-)

[Peter2121]

Hope, you'll have a success ;)
