ocamlnet servers fail to start on Mac OSX

ocamlnet servers fail to start on Mac OSX

[Joel Reymont]

I'm tried to bring up examples/cgi/netcgi2-plex/netplex and got a  
bunch of messages like this, plus a runaway server continually  
forking itself.

[Mon Apr  2 17:30:51 2007] [netplex.controller] [crit] Exception in  
workload manager, function adjust: Unix.Unix_error(15, "socketpair", "")

I also got Unix.Unix_error(49, "", "") when trying to start the  
nethttpd server example. Error 49 is "Cannot bind to an address", I  
believe.

There's no problem running the examples on Linux.

	Thanks, Joel

15 is EMFILE - too many file descriptors. Maybe you have to increase
some limit. Or this is a follow-up error.

No, 49 is EAFNOSUPPORT - address family not supported. I do not know
MacOS very much, but can it be some additional component needs to be
installed? Do you use an IPv4 or IPv6 address?

You can easily translate the numbers by:

# (Obj.magic 49:Unix.error);;
- : Unix.error = Unix.EAFNOSUPPORT

They are the same on all platforms.

Yeah, I'm primarily developing on Linux, but there is nothing
Linux-specific. From time to time I am testing on NetBSD or FreeBSD
which are quite similar to the MacOS kernel.

I disabled IPv6 in network preferences after getting this error but I  
still get it.

I use IPv4 addressing.
