I justed pushed a fix. For some reason the socket was always created with an address family of AF_INET, which is for IPv4. But I remember testing this in the past… mysterious!

Hi all,

looks like things are a bit more strange. Maybe this issue is with lambdanative configuration.

I compiled another gambit and this does not segfault. However now I get an error: "address family not supported by protocol".

Hi,

has anybody an example how to successfully use open-tcp-server or open-tcp-client with IPv6 addresses? Once I tried and failed, now I forgot that I reported it already[1] and failed again.

(Note: I'm using gambit 0.9.2 - but it looks to me as if there is no related change since,.)

thanks so much

Jörg

Hello Marc,

yesterdays patch works for open-tcp-server and friends.

However open-tcp-client still does not work for me.

I figured out that by supplying just a destination address like so:

(open-tcp-client '(address: '#16(0 0 0 0 0 0 0 1) port-number: 80))

the code would still try to set up the local address to AF_INET.

Supplying a local-address: component to the settings seems a bit wierd from a usability perspective, but at least it gets me past this point. But if I do, like so:

(open-tcp-client '(address: '#16(0 0 0 0 0 0 0 1) port-number: 80 local-address: '#16(0 0 0 0 0 0 0 1) port-number: 0))

I get an error "Cannot assign requested address". Likely this calls for an improvement of ##open-tcp-client in _io.scm. But I must admit that I don't grok this codes logic.

Best

Jörg
