[ solved ] ethernet server port

Hi.

Any way to define server port inside setup() with standard ethernet lib and ethernet shield w5100 and basic server code: webserver?
I need this because I'm using a sd-card to store all ethernet values ( IP, MAC,DNS, etc.. ) and read the value from the sd-card at setup, this is working nicely (zoomkat code), but so far no success for server_port. I got "server not defined in this scope" in loop() if I declare port number inside setup();

Something like this.

void setup() {
...

EthernetServer server(server_port);
...
}

But so far no success. I got all time "server not defined in this scope".

Thanks.

Declare server in global area, then assign port inn setup.

EthernetServer server;

Void setup)) {
  server = EthernetServer(server_port);

That should work. I'm not at my computer to test it.

Thanks.

But with no success.
Similar error log that I got with my previous tests.

WebServer:31: error: no matching function for call to 'EthernetServer::EthernetServer()'

I will keep trying.

Again, thanks for for tips.

I tested this and it works. I used port 23 as the default, and changed it in setup to 80.

EthernetServer server(23);

Void setup)) {
  server = EthernetServer(server_port);

Hi.

Thanks.

That is.

It's working as needed.
One of my try was define server port in global area 1st, and after recall it with a variable in setup() but without success, your 2 tips was perfect for me.

Again thanks.
