Greeter Contract - deploy command results in "undefined"

Question

I am trying to deploy the Greeter contract on a private test chain following this guide (Deploying the Greeter contract via the geth CLI is not registering in my private blockchain)

When I get to the "var greeter =" command pasted below, it runs but only ever returns "undefined", it does not look like the contract ever deploys.

Can anyone point me in the right direction please

thanks, P

var greeter = greeterContract.new(_greeting, {from: eth.accounts[0], data: greeterCompiled["<stdin>:greeter"].code, gas:20000000000}, function(e, contract) { 
  if (!e) { 
   if (!contract.address) { 
     console.log("Contract transaction send: TransactionHash: " + contract.transactionHash + " waiting to be mined..."); 
   } else { 
     console.log("Contract mined! Address: " + contract.address); console.log(contract); 
   } 
  }  
})

Variable declarations will return undefined. Its not an error.

In order to get contract address you need to mine in your private network. Make sure that your are mining.

Hi Gokulnath, thank you for the reply. I do understand that undefined is not an error, however I expected to see output "Contract mined! Address: " + contract.address". I am mining, so I'm not sure where I am going wrong. – user6307 Mar 30 '17 at 20:12

I found the issue, I have failed to unlock the account eth.account[0] (which I was using to deploy the contract), prior to attempting to deploy the contract.

After running personal.unlockAccount(eth.accounts[0]); the contract successfully deployed!
