Ethereum Wallet not mining

Question

I installed latest Ethereum Wallent and I connected on test network and I clicked on Start Mining (Testnet only), but nothing is happening. I still have 0 ETH in my account.

I'm not sure if it's bad a design or a bug, I have no idea if it works.

Also I've tried via console 1. geth console 2. in new console geth attach 3. miner.start(2)

I get this error

Error: etherbase missing: etherbase address must be explicitly specified

Not sure how to start miner to get some test ETHs

Answer 1

You need to have at least one account, so that the client knows where to send the mined ETH. You can make a new account with personal.newAccount("mypassword123"). Then check that the account is set with eth.coinbase

Answer 2

From the console,

1. You have to create an account first by :

   personal.newAccount("password")

2. If you already had it, then skip 1 and select your account by this command:

   miner.setEtherbase(personal.listAccounts[0])

3. Mine

   miner.start(2)
