I am trying to deploy a contract that I have compiled with solc using solc --bin mycontract.sol.

I used to be able to paste the result into Ethereum-Wallet and deploy the contract this way. However, this does not work for this contract (I expect the binary code is to large).

I have tried for a few hours now but I simply can not find a guide showing how to deploy a contract in any other way. But I am guessing I should be able to do it somehow using the geth commandline tool.

I could potentially just paste the solidity code into Ethereum-Wallet and let it compile the code. However, the contract uses imports which I am not sure how to get into Ethereum-Wallet.

You can do it, by using online compiler and geth commandline.

Step 1: First copy your contract into https://ethereum.github.io/browser-solidity/ , on the right handside of your page you would see Bytecode,Interface,Web3 deploy and uDApp text fields. What you should be interested here is the web3 deploy text field.

Step 2: copy the text into your geth commandline , just paste and you would see , something like Contract mined! address: 0x.... transactionHash: 0x.....

Now you can use the contract address.

  • I tried doing that, but I never see the "Contract mined!..." message. I am doing this on the testnet though. I think the testnet might be having some problems. At least blocks are being generated very infrequently.

  • Are you connected to the network ( main or testnet )? or are you running in private network if so , are you mining ? @GuutBoy Commented Jun 30, 2016 at 15:42
  • I am running on the testnet (morden).

  • Also, this does not really answer the question. I specifically do not want to use the browser compiler, just solc.

  • what are the geth arguments are you passing ? See if you have --verbosity 6 , this would help you test if you have enough ether, to be able to publish, and set your account by eth.defaultAccount and eth.coinbase etc. Commented Jun 30, 2016 at 17:13
