Fail to Deploy Simple Solidity Contract via Remix

Question

Why does Remix fail to deploy the simple contract (simplified from the Mastering Ethereum book https://github.com/ethereumbook/ethereumbook/blob/develop/code/Solidity/Faucet2.sol )? --

pragma solidity ^0.4.19; contract Faucet { function withdraw(uint withdraw_amount) public { require(withdraw_amount <= 100000000000000000); msg.sender.transfer(withdraw_amount); } function () external payable {} }

No matter how I raise gasLimit and/or gasPrice

Your code is fine (I have also tried it myself). From what I see above you are also sending a value along with the deploy. Since you have not defined a constructor yourself the default one is being called which is not payable. If you want to send ether when you deploy the contract you should also define a payable constructor.

So were you able to deploy the exact code with Remix? If you had to make modification for it to be deploy-able, what did you change?

Yes, the exact same code. As I said you must set the value to 0 ether when you deploy since you do not have a payable constructor.

You right. I totally confused the "Value" on the Remix interface with gasPrice.
