Deploying Smart Contract with Oraclize to the test net

Question

I'm having difficulty deploying my contract to the Rinkeby TestNet.

I made a local copy of the Oraclize API and saved it here:n//Users/simon/Documents/usingOraclize.sol

In the Ethereum Wallet application I've gone to Contracts->Deploy new Contract. Pasted my contract code which begins:

pragma solidity ^0.4.0;

import "usingOraclize.sol";

contract Voyager2 is usingOraclize {

And I receive the error Source "UsingOraclize.sol" not found. Can someone explain what path I need to provide to get the import working? I've tried many different variants of the above path.

Also, I came across this: oraclize_setNetwork(networkID_testNet). Is it necessary to call this in the contract before deploying?

Answer 1

The wallet is not that smart to be a linker as well. You need to provide the code of usingOraclize.sol before your Voyager2 contract and it will be compiled correctly.

pragma solidity ^0.4.18;

contract ContractA {
    function one() public pure returns(uint) {
        return 1;
    }
}

contract ContractB is ContractA {
    function two() public pure returns(uint) {
        return 2;
    }
}

something like this more or less would be ok. Consider then that for you is necessary select ContactB, which is Voyager2 in your case and you'll have the definition merged as expected.
