How to deploy dependent contracts with Ethereum Wallet

Question

I have two contracts (i.e. contractA, contractB) located in different files (i.e, contractA.sol, contractB.sol) to deploy. The contractB is dependent on contractA. In contractB.sol,

import "contractA";

The contractA has been deployed successfully to Testnet with Ethereum Wallet by putting source of contractA in tab "SOLIDITY CONTRACT SOURCE CODE". When contractB was deployed, Ethereum Wallet complained:

Could not compile source code. Source "contractA.sol" not found.

How to fix it?

Answer 1

You should be able to just include the source for contractA in the tab with contractB's source. For instance:

contract A {
    ...
}

contract B {
    A a;
    function B(address _a) {
        a = A(_a);
    }
    ....
}

When you compile and go to deploy, just make sure you select B. (And make sure that the A code is identical to what you've already deployed.)

That said, the command line Solidity compiler handles import instructions quite nicely, as does the Javascript implementation. (See https://github.com/ethereum/solc-js)
