Deploy the sentinel-governance contract on the testnet

[axic]

https://github.com/ewasm/sentinel-governance

• Make sure to have truffle 5.x installed: npm install -g truffle@next
• Then change truffle-config.js to point to the RPC endpoint
• Then use truffle deploy to deploy

Getting the following compile error:

> truffle migrate --network staging

    function validateAndMeter(bytes calldata input) external pure returns (bytes memory output) {

You are using truffle 4.x.

[lrettig]

Nope:

~/eth/sentinel-governance> truffle version
Truffle v5.0.0-beta.1 (core: 5.0.0-beta.1)
Solidity v0.4.25 (solc-js)

[axic]

It has the configuration to download Solidity 0.5.0 and that instruction is only picked up by truffle 5.

The code is only compiling under Solidity 0.5.0.

If you don't see "Downloading compiler..." then you have a wrong truffle version.

Make sure to reinstall truffle@next.

[lrettig]

Reinstalled truffle. It's not installing solc 0.5.0:

Weird, it is working here :(

Will post some console output in a while. One difference is I'm using node 8, but that should cause any difference..

Unfortunately the code won't compile with 0.4.25.

[axic]

It seems the very last truffle beta broke. I had an alpha, which was working.

[axic]

With latest truffle nightly it works again:

This is what I have:

$ truffle version
Truffle v5.0.0-next.18 (core: 5.0.0-beta.2)
Solidity v0.5.0 (solc-js)
Node v8.2.1

[axic]

Updated the repository, it works now with latest nightly of Truffle and the Solidity 0.5.1 releas.e

[jwasinger]

I'll give this a go tomorrow.

[axic]

@jwasinger what is the progress on this?

@axic please take a look at the deployed contract: http://ewasm.ethereum.org/explorer/account/0x793a8d040319253446F90D072D47e95719700026
