Another Mac M1 Error/Workaround

[JohnEMagee]

WOrking on FundMe, I of course ran into an issues as the default chinlink imports do not work because they are compiled in 0.6.0 and we know Mac M1 can't compile 0.6.0 so I'm working in 0.8.12.

My depenences are now based on version 0.4.0 of the chainlink-brownie-contracts and I found the most recent versions of the ETH / USD converter code:
import "@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol";
However, making a similar change to the SafeMatchChainLink doesn't work
import "@chainlink/contracts/src/v0.8/vendor/SafeMathChainlink.sol yields an error

ParserError: Source "/Users/johnmagee/.brownie/packages/smartcontractkit/chainlink-brownie-contracts@0.4.0/contracts/src/v0.8/vendor/SafeMathChainlink.sol" not found: File not found. Searched the following locations

Is there a current version of SafeMath that works with sol 0.8.12 - if so how do i find it properly - if not please let me know as I will have to alter the code to work around whatever isn't working.

Thank you

Hello @JohnEMagee
the reason is because since version 0.8.0 of solidity you don't need SafeMath at all, so that library is not update for recent solidity version, you can just delete that import and also the using statement.

Thank you

Now that I'm home and studying this part worked, but I had to also do the payable thing.

One more question - it's not an error but a warning

Warning: Visibility for constructor is ignored. If you want the contract to be non-deployable, making it "abstract" is sufficient. --> contracts/FundMe.sol:16:5:

Can you advise what this means?
