Unable to deploy FiatTokenV2_2 contract becouse we have made visibility of isValidSignatureNow function external in SignatureChecker.sol library

[upendra-eth]

When i am trying to deploy FiatTokenV2_2 contract using hardhat i am getting error.

The contract FiatTokenV2_2 is missing links for the following libraries:
* contracts/util/SignatureChecker.sol:SignatureChecker

This is becouse we are using external function li library contract. When i am using internal function visibilty its working file

This is because when you make library function internal/private it then limits to your code base only. But when you make it external that means any one from outside can access it. Therefore it deploys that library separately.
I hope I answered your question.
