Problem verifying contract on BSC Scan

[JoeCald]

I’m trying to verify a contract I deployed on BSC but I’m getting this error. How do I fix this? Do I have to add some libraries and their contract address during scan, if how?

Compiler debug log:
Error! Unable to generate Contract ByteCode and ABI (Expected library(ies) but one or more was not provided)
Found the following ContractName(s) in source code : Address , Context , IBEP20 , IPancakeFactory , IPancakePair , IPancakeRouter01 , IPancakeRouter02 , LittleMoonWorm , Ownable , ReentrancyGuard , SafeMath , Utils
But we were unable to locate a matching bytecode (err_code_2)

Verify ERC20 token on Etherscan that was deployed through Remix: Step by Step Guide

At the previous tutorial: Create an ERC20 using Remix, without writing Solidity, we have learned how to deploy contracts with the Remix, and now in this tutorial, we will learn how to verify the deployed contracts by a single file. Cause many people deploy contracts by the Remix, so in this part, we will use the plugin FLATTENER in the Remix to help us to package all contracts file into a single file to verify. In short, all steps are: Compile contract Flatten contract Copy the whole code to…
