The Solidity version pragma statement in these files doesn't match any of the configured compilers in your config. This is the recommended interface for more complex and especially automated uses. Typically, developers write the smart contract code in files with the ".sol" suffix and use the Solidity compiler to translate the source code into bytecode. So in your example, pragma solidity 0.4.24; will work on any compiler from 0.4.24 and upwards, whereas Beau Gunderson for contributing the initial integration of solium https://github.com/juanfranblanco/vscode-solidity/issues/24, the initial server and error mappings.
