Right now there is no real easy way. Smart contracts are programs that are executed inside a peer-to-peer // Before Solidity 0.6.0 it had to be activated through this switch. Shifting operators use shifting opcodes and thus need less gas. You can use solc as a linker meaning that it will insert the library addresses for you at those points: Either add --libraries "file.sol:Math=0x1234567890123456789012345678901234567890 file.sol:Heap=0xabCD567890123456789012345678901234567890" to your command to provide an address for each library (use commas or spaces as separators) or store the string in a file (one library per line) and run solc using --libraries fileName. at each version. Before you deploy your contract, activate the optimizer when compiling using solc --optimize --bin sourceFile.sol. configuration. Compiling for the wrong EVM version can result in wrong, strange and failing version --> Revision 98340776. restrictions on what directories it can access, "file.sol:Math=0x1234567890123456789012345678901234567890, file.sol:Heap=0xabCD567890123456789012345678901234567890", "file.sol:Math:0x1234567890123456789012345678901234567890, file.sol:Heap:0xabCD567890123456789012345678901234567890".
