Solidity Compiler Version

[Miller-kk]

I wanna change solidity's compiler version. (current version is v0.5.12.)

i installed solc v0.4.24 and changed my env path.

But I get the following error. Does securify currently support only solc in version 0.5.12?

--------------- error console------------------------- solc.exceptions.SolcError: fixed_pragma.sol:1:1: ParserError: Source file requires different compiler version (current compiler is 0.5.12-develop.2019.8.13+commit.e91c6acb.Linux.g++ - note that nightly builds are considered to be strictly less than the released version pragma solidity 0.4.24; ^---------------------^

First of all, we do not support versions before 0.5. From the error you are getting, it seems that you are still using the 0.5.12 version. In order to use another version of the solidity compiler you should either use the --solidity flag or set the environment variable SOLC_BINARY to the version you want.
