Running solc on Ubuntu 18.04: Unhandled Exception: System.ComponentModel.Win32Exception: No such file or directory at Interop.Sys.ForkAndExecProcess

[syscoopco]

Trying to verify a smart contract on Ubuntu 18.04. Everything seems to be installed OK, according to instructions. When running the VeriSol command, the below exception raises. This path format I think is wrong: c:\verisol\sources\VeriSol\VeriSolExecuter.cs (this is a path on Windows machine, not Linux)

I suspect the space in teh path name (e.g. "smart contracts" and "mis empre") may be causing this issue. Can you remove spaces in path and try again?

Hi Shuvendu,

Thank you very much for your fast response. Spaces did matter. Also, I simplified my folders tree (I moved out them from my truffle layout):

Contract under verification: /home/user/work/smart_contracts/manicato/contracts/ManicatoTokenVeriSol.sol

I'm running VeriSol from the source root: /home/user/work/smart_contracts/manicato

OpenZeppelin folder: /home/user/work/smart_contracts/manicato/node_modules/@openzeppelin

A new error raises having to do with parsing the lines importing openzeppelin sol files. Any helps would be appreciated:

"File outside of allowed dir..." exception was solved moving the OpenZeppelin libraries (.sol files) to the same folder as the contract under verification and updating the corresponding import statements.
