Hi. I would like to make a call to another contract described in the docs:  
[https://fuellabs.github.io/sway/v0.42.0/book/blockchain-development/calling\_contracts.html](https://fuellabs.github.io/sway/v0.42.0/book/blockchain-development/calling_contracts.html)

However i get the issue: error: This imported file must be a library. It must start with “library;”

instead of use contract::Contract is use mod contract to import the module, then in abi(contract::Contract,url).

Hello there @carlos  
Please attach the output of

```auto
 $ fuelup show

```

So we can know the version of the toolchain you are working with.

Thanks 🌴

In the end i split up the contract and abi (which is type library) into two files. However that is not clear from the docs. Now it works!
