Detect missing installed sources

[pacak]

Ideally it should detect it and complain. Thank you for the report :)

I guess I need to know a bit more about your setup in order to be able to replicate the problem. Is it still crashing if you drop the target folder? Is it working at all on your machine? Do you have rust sources installed with whatever the rustup invocation is?

[pacak]

Also is it usual x86_64 Linux with no crosscompilation?

This was it. It now works correctly after running rustup component add rust-src. Thanks for your help!
