Description

@drgkaleda

TL;DR;:

  • Target OS: ArchLinux on x86-64.
  • Problem: marine uses unix target.
  • Expected behaviour: use linux target.

Problem description

I am using kademlia-dht (https://crates.io/crates/kademlia-dht) in my project. But when I'm trying to deploy my project localy with

fluence service repl myService

I get an error:

# Making sure service and modules are downloaded and built...

   = help: items from traits can only be used if the trait is in scope
help: the following trait is implemented but not in scope; perhaps add a `use` for it:

Some errors have detailed explanations: E0432, E0433, E0599.
For more information about an error, try `rustc --explain E0432`.
error: could not compile `dirs` (lib) due to 3 previous errors
Error: failed to execute, exited with exit status: 101

Building the same code without marine (cargo build in service directory) works without problem.
Getting rid of kademlia-dht crate (commenting it out) solves the problem with marine cross-compiler.
