unknown debugging option no-trans

[carlos L]

Hi guys, Ive just installed the rust layer on spacemacs, racer works ok but I'm getting "unknown debugging option no-trans" on my flycheck in the first line of my code...

rust and flycheck seems ok

Syntax checkers for buffer main.rs in rust-mode:

  rust-cargo
    - may enable:  yes
    - predicate:   t
    - executable:  Found at /home/yo/.cargo/bin/cargo
    - Cargo.toml:  Found
    - Crate type:  bin
    - Binary name: rustD

  rust
    - may enable: yes
    - predicate:  t
    - executable: Found at /home/yo/.cargo/bin/rustc

Flycheck Mode is enabled. Use SPC u C-c ! x to enable disabled checkers.

--------------------

Flycheck version: 31snapshot (package: 20170415.1006)
Emacs version:    25.3.1
System:           x86_64-pc-linux-gnu
Window system:    x

what could be the problem here???

thank you so much guys, any question please let me know...

Flycheck version: 31snapshot (package: 20170415.1006)

Try updating the flycheck and flycheck-rust packages.

newest version of rust just updated to change the no-trans option to no-codegen

See https://github.com/w0rp/ale/pull/1806

I tried compiling with no-trans using flycheck-compile and on term:

cargo rustc --bin hello_world -- -Z no-trans -Z unstable-options --error-format\=json --test

{"message":"unknown debugging option: `no-trans`","code":null,"level":"error","spans":[],"children":[],"rendered":"error: unknown debugging option: `no-trans`\n\n"}
error: Could not compile `hello_world`.

But changing it to no-codegen on term works 😄

cargo rustc --bin hello_world -- -Z no-codegen -Z unstable-options --error-format\=json --test
Finished dev [unoptimized + debuginfo] target(s) in 0.36s

Trying to get a grips of lisp to do a pull request and change it to no-codegen on flycheck too.

@ParityB1t Thanks, but we cannot use -Z no-codegen on stable, can we? So I'd rather go with flycheck/flycheck#1501 instead.

I'm closing this issue because we haven't been using -Z no-trans in a while.
