rust: where is cargo?

rust: where is cargo?

[Todor Kondić]

Hello,

I have been playing with rust and the first thing I noticed with the guix installation is that there is no cargo. More accurately, there is indeed an output of the rust package called "cargo" and there are entries for cargo with bin paths in the store, but nothing that ends up in the PATH variable (etc/profile).

So, what's the deal here? I know that guix approach is to replace package managers, but cargo is more than that and, at least, a tool needed to follow the rust book while learning.

Hi Todor!

There is, in the (as you note) cargo output:

  $ guix install rust:cargo
  $ type cargo
  cargo is /home/nckx/.guix-profile/bin/cargo
  $ realpath `command -v cargo`
  /gnu/store/krn8958...-rust-1.46.0-cargo/bin/cargo
  $ cargo search guix  
  guix = "0.1.0"    # Cross Platform Gui Library
  # wait whut no

I think we'll need more details to know why/what doesn't work for 
you.

How did you install and test cargo?

Then your configuration is broken somehow: something is messing 
with Guix's $PATH.

Do you modify $PATH anywhere, for example in your .bash_profile?

I don't think that's true.

Kind regards,

It's half true, valid to the extent that, contrary to cargo's default repository, Guix's default follows the GNU FSDG, which also requires that every other repository referenced in that one or by the community also expresses the same commitment. If there is one reference to one which doesn't, then such reference should either be replaced, removed or there must be an agreement between the parties to fix this in the referenced repository.

The act of removing such reference is sometimes done by not including the referrer package, and this is done when there is not much resource left to deal with the fact that other repository must be created.

It's common practice for free/libre system distributions to provide a “GNU FSDG” bug/issue/task tag/section for cases where they provide packages that refer to third-party repositories not committed to the GNU FSDG, along other cases not compliant with GNU FSDG. If cargo is indeed included.
