[gentoo-user] Help with dev-util/cargo blocking dev-lang/rust.

[Grant Taylor]

Hi,

Would someone please point me in the proper direction to start reading 
what I need to do to resolve this problem?

[blocks B      ] dev-util/cargo ("dev-util/cargo" is blocking 
dev-lang/rust-1.30.1-r1)

  * Error: The above package list contains packages which cannot be
  * installed at the same time on the same system.

   (dev-util/cargo-0.30.0:0/0::gentoo, ebuild scheduled for merge) 
pulled in by
     =dev-util/cargo-0.30.0* required by 
(virtual/cargo-1.29.1:0/0::gentoo, ebuild scheduled for merge)

   (dev-lang/rust-1.30.1-r1:stable/1.30::gentoo, ebuild scheduled for 
merge) pulled in by
     =dev-lang/rust-1.30.1* required by 
(virtual/rust-1.30.1:0/0::gentoo, ebuild scheduled for merge)

I've been reading documentation and various blog posts, trying to find 
how to resolve this myself, but I've not had much luck.

So, will someone help me fix this cargo / rust blockage so that I can 
finish my @world emerge?

Thank you in advance.

Uninstall dev-util/cargo and emerge -1 dev-lang/rust. dev-lang/rust comes with Cargo.

I also had to

 ln -s /usr/bin/cargo-1.30.1 /usr/bin/cargo

To get things working, YMMV.

The correct way is to run `eselect rust set 1`. There are other symlinks besides cargo.

That was already set for me,  but i re-ran it, and atime on the symlink was
reset. Thanks.

Sorry posted too soon. After you install it, it should be satisfied by
dev-lang/rust-1.30.1-r1 so you no longer need dev-util/cargo

Not presently.

I removed the following packages as part of troubleshooting.

dev-util/cargo virtual/cargo dev-lang/rust virtual/rust

I then (re)installed dev-lang/rust per Andrew U.'s recommendation.

It looks like you need to unmask virtual/cargo because you need to have
virtual/cargo 1.30.1. These version numbers have to match. Are you
running a mixed keyworded system?

Once you unmask, you can install what you need for Firefox/Thunderbird
beforehand:

emerge -1 virtual/cargo dev-lang/rust

That seems to have done it.

I added virtual/cargo to /etc/portage/package.accept_keywords/cargo 
which did have dev-util/cargo ~amd64.  It now also has virtual/cargo ~amd64.

Now emerge -aDuN @world seems to be happy and is currently emerge: (2 of 3).

Thank you for your help.  :-)

> Are you running a mixed keyworded system?

I'm not completely sure what that means.  I'm guessing you're asking 
about accept_keywords.  I'm mostly (?) running stock amd64.  I have 
added ~amd64 to some packages for various reasons over the 2+ years that 
this install has been around.

I don't remember adding ~amd64 for dev-util/cargo.  I wonder if I added 
it when I wanted to try the newer Firefox.

emerge -aDuN @world is now happy (or at least not blocking / erroring 
out) and compiling things as I type this email.

Thank you again, everybody, for your help.  :-)

I switched fully to ACCEPT_KEYWORDS="~amd64" (make.conf) after running
mixed for a while. These kinds of issues come up too often and I don't
have a lot of time to solve them, plus for my dev machine I just don't
notice stable vs unstable most of the time. If something is truly
unstable from my own experience I will mask that version and downgrade.

My recommendation would be to switch over to ~amd64 for a workstation
generally. On my home server I run stable with a few unmasks, but most
of the time these are packages that have no dependencies.

I've occasionally thought about doing that.  I've just not pulled the 
trigger on that yet.  I think I added ~amd64 to ACCEPT_KEYWORDS and 
looked at how many packages were going to change, got busy / needed to 
do something else at the time, and reverted with the decision to tackle 
it some other day.  That day hasn't come yet.

ACK

That's because ~ doesn't mean unstable, it means testing. Stable in this
context means less likely to change, not less likely to fall over. Plus
the differentiation is for the ebuilds, not the software itself. You can
have a rock solid program still in the testing tree.

There is absolutely no substitute for a genuine lack of preparation.

It is also worth mentioning that ebuilds cannot be added to the tree
with "stable" flags, at least not by unprivileged contributors such as
myself.

If, for example, there is an upstream bugfix release, I will copy my
existing ebuild because neither build process nor dependencies have
changed one bit, but I am required to change keywords to unstable
anyway.

Switching to stable would require a second pull request after at least a
month has passed, and many contributors just don't bother with that.
