Re: Unable to Install Rust 1.20.0 and Beyond

[Brian Woodcox <bw@InSkyData.com>]

Hi Mark,

I am marking this as *** RESOLVED ***.

Thanks for responding.  It got me thinking in a different direction.  I decided to delve into this problem by running the guix build command.

Turn out the failure was occurring during cargo tests.

Specifically:

...
  Running build/x86_64-unknown-linux-gnu/stage2-tools/x86_64-unknown-gnu/release/deps/jobserver-dd0c6bf78d70e32b

running 3 tests
test jobserver_and_j ... ok
test jobserver_exists ... test jobserver_exists has been running for over 60 seconds

At this point the system hangs forever.

After much internet searching without much for results, I decided on a hunch to increase the number of processors on my virtual machine from 1 to 2.

Tests now succeed!!  rustc is now installed.

Brian.

I am able to install the binaries for these.

Yes, with VirtualBox.

Yup, it’s imperfect with less than 2 processors in the virtual machine.
