[Pkg-rust-maintainers] Bug#884775: /usr/bin/rustc: Error Compiling Code: "attempt to use impure library"

[Frederick Muriithi]

Package: rustc
Version: 1.14.0+dfsg1-3
Severity: important
File: /usr/bin/rustc

Dear Maintainer,


I wanted to learn rust, following the tutorial/book at
https://doc.rust-lang.org/book/second-edition/

I first of all, installed rust using the rustup tool as directed in the book at
https://doc.rust-lang.org/book/second-edition/ch01-01-installation.html

On compiling, the code failed with the error :

error: linking with `cc` failed: exit code: 1

I thus searched on google, and even started off a StackOverflow thread
on this issue at
https://stackoverflow.com/questions/47737761/rust-on-debian-9-2-error-due-to-impure-library

After giving it a while, I thought it might be the interaction between
the rustc installed via rustup
and the system libraries that was causing the errors, so I unistalled
that via rustup, and installed
the rustc that is present in the Debian repository, rustc
(1.14.0+dfsg1-3) and tried to compile the
hello world program again.
I got a similar error with this rustc too:

error: linking with `cc` failed: exit code: 1

I had expected rustc to compile main.rs into something I could execute
that would then print out "Hello, world!"
