Ubuntu's version of rustc (1.25.0) can't build dependencies for ripgrep 0.10.0

[x4121]

Sadly Ubuntu's package repos (up to bionic) contain rustc in version 1.25.0, which seems to be too old to build ripgrep dependencies.

error[E0658]: use of unstable library feature 'thread_local_state': state querying was recently added (see issue #27716)

Yup, unfortunately, you'll need to stick with ripgrep 0.9 until Ubuntu updates its Rust compiler.

Thanks for your confirmation (I'm not too deep into Rust and thought I may have gotten something wrong). Guess that change won't happen before ripgrep made it into Ubuntu, at which time this repo is (gladly) not useful anymore 🙂

@x4121 I actually think this repo could be incredibly useful! I'm certainly going to point folks to it who want an example of how to setup a ppa for distributing Rust applications. :)

Haha... damn, I was hoping some more skilled and experienced folks at Debian/Ubuntu would take responsibility for that 😂

I really do hope that I find a cleaner way of compiling Rust applications in the future. Especially when people could potentially use it as a reference 😉
