Make fails at 10% following instructions on Fedora 32

[sevagh]

I followed exactly the instructions here (https://github.com/avr-rust/rust#unixlinuxnix). I can't get past 20% in the make compilation.

This is one of the first errors that appears:

There are many LLVM errors like this. I'm wondering if it's related to Fedora 32's packages being too new (since it was just released a few days ago).

I've attached a bigger output txt file: output.txt

I think I'm running into a similar issue, if not the same one. Lots of errors from LLVM, but it stops at 22% for me.

@sevagh Not sure if you're still having issues with this, but I've gotten around it by creating a Docker container that can build Rust. I'm really liking this approach because 1) I don't have to think about installing dependencies anymore, and 2) it will always stay the same unless I explicitly update it.

Two versions:

Generic Rust build env: https://hub.docker.com/r/jonahbron/rust-builder
Additional convenience for building AVR fork: https://hub.docker.com/r/jonahbron/avr-rust-builder

Post about it:

@jonahbron works like a charm, thanks:

sevagh:repos $ rustup run avr rustc --version
rustc 1.37.0-dev

enum Qualifiers : uint8_t {

Perhaps the compiler is an older version that does not support specifying of enum size? This is a weird one. I imagine there will be an upstream LLVM bug to track this.

Here are my versions for reference:

cmake version 3.17.3

CMake suite maintained and supported by Kitware (kitware.com/cmake).
1.10.0
cc (GCC) 10.1.0

FWIW I'm on a rolling release distro, packages are generally always their most up-to-date version.
