Can't run on Gentoo #390

Problem

Can't run examples/avr-hal-template under gentoo. Rustup was setup using rustup-init-gentoo -s. Everything was working fine under other Distros.

Some info:

Kernel: 6.1.3-gentoo-dist

❯ cargo run --bin uno-blink -- -P /dev/ttyUSB0

Would appreciate the help :)

Hm, I am a bit lost here... The error message makes me believe your LLVM was not compiled with the AVR target enabled. But rustup is supposed to ship vendored LLVM instead of relying on something from the distro? Does this work differently on gentoo maybe?

w1png · 2023-01-10T10:51:58Z

The AVR target is enabled:

Ok I recompiled rust with llvm target use flags and this error dissapeared.

I tried running rustup target add avr-atmega328p but it "does not contain component"

Rahix · 2023-01-10T12:52:42Z

What project are you building and where from? You need to use build-std to build libcore and friends alongside your code. This is usually achieved by some settings in .cargo/config.toml:

avr-hal/examples/arduino-uno/.cargo/config.toml

Lines 1 to 8 in 4c9c44c

    
           [build] 
        
           target = "../../avr-specs/avr-atmega328p.json" 
        
           [target.'cfg(target_arch = "avr")'] 
        
           runner = "ravedude uno -cb 57600" 
        
           [unstable] 
        
           build-std = ["core"]

I am trying to run cargo run --bin uno-blink -- -P /dev/ttyUSB0 in arduino uno examples.
I also tried running the template repo.

Rahix · 2023-01-10T14:55:10Z

Hm, and it is not picking up the cargo config? Can you try running this please:

cargo build -Zbuild-std=core --bin uno-blink

w1png · 2023-01-13T20:27:39Z

cargo build -Zbuild-std=core --bin uno-blink output that I need to be running nightly version

After I tried every method to use nightly build using rustup nothing worked.
Then I checked the use flags again and it turned out that I needed to enable:

>=dev-lang/rust-1.66.0:stable/1.66::gentoo llvm_targets_AVR rust-src nightly

Everything works now. Thanks for your help :)

w1png · 2023-01-13T20:34:38Z

Also a quick recap for everyone who found this issue:

Emerge rust with the following use flags:

llvm_targets_AVR llvm_targets_ARM rust-src nightly

Init rustup:

rustup-init-gentoo -s

Install the avr/arduino toolchain (wiki link)
