error: Error loading target specification: Could not find specification for target "avr-atmega328p" #133

Open 1inguini opened 5 years ago

1inguini commented 5 years ago

the shell I am using is fish, version 3.0.1, the directory I installed avr-rust is $HOME/.avr-rust/. versions of rustup and xargo are:

➤ rustup -V
rustup 1.16.0
➤ xargo -V
xargo 0.3.13
cargo 1.34.0-nightly (b33ce7fc9 2019-02-19)

I tried to build blink, only to get this error.

1inguini commented 5 years ago

It seems that the point is that I can't compile the core.

carlos4242 commented 5 years ago

This is a duplicate of #128

hercek commented 5 years ago

It does not look like a duplicate. I can compile core crate after the patches in #128. But the build does not continue since it cannot find compiler_builtins:

When I try to compile compiler_builtins from https://github.com/rust-lang-nursery/compiler-builtins then it failes because of std crate:

What is the point that some kind of compiler_builtins (which is supposed some kind of very low level stuff to avoid dependency on C runtime) depends on std crate? And what is the correct way to build blink at all?
