我的问题:当我尝试
cargo build
我的 avr_hal 项目时,它会抛出 error: linking with avr-gcc failed: exit status: 1
。
完整错误文本(mre):
WARN rustc_codegen_ssa::back::link Linker does not support -no-pie command line option. Retrying without.
error: linking with `avr-gcc` failed: exit status: 1

= note: some `extern` functions couldn't be found; some native libraries may need to be installed or have their path specified
= note: use the `-l` flag to specify native libraries to link
= note: use the `cargo:rustc-link-lib` directive to specify the native libraries to link with Cargo (see https://doc.rust-lang.org/cargo/reference/build-scripts.html#cargorustc-link-libkindname)
造成这种情况的原因以及如何解决? (一般使用avr_hal时是否可以定义全局分配器?)
安装
cargo-generate
- cargo install cargo-generate
奔跑
cargo generate --git https://github.com/rahix/avr-hal-template.git --name avrgcc-linking-failed-mre
(我用的是Uno)
添加
avrgcc-linking-failed-mre/.cargo/config.toml
[build]
target = "avr-specs/avr-atmega328p.json"
[unstable]
build-std = ["core", "alloc"]
avrgcc-linking-failed-mre/src/main.rs
#![no_std]
#![no_main]
use libc_alloc::LibcAlloc;
use panic_halt as _;
extern crate alloc;
#[arduino_hal::entry]
fn main() -> ! {
"123".replace("1", "4");
loop {}
}
#[global_allocator]
static ALLOCATOR: LibcAlloc = LibcAlloc;
libc_alloc = "1.0.5"
添加到 avrgcc-linking-failed-mre/Cargo.toml
