I believe it's a problem with riscv
& riscv-rt
crates: https://github.com/rust-embedded/riscv/issues/69
thanks for reply! so since this is a upstream problem, should i close this issue?
We can leave it open until the problem is resolved.
i am sure latest riscv crate(version 0.7.0) solved this issue. thank you guys!
Hi everybody, i am a new guy for both risc-v and rust. I have tried this example with newest stable rust 1.52.1. I just cloned this repo, and type
cargo build
, then it failed with some error such as "private mod" and so on. This is corrected by replacingk210-hal
's version with git address, this change can be found in diff.txt, which is the output ofgit diff Cargo.toml
. But then, I trycargo build
, there is a link error:error: linking with
rust-lld
failed: exit code: 1 ...// some long error about object file and link paramerror: linking with rust-lld failed: exit code: 1
= note: rust-lld: error: /tmp/k210-example/target/riscv64gc-unknown-none-elf/debug/deps/libriscv-0cd34d7ac3269d39.rlib(riscv.o): cannot link object files with different floating-point ABI rust-lld: error: /tmp/k210-example/target/riscv64gc-unknown-none-elf/debug/deps/libriscv_rt-35242cf52d273fa0.rlib(riscv-rt.o): cannot link object files with different floating-point ABI
error: aborting due to previous error
error: could not compile k210-example
here is the full output output.txt
BTW, The components i have installed list below: cargo-x86_64-unknown-linux-gnu (installed) clippy-x86_64-unknown-linux-gnu (installed) llvm-tools-preview-x86_64-unknown-linux-gnu (installed) rust-docs-x86_64-unknown-linux-gnu (installed) rust-src (installed) rust-std-riscv64gc-unknown-none-elf (installed) rust-std-x86_64-unknown-linux-gnu (installed) rustc-x86_64-unknown-linux-gnu (installed) rustfmt-x86_64-unknown-linux-gnu (installed)
if there is any information is missed here, please let me know.
In my opinion, K210 use lp64f abi, which is unusual. For risc-v64, lp64d abi is more common.
