Raspbian Buster: cargo build --release crash

help
1

Hi,
I tried to compile and run my code on Raspberry PI (which run on Linux and windows).
If I do :

  • test using > cargo test it compile test and run
  • Build in debug cargo build it compile and run
  • Build in release cargo build --release it crash
    The first error is:

Have you any advices ?

Thanks

This seems to be exactly what's noted in Rust 1.38 compatibility:

The armv7-unknown-linux-gnueabihf platform is known to have issues with certain crates such as libc.

The workaround in that linked issue is to use RUSTFLAGS=-Ccodegen-units=1.

Hi,
Thank you very much I would not have guessed a rustc issue.
