Error Cross compiling to armv7-unknown-linux-gnueabihf (error: linking with `cc` failed: exit status: 1)

When I try to compile to armv7, I get this error:

error: linking with `cc` failed: exit status: 1

This error is super long, here I have only small fragment, but I hope someone could help me . I am using rust nightly. I cannot use rust stable because then I get errors from some crate.

Here is my Cargo.toml:

json = "0.12.4"
reqwest = { version = "0.11.12", features = ["blocking", "json"] }

Do you have a C cross-toolchain installed for the target? If not, you'll need one.

[Yandros]

Using GitHub - cross-rs/cross: “Zero setup” cross compilation and “cross testing” of Rust crates and replacing cargo build … with cross build … can be a convenient way to get the cargo build … invocation to happen within a Docker container that ought to have the right toolchains and paths and env vars correctly laid out for that command to succeed.

You may then even try having a look at the corresponding Dockerfile in case you'd like your own cargo build … commands to work just as well

I have installed g++-arm-linux-gnueabihf libc6-dev-armhf-cross

I will try to do so, thank you !

Edit: it worked!
