cryptography: error: can't find Rust compiler #89

Closed Sylva1n closed 2 years ago

Sylva1n commented 2 years ago

Hello,

I can't build cryptography since Rust compiler isn't found.

Python: 3.8.5 platform: Linux-aarch64-with pip: n/a setuptools: 60.6.0 setuptools_rust: 1.1.2

error: can't find Rust compiler

I have created the venv with this command:

/usr/local/bin/python3 -m crossenv /opt/buildroot-2020.08/output/host/aarch64-buildroot-linux-gnu/sysroot/usr/bin/python3 venv

All related rust stuff is here:

ls /opt/buildroot-2020.08/output/host/bin/*rust*

/opt/buildroot-2020.08/output/host/bin/rustc
/opt/buildroot-2020.08/output/host/bin/rust-gdb
/opt/buildroot-2020.08/output/host/bin/rust-lldb /opt/buildroot-2020.08/output/host/bin/rustdoc /opt/buildroot-2020.08/output/host/bin/rust-gdbgui

How can crossenv find rustc?

Regards

I have installed rust on my build and also setuptools_rust. Rust is now found but the compilation fails with:
