I am also getting build errors on two different linux machines. One with Ubuntu 20.10 and one with ubuntu 20.04. Both have the most recent rust nightly...

Is there a specific version of clang or GCC that should be used?

[rohitjoshi]

This issue came when I ran cargo update which updated cc package. I manually changed back to v1.0.61 version and it works fine now.

@rohitjoshi How did you downgrade the cc build dependency?

Update: For anyone facing this issue, as @rohitjoshi mentioned downgrading the cc crate fixes it. This can be done by adding the following to your Cargo.toml file:

[build-dependencies.cc]
version = "=1.0.61"
features = ["parallel"]

[yiyanwannian]

after add build-dependencies.cc to Cargo.toml, but same error still over there
