`make static-bindgen` failed about rust_icu HOT 8 CLOSED

The immediate workaround for you is to have bindgen in your $PATH as the error message indicates.
You can do that right now without any input from this end.

A more fundamental issue is that we rely on the presence of bindgen on the system. This should probably be fixed to remove dev annoyance.

Yes, I already have bindgen in my $PATH, and the error still occurs:

❯ where bindgen
/Users/col/.cargo/bin/bindgen
❯ bindgen --version
bindgen 0.59.2

from rust_icu.

Is this a Mac-specific thing perhaps?

I don't have a Mac so don't know why the script would not honor your $PATH. I would think that it should.

may be related: rust-lang/cargo#9096

currently it's a unstable feature for cargo.

OK, so this should work in a container (and does on my end!).

Perhaps it could be fixed by referring to the binary's absolute path since the buildenv containers are known and fixed.

This is fixed, and is now guarded by a presubmit check at #279

from rust_icu.

To wit, the issue was that make static-bindgen mounted cargo's bin directory from the host into the container, and there is a library version mismatch between most hosts and the rust:1.70 container, where the container's required glibc is way newer than that of the host.

This is now fixed, by not mounting the host's cargo bin into the containers when make static-bindgen runs.
