It seems the dependencies are not vendored in which is a bit unfortunate and reminds me at the cbindgen situation. I am not sure what our longer-term plan here is but it seems we need to vendor them in ourselves here, too, to proceed. I guess I could ask at the Mozilla bug, though, given that Mozilla *is* (usually) vendoring in code needed.

error: aborting due to previous error

We likely need a newer Rust compiler than 1.34.2, which is unfortunate. I am inclined to avoid that, though, if that error is the only thing that prevents a successful compilation.

After some searching I decided to use a newer Rust compiler (1.36.0) instead re-introducing our tor hack from earlier where we already used a more modern Rust version than 1.26.2 when compiling Rust code.

bug_32436_v4 ( has a patch which allows me to build lucetc.
