you seem to modify ebuild with bashrc or other portage hooks - please investigate your code yourself. probably has to do with modifying vendor jsons.

stock ebuild works fine.

Comment 3 Luke-Jr 2022-07-03 19:21:28 UTC

USE='-doc -clippy -rustfmt' succeeded (FWIW using 136 GB total in /var/tmp).

However, trying to build my normal USE flags, starting from rust 1.60.0 still fails with the same error.

There is no indication my deblobbing is related. Google finds other reports of this issue with upstream. eg https://cgit.freebsd.org/ports/commit/?id=ea3a1c8a6eff20c7a4c9ed8032d396769a5ec188

Comment 5 Luke-Jr 2022-07-03 19:49:29 UTC

Found the upstream bugfix: https://github.com/rust-lang/rust/pull/94352

This didn't fix it either :(

Comment 7 Luke-Jr 2022-07-04 01:02:50 UTC

Adding the "owned.rs" part of https://github.com/rust-lang/rust/pull/95900 (the other part is n/a to this version) in addition to 94352, appears to fix this issue.

Comment 8 tt_1 2022-07-18 21:00:39 UTC

it seems all related fixes for this have landed in rust-1.62.0?

Comment 9 Luke-Jr 2022-07-18 21:07:50 UTC

(In reply to tt_1 from comment #8)

But that's not a solution since building 1.62.0 requires 1.61.0 and that requires 1.60.0 - so this still needs to get fixed in 1.60 and 1.61.

Comment 10 Luke-Jr 2022-08-20 19:36:37 UTC

dev-lang/rust-1.61.0-r2 still affected by this

Also has new errors:

error[E0432]: unresolved import `crate::os::unix::io`
 --> library/std/src/os/fd/raw.rs:9:22
  |
9 | use crate::os::unix::io::AsFd;
  |                      ^^ could not find `io` in `unix`

Just going to disable wasm for now on my end...

Sorry for the long wait time for this report.

Since a long time have passed, and many rust versions, I prefer to close this bug with a request from reporter to retest and report if broken.

If it still reproduces with latest versions, please reopen :)
