I'm trying to build crate with xargo as noted in readme:

curl -L https://raw.githubusercontent.com/japaric/steed/master/Xargo.std.toml > Xargo.toml
curl -LO https://raw.githubusercontent.com/japaric/steed/master/docker/x86_64-unknown-linux-steed.json
xargo build --target x86_64-unknown-linux-steed

The following error occurs:

ld.lld: error: undefined symbol: __rust_allocate_zeroed
>>> referenced by heap.rs:74 (/home/usov/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/src/liballoc/heap.rs:74)

Hmm, interesting. What crate are you building?

japaric commented 7 years ago

It seems the problem comes from using a recent nightly as #135 also failed. I don't have time to look into the cause right now but you could try switching to an older nightly in the meantime.

I'm trying to build resolve crate to see if we could use it to solve #101

Yes you are right. The problem is only reproduced with last nightly. Build successfull with 2017-04-15 nightly.

Reported to ralloc as well: redox-os/ralloc#50.
