Actually I was trying to reproduce the bug that xargo discards the built libstd from /tmp/ and writes usual libstd to ~/.xargo, but now, after rustup update it doesn't even builds std. Maybe xargo should be monitored by Travis to ensure it stays afloat as Rust Nightly goes on?

I came across the same issue. The build script is looking for files in the directory ~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/src/compiler-rt, which doesn't exist. I don't know why.

As a workaround, I manually put a copy of compiler-rs in ~/.rustup, then I also had to copy libtest, libterm, and libgetopts.

I guess Rust has stopped adding these directories to rust-src? I don't know if that is intentional.

@japaric any thoughts about this?

Apparently the rust-src component has been trimmed down to not contain rustc sources (e.g. librustc). But it seems that a side effect this removed git submodules like compiler-rt and jemalloc which are required to build the std crate. Reported this upstream in rust-lang/rust#41952

As a workaround you can switch to an older nightly version that doesn't have this problem.

I expect xargo to have another bug when sources are OK. But it is overshadowed by this and not easily (without messing with source code directories) reproducible now.

EDIT: Never mind, I did not realize that some features (e.g. "jemalloc") are mandatory.

rust-src is now fixed; it contains all the bits and pieces needed to compile libstd with jemalloc. The problem with the permissions persists; I am working on that one. The fix already given in the README is sufficient.

The following works now:

$ cat Xargo.toml 
[dependencies]
std = {features = ["panic_unwind", "jemalloc"]}
$ cat Cargo.toml 
[package]
name = "miri-xargo"
description = "A dummy project for building libstd with xargo."
version = "0.0.0"

[dependencies]
