rust overlay: no such file or directory

[sjmackenzie]

Expected behaviour:

Rust nightly is downloaded and run without a problem

Actual behaivour

Rust nightly fails with this error:

Steps to reproduce

install rust rightly using this repository.

Are you on NixOS?

It looks like the install.sh script needs to be patched to correct the bash path.

[sjmackenzie]

Yes I'm on NixOS.

Has an upstream path changed to break the build, I'm pretty certain it's not me.

I'm running into this issue as well. For me, on NixOS 17.09.git.b50193f, the derivation continues to build just fine but the interpreter is not patched.

#  Cargo and other Rust binaries are available in my PATH
$ which cargo
/run/current-system/sw/bin/cargo

# But they can't be executed
$ cargo --version
bash: /run/current-system/sw/bin/cargo: No such file or directory

# Because the interpreter isn't patched
$ readelf -l $(which cargo) | grep interpreter
      [Requesting program interpreter: /lib64/ld-linux-x86-64.so.2]

EDIT: Actually, the problem I'm running into on is different from this one. For me, install.sh is being patched just fine. When building, I'm getting the following warning instead:-

setting interpreter of /nix/store/1lmb3xdl6bj47v31j2livjyqib21ci0a-rust-1.22.0-nightly-2017-09-09-ddd123ed9/lib/libstd-85c630e4370fa944.
so
cat: /nix/store/zgzak0grvimifrxr3yww1xbyix0qyrv8-gcc-wrapper-6.4.0/nix-support/dynamic-linker: No such file or directory

This is because dynamic-linker no longer exists:-

$ ls /nix/store/zgzak0grvimifrxr3yww1xbyix0qyrv8-gcc-wrapper-6.4.0/nix-support/
add-flags.sh      cc-cflags   libc-cflags  orig-libc      propagated-native-build-inputs  utils.sh
add-hardening.sh  cc-ldflags  orig-cc      orig-libc-dev  setup-hook

I don't have time to look deeply into it so here are some pointers:

There is already an attempt to patch the install script at https://github.com/mozilla/nixpkgs-mozilla/blob/master/rust-overlay.nix#L173, maybe the location of the script has changed?

I would also recommend submitting the change to rust-lang to always use #!/usr/bin/env bash for the shebang so we don't have to patch it in the first place.

@rushmorem try updating your rev to 7e54fb37cd177e6d83e4e2b7d3e3b03bd6de0e0f (current master head). It worked for me. If it works for you I'll close the issue.

[rushmorem]

@sjmackenzie I will, thanks. Also, according to NixOS/nixpkgs#29278 (comment) that should work so feel free to close.

EDIT: Just to clarify, I was already this repo's latest rev (7e54fb3). What I needed to update was my NixOS version.
