Cargo build error

[maxlein]

I am new to cargo, but following the Readme I get following error and I don't really know how to solve this:

cargo +nightly build --release --all-targets
error: failed to run `rustc` to learn about target-specific information

Caused by:
  process didn't exit successfully: `rustc - --crate-name ___ --print=file-names --crate-type bin --crate-type rlib --crate-type dylib --crate-type cdylib --crate-type staticlib --crate-type proc-macro --print=sysroot --print=cfg` (signal: 11, SIGSEGV: invalid memory reference)

Hi @maxlein ,

Could you please provide the following details:

• What is your platform (architecture + OS) ?
• How did you install Rust and Cargo ?
• If you installed rustup, can you give us the result of command rustup show ?

[maxlein]

Ubuntu 20.04.1 LTS
I installed it like described in the readme and ran the script to install cargo.
I am only using the ros2 version of cyclone v0.7.

Default host: x86_64-unknown-linux-gnu
rustup home:  /home/max/.rustup

installed toolchains
--------------------

stable-x86_64-unknown-linux-gnu (default)
nightly-x86_64-unknown-linux-gnu

active toolchain
----------------

stable-x86_64-unknown-linux-gnu (default)
rustc 1.49.0 (e1884a8e3 2020-12-29)

[JEnoch]

This could be a temporary issue with the rustc compiler in the nightly toolchain from 2020-12-29.
Please run the rustup update command and try to build again.

[kydos]

@maxlein any updates? Please let us know if this is still an issue, and if not perhaps we can close it.

[maxlein]

Just tried again with nightly-x86_64-unknown-linux-gnu updated - rustc 1.52.0-nightly (4f20caa62 2021-03-01) (from rustc 1.51.0-nightly (04caa632d 2021-01-30))

Same error:

cargo +nightly build --release --all-targets
error: failed to run `rustc` to learn about target-specific information

Caused by:
  process didn't exit successfully: `rustc - --crate-name ___ --print=file-names --crate-type bin --crate-type rlib --crate-type dylib --crate-type cdylib --crate-type staticlib --crate-type proc-macro --print=sysroot --print=cfg` (signal: 11, SIGSEGV: invalid memory reference)

[kydos]

@maxlein that looks like an issue in your rust installation or environment setup. Did you source ~/.cargo/env ?

To make sure your rust environment is properly setup try the following:

$ cargo new demo
$ cargo build
$ cargo run
Hello, world!

Let us know what you get.

[maxlein]

Thanks for your help!

I explicitly sourced the environment and I get the same error with above commands:

cargo build
error: failed to run `rustc` to learn about target-specific information

Caused by:
  process didn't exit successfully: `rustc - --crate-name ___ --print=file-names --crate-type bin --crate-type rlib --crate-type dylib --crate-type cdylib --crate-type staticlib --crate-type proc-macro --print=sysroot --print=cfg` (signal: 11, SIGSEGV: invalid memory reference)

@kydos I am getting a separate error than what @maxlein experienced:

Installation

• followed zenoh-plugin-dds README.md

Hi @akila-ganlath,
I think you're missing the llvm-dev and clang-dev packages that are required by cyclors (Rust binding of CycloneDDS). Please let me know if installing those packages solved your issue, and I'll update the README accordingly.

[JEnoch]

Hi @maxlein,

We didn't manage to reproduce the error you get on 20.04.1 LTS.
As far as I understood you also get it outside of the zenoh-plugin-dds project, with the simple Cargo's demo project, right ?

Maybe your issue is similar to rust-lang/rust#80725.
I suggest you look at the backtrace in the dumped core and check if it looks like the one in rust-lang/rust#80725 (comment). If they are similar (i.e. ending in llvm and/or clang) you can try to update or re-install your llvm-dev and clang-dev packages.

If this doesn't solve your issue, you should post a new issue in https://github.com/rust-lang/rust/issues.

@JEnoch , installing clang and llvm-dev via apt allowed me to build and run the demo. Thanks for your help!

Ok, I went this way.
