Immediately Terminates with "'rustc --print target-list' failed"

[pr0me]

Hey,

after installing cross, any attempt on using it for building terminates with

$ cross build --target armv7-unknown-linux-gnueabihf --verbose
error: `"rustc" "--print" "target-list"` failed with exit code: Some(1)
   0: error_chain::backtrace::imp::InternalBacktrace::new
   1: <std::process::Command as cross::extensions::CommandExt>::status_result
   2: <std::process::Command as cross::extensions::CommandExt>::run_and_get_stdout
   3: cross::main
   4: std::sys_common::backtrace::__rust_begin_short_backtrace
   5: main
   6: __libc_start_main
   7: _start

I tested this for different programs and different targets.

My environment:

cross 0.2.1
cargo 1.51.0-nightly (ab64d1393 2021-02-10)

# my local rustc
rustc 1.52.0-nightly (5fa22fe6f 2021-02-14)
rustup 1.23.1 (3df2264a9 2020-11-30)

docker 20.10.1
runc 1.0.0-rc92

Any idea on how to fix this is appreciated, thanks.

Also getting this error. Not really sure where to go from here.

[uber-alles-code]

Having the same issue...

[ondrowan]

The same thing started to happen with Rust 1.54.0 and target armv7-unknown-linux-gnueabihf. It works with 1.52.1 and 1.53.0.

[dbischof90]

Has this been resolved? I'm getting this error as well:

$ sudo cross build --target armv7-unknown-linux-gnueabihf
error: `"rustc" "--print" "target-list"` failed with exit code: Some(1)
note: run with `RUST_BACKTRACE=1` for a backtrace

[Emilgardis]

@dbischof90 can you please add -vv to the arguments for debug output? Also what version of cross are tou using?

[dbischof90]

Rowing back - I think I solved at least my case.

I had to add my user to the docker usergroup and run it without sudo, that seemed to make the difference!

EDIT: my cross setup is

$ cross -V
cross 0.2.1
cargo 1.59.0 (49d8809dc 2022-02-10)

and I run on Arch. But that seems to be unrelated here. With -vv I see that

[...]
+ "/usr/bin/docker" "run" "--userns" "host" "-e" "PKG_CONFIG_ALLOW_CROSS=1" "--rm" "--user" "1000:1000" "-e" "XARGO_HOME=/xargo" "-e" "CARGO_HOME=/cargo" "-e" "CARGO_TARGET_DIR=/target" "-e" "USER=daniel" "-e" "CROSS_RUNNER=" "-v" "/home/daniel/.xargo:/xargo:Z" "-v" "/home/daniel/.cargo:/cargo:Z" "-v" "/cargo/bin" "-v" "/home/daniel/Programming/Rust/helloworld:/project:Z" "-v" "/home/daniel/.rustup/toolchains/stable-x86_64-unknown-linux-gnu:/rust:Z,ro" "-v" "/home/daniel/Programming/Rust/helloworld/target:/target:Z" "-w" "/project" "-i" "-t" "rustembedded/cross:armv7-unknown-linux-gnueabihf-0.2.1" "sh" "-c" "PATH=$PATH:/rust/bin cargo build --target armv7-unknown-linux-gnueabihf -vv"
[...]

so it needs my username as input which might not be accessible if called through sudo. Is that possible?

[Alexhuszagh]

This command should be running on the host, and therefore shouldn't be affected by whether or not Docker is invoked or not.

cross/src/lib.rs

Line 279 in d90b016

let target_list = rustc::target_list(false)?;

This failing suggests something odd is happening with your system. Can you report the output of:

# we don't care about stdout, just the error output and exit code
$ rustc --print target-list >/dev/null
$ echo $?

This should give 0, indicating success, but something tells me on your systems it's not.

I've tried this on x86_64-unknown-linux-gnu and with the following toolchain versions:

• rustc 1.52.0-nightly (8e54a2113 2021-02-13)
• rustc 1.59.0 (9d1b2106e 2022-02-23)
• rustc 1.61.0 (fe5b13d68 2022-05-18)
• rustc 1.63.0-nightly (5435ed691 2022-06-07)

I've tried both the 0.2.1 release and cross built from main. This suggests to me it's probably not an issue in cross or the rust version but an issue in the installed rust toolchain.

tl;dr rustc --print target-list is returning a non-zero exit code, suggesting it's failed, which is causing cross to fail.

[Alexhuszagh]

This no longer reproduces it seems. I've got verbose output information from cross v0.2.2 running with those specific toolchains, on an x86_64-unknown-linux-gnu host. This might an issue if you haven't installed some dependencies to run cargo or other Rust binaries, such as libgcc.

If there are still issues, I'll re-open this.

So, I'm running into this.

$ rustc --print target-list >/dev/null
$ echo $?

Would print 0.

But the build would fail on getting the target list:
