running tarpaulin in a docker for gitlab-ci

Error

I get the following error on step cargo +nightly tarpaulin --all-features

error: build failed
[ERROR tarpaulin] Failed to compile tests! Error: linking with `cc` failed: exit code: 1

Do you have an example project I could try this out on locally?

Also noted in #525 with an example project https://github.com/rcore-os/zCore/pull/136/checks?check_run_id=962147609 I'm having a look at this today

I got this issue in my pipeline after I update my dependencies.

In that list was: cc It changed from version: version = "1.0.58" To: version = "1.0.59"

After this my project failed to build. Same error as above:

error: could not compile `...`.
To learn more, run the command again with --verbose.
[ERROR tarpaulin] Failed to compile tests! Error: linking with `cc` failed: exit code: 1
Error: "Failed to compile tests! Error: linking with `cc` failed: exit code: 1"

However local GitLab runner (that does not have access to the caches from GitLab) completed without any problems. So knowing this I cleared my caches and restarted the job. (for local cache cleanup use cargo clean) This fixed the problem.

TL;DR: create caches!

So I just tried tarpaulin 0.16.0 on a project with CC that failed with this error, and then my latest one with some linker based changes on it and it worked. I'll be releasing a 0.17.0 this week and would love to hear if this issue is now solved for you all :smile:

@xd009642
Oh, I encountered the same mistake in github-actions. In version 0.17.0 I don't know how to do it.

It suddenly works again today. I don't know what happened to....🐶

For a number of people hopefully once this is closed (cargo PR done by alex) and the next cargo is released this issue should go away https://github.com/rust-lang/cargo/issues/9220

I now have this problem again in another project. It works locally but not on CI. Also tried running docker container locally but could not reproduce it. Although CI consistently fails. I first hit (I think) and infinite loop because my build hit the limit of 60min (usually take about 16min to run CI). But did not get any errors from this.

I updated tarpaulin and nightly versions in container. And now I don't hit time limit anymore but this error. Still works fine locally with exact same docker containers.

I have no idea what causes this to happen. The only think that changes between commits was that I added some more tests. Tests works perfectly fine locally and code was similar to other existing tests.

The error occurs when it is trying to create the binary or at last stage of compiling. (it finished building all crates and maybe also the tests) This makes sense as the error is with the linking.

Nothing special about error message:

   Compiling main v0.2.0 (/workspace/main)
error: could not compile `services`

To learn more, run the command again with --verbose.

Hope this helps in some way, if you need more info, let me know.

Having the same issue with this.

I also stumbled upon this problem trying to generate code coverage for https://github.com/ArekPiekarz/rusty-git-gui, using command cargo tarpaulin.

ArekPiekarz avatar Aug 21 '21 16:08 ArekPiekarz

I had the same issue with cargo-tarpaulin 0.18.0-alpha3 on nightly toolchain (on GitHub actions):

error: could not compile `gpg-tui` due to 2 previous errors
warning: build failed, waiting for other jobs to finish...
error: Broken pipe (os error 32)
error: build failed
Sep 01 23:10:12.542 ERROR cargo_tarpaulin: Failed to compile tests! Error: gpg-tui: linking with `cc` failed: exit status: 1
Error: "Failed to compile tests! Error: gpg-tui: linking with `cc` failed: exit status: 1"
Error: Process completed with exit code 1.

Then I switched to grcov for testing and it revealed that one of the build dependencies was missing:

  = note: /usr/bin/ld: cannot find -lxkbcommon
          collect2: error: ld returned 1 exit status
error: build failed

Solution was adding this build dependency to my CI and voila! "cargo-☔" works as expected.

I wish that the first error message was more clear.

orhun avatar Sep 02 '21 21:09 orhun

@orhun Unfortunately I already had libxkbcommon installed when I tried to run cargo tarpaulin.

With the new version 0.18.2 I get the following end of log:

I guess git2 crate tries to link to libgit2 and fails. I already have installed libgit2, but I also know git2 comes with its own version of it.

@ArekPiekarz

@orhun Unfortunately I already had libxkbcommon installed when I tried to run cargo tarpaulin.

My point was: in my case "something" was missing and cargo-tarpaulin was failing due to that. I used grcov and it revealed the error. Your issue looks the same.

Hmm, interesting. This might be my problem too, but have to test. I got the problem after adding more tests, but might have enabled a feature or something that needed an other lib. This might also explain why it works in my PC but not in CI pipeline.

Thanks for sharing! Will have a look and see if that fixes it.

ralpha avatar Sep 06 '21 20:09 ralpha

Okay took me quite a few hours fixing and testing everything, but I fixed it. Let me explain thing for other people that have similar issues. For initial problems I had see: https://github.com/xd009642/tarpaulin/issues/517#issuecomment-874089885 But I'll summarize below as well.

After checking the issue out again I stumbled on this problem again:

It works locally but not on CI. Also tried running docker container locally but could not reproduce it. Although CI consistently fails. I first hit (I think) and infinite loop because my build hit the limit of 60min (usually take about 16min to run CI). But did not get any errors from this.

Note that before testing I upgraded to cargo-tarpaulin v0.18.2

My CI got stuck while compiling/linking (at end of compiling) but returned no errors. Locally it seemed to work just fine.

After testing I found out that the CI docker container was running out of RAM. This is the reason the compiler (mainly the linker) got stuck. Because when compiling a lot of test modules in parallel it starts multiple linking jobs. Each linking job was using about 2 GB or memory (don't know why, but it did, this was with GNU ld). So 2 GB*8 = 16GB, this was to much for the CI. I switched to the lld (LLVM linker) to see if this fixed the issue, it did change some thing and I fixed some issues with this in the past.

To switch to lld I used: .cargo/config.toml:

[target.x86_64-unknown-linux-gnu]
rustflags = [
    "-C", "link-arg=-fuse-ld=lld",
]

Add this file to the root of your project. So:

my_project
├─ target/..
├─ src or workspace folders
├─ Cargo.toml
└─ .cargo
   └─ cargo.toml

This might solve or create new problems. But could be a way out if you are stuck.

Switching back to ld linker did solve the Broken pipe (os error 32) with cc in this case (I know this did not solve issue in the past, but it did now). I also started the coverage test in a machine with more RAM and after some other fixes I got it working again. :tada:

ralpha avatar Sep 20 '21 23:09 ralpha

There are definitely multiple sources for this issue then. I forgot to post this last week somehow, but it seems like tarpaulin has some issues running in workspaces, which I was able to reproduce (although I don't have the code on the computer I'm using right now).

Noah-Kennedy avatar Sep 20 '21 23:09 Noah-Kennedy

Summary for solving this (and maybe other) issues: These fixes can be used independently. (are in rough order of how best to check)

  1. Clear caches / do a clean build cargo clean https://github.com/xd009642/tarpaulin/issues/517#issuecomment-681194362
  2. Update Tarpaulin, make sure you are running the latest version (there might be an alpha out depending on when you read this) cargo install cargo-tarpaulin to auto update or cargo install cargo-tarpaulin --version 0.18.0-alpha3 to force a particular version.
  3. Make sure you have enough RAM (especially if you are running in CI) https://github.com/xd009642/tarpaulin/issues/517#issuecomment-923429731
  4. Switch to stable or nightly toolchain when possible cargo +nightly tarpaulin
  5. Run with --verbose flag set ( fixed in #787)
  6. Try running less jobs concurrently, use --jobs 2 flag (pick a number less then amount of CPU cores/virtual threads the machine has)
  7. Make sure you are not missing libraries https://github.com/xd009642/tarpaulin/issues/517#issuecomment-912070823
  8. Switch linker ld (GNU, default) or lld (LLVM, see this )
  9. Give grcov a try, this might surface errors that might fix Tarpaulin too. (see below for more info)
  10. ... (there might be more ways to solve this)
grcov test

If all else fails you might be able to find out the problem by trying an other coverage tool. When running grcov it might detect things that will solve problems for Tarpaulin too.

Here are some of the settings I used in order to test things.

export CARGO_INCREMENTAL=0
export RUSTFLAGS="-Zinstrument-coverage -Zprofile -Ccodegen-units=1 -Copt-level=0 -Clink-dead-code -Coverflow-checks=off -Zpanic_abort_tests -Cpanic=abort"
export LLVM_PROFILE_FILE="myapp-%p-%m.profraw"
export RUSTDOCFLAGS="-Cpanic=abort"
export RUSTUP_TOOLCHAIN="nightly"
cargo clean
cargo +nightly build -vv --jobs 4
cargo +nightly test -vv --jobs 4
# or use `-t html` instead
grcov . -s . --binary-path ./target/debug/ -t lcov --branch --ignore-not-existing -o ./lcov.info

# Upload the `lcov.info` file for coverage data ( codecov for example )
./codecov.sh -f ./lcov.info -e CI=true

In my case, my lib referencing an external library, while cargo build succeeds, cargo tarpaulin fails.

My lib.rs:

#[repr(C)]
pub struct PyObject {
    pub ob_refcnt: i32,
}

extern "C" {
    #[cfg_attr(PyPy, link_name = "_PyPy_NoneStruct")]
    static mut _Py_NoneStruct: PyObject;
}

pub unsafe fn Py_None() -> *mut PyObject {
    &mut _Py_NoneStruct
}

Two years after the last reply, I have run into this issue as well. I have tried all steps of @ralpha 's excellent list:

Summary for solving this (and maybe other) issues: These fixes can be used independently. (are in rough order of how best to check)

  1. Clear caches / do a clean build cargo clean Compile error: linking with cc failed #517 (comment)

  3. Make sure you have enough RAM (especially if you are running in CI) Compile error: linking with cc failed #517 (comment)

  4. Switch to stable or nightly toolchain when possible cargo +nightly tarpaulin

  5. Run with --verbose flag set ( fixed in Verbose flag does not display more info #787)

  6. Try running less jobs concurrently, use --jobs 2 flag (pick a number less then amount of CPU cores/virtual threads the machine has)

  7. Make sure you are not missing libraries Compile error: linking with cc failed #517 (comment)

  8. Switch linker ld (GNU, default) or lld (LLVM, see this )

to no avail. My suspicion (from error messages) is a malfunction in combination with insta (and serde?). gcov builds properly, from brief testing.

This one-liner reproduces the issue, and should be stable, as everything is pinned:

Note, if testing such that features using insta are disabled, it works:

42.09% coverage, 226/537 lines covered

The only place where insta is used is here, which isn't built using the above command, as that code is behind #[cfg(feature = "all")] (which is false in the previous).

So I solved it like this:

Quite ugly, but works. The final insta call only checks the test results for correctness, but the code has already been covered by that point. Correctness is checked in regular testing.
