Examples do not build #1419

TomMD · 2020-09-13T23:19:58Z

Describe the bug
The examples in rules_haskell do not build.

To Reproduce
On my OS-X machine

git clone https://github.com/tweag/rules_haskell
cd rules_haskell/examples
bazel build //cat_hs/exec/cat_hs

And observe

ERROR: /private/tmp/rules_haskell/examples/cat_hs/exec/cat_hs/BUILD.bazel:6:15 HaskellCabalLibrary @stackage//:unliftio-core failed (Exit 1) cabal_wrapper failed: error executing command bazel-out/host/bin/external/rules_haskell/haskell/cabal_wrapper lib:unliftio-core unliftio-core-0.1.2.0 true external/stackage/unliftio-core-0.1.2.0/Setup.hs external/stackage/unliftio-core-0.1.2.0 ...

INFO: 20 processes: 20 darwin-sandbox.
FAILED: Build did NOT complete successfully

Expected behavior
I thought this would build a binary that could be run.

Environment

OS name + version: OS-X with bazel 3.14 from brew.
Bazel version: 3.14
Version of the rules: This was on git rev aabeedc

Additional context
Add any other context about the problem here.

I also tried on linux:

docker run --rm -it ubuntu:20.04 bash
# follow bazel instructions here https://docs.bazel.build/versions/master/install-ubuntu.html
apt update && apt install -y git
git clone https://github.com/tweag/rules_haskell
cd rules_haskell/examples
bazel build //cat_hs/exec/cat_hs

The latter looks like an instance of #1416. Regarding macOS, could you run again with --verbose_failures?

TomMD · 2020-09-20T22:17:26Z

On linux with python 3 the problem now looks much more manageable (mismatched hashes):

If/when the bug is fixed at least for Linux, would you accept a PR that adds building these examples to the CI via a gitlab action or similar?

Profpatsch · 2020-09-28T17:58:24Z

would you accept a PR that adds building these examples to the CI via a gitlab action or similar?

We are always open to PRs (especially improving examples/documentation/testsuites!).
Our CI is built run with buildkite (https://buildkite.com/tweag-1/rules-haskell) and CircleCI (for MacOS https://app.circleci.com/pipelines/github/tweag/rules_haskell).

aherrmann · 2020-09-29T07:18:22Z

It's worth pointing out that the examples and tutorial are tested on CI in nixpkgs mode. However, they are not currently tested in bindist mode.

timoffex · 2021-02-07T07:05:41Z

Are there any workarounds for the DEVELOPER_DIR issue on OS-X? I tried setting BAZEL_USER_CPP_ONLY_TOOLCHAIN=1, made sure DEVELOPER_DIR wasn't empty (but it was empty for me before... what is it even?), and did a bazel clean before retrying. None of that seemed to change anything.

$ echo $DEVELOPER_DIR
/Applications/Xcode.app/Contents/Developer
$ echo $BAZEL_USER_CPP_ONLY_TOOLCHAIN
1
$ bazel --version
bazel 3.3.1-homebrew
$ bazel clean && bazel build //cat_hs/exec/cat_hs
<some text and eventually the "DEVELOPER_DIR not set" error>

I'm on macOS Catalina (Version 10.15.4).

TomMD · 2021-02-13T23:10:58Z

@timoffex I think we need to consider bazel Haskell unmaintained for the non-nix case, there aren't CI tests or interested parties at this point.

The developer dir is actually a clang concept, observe:

$ DEVELOPER_DIR=foo clang
xcrun: error: missing DEVELOPER_DIR path: foo

I've tried adding export DEVELOPER_DIR=... to my .profile and rc but haven't had any impact so whatever is setting the environment isn't playing nice.

aherrmann · 2021-02-15T11:05:28Z

We do run tests on CI for the macOS bindist use case. However, they currently do not include the example or tutorial. The main test suite and the start script on the other hand are tested on CI in the macOS bindist configuration and are expected to work.

As the example is currently only tested in a Nix configuration, it is possible that the some of the Nix provided toolchains collide with the standard toolchains in the non-Nix use-case. To test this, you could remove all the nixpkgs_* calls in the example's WORKSPACE and see if this helps.

We are working on unifying the CI setup, we've recently ported Linux and macOS to both use GH actions and are also working on covering more tests in all configurations. Unfortunately, we gotten to the examples, yet.

tanyabouman · 2021-04-09T16:14:31Z

I reproduced the part of the problem that occurs on Ubuntu:

docker run --rm -it ubuntu:20.04 bash
# follow bazel instructions here https://docs.bazel.build/versions/master/install-ubuntu.html
apt update && apt install -y git
apt update && apt install -y python3
git clone https://github.com/tweag/rules_haskell
cd rules_haskell/examples
bazel build --verbose_failures //cat_hs/exec/cat_hs

and fixed it with

apt update && apt install -y build-essential libffi-dev libgmp-dev libtinfo5 libtinfo-dev python python3

since those are required dependencies.

However, it would be really nice if the error was a little more friendly than the current mess, so I will investigate that.
