MacOS build fails with unity-builder but not with unity-test-runner ?

[achimmihca]

Bug description

• my StandaloneLinux64 build fails with GitHub Actions
• It does not fail on my local machine
• Other targetPlatforms also do not fail with GitHub Actions, although there is no platform specific code.
• Running same project with unity-test-runner for StandaloneLinux64 also does not fail. But a true compiler error should fail the build (I think ?)
• Log says "Error building Player because scripts had compiler errors", but it does not tell me, in which file the the compiler error occurs.
• Log says a lot "/bin/sh: 1: mktemp: not found", maybe this is related?

How to reproduce

• Happens when I run the unity-builder on https://github.com/UltraStar-Deluxe/Play/actions
• Please find the configuration here: https://github.com/UltraStar-Deluxe/Play/blob/master/.github/workflows/build-unity-project.yml
  • As I said, this unity-test-runner works: https://github.com/UltraStar-Deluxe/Play/blob/master/.github/workflows/test-unity-project.yml

Expected behavior

The build should be consistent with the unity-test-runner build - and should not fail.

I don't know how I should debug this issue.
Is there a parameter I can set to get more log output from unity-builder?

Please find the log output here: https://github.com/UltraStar-Deluxe/Play/runs/4033610940?check_suite_focus=true

EDIT: Sorry, can you view the GitHub Actions log? I am unsure if only contributors can view it...

You have 77 errors that all say the same thing: /bin/sh: 1: mktemp: not found.

I've not seen this error before in other peoples projects. Perhaps it's related to https://github.com/UltraStar-Deluxe/Play/runs/4033610940?check_suite_focus=true#step:5:1637 or some code before it.

At first sight this doesn't look to be a bug in unity-builder, but lets find out.

It does not fail on my local machine

As a first step, could you please verify this statement by creating a fresh clone of your project and building your project from it, without performing steps that also do not happen in your CI?

I upgraded the project to Unity 2021.2.0f1.

The good news is that the Linux build is working now.
The bad news is that now the MacOS build is failing.
It is similar to before, but now with mac. However, there are different log outputs of course.

Anyway,

• The MacOS build works with the unity-test-runner.
  • https://github.com/UltraStar-Deluxe/Play/actions/runs/1400508769
• The MacOS build works on my local machine (building on Windows for MacOS).

I am again bit lost on this, because I am not a MacOS user.
Please, find the log here: https://github.com/UltraStar-Deluxe/Play/runs/4050822575?check_suite_focus=true

Any ideas?

I am also unable to build my minimal test project: https://github.com/achimmihca/UnityTestProject
Please find the log here: https://github.com/achimmihca/UnityTestProject/runs/4055552640?check_suite_focus=true

I removed the space in the project's name to see if this is causing the issue. But the build still fails.
However, the build on my local machine works fine (for macOS as well as iOS)

Maybe its an issue with the new Unity 2021.2 version?
I think the output location of Unity's build artifact is slightly different than in 2021.1

Could it be some issue related to Burst? I see these in your logs:
https://github.com/achimmihca/UnityTestProject/runs/4055552669?check_suite_focus=true#step:7:2472
https://github.com/achimmihca/UnityTestProject/runs/4055552640?check_suite_focus=true#step:7:3068

I'd recommend using Linux laptop (or VM) to try building your project.

Also getting issues building for macOS on 2021.2. No issues for Linux and Windows builds.
We're using Burst 1.6.1.

Here are some errors, not sure if they're the cause though. I couldn't find much else in the logs that was concerning though.

@MaxwellDexter
Have you tried using your personal Linux laptop or VM to build the macOS version?
I think that would be the first place to start debugging this error.

Looks like this issue is actually a duplicate of #320, which should be fixed soon by game-ci/docker#158
