Can't build with Steamworks SDK

[zh99998]

My project is using Facepunch.Steamworks, which includes a native steam sdk. https://wiki.facepunch.com/steamworks/Installing_For_Unity
It build in my windows server successfully, but script compile phase failed in gameci/editor container.

then Steamworks seems could't be loaded.

what I do is:

docker run --rm -it unityci/editor:2020.3.8f1-linux-il2cpp-0.14 bash

// clone my project
export BUILD_NAME=ExampleProjectName BUILD_TARGET=StandaloneLinux64 UNITY_LICENSE="$(cat ./ci/Unity_lic.ulf)"
chmod +x ./ci/before_script.sh && ./ci/before_script.sh
chmod +x ./ci/build.sh && ./ci/build.sh

I also tried unityci/editor:2020.3.8f1-windows-mono-0.14 and BUILD_TARGET=StandaloneWindows64, same error.

seems it using unity PluginImporter in .meta file to deal with platform-specific things.
in the document:

Unity Config
We have included the Unity .meta files in the zip file, so everything should be set up. The dlls should be assigned to the right platforms and should copy the dlls to the right locations on build.

I wonder the build environment breaks this.

@zh99998 I'm having the same problem. Did you ever solve this?

[bryding]

I solved it. The docker container is running in linux. The Facepunch.Steamworks.Posix dll is pointed at macos instead of linux in the Editor settings. Select this dll in the Unity editor, click the icon corresponding to Editor settings, and switch it from Macos to linux.
