soname library native plugins are not copied in Player build

Hello,

We expect that libraries from <project_dir>/Assets/Plugins/Linux/<arch>/ would be copied to <app_name>_Data/Plugins during application build. However only libraries ending with *.so are correctly copied. Libraries having soname structure eg. libtinyxml2.so.6 are not copied, which lead to linking errors.

It seems that Unity Editor does not mark soname libraries as plugins at all. For example their *.meta files do not have "PluginImporter:" tag inside them which is present in *.so.meta files

There are some possible solutions such as copy those files by hand, script or using solution similar to this: https://docs.unity3d.com/Manual/BuildPlayerPipeline.html however those are workarounds.

It seems that Unity should support soname libraries since they are common in Linux environment.

We are currently using Unity 2021.1.7f1

 

Already a bug report for this.

Unity Issue Tracker - Versioned Linux libraries are ignored by the Editor when they are imported (unity3d.com)

Hopefully they will backport this to versions other than 2022.
