From what I see the version 2.0.0.4.116 is already in LibreELEC repo.
But what is strange that it has same bug:
Code
08:06:47.563 T:139834346896704 ERROR: AddOnLog: ScummVM: Unable to load: /storage/.kodi/addons/game.libretro.scummvm/game.libretro.scummvm.so: undefined symbol: _ZN3GUI13OptionsDialog5cleanEv
Also size of the library is much different: mine is >30MB, from LE repo ~2MB.
Will investigate later what is going on. Maybe it is be LE addon build environment .
