Compiling SWIPlCs with Unity WebGL

Help! Predicate
1

Hello everyone,

I am using SWI-Prolog with Unity3D with the SWIPLCS interface and have been able to successfully interact with the swipl engine from my C# scripts.

However, the interaction is working inside the Unity3D Editor as well as when I compile my project (i.e. my game) for Windows (using the Mono compiler) but not when I compile my project for WebGL (using the Il2CPP compiler). In the last case, I get the following errors :

    ERROR:root:compiler frontend failed to generate LLVM bitcode, halting

From what I have understood, the compiler has issues translating the C++ code from the SWIPLCS interface.

Any idea how to solve this? Thanks
