Berry & Emscripten

[Sebight]

Hello, I am trying to build our codebase (which Berry has implemented) using Emscripten.

The build process itself is fine, but I am getting runtime errors with invalid pointers.

It is coming from this function, and I cannot find why and where is this function called. This function is getting an invalid pointer, for some reason. (Ultimately, it ends up in be_string.c, be_newstr(), where it crashes)

The logs indicate the pointer and the string content.

You can see that the code crashes at the reading of the (invalid pointer) string.

Any idea what could be up? Or maybe prior experience with compiling Berry with Emscripten? I suppose @skiars had to undergo this for the website Berry execution?

Thanks!

I have built it several times without any issue. Did you use this repository ?

Yes. I always start from berry_web when compiling for emscripten. I'm not sure of all differences, but it's always easier to start from a working example. @skiars may provide more information

I see that the port/ files are different. Depending on the platform I'm currently compiling for, I might be able to hot-swap those. I'll try that out.

Happy to get feedback from you on how this evolves

This fixed the entirety of my problem. 😄

Probably not a good practice, but I will test out if it affects anything in my ESP32 environment.
