WasmSupport.c:21: undefined reference to `WasmSupport_trap'

[conradlz]

I'm using Ubuntu linux with a recent FStar and kreMLin from master.
When attempting to run: krml -verbose Introduction.fst -no-prefix Introduction -o test.exe && ./test.exe
Where Introduction is the example from the kreMLin tutorial. I get this long error:

⚙ KreMLin auto-detecting tools. Here's what we found:

[msprotz]

try passing -bundle WasmSupport... I'm in the process of rewriting the tutorial to explain how to properly build a project without using kremlin as a compiler driver

thanks for reminding me of this!

[conradlz]

@msprotz Oh wow thank you so much that worked!

I'll leave this open so you can close it when some documentation is updated
