I've had a similar problem with C++ addons. In one instance I had to change
libraries ('iltorb' compression library) and in the other I had to use
emscripten to transpile the C++ code into javascript so the V8 engine could
use directly. It doesn't feel like a solution as much as a workaround, but
it does work.
