node-rpi-ws281x-native: Build errors on RaspberryPi4

any updates on this PR? I to am having some issue on build.

I think i fixed it, the question is how did it work at all before? This is the diff:

 NODE_MODULE(addon, InitAll)

So GetFunction needed the Nan:: namespace, makes sense.

But some bindings where pointing to non-existing functions (reset and setbrightness), while others where missing. (set*)

Now it compiles and functions in my setup. (raspbian 10 on pi zero with nodejs 14)

Any news? I need to run this on a RPI 3B+

Thanks for your reply @SimonGAndrews

I’ve used NVM to switch to use node 10.21.0 and npm installed the rpi-ws281x package, however it seems running the test I get the same type of error as I did with this ws281x-native:

internal/modules/cjs/loader.js:1208
  return process.dlopen(module, path.toNamespacedPath(filename));
                 ^

Error: The module '/home/pi/test/node_modules/rpi-ws281x/build/Release/rpi-ws281x.node'

NODE_MODULE_VERSION 64. This version of Node.js requires
NODE_MODULE_VERSION 72. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or `npm install`).

Try my fork, I used to have similar issues. https://github.com/lubomirmolin/rpi-ws281x-nodejs
