cross compiling isn't cross compiling on host=linux-x64, target=linux-arm64

Filed this but they routed me here. As alluded to there, prebuildify is generating an x64 .so even with the --arch arm arg. Here's the line in their workflow:

run: npm x -- prebuildify --strip --arch arm64 --target 20.9.0 

I've also manually run prebuildify-cross using that command line but with -i linux-arm64 as well, and still ended up with an x64 .so. Hoping it's just me or something about the my setup locally. has anyone cross compiled linux-arm64 prebuilds?

If not, any idea where to look for the problem? I kinda expect the next place is node-gyp, but I'm hoping to avoid that if possible ;) I'm willing to find/fix the problem but a little help at identifying the layer to focus on would be super helpful.

Out of the box, prebuildify doesn't cross-compile, and you were right to look at prebuildify-cross.

has anyone cross compiled linux-arm64 prebuilds?

Yes, classic-level has 'em, serialport too I believe.

perfect. I'll see if I can figure out differences between them and tree-sitter 👍

Turns out we just had to set CC & CXX for node-gyp because prebuildify doesn't do it automatically.
