support Node.JS v12

[Rong Shen]

It worked when I was trying to build node.js v6.5.0 but failed with node.js v12.40.0

The part of the output is following:

I encountered the same issue and from my understanding now, its becuase bytecode_builtins_list_generator is not compiled for the host system

There you go:

I am facing the same issue while cross-compiling nodejs version 13.1.0. Above changes are already there in configure.py, it is still not working though, bytecode_builtins_list_generator is getting compiled for the target machine, can someone please help here.

[Julian Dropmann]

Its probably due to this change in v13.0.1: nodejs/node#30021
Either reverse that change or build with snapshots: termux/termux-packages#4762

[SwatiSonam]

Thanks for your prompt response. I tried compiling using --with-snapshots flag, still stuck with same issue (bytecode_builtins_list_generator is getting built for target machine). Could you please suggest something here?

[Julian Dropmann]

If you want to compile node 13 I think it would be easier to just revert this change: nodejs/node@2623ef0 and compile --without-snapshot (as long they did not any further conflicting changes). If you want to make snapshots work with cross-compiling you might want to take a closer look how termux did this, or maybe just use their binaries. I have not done this, I am still on node v12 for my android project. I would be interested in a solution once LTS switches to 14.

[SwatiSonam]

Thanks a lot for all your help and suggestions. I am able to compile nodejs 13.0 using the steps mentioned in link - https://chrislea.com/2018/08/20/cross-compiling-node-js-for-arm-on-ubuntu/

Can you please share the version 13 compiles? arm and arm64?

Thank you greatly!
