I'm trying to cross compile from x64 to arm64 a simple hello world:
~/test$ cat hello.js
console.log('hello');

but I have the following error:
~/test$ pkg -t node8-linux-arm64 hello.js

pkg@4.3.1
Warning Failed to make bytecode node8-arm64 for file /snapshot/test/hello.js

the resulting binary not start on arm64 board.

Does it works if you try to compile it from the arm64 board?

yes

This is not a problem related to my binary file, this is a know issue. You need the interpreter for the binary file. Check this issue on pkg:

https://github.com/zeit/pkg/issues/310

Check the @Huerlisi answer.

You are using an x64 system so you need to install interpreter for arm64.

Try this:

sudo dpkg --add-architecture arm64

Than try again to compile. Let me know :)

sudo dpkg --add-architecture arm64

this is not sufficient.

I also tried:

sudo apt-get update
sudo apt-get install -y libc6:arm64 libstdc++6:arm64

but these packets aren't available.
So I didn't resolve the problem yet.

If you run file command with node binary you get this output:

/pkg-binaries/arm64$ file fetched-v8.11.3-linux-arm64 
fetched-v8.11.3-linux-arm64: ELF 64-bit LSB shared object, ARM aarch64, version 1 (GNU/Linux), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0, BuildID[sha1]=02bf3444ecc520c4da40e89cbfbf6831e3a205ea, with debug_info, not stripped

As mentioned here to use this binary you need the /lib/ld-linux-aarch64.so.1 interpreter on your device.

Try this tutorial: https://chrislea.com/2018/08/20/cross-compiling-node-js-for-arm-on-ubuntu/ (At the end there is also explained the 64 bit).

In few words:

sudo dpkg --add-architecture arm64
sudo apt install binutils-aarch64-linux-gnu \
> gcc-aarch64-linux-gnu \
> g++-aarch64-linux-gnu

Here you can find another tutorial: http://www.pilotlogic.com/sitejoom/index.php/forum/cross-build-development/3937-cross-compile-from-intel-64-linux-to-arm-64-linux

Remember also that (from https://github.com/zeit/pkg#native-addons):

When a package, that contains a native module, is being installed, the native module is compiled against current system-wide Node.js version. Then, when you compile your project with pkg, pay attention to --target option. You should specify the same Node.js version as your system-wide Node.js to make compiled executable compatible with .node files.

With the script in utils folder in this repo .node files are automatically added to the pkg folder with the executable generated by pkg but you must be sure that you are running the same nodejs version used to compile the pkg bin or the .node files will not work. If nodejs version are different you should use nvm to swith to the same nodejs version and run the comand npm rebuild to rebuild all dependencies with the new version installed. This is not your case because you are compiling a simple project but for other project this problem also could happen.

I also suggest you to use option --debug with pkg to have more details about your error.
