WebRTC does not support arm64 architecture.

I'm getting this error when executing the cli:

Could you upload log of this command?

$ npm install @noia-network/node-cli -g --verbose

[franciscorubin]

Here it is:

[MartynasZilinskas]

What is your: Node.js, npm, OS versions?

[franciscorubin]

Node: v8.11.3 npm: 5.6.0

OS: Distributor ID: Ubuntu Description: Ubuntu 16.04.1 LTS Release: 16.04 Codename: xenial

[MartynasZilinskas]

I recommend upgrading Node.js to v9.1.1 and reinstall node-cli.

[franciscorubin]

@MartynasZilinskas I just tried with that version, but no luck... Exact same error :(

Are you running 32 or 64 bit? The error log might mean that it couldn't find prebuild wrtc module which is compatible with your system, so it couldn't download it. So module not found error was thrown. WRTC support source (https://github.com/js-platform/node-webrtc):

	x86	x64	arm	arm64
Linux		✔︎
macOS		✔︎
Windows		✔︎

[franciscorubin]

Oh, I see. I'm running it on a Pine64 (https://www.pine64.org). It's arm64. So does it mean that my device is incompatible or is there any workarounds?

[Dancia]

To explain it properly I will have to give more details.

NOIA Node CLI and NOIA Node GUI need wrtc module to run WebRTC in desktop environment. The problem is that this wrtc module is native, which means that it has to be compiled to run with a particular processor (such as an Intel x86-class processor) and its set of instructions. In your case it's arm64 processor.

In standard case NOIA Node determines what processor given machine has and tries to download particular binary for given OS/processor/else. Currently wrtc in its repository doesn't have prebuild binaries for arm64 processor, so your installation fails.

does it mean that my device is incompatible

It's not that it's not compatible, it's just that there's no ready to use prebuild binaries for your machine. The solution would be to compile it itself, but you have to be power user to do it, since it might be to complicated for regular users! There is discussion pretty much about it here: https://github.com/js-platform/node-webrtc/issues/388

So there are three possible paths we can take from here:

1. Hope that wrtc module will start hosting binaries for arm64 and other popular processors too.
2. Users could build it themselves completely on their own.
3. NOIA could try to built it and host somewhere or write some instructions or help improve wrtc (https://github.com/js-platform/node-webrtc) so users know how to build it.

There's a lot of things in our roadmap, this one is not listed, but if many people will face the same issue, we will put more man hours into trying to solve this issue!

Appendinx npm install when it fails to download and compile

When you run npm install, you might see something like this:

404 status code downloading tarball https://node-webrtc.s3.amazonaws.com/wrtc/v0.1.6/Release/node-v57-linux-arm.tar.gz

So it tries to compile it itself and since the machine is missing some configuration and libraries to tell NodeJs how to compile it:

Unable to install a pre-built wrtc binary; falling back to ncmake
Running ncmake configure
CMake binary could not be found. Please verify your PATH.
Running ncmake build

, well... nothing happens, so You end up without wrtc library.

Please let me know if my answer helped.
