Vive flow build guide?

[dmikushin]

Hello, thank you for all your hard work on Wolvic!

I have a difficulty following your instructions about building for HTC Vive.

1. Firstly, this link in README -> VIVE Developer Resources <- refers to an empty WordPress site. What does it mean?
2. Instruction states to download the VIVE Wave SDK, but it's not clear what to download: Unreal Engine, Unity, native SDK. Which one to download?
3. VIVE website mentions the latest SDK is not supported on Vive Flow:

This version has a known issue NOT working on Vive Focus(+) and Vive Flow . Please use the previous version(5.0.3 or former) on these Vive devices. We are fixing this compatibility issue and target to fix in next SDK release.

However, the archive of older versions is empty. So how do you obtain Vive Wave SDK to compile Wolvic for Vive Flow?

So the situation with HTC devices is the following, currently there are no partners supporting the maintenance and development of the HTC port. This means that, given the scarce resources we have, we basically cannot maintain it. We're open to integrate external contributions if there are people willing to maintain it though.

PS: the SDK we use for any port is always the native one.

Hi @svillar , thank you for this explanation. Do you still have the build scripts for HTC devices, or CI or a Dockerfile? I understand that may not be maintained atm, but do they exist in principle?

There is a flavour in gradle for the wavevr backend, but I insist is heavily unmaintained (I barely remember someone mentioning that it was only working with rather old WaveVR SDK releases)

Hi @svillar , I've install Wolvic on HTC Vive Flow just yesterday. Do you remember when was the last release of Wolvic for this platform?

We have never released Wolvic for HTC. You might try early versions of Wolvic 0.9.x, maybe they still work...

Hmm - interested in seeing if this can get picked up and made active by HTC. Will see what can be done.

HTC has the "Vive Browser" on the XR Elite, which looks like an old Firefox Reality. But you can also download Wolvic v 1.3.2 from March. If y'all aren't building this, is HTC?

I've been wanting to build Wolvic for a while, and just bought an XR Elite (used) to play with it. I'm really looking forward to seeing a Chromium-based web engine (or Webkit next year), hoping Meta has contributed some of the good work they did on the Meta browser into Chromium so you guys can leverage it

We are definitely not building anything for HTC. They haven't been interested in supporting the development of Wolvic so far, so we had to devote our scarce resources to the platforms of our partners.

Patches are very welcomed 😄

Hi there, I am basically at the same issue like @blairmacintyre toying around with an XR Elite. The instructions on the main/README.md mention as second step https://github.com/Igalia/wolvic-third-parties.git which seemingly doesn't exist? Are there any updated instruction which I have missed? Well, reading on cleared it for me. Please put upfront that these instructions are only for Igalia in-house.

I managed to build the latest Wolvic 1.6.1 with WaveVR Native SDK 3.2.0 using the patched Gecko as described in the guide. Everything builds fine - after a few struggles. The issue that I have now is that on device the app crashes with

Looks like the wavevr SDK classes are missing from the dex files, any ideas what I might need to do to get it bundled correctly. I'm not really an Android developer but I have a rough idea. Thanks

[svillar]

Not really. Is that a release build? If so maybe there are proguard rules preventing some symbols from being accessible

[azw413]

It was a release build and that was a good suggestion but com.htc.* is already excluded in the proguard file. It's also the same error on a Debug build. I notice that I need to be building the wavevrStore version which appears to have the correct icon size for the Viveport library. Incidentally for anybody following in my footsteps, I could only get Gecko to build locally (required for WebXR patches) on an Intel Linux machine and not on a M1 Mac.

I got a little further and have successfully built Wolvic 1.6.1 with wavesdk 4.5.0 and it deploys and runs! However, there's no input so you can't interact with the app. I had a quick look through the code and can't see anything obviously missing, just wondered if anybody else might have any idea what to look at.
