Build and package errors as per kit-app-template

[darien.wei]

Hi there,

we are trying to build and package kit APP, on ubuntu 22.04, as per template GitHub - NVIDIA-Omniverse/kit-app-template: Omniverse Kit App Template, but got two problems:
• Build miss some files (repo.sh: not found), but seems success finally
• Package fail due to missing PACKAGE-LICENSES file

Cloud you give some clues/ideas that may cause these?
Thank you.

Hi @darien.wei. We have a new version of the app template coming out soon. This may end up being a non-issue then, but I’ll get the team to look at this just in case.

[darien.wei]

Hi Mati,

Thanks for the reply.
Is any update on this issue? and when will you deliver the new template?

Regards,
Darien

Hey @mati-nvidia ,

thanks for all the great videos about Kit App Template.

Unfortunately build.bat doesn’t seem to find my installed and running Omniverse USD Composer 2023.1.1.
It gives me these errors:

In repo.toml, is the name of the app still “create” since the change of the foundation apps names?
I’ve tried my luck randomly with other strings like ‘composer’, or ‘usd_composer’, etc. But No luck.

I’m stuck at the very first step! I’ve also tried disabling entirely Windows’ firewall, still no luck. I’m a Tech Artist not a Dev, so, I’m sure I’m missing something obvious out ; ) Any idea? Cheers!

I have also been trying to use the Kit app template, but it is not working with USD Composer (can’t find Omniverse extensions in a custom extension). It also seems that Omniverse Launcher v1.8.11 broke the configuration. It cannot find the installed apps (v1.8.7 was working fine). I raised an issue on GitHub:

USD Composer · Issue #5 · NVIDIA-Omniverse/kit-app-template (github.com)

[mati-nvidia]

@_stef @dvelazco Please hang tight. The new app template is coming and will work differently. It will no longer require a “baseapp” to link against. If you want to continue working with the current app template, please stick with the Kit 104.2-based apps (e.g. USD Composer 2022.3) for now.

@dvelazco Let me know if you’re still having issues with Launcher 1.8.11, but linking against Composer 2022.3. This will be a non-issue with the new app template, but curious if something did change in the Launcher.

[dvelazco]

Thanks for the update. Looking forward to the updated template!

Yes, I have not been able to build the app since Launcher 1.8.11. You can reproduce this by simply cloning the kit-app-template and running the build.bat script (while having Launcher 1.8.11 installed). My coworker did not do the update and is able to build our custom app as usual.

[dvelazco]

Hello @mati-nvidia, do you know of a way to install an earlier version of Omniverse Launcher? I am still having issues with v1.8.11. Thanks in advanced.

[mati-nvidia]

Hey all. Thanks for your patience. The new template for building apps is here! GitHub - NVIDIA-Omniverse/kit-project-template: A template for developing apps and extensions for Omniverse Kit

[lily.chen]

Hi @mati-nvidia,
Why I run an example app that includes example extensions by “./source/apps/my_name.my_app.sh (linux).”, there is no helloworld extension window pop up ? (I can see it shows up for only 0.01 second and then disappear, the second screenshot is the warning I have got)

Here is the log in the console:

Thanks for your help in advance!!

By the way, kindly remind you that there have an error in the document.

[dvelazco]

Thanks Mati! Giving it a try. I noticed this is a different repository. Is the kit-app-template just for legacy purposes now?

[mati-nvidia]

@lily.chen Thanks for the heads up. I’ve let a developer know about the documentation typo and the issue you ran into.

@dvelazco Yes. This is the new repo you want to use and the other one is legacy at this point.

[dvelazco]

Moving things over smoothly so far, thanks for the update! If I may ask though, what is the process of compiling a C++ extension?

[darien.wei]

Hello @mati-nvidia

I got the same issue as Lily’s, which hello world extension popup and closed in no time.
Upload a screen video for your investigation.

Thanks and regards,
Darien

[darien.wei]

Hi @mati-nvidia

Thanks for your effort.

But one question needs your clarification.
If we take a new template to develop and package it into a new APP. Does it mean there is no need to install Omniverse Launcher and Omniverse APP like Create, Isaac Sim in the Production Machine, but required to execute pull_kit_kernel.sh only after we copy the package zip file to the Production Machine?

Thanks and Regards,
Darien
