Hi there,

I’m trying to build the “connect-samples” repository to get started with the examples for implementing a custom live link using the Python

Main Issue:

When I run as described for windows.\repo.bat build I get this error:

>>> Fetching all dependencies.
Package 'msvc' at version '2019-16.11.17-ndebug' is missing from local storage.

I have msvc version 2019-16.11.53 installed and it seems not possible to specify the minor version.

I also tried running .\repo.bat update msvc because I found documentation I understood that that could update package dependencies to the latest version - but that also throws an error.

I would really appreciate, if someone would help me with that -
I’m mainly a python and C# developer with quite limited experience with cpp and building in cpp.

Thanks alread!

Best,
Christoph

The Connect Sample cannot download MSVC anymore via Packman due to a change in security.

However it can be solved by modifying two files, following these steps:

  1. Edit deps\host-deps.packman.xml, you must have the correct VSPro 2019 and MSVC installed:

  1. Run repo build -r (to just build the release version, if you want to build and run the debug version you’ll have to edit both the debug and release version of the next file)
  2. When the previous command fails, edit _build\target-deps\omni_connect_sdk\release\dev\deps\all-deps.packman.xml to remove the msvc and winsdk dependencies:
  1. Run repo build -r again and your samples should now build.

Hi Richard,

firstly thanks the quick helpful response.
I unfortunately do not have access to VS2019, but I do have MSVC 2019 from VS2022 and managed to reference that correctly.

I tried everything as described and got an error after the first run of repo build -r
So I did step 3., removed the msvcand winsdkdependencies and ran repo build -r again, but it still throws an another error about the winsdk version:

I have windsk 10.0.19041.0 and 10.0.22621.0 but I can not get the specific windsk version anymore and I tried to change the .sln project properties as described in the error (set it to generic 10.0)
That is overwritten though when running .\repo build -rand I couldn’t find where it is specified to that.

I would appreciate help with this once again.

Best,
Christoph

Hello,

I managed to install it doing the next steps:
Remove any occurrence of winsdk and msvc dependencies and use your versions you have locally. Also, change their versions in premake.lua to the installed versions you have.

This is from: GitHub - NVIDIA-Omniverse/connect-samples: Samples for the Omniverse Connect SDK that demonstrate consistent and correct USD authoring .

When repo.bat build is run, a version of the Microsoft Visual Studio Compiler and the Windows 10 SDK are downloaded and referenced by the generated Visual Studio projects. If a user wants the projects to use an installed version of Visual Studio 2019 then run repo.bat build --use-devenv. Note, the build scripts are configured to tell premake to generate VS 2019 project files. Some plumbing is required to support other Visual Studio versions.

Hi Armin,

thanks a lot, manage to build it successfully.

As adviced I’ve edited in.\deps\host-deps.packman.xml msvc, winsdk and vc to reference my local dependencies

And then as you adviced I edited msvc_version and winsdk_version in the premake.lua to my local versions.
Thanks again for the help.
