CMake Error at src/CMakeLists.txt:4 (find_package):
Could not find a configuration file for package "OpenXR" that is compatible
with requested version "1.0.34".

The following configuration files were considered but not accepted:

D:/msys64_QtQGisAll/mingw64/lib/cmake/openxr/OpenXRConfig.cmake, version: 1.0.27

is this project support only for 1.0.34 version or minimum version required 1.0
now current version of openXR is 1.1.53

Hi. As per commit ddda53f, at least OpenXR 1.0.34 SDK is required at build time in order to build support for XR_EXT_user_presence extension, and it should be safe to just use the latest SDK.
At runtime it should work with older and newer OpenXR versions too. It will try OpenXR 1.1, fall back to 1.0, and should adapt to the presence of absence of optional extensions (if it doesn't it may well be a bug)

since we are developing vr feature in our application

1. is this project is compatible with mingw compiler?
2. support quest3 with steam VR?

I would expect so though I haven't tried it. It works woth gcc and win32 though.

2. support quest3 with steam VR?

Others have had it working on quest, and I test with SteamVR on linux.

yes , its support gcc compile now, i compiled without any errors, but in future development consider writing compiler specific codes too, gcc is quite different than msvc (eg, macros declaration) ,

and need more example code on api usage in docs

[amalon]

msvc should work too (a stable version of osgXR is built on windows as part of flightgear CI).

Yes there's not a lot of example code at the moment. I develop it in my spare time primarily for FlightGear (which doesn't make a concise example). The headers & comments in include/ are the main API documentation.

im using meta quest 3 with steam vr, connected device to steam vr and tried the example code the osg viewer is loading and loading the teapot , but no reaction from the vr side and its not printing any debugs

can you tell me , what are the pre requirements and setup

[amalon]

There are environment variables required for the teapot example:

Basically OSGXR=1

Its recommended to use the Manager class to control VR from your app though, as for anything non trivial you'll want more control
