macoy, in case that helps
I am integrating Bullet3 Physics into the Ogre renderer in Windows. At the moment I am trying to get the frameStarted function working.
It kinda works in the sense that I am able to printf and move a mesh but after a second or so the application doesn't respond.

Has anyone managed to successfully link ogre libraries after building it statically on Windows?
I successfully built both 1.12.10 from source and also tried this with 1.12.9 from vcpkg. I'm working on a crossplatform solution so using CMake/writing CMakeLists rather than visual studio tooling. I'm trying to compile the same code as from the bootstrap tutorial, so I'm doingfind_package(OGRE REQUIRED COMPONENTS Bites RTShaderSystem)
and latertarget_link_libraries(0_Bootstrap OgreBites OgreRTShaderSystem)
Trying to run this gets me lots of errors similar to Target "0_Bootstrap" links to target "SDL2::SDL2" but the target was not
found., indicating the dependencies are not linked correctly. (SDL2, ZLib, and Imgui are some of the libs in question that error)
if I manually resolve them by doing a find_package(SDL2) and all the other missing packages, it still errors upon compilation. the command that fails is C:\...link.exe ...stuff... obj /out:src\0_Bootstrap.exe ...various.lib_files_being_linked... freetype.lib ...other.lib_files...
which naturally isn't surprising because the linker has no idea where freetype.lib is. This seems odd though, seeing as how the find_package(OGRE) stuff should've handled all the includes and libraries for me. I spent a while hacking at doing it without find_package and copying what the generated OgreTargets.cmake file did, but it was tedious and sifting through the undefined references was painful.
Is this a bug or am I missing something glaringly simple?

AttributeError: module 'cv2.cv2' has no attribute 'ovis. I have opencv-contrib-python installed, so I thought I am good to go? In the article it says that ovis is an OpenCV module.
Any ideas?

I'm also trying to get this tutorial to work: https://www.ogre3d.org/2020/12/24/augmented-reality-made-simple-with-ogre-and-opencv
I'm trying to use docker for it. I first build opencv from source on ubuntu:20.04, to get ovis enabled I added:apt install libogre-1.12 libogre-1.12-dev, ARG OGRE_DIR=/usr/share/OGRE/cmake/modules/, touch /usr/lib/x86_64-linux-gnu/libOgreGLSupport.a. It builds fine, I can access it in opencv.
However when I run: owin = cv2.ovis.createWindow("VR", (800,600)), I got a bunch of errors about missing zip files in /usr/share/OGRE/Media/packs/, so I downloaded all the missing files for the packs folder. Now I'm getting errors:
owin = cv2.ovis.createWindow("VR", (800,600))

I've tried downloading the content that goes in /usr/share/OGRE/Media/volumeTerrain/, but it still can't load the zip even though I can see it. Do I need to use an older version of libogre?

Ogre::CompositorManager2::createBasicWorkspaceDef(), but the window stays white. I'm getting my nVidia FPS counter so I assume there is some rendering going on at least.
Problem
I'm so sorry to ask the stupid question.I can't find any document about "ogre java binding".
so i wrote a java tutorial application referenced from BasicTutorial.cpp.
i will be very appreciated,if any advice
Code
test.java

inputListener=new InputListener();
sceneManager=applicationContext.getRoot().createSceneManager();
shaderGenerator=ShaderGenerator.getSingleton();
light=sceneManager.createLight("MainLight");
lightNode=sceneManager.getRootSceneNode().createChildSceneNode();
camera=sceneManager.createCamera("mycam");
cameraNode=sceneManager.getRootSceneNode().createChildSceneNode();
}
public void setup(){
init();
applicationContext.initApp();
applicationContext.addInputListener(inputListener);
shaderGenerator.addSceneManager(sceneManager);
sceneManager.setAmbientLight(new ColourValue(0.5f,0.5f,0.5f));
lightNode.attachObject(light);
lightNode.setPosition(20f,80f,50f);
camera.setNearClipDistance(5f);
camera.setAutoAspectRatio(true);
cameraNode.attachObject(camera);
cameraNode.setPosition(0f,0f,140f);
applicationContext.getRenderWindow().addViewport(camera);
}
public void run(){

applicationContext.closeApp();
}catch (Exception exception){

this is trivial to do with a render_quad compositor
Doesn't sound like it can be solved with simple render_quad compositor unless I'm missing something. If I understand correctly _createRenderWindow forces the resolution that Ogre uses for rendering the scene and no matter what value I give for target_width_scaled for the compositor, it will be scaled back to the size of the RenderWindow created.
