Hi!

I cannot reproduce. Your example worked out of the box.

Your README says:

bash ./install-ogre-next.sh

But since there was no install-ogre-next.sh I just did the following:

Place OgreNext into third_party/ogre-next
Modify CMakeLists with the following:

diff --git a/CMakeLists.txt b/CMakeLists.txt
index 86508d0..d74c596 100644
--- a/CMakeLists.txt
+++ b/CMakeLists.txt
@@ -23,7 +23,9 @@ endif (LINUX)
 
 
 
-find_package(OGRE 2.3.3 REQUIRED COMPONENTS Bites RTShaderSystem)
+#find_package(OGRE 2.3.3 REQUIRED COMPONENTS Bites RTShaderSystem)
+set(OGRE_INCLUDE_DIRS "/home/matias/hello-ogre-next/third_party/ogre-next/OgreMain/include" "/home/matias/hello-ogre-next/third_party/ogre-next/build/Debug/include")
+set(OGRE_LIBRARIES "/home/matias/hello-ogre-next/third_party/ogre-next/build/Debug/lib/libOgreMain_d.so")
 target_include_directories(${PROJECT_NAME} PRIVATE ${OGRE_INCLUDE_DIRS})
 message(OGRE_LIBRARIES = ${OGRE_LIBRARIES})
 target_link_libraries(${PROJECT_NAME} ${OGRE_LIBRARIES})

And it worked.

It presented a black screen because you were missing the following line in C++:

	compositorManager->addWorkspace( gSceneManager, gOgreWindow->getTexture(), camera, workspaceName,
	                                 true );

[goforbroke1006]

My bad.
To install deps:

bash ./setup.sh

Problem code was in devel branch. Already added to branch main.
The invocation of addWorkspace present, I see blue screen but can't create new scene node - got NULL

[goforbroke1006]

I do next steps:

1. Init ogre root
2. Pull config for render
3. Create window
4. Load resources
5. Register Hlms (a new stuff for me, not sure it is necessary for hello-world)
6. Create scene manager
7. Create camera
8. Create new scene node with OgreHead mesh (already converted to version 2.1)
9. Start rendering loop with window listener

On step 8 got null-pointer.
If bug happens maybe need fix.
If I did not folllow correct order of components initialization could be better got an error like "Create scene node failed: some component were not initialized".

[goforbroke1006]

Without nodes app started ok.

Hi!

The problem is in your CMakeLists.txt setup:

You have the following:

if (CMAKE_BUILD_TYPE STREQUAL "Debug")
    message("Debug mode")
    add_compile_definitions(OGRE_DEBUG_MODE)
endif (CMAKE_BUILD_TYPE STREQUAL "Debug")

Which should be (as suggested by OgrePlatform.h):

if (CMAKE_BUILD_TYPE STREQUAL "Debug")
    message("Debug mode")
    add_compile_definitions(DEBUG)
endif (CMAKE_BUILD_TYPE STREQUAL "Debug")

Otherwise you cause ABI incompatibilities. If you step inside the debugger in createChildSceneNode() call it ends up calling SceneNode::removeAndDestroyAllChildren, which is why your mSceneNode ends up being a nullptr and crashes.

OgreNext 3.0 will come with ABI check tool to early-detect this type of errors.

[darksylinc]

Our CMake bootstrap script uses CMAKE_CXX_FLAGS_DEBUG instead. You can check it for reference if you want.

(See manual for more info on the EmptyProject template).

[goforbroke1006]

Yeah, it's working now. Thanks for help! For me it was a real entry threshold =)

But, before I modified CmakeList file I found "workaround" - I change this

auto *mSceneNode = sceneManager->getRootSceneNode(Ogre::SCENE_DYNAMIC)
            ->createChildSceneNode(Ogre::SCENE_DYNAMIC);

to this

auto *mSceneNode = (Ogre::SceneNode *) sceneManager->getRootSceneNode(Ogre::SCENE_DYNAMIC)
            ->createChild(Ogre::SCENE_DYNAMIC);

and app start without null-pointers.

Did not check with debugger, don't know details.
Just decided to highlight this moment.
