PxSceneDesc.isValid() throws unresolved external symbol

[Freznosis]

I am trying to check if a PxSceneDesc is valid after setting it up with PxSceneDesc.isValid() but it throws an unresolved external symbol error. Seems to not like something about PxgDynamicsMemoryConfig when checking gpuDynamicsConfig.isValid()? Am I missing a certain GPU include?

unresolved external symbol "__declspec(dllimport) public: bool __cdecl physx::PxgDynamicsMemoryConfig::isValid(void)const " (__imp_?isValid@PxgDynamicsMemoryConfig@physx@@QEBA_NXZ) referenced in function "public: class physx::PxScene * __cdecl PxlibWorld::CreatePhysicsScene(void)" (?CreatePhysicsScene@PxlibWorld@@QEAAPEAVPxScene@physx@@XZ)

PhysX 5.1.3 dynamically linked.

The scene desk and gpu mem validation is all in the same header, see here: https://github.com/NVIDIA-Omniverse/PhysX/blob/release/104.2/physx/include/PxSceneDesc.h#L410. Can you try including it?

Yeah I saw that. I tried a lot of different combinations of using/include but could not get it to compile. My next wonder is if PX_SUPPORT_GPU_PHYSX is not being properly defined in the source project? I checked over the source in PxPreprocessor and it seems to be defined properly when building. So I'm at a loss here. Anything else I can check?

Edit: Oh I see PxgDynamicsMemoryConfig is defined whether PX_SUPPORT_GPU_PHYSX is defined or not... well there goes all of my ideas. :)

Edit2: From some more testing. I can use PxgDynamicsMemoryConfig and manipulate it and use it in my project just fine. But as soon as I call isValid() is when the error occurs. Would there be any reason isValid() is not available in a checked build?

Thanks

I'm sorry, I am not sure how I can help further - debugging linker issues is out of the scope of what we can help with.

For future reference or anyone with a similar problem, adding a definition for PX_PHYSX_STATIC_LIB fixed this for me.

Glad you found the issue, @Freznosis - and thanks for reporting back here!
