• [X] I have checked the release documentation and the latest documentation (for main branch).

Steps to reproduce the issue

I first cloned Open3D by:

git clone https://github.com/isl-org/Open3D.git
cd Open3D

Then, I build Open3D (on Windows 11 with VS2022, latest MSVC, with CUDA 12.4) with:

mkdir build
cd build
cmake -DBUILD_SHARED_LIBS=OFF -DBUILD_CUDA_MODULE=ON -DBUILD_WEBRTC=OFF ..
# Then Open Visual Studio 2022 and build Open3D (or just the stdgpu target).

Error message

[13/148] Performing configure step for 'ext_stdgpu'
  CMake Error at cmake/Findthrust.cmake:17 (math):

Open3D, Python and System information

- Operating system: Windows 11 64-bit
- Python version: not applicable
- Open3D version: latest main (8 Apr 2024)
- System architecture: x64
- Is this a remote workstation?: no
- How did you install Open3D?: build from source
- Compiler version (if built from source): Microsoft (R) C/C++ Optimizing Compiler Version 19.39.33523 for x64

Additional information

This error occurs because cmake/Findthrust.cmake extracts the Thrust version from Thrust's header file. In CUDA 12.3 (and presumably earlier), the line in the Thrust header looks like:

#define THRUST_VERSION 200200

And in CUDA 12.4 it is:

#define THRUST_VERSION 200301 // macro expansion with ## requires this to be a single value

Thus, CMake's regexp in cmake/Findthrust.cmake fails as it encounters the unexpected trailing comment on that line.

Author of stdgpu here. This has been fixed upstream in https://github.com/stotko/stdgpu/pull/408, so updating the dependency in Open3D should fix it there as well.

Hi @stotko, do you mean we need to update this file: https://github.com/isl-org/Open3D/blob/main/3rdparty/stdgpu/stdgpu.cmake

@stotko Hi and thank you for the reply here, that's great!

@manhha1402 Yes I believe that is exactly what would need to be done in the Open3D repo - update the commit hash in that cmake file.

Sadly with the last stdgpu version Open3D seems to be incompatible. It shows errors like:

#13 247.4 /opt/Open3D/build/stdgpu/include/stdgpu/impl/unordered_base_detail.cuh(1230): error: a value of type "cuda::std::__4::pair<const open3d::utility::MiniVec<int64_t, 1>, open3d::core::buf_index_t> *" cannot be assigned to an entity of type "stdgpu::pair<const open3d::utility::MiniVec<int64_t, 1>, open3d::core::buf_index_t> *"
#13 247.4       result._values = allocator_traits<allocator_type>::allocate(result._allocator, total_count);

Sadly with the last stdgpu version Open3D seems to be incompatible. It shows errors like:

#13 247.4 /opt/Open3D/build/stdgpu/include/stdgpu/impl/unordered_base_detail.cuh(1230): error: a value of type "cuda::std::__4::pair<const open3d::utility::MiniVec<int64_t, 1>, open3d::core::buf_index_t> *" cannot be assigned to an entity of type "stdgpu::pair<const open3d::utility::MiniVec<int64_t, 1>, open3d::core::buf_index_t> *"
#13 247.4       result._values = allocator_traits<allocator_type>::allocate(result._allocator, total_count);

The incompatibility stems from the recent change in stdgpu to move to a custom implementation of pair instead of pointing to thrust::pair which resolves some namespace issues, see https://github.com/stotko/stdgpu/pull/425.

Adapting Open3D to that change should mostly reduce to replace thrust::pair by the intended stdgpu::pair here: https://github.com/isl-org/Open3D/blob/f4e1fa94f6b8385092eaddc721d6dfe9799f9a68/cpp/open3d/core/hashmap/CUDA/StdGPUHashBackend.h#L93 https://github.com/isl-org/Open3D/blob/f4e1fa94f6b8385092eaddc721d6dfe9799f9a68/cpp/open3d/core/hashmap/CUDA/StdGPUHashBackend.h#L255

@stotko I applied your changes and now I can compile and install Open3d with stdgpu. However, the OnlineSLAMRGBD example does not work. It shows the initial windows but when it fails when touching the resume/pause button and starts integrating.

I ran the example, compiled in RelWithDebInfo inside WinDbg, and it shows this stack trace:
