Error when compiling InstRecLib #47

Hi, I want to use your project but I face some problems now, and I really need help. :(

  1. Before compiling DynSLAM project, I compile InstRecLib and get these errors:

/home/imlab-slam/DynSLAM-master/src/DynSLAM/InstRecLib/InstanceReconstructor.cpp: In member function ‘void instreclib::reconstruction::InstanceReconstructor::SaveObjectToMesh(int, const string&)’: /home/imlab-slam/DynSLAM-master/src/DynSLAM/InstRecLib/InstanceReconstructor.cpp:750:30: error: expected type-specifier before ‘ITMMeshingEngine_CUDA’ auto *meshing_engine = new ITMMeshingEngine_CUDA<ITMVoxel, ITMVoxelIndex> ( ^ /home/imlab-slam/DynSLAM-master/src/DynSLAM/InstRecLib/InstanceReconstructor.cpp:763:10: error: type ‘’ argument given to ‘delete’, expected pointer delete meshing_engine; ^ make[2]: [CMakeFiles/InstRecLib.dir/InstanceReconstructor.cpp.o] Error 1 make[1]: [CMakeFiles/InstRecLib.dir/all] Error 2 make: *** [all] Error 2

I think the problem is that in InstanceReconstructor.cpp, there is no include related to ITMMeshingEngine_CUDA, so I just include it like this:

include ITMMeshingEngine_CUDA.h

  1. After include ITMMeshingEngine_CUDA.h file, I got another errors: /home/imlab-slam/DynSLAM-master/src/DynSLAM/InstRecLib/../../InfiniTAM/InfiniTAM/ITMLib/Engine/DeviceSpecific/CUDA/ITMMeshingEngine_CUDA.h:48:9: error: ‘ global ’ does not name a type global void findAllocatedBlocks(Vector4s *visibleBlockGlobalPos,

and I also search for the solution... and found that terms related to CUDA(e.g. globlal in ITMMeshingEngine_CUDA.h) are not allowed in .cpp files, which is a compiler issue.

Because I am a beginner of CUDA, I really don't know how to solve this problem. Can anyone help me please? really thanks!

Hi wj4y78308, and thanks for checking out the project!

I believe that the reason you are seeing the second error is because you are including a CUDA-specific implementation in a cpp file which should be platform-agnostic.

The first error looks like a compiler version mismatch. What version of g++ are you using, and what operating system are you on?

Thank you for replying me! I alreadly solved this problem :)

That's great to hear! Can you describe your solution briefly, in case someone else experiences a similar problem in the future? Thank you!
