Cannot get CUB to compile with nsight on CUDA 9.1

Developer Tools Nsight Eclipse Edition
1

Hello - First time posting.

I’m trying to go through the example program given on CUB here: CUB: example_block_radix_sort.cu

Following the instructions at: https://nvlabs.github.io/cub/#sec6

  1. I created a project in nsight
  2. Added the CUB files in a directory in the project.
  3. Added the cub folder to my include path flag

The compiler seems to find all the includes correctly. However, I get the error

Method 'SortBlockedToStriped' could not be resolved. Line 118

This is from the line of code:

BlockRadixSortT(temp_storage.sort).SortBlockedToStriped(items);

I’m kind of at a loss since this is based on their example code and I followed their instructions. Am I missing something in the project setup? I checked the block_radix_sort.cuh file and saw that the method is defined. Not sure why it won’t compile. Any help is appreciated. Thanks so much!

EDIT

Here’s my console output:

The console output seems to be fine and the it shows the project was successfully built. Where is the compiler error?

Hm, I guess it’s really an nsight error and not a compiler error. I tried running the code and got an expected output. The error is listed under the problems tab down at the bottom. I guess I will ignore that for now. Any idea how to make that go away?

Try to run the indexer again. Right click on the project-> Indexer → Rebuild.
