FWIW I think xilman's post is a more appropriate quote than mine, since I was describing a Kubuntu (Linux) computer. Do you have any advice for us Linux users?

I'm using debian and a GTX 2060 Super.
First you have to get rid of the cub that comes with msieve and use the cub that comes with cuda. On debian I did these commands in the msieve directory:
[CODE]cd cub
rm -rf cub
ln -s /usr/include/cub[/CODE]Then you need the following patch:

For ecm to compile with current CUDA I had to apply this patch:

Thank you, thank you, thank you! They both build now. yafu doesn't build, though. I'll report that to Ben.

I do have the PTX but I still have trouble with the sort_engine...


edit : adding second screenshot

I think that the 1660 Ti needs a different shader model. But I don't know which.

a quick google search tell me it is shader model 6.5... so I should modify the sm_arch to 65?

The CUDA Samples contain a deviceQuery progam. The compile contains these options for CUDA 11.1:

After adjusting the project files to point to my nvidia cuda toolkit location, I just built msieve with compute_75. I have an up-to-date sort_engine.dll and stage1_core_sm75.ptx file. But when trying to run msieve-gpu.exe it gives me this error:

I'm not sure what file it's not finding or where it's not finding it.

My SVN revision is a bit newer, but the solution is the same:
