Just tried it using Zorin OS (based on Ubuntu 20.04), didn't work either, essentially the same error with a slightly more verbose output :

Also tried building from source on Windows 10, and also got some "-O3" error.

EDIT : Just realized my Linux setup doesn't have a proper GPU. That might be the case for the original issue as well.
That being said, I still get a similar output when trying to build on my Windows setup, which does have a GPU with proper drivers and CUDA installed.

bodono · 2021-11-16T14:59:21Z

@BptGrm The errors about missing #include <cublas_v2.h> are when you don't have cuda installed on your system, or if it is installed then the location of the headers is not in the path environment variable (eg C_INCLUDE_PATH).

@1359347500cwc Your error is about missing #include "scs_matrix.h" which is very strange as that should be included with the scs files. Does it only happen when trying to build the gpu version?

@BptGrm The errors about missing #include <cublas_v2.h> are when you don't have cuda installed on your system, or if it is installed then the location of the headers is not in the path environment variable (eg C_INCLUDE_PATH).

Seems obvious now that you mention it, sorry about that.
On that matter, is building scs_gpu from source compatible with a conda-installed CUDA, or do I need to have a "standalone" install on the computer ?

bodono · 2021-11-18T12:30:47Z

I think it should be compatible so long as you tell it where the header files and the cuda binaries are. If you run into problems just open an issue.

@BptGrm When I execute command： python setup.py install --scs --gpu，The same problem was encountered . Have you finally solved this problem？

b-grimaud · 2022-01-03T08:08:14Z

@zhonglinliu123 Make sure you have CUDA installed, in my case it was directly in the conda environment, but I think a standalone install should work
