Thank you for reporting the issue. We are aware of the problem and the discussion is active about possible solutions.

We are in the midst of converting the MAGMA repository from mercurial to git, which we hope to complete on June 15th. All the known issues will be copied to the new git repository.

I’ve been able to track down the issue to the deprecated and now missing `cusparseSolveAnalysisInfo` function call, which most things in sparse seem to rely upon. Is there a strategy in place to move to something else?
