[petsc-users] slepc NHEP error

[Kannan, Ramakrishnan]

Can I use CHKERRV instead of CHKERRQ? Will that help?

          Why do you have the CHKERRQ(ierr); commented out in your code? 
        
           Because of this you are getting mangled confusing error messages. 
        
           Put a ierr = in front of all calls and a CHKERRQ(ierr); after each call. 
        
           Then resend the new error message which will be much clearer.
