Have you solved your problem？
I have the same problem as you，and I am not able to solve it.
If you have saved it,can you teach me?

Hi, not sure if you still care, but I also stumbled upon this problem. What worked for me was opening the file "include/conjugrad.h" and simply commenting out the offending line by adding // in front of it.
