[Wien] "bc: Command not found" - problem in Wien2k_18

[Dr. K. Balamurugan]

Dear Wien2k developer and users,

I recently installed Wien2k_18 (the latest version) on openSUSE 15.0.  
While, I tested using TiC as a case example; I got the following as an  
output of SCF run:

-------------------------------
etest: Subscript out of range.
bc: Command not found.
bc: Command not found.
bc: Command not found.
bc: Command not found.
bc: Command not found.
bc: Command not found.
  MIXER END
  CORE  END
bc: Command not found.
  LAPW2 END
  LAPW1 END
  LAPW0 END
------------------------------

The "bc. Command not found" appeared in response to the "x sgroup" run.

Please help me to solve the problem; why the SCF calculations could  
not be completed?

Thanks.

With regards
Dr. K.Balamurugan
