Dear Drs. Simon and Wolfgang,
Thank you very much for your kind explanation.
Due to your helps, the problem is solved. However, the other problem
happens...
When I run the step-6 example, there is no problem at all. But, when I run
the step-29 exmaple which includes the direct solver, the following error
message appears...
CMake Error at CMakeLists.txt:41 (MESSAGE):
Error! The deal.II library found at /home/hanks318/deal_II/dealii_830 was
not configured with
DEAL_II_WITH_UMFPACK = ON

tutorial step.

As Dr. Wolfgang mentioned, do I have to change the version of compiler...?
If you don't mind, could you please let me know how to downgrade the
version of complier...?
Thank you in advance.
Kyusik.
