I have deal ii 7.0 installed on an intel core 2 machine with ubuntu
10.10. I have
gcc 4.4.5
umfpack 4.5.0
When I try to run step 29, I get the following output:
============================ Running step-29

I thought I had built deal ii with umfpack and BLAS. Other examples
work fine.
Thank you for any help.
