Hello!
I have just tried to compile DOFLIN on a CentOS5.5 (RHEL5) server, and it is
almost there. However I get these warnings, which becomes errors:
FiniteElement.h
---------------

/home/hake/local/src/dolfin/dolfin/fem/FiniteElement.h:35: warning: ‘class
dolfin::FiniteElement’ has virtual functions but non-virtual destructor

The first one is easy to fix, but I wonder why the compiler has start
complaining about that now. The other warning is just weird. Since when is it
not good practice to iterate over an unsigned variable. And why is it not
complaining elsewhere? Something to do with openmp? Not sure which version of
openmp it is on the server...
The version of g++ is 4.1.2.
