Generally speaking, yes.
If you happen to use deal.II with any of the GPL only derivatives (such

In optimized release mode the `Assert` are reduced to a nnop and will

- we use `Assert(...)` in the library

These two classes are of course just decoration (showing the minimal
interface a vector has to possess). There is usually no need to define
custom V
Hi,
the following example (which is a simplified version of test
lac/linear_operator_01) should get you started. In short: Simply create
an empty LinearOperator object (with the appropriate template
parameters) and populate the corresponding std::function objects.

All,
as you may know, we try to list all publications based on deal.II at
http://dealii.org/publications.html
We use this list to justify the effort we spend on writing this software, both
to our universities as well as the funding agencies that support its
development.

Cross compilation should work - I have briefly tested it back in
2011 and have written a very minimalistic paragraph about what you have
to do:

It would be great if someone could verify that it still works :-D

Dear all,
I had a quick chat with Wolfgang today and we were wondering who else is
attending the SIAM CSE conference in Spokane next week?
Also (in very German tradition) we decided that we absolutely have to
get an informal get-together of users and developers going!
Therefore, let's meet on Tu
Dear all,
Just for documenting this publicly:
An alternative workaround is to simply set
-DDEAL_II_LINKER_FLAGS="-w"
on the command line. This also suppresses the warning (without disabling
lapack and subsequently umfpack).
It would still be nice if we could actually identify the main cause

Correct, -DDEAL_II_FORCE_BUNDLED_THREADS=TRUE does the trick.

My guess is that scalapack was compiled against a different MPI version.
