Hi, all,
I'll jump in here since I wrote the Dendogram class.
Dendogram is not templated; the constructor *is* implemented
in Dendogram.cpp (I can send you the code, if that's needed and
would help diagnose the problem).

It may not be called, but the dynamic linker thinks it needs it anyway. If it works, you could delete the prototype, or if not, you will need to implement the constructor.

I have linked the shared library created from the application which use Trilinos, and I have linked to a lot of Trilinos libraries. From the following error with the undefined symbol. it seems trying to find "KokkosClassic OpenMPNode DefaultHostSparseOps details FirstTouchCRSAllocator". The application I am running used "Kokkos::OpenMPNode" to create Tpetra::CrsMatrix.
