[Trilinos-Users] [EXTERNAL] Not able to load shared library, undefined symbol in Trilinos

[Bill Spotz]

So I get the following:

$ c++filt __ZN9DendogramC1EiiiRN7Teuchos3RCPIN6Tpetra9CrsMatrixIdiiN13KokkosClassic10OpenMPNodeENS4_20DefaultHostSparseOpsIviS5_NS4_7details22FirstTouchCRSAllocatorEEEEEEEii

Dendogram::Dendogram(int, int, int, Teuchos::RCP<Tpetra::CrsMatrix<double, int, int, KokkosClassic::OpenMPNode, KokkosClassic::DefaultHostSparseOps<void, int, KokkosClassic::OpenMPNode, KokkosClassic::details::FirstTouchCRSAllocator> > >&, int, int)

It looks to me like a Dendogram constructor (which I assume is on your side, as it is not a Trilinos class I am aware of) is defined in a header but not implemented.  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.
