epetra compilation error

[ajithperera]

trilinos/16.6.0 compilation fails at epetra linear2d_diffusion_pce_nox_sg_solvers.cpp, line 472
#else
det_ML.set("coarse: type","Jacobi");
#endif
Teuchos::RCPNOX::Epetra::LinearSystem det_linsys =
Teuchos::rcp(new NOX::Epetra::LinearSystemStratimikos(
det_printParams, det_lsParams, det_iJac,
det_A, *det_u));

The Error is unexpected type-specifier new NOX (same error appears in lines 647,652,665,690). The compiler is gcc/12.2.0 and openmpi/4.1.6

Any help to fix this greatly appreciated

This is a stokhos example that calls nox. Maybe @etphipp can help?

I am going to guess a configuration corner-case where Stokhos+NOX+Epetra was enabled but maybe Stratimikos wasn't?

@ajithperera are you wanting to use Stokhos? If not, the simplest thing to do would be to disable it by configuring with `-D Trilinos_ENABLE_Stokhos=OFF'. If you are, can you send your configure script to see what you have enabled?

Btw, all of this code will disappear at some point in the near future as Epetra is slated for removal from Trilinos.

Thanks, I will turn off Stokhos. I did not invoke Stratimikos explicitly. Yes, I read about Epetra removal, but deal.ii still needs (even the latest release) Epetra. Thanks again!
