[Trilinos-Users] PETSc interface

[Lucie Freret]

Hello All,

I try to apply a Trilinos preconditioner (ML) to a PETSc linear system.
As a first test, I consider the example given in EpetraExt package:
http://trilinos.sandia.gov/packages/docs/dev/packages/epetraext/doc/html/epetraext_petsc_cpp.html

Unfortunately, I can't compile it and get some errors (see below).
I have tried with both petsc-3.4.4 and petsc-3.1.3 (and trilinos 11.4)

It is said here  
(http://trilinos.sandia.gov/packages/docs/dev/packages/epetraext/doc/html/epetraext_petsc_interface.html) that the Epetra_PETScAIJMatrix class was first released with Trilinos 9.0 and  
PETSc-2.3.3

Does anyone already tried to use Petsc interface with older versions  
(of Trilinos and/or PETSc) ?

Thanks,
Lucie
