[Trilinos-Users] Trilinos build error with gcc-4.6.1

[Perschbacher, Brent M]

Hello John and Martin,
  The issues with gcc 4.6 are known and we have fixed a number of them in
our development branch. Specifically the issue with missing cstddef includes
is a known change for gcc and has been cleaned up in pretty much all
packages. I can't speak for PyTrilinos as our 4.6 testing doesn't currently
build that package(and I don't specifically recall fixing anything in
PyTrilinos), but that is something which I will look into before we release.

John, the EpetraPYTHON_wrap.cpp I'm sure is created by PyTrilinos. I don't
know PyTrilinos or swig all that well, but I've found an Epetra.i file in
pytrilinos/src that looks like it is used by swig to generate an
"EpetraPYTHON_wrap.h", according to the pytrilinos/src/Cmakelists.txt
anyway. I would assume it is also used for or related to generating the
corresponding cpp file as well.

Looks like the generated file,

also needs to be patched.

Can anyone tell me what this
