[Trilinos-Users] Python-related compiler warning

[Dustin Langewisch]

Hi all, I'm new to Trilinos, and just recently was able to get it installed
correctly (or so I think). But when I try to compile the
twoD_diffusion_galerkin_example.cpp included with the Stokhos package, my
compiler spits out the warning given below. Everything compiles, and as far
as I can tell everything is working correctly, but the warning is very
annoying and occasionally distracts from actual compilation issues. Does
anyone know how I can fix this issue, or at least how I can make my compiler
stop issuing the warning?

I believe it is Stokhos-related since I haven't seen the message for other
non-Stokhos examples that I've compiled. Also, PyTrilinos seems to be
working, so I don't think it's a python thing despite the various references
to python in the warning.
