[dune-pdelab] Using gcc4.1 to compile dune-pdelab

[Steffen Müthing]

Hi Jizhou,

as Oliver already told you, PDELab should in theory still work with GCC 4.0, but very few people have
those old compilers available for testing (the oldest I have is GCC 4.2), so your best bet really is upgrading
to GCC 4.3+. That will also help compile times and the quality of the generated code quite a bit because
PDELab will automatically use C++11 features in some of its core data structures.

I'm a little confused about the error, though: The code you posted should be in line 93, not 97:

http://cgit.dune-project.org/repositories/dune-pdelab-howto/tree/src/convection-diffusion/rt0main.cc?id=v1.1.0#n93

Did you use the release packages or have you cloned the repository? Maybe there's some kind of version conflict
between PDELab and the Howto...

Best
Steffen
