[Dune] How to force -std=c++0x in a dune project?

[Arya Fallahi]

Dear Dune support team,

I am still elaborating to install my dune project on a linux server and I
have still problems. The problem is however this time very strange for me.

On machine 1 with operating system ubuntu the following packages are
installed:
automake 1.11.2
autoconf    2.68
libtool        2.4.2
openmpi   1.6.1
ALUGrid    1.52
dune-common rev. 7127
dune-geometry rev. 375
dune-grid rev. 8798
dune-istl rev. 1789
gcc           4.7.1

On this machine my dune code runs perfectly.

On machine 2 with operating system scientific linux the following packages
are installed:
automake 1.13
autoconf    2.69
libtool        2.4.2
openmpi   1.6.3
ALUGrid    1.52
dune-common rev. 7127
dune-geometry rev. 375
dune-grid rev. 8798
dune-istl rev. 1789
gcc           4.7.2

However, the same dune code returns an error for this system (the dune
modules compile perfectly), which is partly as follows:

if g++ -DHAVE_CONFIG_H -I. -I. -I..  -I/afs/

        then mv -f ".deps/dgtd-dgtd.Tpo" ".deps/dgtd-dgtd.Po"; else rm -f
".deps/dgtd-dgtd.Tpo"; exit 1; fi

new behavior (and get rid of this warning), build your Dune with
--enable-fieldvector-size-is-method. If you do need the vector size as an
enum, use 'dimension'.

This seems to be due to the incorrect standard chosen for this machine. In
the first line "g++" should be "g++ -std=c++0x" as in machine 1. I googled
and searched throughout the Dune Build howto to find the way to set this in
the opts file. However, I could not find any thing. My opt file is pretty
simple:

CONFIGURE_FLAGS="    MPICC='/tools/openmpi-1.6.3/bin/mpicc'
                                       CXXFLAGS='-O3 -g0
--no-strict-aliasing'
                                       CPPFLAGS='-O3 -g0
--no-strict-aliasing'
                                       --enable-parallel
                                       --prefix='/tools/cyrus'
                                       --with-metis='/tools/metis-5.0.2'

--with-alugrid='/tools/ALUGrid-1.52'    "

I tried adding "-std=c++0x" to the CXXFLAGS but it prevents the other
dune-modules to compile. My question is do you know the correct way to
force the c++0x standard for compiling the code?

Thank you in advance for your assistance and best regards,
Arya
