[Moderator note: The original title was: "/opt/intel/Compiler/11.1/073/include/math.h:27:3: error: #error "This Intel <math.h>"]

While compiling OpenFOAM with Icc (defined in /etc/cshrc file) following type of error is produced:

/usr/include/c++/4.3.2/type_traits(82): error: expected a ">"
struct is_rvalue_reference<_Tp&&>
^

I am getting this error while doing ./Allwmake in OpenFOAM project directory.
I am installing in HPC cluster with SUSE Enterprise OS, of which ~/.cshrc file is presented below:

set path=($path /opt/pbs/default/bin $HOME/bin)
source /usr/share/modules/init/tcsh
module load mpt/2.01
module load intel_11.1.073
#setenv BOOST_ARCH_PATH $HOME/boost/1_62_0


setenv FOAM_SETTINGS 'WM_NCOMPPROCS=4 WM_MPLIB=OPENMPI WM_ARCH_OPTION=64'
alias of230 'source $HOME/OpenFOAM/OpenFOAM-2.3.0/etc/cshrc $FOAM_SETTINGS'
#setenv of230 source $HOME/OpenFOAM/OpenFOAM-2.3.0/etc/cshrc $FOAM_SETTINGS
#source $HOME/OpenFOAM/OpenFOAM-2.3.0/etc/cshrc $FOAM_SETTINGS
#source $HOME/OpenFOAM/OpenFOAM-2.3.0/etc/cshrc

#set WM_COMPILER="Icc"
alias of230 'source \/home1/rsoni/OpenFOAM/OpenFOAM-2.3.0/etc/cshrc WM_NCOMPPROCS=4 WM_MPLIB=OPENMPI WM_ARCH_OPTION=64'

These are after some attempts to modify it to support foam installation.

I have struggled a lot over internet about troubleshooting but no luck. Can be anybody please help me how to resolve. How to prevent Foam using intel include files especially math.h

Further, details regarding system are as follows:

cat /proc/version

Ok, got it solved partially.
The key is with the source with following switch:

-U__GXX_EXPERIMENTAL_CXX0X__

The files inside $WM_PROJECT_DIR/wmake/rules define the compilation controls and switches. What we need to do is to identify our system configuration i.e. architecture and compiler and then enter into appropriate directory and modify the c++ to append above switch.

Example for my case:
uname -m

x86_64

echo $WM_ARCH

Since, it is problem of Icc I modified /linux64Icc/c++

So the c++FLAGS lines look like

c++FLAGS    = $(GFLAGS) $(c++WARN) $(c++OPT) $(c++DBUG) $(ptFLAGS) $(LIB_HEADER_DIRS) -fPIC -U__GXX_EXPERIMENTAL_CXX0X__
