[Wrf-users] WRF Compilation Error

[Andy Porter]

Hello,
>
> I'm having an issue compiling WRF V3.1.1 with the Intel compilers using a multi-processor (dmpar) build.  NCAR Graphics (6.0.0) and NetCDF (4.1.3) are also built with the Intel compilers. The configure.wrf file contents (minus comments) and a list of the environmental variables are shown at the end of this message.  The following is the first of several warning/undefined reference messages:

I have successfully built WRF and WPS on this system before, but this is the first time I have tried it with everything compiled with icc and ifort.  Any suggestions would be much appreciated.

That looks like either netcdf has not been built with Fortran support or 
there's an issue with how the compiler has named its objects. I've not 
had trouble with the Intel compiler and the latter issue so I suspect 
the former - I think the configure flag you want for netcdf is --enable-f90.

HTH,

Andy.
