WRF4.2.1 compilation Error

[gpavani]

Hi,

I am trying to compile WRF-4.2.1 in Nasa-Unified WRF system using intel compilers and facing error related to multiple definition of a function.
------------------------------------------------------------------------------

Kindly let me know the reason behind the above error. I attached below the compile.log and configure.wrf files.

Thank you,

I would recommend following these steps:
1) First follow along with this [urlhttps://www2.mmm.ucar.edu/wrf/OnLineTutorial/compilation_tutorial.php]compiling tutorial [/url]the best you can - making the necessary modifications for the Intel compiler. For e.g., for Intel the environment settings should be:

export CC=icc
export CXX=icpc
export CFLAGS=”-O3 -xHost -ip -no-prec-div -static-intel”
export CXXFLAGS=”-O3 -xHost -ip -no-prec-div -static-intel”
export F77=ifort
export FC=ifort
export F90=ifort
export FFLAGS=”-O3 -xHost -ip -no-prec-div -static-intel”
export CPP=”icc -E”
export CXXCPP=”icpc -E”

Make sure that your system passes all the tests.

2) Then try to compile the WRF code again - making sure it's a pristine version (no modifications). Issue
./clean -a
export J="-j 1" (this just ensures that it builds with only a single processor - meaning the first error in the compile log is THE error causing the problems)
./configure
./compile em_real >& compile.log

If it's still failing, please attach the new configure.wrf and compile.log files.

Hi,

Thank you for the reply. I tried the compiling wrf after following the steps mentioned above. Still the compilation fails . I attached below the configure.wrf and compile.log files. What was the reason behind the multiple and unndefined errors ?

The errors are

Hi Pavani,
I apologize for the delay. I've not seen this type of error previously, so I wanted to ask the opinion of a software engineer on my team. They aren't quite sure either. I do want to verify that you did a "clean -a" and then reconfigured prior to recompiling the code, correct? You're using Intel V21. We don't have access to that version and haven't been able to test it yet. Do you happen to have access to an older version that you can try - just to see if it's the compiler version causing the problem?

Hi,

Sorry for the late reply.

I did "Clean -a " and then reconfigured followed by recompilation. The error still persists.

I will try compiling with older version of Intel.

Thank you,

Ok, let me know the outcome of that. If you aren't able to compile with an older Intel, could you try GNU, just to help us narrow down whether it's a compiler issue? GNU is free.
