(RESOLVED) (WRF dm+sm): referencia a `__kmpc_dispatch_next_4' sin definir

[JCollins]

Hi all.

I am compiling the WRF with (dm+sm) and using Intel compilers. The compilation ends correctly. When compiling WPS (serial) only ungrib.exe is generated. The geogrid and metgrid executables are missing. The same thing does not happen to me when I compile WRF with (dmpar), since WPS compiles correctly.

I also did a test with WRF with (smpar) and I have the same problem as with (dm+sm).

Did the same thing happen to someone?

Hi,
Can you please attach the following:
configure.wrf
configure.wps
compile log for WPS

Thanks,
Kelly

Hi.

I attach the files.

Thanks.

Hi,
Thanks for sending those. The error you are getting during the WPS compile is due to the fact that you compiled WRF with the dm+sm option, and since the geogrid and metgrid programs make use of the I/O from the WRF compile, they are trying to link against the I/O for dm+sm and they need some OpenMP information. Try the following:

1) ./clean -a
2) reconfigure
3) open up the configure.wps file and modify the 'WRF_LIB' line from:

WRF_LIB         =       -L$(WRF_DIR)/external/io_grib1 -lio_grib1 \
                        -L$(WRF_DIR)/external/io_grib_share -lio_grib_share \
                        -L$(WRF_DIR)/external/io_int -lwrfio_int \
                        -L$(WRF_DIR)/external/io_netcdf -lwrfio_nf \
                        -L$(NETCDF)/lib -lnetcdff -lnetcdf

to (adding the ending part - which should be correct for an Intel compiler):

WRF_LIB         =       -L$(WRF_DIR)/external/io_grib1 -lio_grib1 \
                        -L$(WRF_DIR)/external/io_grib_share -lio_grib_share \
                        -L$(WRF_DIR)/external/io_int -lwrfio_int \
                        -L$(WRF_DIR)/external/io_netcdf -lwrfio_nf \
                        -L$(NETCDF)/lib -lnetcdff -lnetcdf -liomp5 -lpthread

4) save the configure.wps file and recompile.

Let me know if that makes a difference.

Hi.

Great, that modification solved the error.

Thank you very much for your help.

 

[kwerner]

Great! Thank you for letting me know.

 

[Jayanti pal]

what about gfortran compiler ?
I am facing the same issue

 

[kwerner]

Hi Jayanti,
For gfortran, you should follow the same procedure as above, but instead, add
-lgomp
So it should look like:

WRF_LIB         =       -L$(WRF_DIR)/external/io_grib1 -lio_grib1 \
                        -L$(WRF_DIR)/external/io_grib_share -lio_grib_share \
                        -L$(WRF_DIR)/external/io_int -lwrfio_int \
                        -L$(WRF_DIR)/external/io_netcdf -lwrfio_nf \
                        -L$(NETCDF)/lib -lnetcdff -lnetcdf -lgomp
