Very usefull.

You chose, Installing the WPS: Enter selection [1-40] : 1 .
What is the difference with option 1 and option 3? On some websites this option is 3.

  1. Linux x86_64, gfortran (serial)
  2. Linux x86_64, gfortran (serial_NO_GRIB2)
  3. Linux x86_64, gfortran (dmpar)

Does it change WRF run speed?

@pratiman-91 utterances

No, it does not affect WRF run speed. The WPS program ungrib do serial operations, while geogrid and metgrid may be run in parallel mode. However, in my experience, the time required to complete a serial or parallel job is almost similar unless you are using a large domain. You can choose either option.

What kind of undefined references?

wrf_io.f undefined reference to nf_inq_vartype
This is one of many undefined references

wrf_io.f undefined reference to nf_inq_vartype

It seems like there is something wrong with your NetCDF installation.

How do I solve that error in NETCDF installation?

I am not sure. Without any error logs. I cannot help.

Hi there,

I successfully installed WRF-4.3.3 in my linux machine. However, I`ve not succeed in built the ungrib.exe file during WPS-4.3.1 compilation. I followed all recommendations posted here, especially that related to the WRF_LIB edition.

So, I would appreciate if somebody guide me on to fix this problem.

What is the error during the compilation of WPS?

@ilms2012 utterances

Hi,

some of the errors I find were:

/usr/bin/ld: cannot find -lg2_4: No such file or directory
/usr/bin/ld: cannot find -ljasper: No such file or directory

dec_jpeg2000.c:5:10: fatal error: jasper/jasper.h: No such file or directory

Hi.
Many thanks for the tutorial. I’ve successfully compiled the WPS, and I’ve got the executables.
However, i'm getting the follow error when a run ungrib.exe

./ungrib.exe
./ungrib.exe: error while loading shared libraries: libjasper.so.4: cannot open shared object file: No such file or directory

Maybe it’s a problem with environment variables, but I guess they are set

echo $JASPERLIB
/opt/jasper-1.900.29/lib/
echo $JASPERINC
/opt/jasper-1.900.29/include/

I would really appreciate if you could give me some hint.
Thank you

@Tiagofcr

For running WPS, you have to add LD_LIBRARY_PATH into your .bashrc.

  1. Open your ~/.bashrc in nano or any other text editor of your choice.
  2. Add this line at the end of the file:
    export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/jasper-1.900.29/lib/
  3. Write and Save edits and then Exit.
  4. Now, in your terminal:
    source ~/.bashrc

Now try to run it. It should work.

@ilms2012

It is my guess that either your jasper compilation is incomplete or you are providing wrong paths for jasper while compiling WPS.

wget https://www.ece.uvic.ca/~frodo/jasper/software/jasper-1.900.29.tar.gz
tar xvf jasper-1.900.29.tar.gz 
cd jasper-1.900.29/
./configure --prefix=/opt/jasper-1.900.29
make
sudo make install

check the library path in the environment

cd WPS-4.2/

export WRF_DIR=../WRF-4.2.1/
export JASPERLIB=/opt/jasper-1.900.29/lib/
export JASPERINC=/opt/jasper-1.900.29/include/

Just a wild guess, try to recompile without changing anything.
Sometimes it works.

@Vitortenorio33 @pratiman-91 did the recommendation work for you as it didn't work for mine or is there an alternative approach to solve the error?

I am unable to replicate this in my system. Just a guess, something is wrong with netcdf linking or installation. Hope it helps!

Dear all, How are you? When I configure the WRF Model on my laptop,I get the error tail -f compile.log /bin/rm -f namelist.input ; cp ../test/em_real/namelist.input . ) Problems building executables, look for errors in the build log .Please help me.

@liltwizzy02

The issue occurs with gfortran 10 and later. i’ll suggest you use a lower version. gfortran 9 installs without the error. (recommended)

Alternatively, you can modify the Makefile, arch/config.defaults and configure files and recompile to solve the error.
for reference: wrf-model/WRF#1251

Hello everyone, I installed version 4.2.1 of WRF with gfortran without problem but i cannot compile the WPS 4.2. he refuses to take out the metgrid.exe file. does anyone know why?

Here is one of the errors:
Fatal Error: Cannot read module file ‘netcdf.mod’ opened at (1), because it was created by a different version of GNU Fortran compilation terminated.

@taguemfo You have to recompile the netcdf with same compiler that you used to compile WRF.
