Hey

I am facing certain errors while compiling WRF ARWpost. I have successfully configured the same but while compiling I have issues.

ARWpost is very tricky to get to work. Since it is no longer support (as far as I know) you have to manually change stuff to get it to work.
@Prachi Are you familiar with python at all?

Yes, i am. i am well versed in pyhton but using windows operator.
If you could guide me how to proceed, i will follow.

Since I am stuck at the last stage of installation, any leads will be highly appreciated.

@Prachi it's midnight here in the states. I will do it first thing in the morning. Simple changes but I already shut down the PC with the installation code I have done.

 

[Prachi]

oh okay.
What would I have to do after you share the code.
Please guide in step wise process for easy installation.
Thanks.

@Prachi

Good morning


I would encourage you to explore wrf-python as well as it is where NCAR is heading for post/pre processing of WRF.

However this is the steps to fix ARWpost.

1. Navigate to the ARWpost folder where you extracted the files from the tar file.

cd  /path/to/ARWpost

2. run a clean command to remove all pre configured settings

./clean -a

3. you sed command to change these strings in the Makefile for ARWpost

sed -i -e 's/-lnetcdf/-lnetcdff -lnetcdf/g' /path/to/your/ARWpost/src/Makefile

4. Make sure you export the NETCDF Director where netcdf files are installed. Not NETCDF-C and NETCDF-Fortran need to be in the same folder

export NETCDF=/path/to/netcdf/folder/

5. run the configure command for ARWpost

./configure

6. If you are using GNU (gcc/gfortran/g++) version greater than 10.0.0 then you need the following sed statement

 sed -i '32s/-ffree-form -O -fno-second-underscore -fconvert=big-endian -frecord-marker=4/-ffree-form -O -fno-second-underscore -fconvert=big-endian -frecord-marker=4 ${fallow_argument} /g'  /path/to/ARWpost/configure.arwp

7. Change the order of flags in ARWpost configure file

sed -i -e 's/-C -P -traditional/-P -traditional/g' $WRF_FOLDER/ARWpost/configure.arwp

8. Run the compile command

./compile

9. Export the ARWpost.exe to $PATH

 export PATH=$WRF_FOLDER/ARWpost/ARWpost.exe:$PATH

That should help you.

There is no sed command in the makefile in src folder.
Can you help me locate the same.

@Prachi

sed command is a terminal command, that you use so you don't have to manually change the files.

@Prachi

sed command is a terminal command, that you use so you don't have to manually change the files.

Otherwise you have to search the whole file to manually edit them.

In 7th point, what does WRF_Folder refers to

In 7th point, what does WRF_Folder refers to

sorry that would be /path/to/ARWpost

 

[Prachi]

sorry that would be /path/to/ARWpost

yes, i did try but it is not working ..same error

 

[Deleted member 3607]

sorry that would be /path/to/ARWpost

that would be the path to the folder where arwpost is being built.

 

[Deleted member 3607]

yes, i did try but it is not working ..same error

so it would be something like this on my machine

/path/to/ARWpost ----> /home/workhorse/Build_WRF/ARWpost

 

[Prachi]

Yes, understood. followed the command lines but same error persists, rank mismatch and makefile error

 

[Deleted member 3607]

so it would be something like this on my machine

/path/to/ARWpost ----> /home/workhorse/Build_WRF/ARWpost

its the absolute file path for your system. Since I don't know what your system setup is the convention for writing it out would be /path/to/your/files/example.file.sh

 

[Deleted member 3607]

I made a mistake.

I put an argument into # 6.

it should be this

 sed -i '32s/-ffree-form -O -fno-second-underscore -fconvert=big-endian -frecord-marker=4/-ffree-form -O -fno-second-underscore -fconvert=big-endian -frecord-marker=4 -fallow-argument-mismatch /g'  /path/to/ARWpost/configure.arwp

do you mean makefile.sh and configure.arwp.sh

@Prachi I apologize I copied the code directly from my install code, so I forgot that I have exports preset in my bashrc file.

do i need to use.sh or try with revised code once

 

[Deleted member 3607]

do you mean makefile.sh and configure.arwp.sh

'/home/workhorse/WRF_Intel/ARWpost/configure.arwp'
'/home/workhorse/WRF_Intel/ARWpost/src/Makefile'
