Issue when compiling WW3

[NS-Nik]

Hi!

I was following the Manual step by step and faced a problem on the compilation stage (Section 5.7)

When I am running the w3_automake or w3_make commands I get the same mistake:

A couple of things:
Do you have required libraries like compiler, netcdf, mpi? loaded in your envirorment?
Did you do model/bin/setup ./model -c , so proper link and comp files are generated in you model/bin?
Do you have a switch in your model/bin directory?

You also can use cmake to compile to code, see cmake Readme

I have all necessary libraries and linked netcdf library.

The environment was set up via w3_setup command:
./model/bin/w3_setup model -c intel -s Ifremer1

comp, link and switch files are in the right directories.

Hi @NS-Nik, I'm facing with the same problem. Could you please share how did you fix it?

I also ran into issues using the w3_automake script. The cmake method worked though. From the root directory, run this:

mkdir build  
cd build  
cmake ..  
make  

I did have a build fail with ubuntu 24.04. It works in 22.04. Something changed in gcc or gfortran between those releases.

Hi @gonesurfing, are you able to run regression tests after this installation? Could you please help me with this?

[mickaelaccensi]

@NS-Nik , you should use run_cmake_test instead of run_test for the regression tests.
For example, you can find some tutorials here, like Tutorial WW3 compilation which include running a regression test.

@jaslanli Hey!

It's been a long time since I asked this question :)

In this particular case the Intel compiler did not work in my environment. I tried Gnu compiler and it solved the problem.

But now I use the new version of the WW and compile it with cmake
