Adapter is not yet ported to preCICE v3

[tapegoji]

I followed the isntructions of how to compile it. However, I faced an issue with it. Have you seen this error?

`../Coupler_Solver.so: undefined symbol: precicef_is_action_required_

It seems that this is not being updated for v3. How can I help in this? need guidance.

Yes, the adapter has not yet been ported to v3. Any help in this direction is highly appreciated.

There is a porting guide, focusing on the C++ API. You can follow this guide for Fortran pretty much as well. For the exact names of the functions, have a look at the source code.

I would recommend opening a draft PR early and ask for help there if you run into issues.

Hey, I was able to successfully port it. However, I needed to do a lot of changes. Let me know what you think.
