Compilation problem of "simpleFsi-OF4.1" in foam-extend 4.1

[subhasisarath]

I am facing some compilation problems while compiling the "simpleFsi-OF4.1" in foam-extend 4.1 using Ubuntu 18.04.
Error Message:
basicFsi.H:45:10: fatal error: forces.H: No such file or directory
#include "forces.H"
compilation terminated.

May I know the exact procedure to compile "make libso"?
Exactly where should I put the folder "basicFsiFunctionObject" before compilation?

Thanks for your reply @unicfdlab
Now I tried to compile it in official OpenFOAM v7 and successfully compiled the "basicFsi" and "helloWorld" function objects. However, I a, facing an error while complying with the "weaklyCoupledFsi" function object.
Error Message:
weaklyCoupledFsi.C:198:43: error: ‘class Foam::IOobject’ has no member named ‘headerOk’
if (weaklyCoupledFsiFsiHeader.headerOk())

How can I solve this issue?

Hi!
Folders in the repository are organizes according to the next rule: <Case>-<OF version> ,
where <Case> is the name of problem and <OF-version> can be one of:

• OF3.0.0 - OpenFOAM ver. 3.0.0
• OF4.1 - OpenFOAM ver. 4.1
• OFv1812 - OpenFOAM+ v. 1812
• OFv1912 - OpenFOAM+ v. 1912
• OFv2012 - OpenFOAM+ v. 2012

You have to use exactly the same version of OpenFOAM for each folder
