Found an error during compilation of the library on a cluster, in file:
fluidSolvers/finiteVolume/RBFMeshMotionSolver/RBFMeshMotionSolver.C
in line 297:5: error: ‘vector’ is not a member of ‘std’. Managed it by including the vector library in the file. May affect other users as well. Log file attached.

If you're using foam-extend 4.0, then you must use the package that was developed for that version, namely this one: http://openfoamwiki.net/index.php/Extend-bazaar/Toolkits/Fluid-structure_interaction#Install_on_foam-extend-4.0

Im using Fsi_40.tar.gz on foam-extend-4.0 and still get the same error. I also tried to compile other versions but it didnt work:

luidSolvers/finiteVolume/RBFMeshMotionSolver/RBFMeshMotionSolver.C: In member function ‘virtual void Foam::RBFMeshMotionSolver::solve()’:

@arionf: Which GCC version are you using? Namely what do the following commands give you?

gcc --version
g++ --version

I'm currently re-building foam-extend 4.0 on a VM with Ubuntu 18.04. However, I've using GCC 5, as instructed here: https://openfoamwiki.net/index.php/Installation/Linux/foam-extend-4.0/Ubuntu#Ubuntu_18.04

What I mean by this is that it is my suspicion and vague memory that GCC 7 does not use the same STL structure that GCC 5 uses. In other words, std::vector has changed how its meant to be used.

I don't know how much foam-extend 4.0 has been tested with GCC 7, so I don't know if it's stable enough and/or if everything builds as intended. However, it should work fairly well with GCC 5.

That said, the solids4foam project is still in development and I don't know when they will release it, but it should better support the more recent GCC versions, as well as the more recent foam-extend 4.1 that is in development.

I'll report back here once I'm managed to finish testing building myself the FSI toolkit for foam-extend 4.0, but I've dropped by just in case I forget to write about this until then.

OK, the good/bad news is that this issue occurs also with GCC 5...

I guess I will really have to bring in the code from openfoamwiki and re-adapt it...

I've finally managed to look into this and the solution is apparently fairly simple... all that was missing is the addition of this line:

#include <vector>

next to the other includes in the file src/fluidSolidInteraction/fluidSolvers/finiteVolume/RBFMeshMotionSolver/RBFMeshMotionSolver.C.

A quick way to apply this fix is to run the following command before running Allwmake:

sed -i -e 's=\(using namespace\)=#include <vector>\n\1=' fluidSolidInteraction/fluidSolvers/finiteVolume/RBFMeshMotionSolver/RBFMeshMotionSolver.C

Warning: I tested this only on Ubuntu 18.04, using GCC 5.5.0.
