I'm trying to port some code from the OpenFOAM-Dev github repository to work with my ESI installation.

Upon running wmake it's thrown two errors - one was easily fixed by substituting "vSmall" for "VSMALL", which I did by comparing equivalent files and noticing that the only difference was the capitalisation. Unfortunately the other error seems to be less easily fixed. It's complaining about the following:

MPLIC/MPLICfaceI.H: In member function ‘const vector Foam::MPLICface::Sf() const’:
MPLIC/MPLICfaceI.H:117:18: error: ‘area’ is not a member of ‘Foam::face’
     return face::area(subPoints_);
                  ^~~~

Have had a rummage in the source, it looks to me that what it needs is defined in src/OpenFOAM/meshes/meshShapes/face/face.C. Comparing the two forks versions of this file it looks like ESI have a "areaNormal" in an equivalent place in the file to foundations "area"; I don't understand the full workings, but comparing to other surrounding functions it initially looks equivalent.

Unfortunately my optimistic 'swap them over' didn't work - it produces this error:

MPLIC/MPLICfaceI.H:117:39: error: cannot call member function ‘Foam::vector Foam::face::areaNormal(const Foam::UList<Foam::Vector<double> >&) const’ without object
     return face::areaNormal(subPoints_);
                                       ^

My C++ isn't great, but it seems that these are actually not equivalent functions. Does anyone know if this is a simple case of substituting one thing for another, or do the incompatibilities between forks actually run much deeper here?

Thanks,
Mike
