Dear Foamers,

for the first time, I am trying to compile an application in OpenFOAM.

Regarding my needs, I would like to build the code mentioned in this thread: https://www.cfd-online.com/Forums/op...ary-patch.html

#include "setRootCase.H"
#include "createTime.H"
#include "createMesh.H"

label PatchID = mesh.boundaryMesh().findPatchID("tuyau");

const polyPatch& patchFound = mesh.boundaryMesh()[PatchID];

labelList labelPatchFound( patchFound.meshPoints() );

pointField meshPoints(mesh.points());

long nombre = 0;

forAll(labelPatchFound , label)
{
vector coord = meshPoints[labelPatchFound[label]];
Info << coord[0] << " " << coord[1] << " " << coord[2] << endl;
nombre++;
}

Info << nombre << endl;

Having no idea how to do this I started with the tutorial by Stefan Radl: https://wiki.openfoam.com/Programming_by_Stefan_Radl and also read the guide: https://cfd.direct/openfoam/user-guide/v6-applications/.

After trying to merge a simple code from the tutorial with the above-mentioned code I am getting the following output (errors).

Sadly, I quite not know where to start. Is it a problem of the linking or maybe the code?
/Make/files:

patchPointsOrder.C

EXE = $(FOAM_USER_APPBIN)/patchPointsOrder

/Make/options:

EXE_INC = \
	-I$(LIB_SRC)/finiteVolume/lnInclude \
	-I$(LIB_SRC)/meshTools/lnInclude \
        -I$(LIB_SRC)/OpenFOAM/include
	
EXE_LIBS = \
	-lfiniteVolume

Also, I am not sure what work needs exactly to be done to file the options file in the correct way. So in other works - where or how do I get the information on which paths and libraries I need to put in there?

I would be very happy about any help.

My OpenFOAM is version 3.0.1.

Greetings!
