Hello everyone,
I am trying to add a new boundary condition for epsilon using wmake libso.
I have successfully compiled the boundary condition and added the library in controlDict. However while running simpleFoam, I am getting the following error

--> FOAM Warning :
    From function void* Foam::dlOpen(const Foam::fileName&, bool)
    in file POSIX.C at line 1251
    dlopen error : /home/subhojik/OpenFOAM/subhojik-8/platforms/linux64GccDPInt32Opt/lib/libmyEpsilonFreeSurface.so: undefined symbol: _ZTVN4Foam38myEpsilonFreeSurfaceFvPatchScalarFieldE
--> FOAM Warning :
    From function bool Foam::dlLibraryTable::open(const Foam::fileName&, bool)
    in file db/dynamicLibrary/dlLibraryTable/dlLibraryTable.C at line 106
    could not load "libmyEpsilonFreeSurface.so"

.....
--> FOAM FATAL IO ERROR:
Unknown patchField type myEpsilonFreeSurface for patch type patch

Valid patchField types are :
......

The Make/files and options are

fvPatchFields = fields/fvPatchFields
derivedFvPatchFields = $(fvPatchFields)/derived
$(derivedFvPatchFields)/myEpsilonFreeSurface/myEpsilonFreeSurfaceFvPatchScalarField.C

LIB = $(FOAM_USER_LIBBIN)/libmyEpsilonFreeSurface

and

EXE_INC = \
    -I$(LIB_SRC)/meshTools/lnInclude \
    -I$(LIB_SRC)/finiteVolume/lnInclude \

LIB_LIBS = \
    -lmeshTools \
    -lfiniteVolume

Could you please suggest the necessary correction? I am using OF 8 in Win 10.
Thanking you.

Hi Subhojit,

Nothing seems wrong in the provided code snippet. These errors usually mean that you have to wclean and wmake again.

Hi!


Could you fixed it?


I am using OF8 as well and facing exactly the same problem
