Dear foamers,

I am trying to write a new dynamic motion solver on the basis of "velocityLaplacian". I copied the source codes of "velocityLaplacian" and wrote to a new library "libMyfvMotionSolvers.so".

The code compiles but when I run the simulation (using interDyMFoam), the following error message comes up (dlopen error):

Selecting motion solver: velocityLaplacian
--> FOAM Warning : 
    From function dlOpen(const fileName&, const bool)
    in file POSIX.C at line 1179
    dlopen error : /home/xiaohui/OpenFOAM/xiaohui-2.3.1/platforms/linux64GccDPOpt/lib/libMyfvMotionSolvers.so: undefined symbol: _ZN4Foam18fvMotionSolverCore5debugE

--> FOAM FATAL ERROR:

    From function motionSolver::New(const polyMesh& mesh)
    in file motionSolver/motionSolver/motionSolver.C at line 116.

FOAM exiting

I tried the following methods but none of them works:
1) change the names;
2) add links to dynamicMesh and dynamicFvMesh etc.;
3) re-install swak4Foam;
etc.


Can anybody drop a hint? Thanks in advance.

Clark
