ExportModuleLsm.cpp.obj : error LNK2019 for esys-particle-win building

Asked by guo

Hello all,
I am using the esys-particle-win 2.1, but the TriangleFieldSaverPrmsPy is unavailable. So i want to add this into esys-particle-win.
What I did is that: (according Dion's suggestion https://answers.launchpad.net/esys-particle/+question/193362)

step 1. I used the files in the following( http://bazaar.launchpad.net/~esys-p-dev/esys-particle/trunk/revision/1003) change the files in my bazaar path (C:\Program Files (x86)\Bazaar\esys-particle-win\trunk )
Geometry/Triangle.h
Model/TriMesh.cpp
Python/esys/lsm/ExportModuleLsm.cpp
Python/esys/lsm/LsmMpiPy.cpp
Python/esys/lsm/LsmMpiPy.h
Python/esys/lsm/Makefile.am
Python/esys/lsm/TriangleFieldSaverPrmsPy.cpp
Python/esys/lsm/TriangleFieldSaverPrmsPy.h
step 2. add TriangleFieldSaverPrmsPy.cpp and TriangleFieldSaverPrmsPy.h in the "set set(LibLsmPy_LIB_SRCS" part in cmakelists.txt in folder "C:\Program Files (x86)\Bazaar\esys-particle-win\trunk\Python\esys\lsm"
step 3. rebuild esys-particle-win as described in "ESyS-Particle-win Build Instructions 2 April 2012"

However, an error happened as follows: after a hard search I still cannot fix it.

Could anyone help me on this, Thanks very much!

Hi, Guo:

You need to add windows DLL export/import specifier "DECLSPEC_LSM_PY" in front of your exportTriangleFieldSaverPrms:

so in your TriangleFieldSaverPrmsPy.h, line 37

instead of the current definition:

void exportTriangleFieldSaverPrms();

you should have

void DECLSPEC_LSM_PY exportTriangleFieldSaverPrms();

See if this works!

Thank you Feng,
I have successfully added the function, but when I run the python script, the following error happens.
it seems that error occurs at "timeStepIncr=100".
I tried to change the value, but still cannot works.

Hi, Guo:

Can you check your python parameters and see if they match the C++ definitions?

Thank you Feng,
I change the code fragment in my python script blew:

prm=TriangleVectorFieldSaverPrms(
 meshName="intruder_wall",
 fieldName="force",
       fileName="out_drag_force.dat",
 fileFormat="RAW",
 beginTimeStep=0,
 endTimeStep=10000,
 timeStepIncr=100
)
sim.addVectorTriangleSaveField(prm)

And it works, i forget add the fileName function in it.
