Undefined symbol "_CW3DGraphLib_CWPlots3DItem@28'

Hi,

I have cutted and pasted some part of the example " 3DGraph" of Labwindows 9.0 for my project but there are some error such as : 

3 Project link errors
Undefined symbol '_CW3DGraphLib_CWPlots3DItem@28' referenced in "Sensore_HC_SR04.c".
Undefined symbol '_CW3DGraphLib_CWPlot3DPlot3DSimpleSurface@40' referenced in "Sensore_HC_SR04.c".
Undefined symbol '_CW3DGraphLib__DCWGraph3DGetPlots@12' referenced in "Sensore_HC_SR04.c".

and I don't understand why...

May you help me? 

Thank you

Did you also add the instrument driver toolslib\custctrl\3DGraphCtrl.fp to your project? It contains the functions for creating and configuring the 3D graph. And you also should add the line

#include "3DGraphCtrl.h"

to your source code. This header file provides the declarations of the functions and related variables.

Thank you for reply Wolfgang

Now I have insert the 3DGraph.fp and also the 3DGraph library but when I start the simulation it crashes and It don't send nobody message of error.

I use Windows8, perhaps this is the problem?

The 3DGraphCtrl.fp instrument driver is not supported for 64-bit applications, so if you are running a 64 bit Windows this might explain your crash.

No, I'm working in 32bit but I resolved the problem thank you so much.
