labwindows OpenGL link error ----- Undefined symbol '_OGLNewCtrl@16' referenced in "ckcviogl.obj".

[whrack]

Hello

I use LabWindows/CVI 2009(Version 9.1.1 ) and want to draw a 3D picture with OpenGL，and I download the OpenGL demo "Rendering a Graph Using OpenGL"（simple_2）from this forum. Then the demo works good in my CVI. 

But when I start to build my project, errors happened showing that 

19 Project link errors

Undefined symbol '_OGLNewCtrl@16' referenced in "ckcviogl.obj".

Undefined symbol '_OGLConvertCtrl@8' referenced in "ckcviogl.obj".

......and so on.

I have add the head file "cviogl.h" and  "cviogl.fp". 

Please help me!

Thanks very much!

Hello whrack,

It sounds to me as though you have not loaded the Instrument Driver for cviogl, which was included in simple_2.zip.  Please try loading cviogl.fp by selecting Instrument»Load from within LabWindows/CVI. After the Instrument Driver has been loaded, it should appear in the Library Tree in the lower left corner. Rebuild your project, and let me know whether you are still experiencing errors.

Warm Regards,
