link errors

[RogerMon]

Hi!

I'm the NPS (Next Poor Sucker)  I'm assigned to learn CVI and maintain a rather complex application.  For openers, I'm trying to install it on a new machine.  When I first tried to compile and run in debug mode, there were issues with missing include files.  I found and supplied them.

Now I'm getting the link errors listed below.   I guess that there is still something missing, but I don't know what

Any help is appreciated.

It looks like you're missing the tools librarys that NI ships with CVI.  There are a couple of ways to add these to your environment.  The easiest, and the way your predecessor probably did is to select Library | Customize...  Then click on Browse...   and browse to c:\program files\National Instruments\CVI71\toolslib\toolbox and select asynctmr.fp.   This will take care of the asynctmr methods that aren't linking.  The toolbar methods are handled by c:\program files\National Instruments\CVI71\toolslib\custctrl and select toolbar.fp.  Once you restart CVI you should be able to build.  If you choose this method I would recommend removing the .h files you added to your project.

Hello Roger,

You have to load the instruments, containing these functions. To do so, pull down the Instrument menu and select Load.

You can find the instruments needed here:

-   C:\Program Files\National Instruments\CVI80\toolslib\toolbox\asynctmr.fp

-   C:\Program Files\National Instruments\CVI80\toolslib\custctrl\toolbar.fp

And you will need to add c:\program files\national instruments\cvi71\toolslib\custctrl\movectrl.fp

The "cvixx" folder in all these paths must match the cvi version number of your cvi: it may be cvi70, cvi71 or cvi80 depending on which version of cvi you are using (from 7.0 on).

If you are running CVI6.x this directory defaults to C:\program files\National Instruments\MeasurementStudio\CVI\....
