NI-DAQmx 6008 Mac OSX

[Daniel Jean]

I tried to use the example acquire1Scan.c to acquire a simple voltage on my 6008. It returns the following message: ZeroLink: unknown symbol '_DAQmxBaseCreateTask'
The NIDAQmxBase.h is located in the "Other Sources" folder.
I should forget something...
Thank you for your help.

int main(int argc, char *argv[])

Error:

Hello.

To begin, you have an alone  " #include " command 😉

Corresponding to the error message, the application doesn't  find your header. You need to specify the folder in development environnement or to attach the header to your project.

Hope this helps.
