Problems with cvistart.lib from CVI 5.5

[DimasRex]

I downloaded some instrument drivers from the NI website. To control a Kepco Power Supply an a Keithley Voltmeter. When Debugging both drivers return:
1 Project link error
Undefine symbol '_main' referenced in
"c:\measurementstudio\cvi\bin\cvistart.lib"

You might want to check that you are set to the same compiler as the project you downloaded (MS / Watcom etc etc)...

This means you didn't write a main function for your exe. The cvistart.lib is checking your code for a main function and you didn't provide one. You can't just build an instrument driver into a EXE. It is just a library of functions. You have to write an application to USE the instrument driver.

In ANSI C, you must have a main function for your application to know what to run when the EXE starts. See any of the examples in cvi\samples\ to see main function examples.
