Compiling And Linking; The Complete Application Program In C - National Instruments GPIB-PCII Getting Started

Writing an Advanced Program Using NI-488.2 Routines

Compiling and Linking

To create an executable program, complete the following steps:
1. Copy the QuickBASIC 4.5 language interface (QBIB.OBJ) from the
C:\GPIB-PC directory, which was set up during installation, into your
QuickBASIC directory (C:\QB45 in this example).
2. Compile the application program (assume the example program you just
created is in a file called ACVOLTS.BAS).
bc /o acvolts.bas;
3. Link in the language interface by entering the following command:
link acvolts.obj+qbib.obj;
link creates an executable file named ACVOLTS.EXE.
4. If you have a Fluke 45 DVM, run the program by entering the following
command:
acvolts
