Linking to VISA Libraries
Your application must link to one of the VISA import libraries:
32-bit Version:
C:\VXIPNP\WIN95\LIB\MSC\VISA32.LIB for Microsoft compilers
C:\VXIPNP\WIN95\LIB\BC\VISA32.LIB for Borland compilers
16-bit Version:
C:\VXIPNP\WIN\LIB\MSC\VISA.LIB for Microsoft compilers
C:\VXIPNP\WIN\LIB\BC\VISA.LIB for Borland compilers
See the following section, “Compiling and Linking a VISA Program” for
information on how to use the VISA run-time libraries.
Compiling and Linking a VISA Program
32-bit Applications
The following is a summary of important compiler-specific
considerations for several C/C++ compiler products when developing
WIN32 applications.
For Microsoft Visual C++ version 2.0 compilers:
• Select Project | Update All Dependencies from the menu.
• Select Project | Settings from the menu. Click on the C/C++
button. Select Code Generation from the Use Run-Time
Libraries list box. VISA requires these definitions for WIN32.
Click on OK to close the dialog boxes.
• Select Project | Settings from the menu. Click on the Link
button and add visa32.lib to the Object / Library Modules
list box. Optionally, you may add the library directly to your project
file. Click on OK to close the dialog boxes.
• You may wish to add the include file and library file search paths.
They are set by doing the following:
1. Select Tools | Options from the menu.
2. Click on the Directories button to set the include file path.
3. Select Include Files from the Show Directories For list
box.
4. Click on the Add button and type in the following:
C:\VXIPNP\WIN95\INCLUDE
5. Select Library Files from the Show Directories For list
box.
