Including Agilent Drivers in Ansi-C VS2010 Project results in error LNK2001

I am unable to resolve a linker error

my projects includes in one of its c files:

#include "../bin/AgN6700/agN6700.h"
#pragma comment(lib, "bin/AgN6700/agN6700.lib")

This is a adaption to a powersupply. This adaption has several dependencies.

76 symbols fail to link. 8 are defined in the ivi.h 76 are defined in the visa.h

dependencies-and-errors

I have lib files for both of them on my machine in the folder:

C:\Program Files (x86)\National Instruments\Shared\CVI\ExtLib\msvc

So i added this folder to the library entrie in the VS2010 Project.

VS2010-Folder

What is going wrong here? How can i investigate and solve this issue?

The full list of LNK2001 errors:

agN6700.lib(agn6700.c) : error LNK2001: ... Symbol "...".

Solution

  • It seems i misunderstood how lib files are included in the buildprocess.

    The solution is to supply the linker with additional dependencies via the project properties.

    This is illustrated in this stackoverflow post.
