I'm getting this "error LNK2001: unresolved external symbol _niFgen_SendSoftwareTrigger@4" when I try to make any CNiFgen object.

Hi, I have a working project that has a few classes using the NI5411 APIs and now I want to use CNiFgen classes. After adding Core Components(Advanced Analysis, Common) and NI Device Instrument Drivers(NiFgen) from the Measurement Studio Components Wizard. Even when I try to make an object of CNiFgen(CNiFgen cnf I get the following error:
--------------------Configuration: puzzle - Win32 Debug--------------------
Linking...
NiFgenInterfaceD.lib(NiFgenImpl.obj) : error LNK2001: unresolved external symbol _niFgen_SendSoftwareTrigger@4
Output/puzzle.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
puzzle.exe
- 2 error(s), 0 warning(s)
My APIs version is working fine and so are these CNiFgen classes(I have tried then for a dummy project). But, things start getting nasty when I try to integrate them.
Regards,
Vaibhav.

It looks like you have a typical linking error in VC++. Have you made sure that all of the necessary .lib files are properly linked to?
Also, are you passing any data between your custom classes and the niFGEN classes? These will take different data types unless you have already type cast all of them to work properly together. If they don't share variables, you should be okay.

    Millions of thanks for any kind of feedback ;-)

    Have you succeeded? I tried vs2012 and it passed compilation, but gave the run-time error of _crtisvalidheappointer. But the same code runs well with vs2010.

  • C++ Kinect SDK: error LNK2019 unresolved external symbol

    I'm receiving the message "error: LNK2019" error when I attempt to run a basic C++ Kinect program.  I am running Windows 7 32bit with the Kinect SDK 1.0 and developing in Visual Studio 2010.  The included Skeletal Viewer sample works correctly,
    so I believe my problem lies in the project configuration.  I tried comparing my project config to the sample's, but I can't find any differences so I thought I'd open this up to the forums.  Is there any missing or incorrect information that I'm
    not seeing?  Or is there some other configuration I should be checking?
    Thank you in advance.

    Is kinect10.lib listed among the libraries in your project's properties, under Linker | Input | Additional Dependencies?
    If not, that is the likely cause for the errors.

    That was it!  Thank you for the quick response and the clear directions.
    Since I see you're with Microsoft, I'd like to point out this step was missing from the set up instructions that come with the SDK installation.  This guide says to link kinect10.lib by linking
    $(KINECTSDK10_DIR)\lib\x86;  As we saw here, that's not quite the same thing!

    Hi, 
    The link to the following include path has been added by two ways in Microsoft Visual Studio 2008.
    C:\Program Files (x86)\National Instruments\CVI2013\toolslib\toolbox
    (1) [menu bar, Tools -> Options -> Projects and Solutions -> VC++ Directories -> Include files
    (2) [menu bar, Project -> Configuration Properties -> C/C++ -> General -> Additional Include Directories
    "cvisupp.lib" and "cviwmain.lib" are added to linker input. I cannot find this one in my NI folders "cvirte.dll".
    In my MSVS project, add "cvixml.c" to the Source Files folder and "cvixml.obj" to the Resource Files folder.
    With the above settings, it ends up with the following compilation error.
    If we roll back to the initial code in the beginning of this discussion thread, we probably just miss one lib file or a few which contains CVIWindows XML function tree.

  • Error LNK2019: unresolved external symbol

    Hi there,
    I'm trying to instantiate a Factory object to then get a SchemaValidator from createSchemaValidator.

    Basically, I can't seem to find the right template argument which is supposed to be of type "Context" but I can't figure it out. I tried using "xmlctx" but that leads to the following compiling error:

    Since you got this issue when compiling my code which seems that this issue is related to your project, and this forum is to discuss and ask questions about the
