Using nidll.tlc: could not find *.obj

[Bladhart]

I am using the NI SIT, and with it comes a nidll.tlc which I can use to build Matlab models into .dll files. When I build, Matlab would say that the build was successful, but not .dll can be found anywhere. In the Matlab screen, the only thing that indicates something went wrong is: Could Not Find C:\Program Files\National Instruments\LabVIEW 2010\examples\Simulation Interface\Sine Wave\sinewave_nidll_rtw\*.obj 

Can someone help with a) figuring out why no .dll file was generated, or b) why this *obj file could not be found? Thanks.

Please choose your compiler for building external interface (MEX) files: 

Would you like mex to locate installed compilers [y]/n? y

Select a compiler: 

[1] Lcc-win32 C 2.4.1 in C:\PROGRA~1\MATLAB\R2008a\sys\lcc\bin 

[2] Microsoft Visual C++ 2008 in C:\Program Files\Microsoft Visual Studio 9.0 

[3] Microsoft Visual C++ .NET 2003 in C:\Program Files\Microsoft Visual Studio .NET 2003 

[0] None 

Compiler: 3

Please verify your choices: 

Compiler: Microsoft Visual C++ .NET 2003  

Location: C:\Program Files\Microsoft Visual Studio .NET 2003 

Are these correct [y]/n? y

Warning: MEX requires that the Microsoft Visual C++ 7.1 

directories "Vc7" and "Common7" be located within the same parent directory. 

(Expected to find these directories in 'C:\Program Files\Microsoft Visual Studio .NET 2003'.)

Hi,

This appears to be a pretty complex issue.  I'm not sure why no .dll file was generated off the top of my head, but I'll continue to work on this and try to figure out why it's not.

Hi Guys, 

        I am also having the same problem. Did anyone solve this issue.

Regards,

Kumar

Hi Kumar,

Are you using a supported compiler?  If you are using Visual Studio Express, there are a few more steps you need to follow to set everything up correctly, which you can find here:

Can I Use a Free Compiler with SIT?

Hi, 

  Thank you for your comment. I am using Visual studion 2008. 

I want to indicate something here. Eventhough, I get the same error, I am able to generate the .dll file and the .dll file works very well. I wanted to make sure that this error does not create any further error when using the .dll file. 

Regards,

Kumar
