Could Not Find C:\SimulationInterfaceToolkit\untitled_nidll_rtw\*.obj

[sidaoui@eng.kuniv.edu.kw]

Hello,

I am trying to make use of Simulink Interface Toolkit LabView2009

with Simulink Matlab 2009b 

when i build the simulink file i get error as stated below

" Invalid setting for environment variable MSDevDir or DevEnvDir.
The setting is: ''
You can verify the setting by checking for the existence of:
%DevEnvDir%\..\tools\vsvars32.bat (for Visual C/C++ 9.0)
%MSDevDir%\..\..\vc98\bin\vcvars32.bat (for Visual C/C++ 6.0)
%DevEnvDir%\..\tools\vsvars32.bat (for Visual C/C++ 8.0)
%DevEnvDir%\..\tools\vsvars32.bat (for Visual C/C++ 7.1)
%DevEnvDir%\..\tools\vsvars32.bat (for Visual C/C++ 8.0)

You must define MSDevDir or DevEnvDir to be:
set %DevEnvDir%=<VisualRoot>\common7\ide (for Visual C/C++ 9.0)
set %MSDevDir%=<VisualRoot>\common\msdev98 (for Visual C/C++ 6.0)
set %DevEnvDir%=<VisualRoot>\common7\ide (for Visual C/C++ 8.0)
set %DevEnvDir%=<VisualRoot>\common7\ide (for Visual C/C++ 7.1)
set %DevEnvDir%=<VisualRoot>\common7\ide (for Visual C/C++ 8.0)

This error may be due to an invalid preference file:
C:\Documents and Settings\Nada\Application Data\MathWorks\MATLAB\R2009b\mexopts.bat
Please run "mex -setup" at the MATLAB prompt to correct"

Any idea to solve this problem ?!

i tried many times  "mex -setup"  but useless !!!

Thanks

Hi,

What compiler are you trying to use.  The SIT readme lists different compilers that are supported: http://digital.ni.com/public.nsf/allkb/9B769CC7BCB0AD7E86257603006CF042

Are you using one of these?

If you are using one of these, could you be a little more specific about when you are getting this error?  Which step in this list is actually generating the error: http://zone.ni.com/reference/en-XX/help/371504E-01/lvsithowto/sit_h_convert_model_to_dll/

I had a similar problme recently, then I figured out that my settings of the code generator were different from defaults values. With the default settings for nidll.tlc I could compile code into dll successfully.

Also,.....some versions of C++ compilers are not working for this simulink model code generation, better to check Mathworks site for more info.
