Not able to create OUT file with "nidll_vxworks" in Matlab for use with the LabVIEW SIT 2010 and a cRio 9073, sh.exe error

[jarcTek]

I am trying to compile an OUT file for my Simulink model using "nidll_vxworks" and run it using the Simulation Interface Toolkit for a cRIO 9073 . I am able to compile the DLL file using "nidll" and succesfully run the simulation using my PC as the host.

I already downloaded the "gccdist" and "vxworks61gccdist" folders and copied them to "c:" When I build the model in Sumulink I get the following error at the end of the process (at the same time windows tells me that "sh.exe" has stopped working). If it matters I am running Windows 7 64bits, but using Matlab 2009b 32bits and LabView 2010 32 bits. ANY HELP WILL BE APPRECIATED. "QofV" is the name of my Simulink model and I changed to "XXX" parts of the file path.

In addition. I manage to create the QofV.OUT file sometimes. It looks very random to me. With the same Simulink model I get the error most of the time, but once every 100 compilations it works. I am thinking there is another process that makes the sh.exe crash.

GCC 6.1 is only suported on Windows XP.  It is almost noted in the readme_sit_vxworks.txt that can be found in C:\SimulationInterfaceToolkit\xxxx\VxWorks (where xxxx is the version of SIT).  It says:

*Known Issues
---------------------------
- The WindRiver GNU Toolchain 6.3 and 6.1 do not work on Windows Vista.

To be more explicit it should be "Vista and later".

Ok. Thanks.

Do I have an option if I want to use my Win 7 machine?

Thank you again for your reply!

Hello jarcTec,

I am not sure right now if you can do it, but this tutorial might help, also everything was made in Winddows 7 in this one.

Take a quick look and let me know if it works!!!

Hello Luis.

I was actually using that tutorial when I ran into the problem described above. It may not be an issue with Windows 7 but with Windows 64 bits in general. 

I managed to get an XP 32bits machine and compile the out files there without a problem.

Regards,
