This error code is undefined. Undefined errors might occur for a number of reasons. For example, no one has provided a description for the code, or you might have wired a number that is not an error code to the error code input.

Hi Dany,

It would seem that the error indicates one of your variables may have a character that is not an acceptable C identifier.  Try naming your variables in conduct with these rules.

Hello Cole, in fact the build work in 8.6 it's only on 2011 with Windows XP. I made a simple project that reproduce de problem with LV2011 and windows XP. The same test work correcly on windows 7. 

But for the moment I can't upgrade all my setup to Windows 7.

Hi Dany,

I see that you opened an SR (7351353) with Nathan and that he was able to help you out.  With that, I hope all is well and best of luck with your project!

Yes, we found a workaround to the problem.

The problem was the RFSG reference that cause the building problem. I just changed those cluster with variant and now it build correcly.
