build errors for simulink models with muliti processor topology for target DS1007

I was able to build models earlier but I start seeing this errors after I upgraded my RTI software. I know its too vague but can anyone give any hints on where to look at to start debugging to find the root cause? Thanks in advance.

Hello Kausalya Singuru,

I am running into a similar error. Where you able to find any information about this issue?

In my case it was because of some pre existing generated code in the build path. I cleaned all the pre existing code and regenrated all the files and the model built with no errors. My suggestion is to do a clean build.
