Error creating DLL with Real time workshop (SIT)

[Nacho_s]

When I try to generate a DLL model from a simulink model using the NIDLL target in Simulink I get the following errors:

### TLC code generation complete.

If I perform the same operation but changing the Simulink target to Generic Real Time (grt.tmf) it works perfectly.

How can it be solved?

Thanks a lot.
