DLL Generation Failure

[EEMontalvo]

Essentially I was not being able to generate a .dll file
using Mathwors Real Time Workshop.

I  was able to run the build process in Mathworks and get to the
message:
### Successful completion of Real-Time Workshop build procedure for model:
NEWSineWaveSIT.

However, even though I do this, I have two issues:

1) I cannot find any .dll file in the directory

2) I have a question about the configuration of the build process. Should Icheck or uncheck the "Generate Makefile" Option on the Real Time Workshop tab of the Configuration Parameters? Mathworks said they guess I should have it unchecked, but to ask someone from NI to be sure.

When I check the box it gives me back an error which just says:

Error(s) encountered while building model "NEWSineWaveSIT"

When I unchecked the box, I got this:

## SIT 2009 Modifying NEWSineWaveSIT.c file
Warning:  Unknown data type.  Constructor is "void"
Warning:  Unknown data type.  Constructor is "enum"
Warning:  Unknown data type.  Constructor is "enum"
.

rtw\*.obj
### Creating project marker file: rtw_proj.tmw
### Successful completion of Real-Time Workshop build procedure for model:
NEWSineWaveSIT

Does anyone have any idea of what could be causing this? I have attached Pictures of the model I want to convert to dll and how I have configured the Real Time Workshop window.
