gmake: *** [sldrt_main.obj] Error 1
Error(s) encountered while building "HIL_squirrel_cage_test_at_1ms_sampling_time"

The error popped up while trying to build a code for a desktop real time target. I have checked "Allow non finite numbers" in the configuration options and yet the error persists. Unable to find the file in the MATLAB root. Please suggest a fix.

[Birdman]

Have you checked it? You should uncheck it to get rid of that header and its build.

[Balakrishnan Rajan]

Yes I unchecked it, but it still throws up the same error. Is there any other option that invokes this header?

[Birdman]

Can you send me your model(export to r2017a)?

[Balakrishnan Rajan]

It needs the .m script to be run to initialise the parameters.

[Birdman]

Your m file gives an error because of second_order_filter function. Did you forget to send it?

[Balakrishnan Rajan]

I am attaching it now. Actually, it is not needed for the current model. It is required for a larger model that will implement a filter at one of the outputs of the current model. The line where it occurs can be commented out. Pardon my oversight.

Also how do you link the m script to the model? I didnt get to that stage at all as it threw the rt_nonfinite error.

Sorry about the inconvenience. Thank you very much for the help.

[Birdman]

The attached file contains your model and necessary header file. Put them in your directory and generate C code without any error. It worked in my computer.

[Balakrishnan Rajan]

How did it work? Was the issue because my "rt_nonfinite.h" is missing in my MATLAB installation?

Thank you very much for the solution !!

[Birdman]

No, it was also missing in my folder too, I had to take it from internet.

[Balakrishnan Rajan]

Oh, Thanks
