Simulink model compile error gmake - The make command returned an error of 2

Solved!

Hi everyone,

 

I am attempting to compile a Simulink model into .dll that I can then run on LabVIEW. I have MATLAB R2020a installed (Windows 10) with VeriStand Model Generation Framework and VeriStand Model Framework 2020 R6 also installed. As the compiler, I have MS VS 2019 Pro version installed with all the optional files. 

 

I tested to make sure the compiler is being recognised by MATLAB using the following command in MATLAB:

 

 

mex -setup -v

 

 

I then proceeded to open the MATLAB example "ex_codegen_dsp" to ensure that I can compile regular C/C++ code using Simulink Coder - this also works.

 

I then attempted to generate the LabVIEW .dll file from "ex_codegen_dsp" by setting the stop time to "inf" and changing the system target file to "veristand.tlc" as per the NI documentation. 

 

When I press "Build" the process runs for about a minute before showing the error pasted below.

 

Anyone know what is going wrong or how to fix this?

 

Thanks

UPDATE: I've managed to solve this if anyone else runs into this problem in the future. I followed the solution outlined here: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000001DmQcCAK&l=en-US 

 

Seems like I have to use 'veristand.tlc' as the target file after carrying out the fix in the link above. Using 'NIVeriStand.tlc' still does not generate the .dll file even after applying the fix.
