Thanks for reporting this!

Indeed the file should be put under "codeGenFolder/slprj/target/_sharedutils" when "Shared code placement" is set to "Shared location" as we documented in https://www.mathworks.com/help/rtw/ref/sharedcodeplacement.html

We will look into it.

Meanwhile, the missing header "rtsplntypes.h" can be found under the following folder

MATLABROOT/rtw/c/src

So as a workaround, you can copy "rtsplntypes.h" to your local project folder to compile the generated code without MATLAB.

Hope this help~
