Unable to find 'solver_zc.h' header file in generated code from Embedded Coder

When I add the "external reset" signal to my "PID Controller" block, the resulting model can no longer be compiled in my Embedded Coder target. I get the error message from the compiler: "could not open source file 'solver_zc.h'".

Where do I get this file? Why isn't Embedded Coder adding the file it needs to the "ert_rtw" directory?

Embedded Coder does not place the 'solver_zc.h' file in the build directory. This is the case for several such header files, and is expected behavior. To access the 'solver_zc.h' file, please navigate to the path - 'C:\Program Files\MATLAB\<release>\simulink\include', where "<release>" might instead be "R2016a", as an example.

That being said, to be able to consolidate all the required build files in one folder, it is recommended to use the "packNGo" feature. The "packNGo" function can be used in the following manner, where "myModel.slx" is a Simulink model and "myModel_ert_rtw" is its build folder generated by Embedded Coder:

>> cd myModel_ert_rtw
>> load buildInfo.mat
>> packNGo(buildInfo, packType='hierarchical')

By using "packNGo" in the above manner, a majority of missing dependency issues should be resolved.
