MATLAB: Do I receive an error regarding incompatible types when building the model in Real-Time Workshop 5.1 (R13SP1)

When I build my model files, I receive the following error during the compile stage of the build process:

 ### Compiling NewMotorFish.c

This bug has been fixed for Release 14 SP1 (R14SP1). For previous releases, please read below for any possible workarounds:

This has been verified as a bug in Real-Time Workshop 5.1 (R13SP1) in the way that code is generated from atomic subsystems. Currently, to work around this issue, try the following:

1) Right-click on the subsystem(s) whose generated code is producing an error and select "Subsystem parameters ..."

2) Check "Treat as atomic unit"

3) Change the "RTW system code" property from Auto to Function.

4) After the changes have been made, rebuild the model.

MATLAB: Do I receive errors when building the model containing custom code in a reusable function when using Real-Time Workshop 6.6 (R2007a)

This bug has been fixed in Release 2007b (R2007b). For previous product releases, read below for any possible workarounds:

The error is received because the following statement is added to the field "Configuration Parameters -> Real-Time Workshop -> Custom code -> Include custom c-code in generated -> Source file"

 #include "my_header.h"

As a workaround add the statement to the "Header file" field. The model header file is included in every subsystem source file, so there should not be any undeclared identifiers.

MATLAB: Am I unable to generate code for a Simulink model with a while subsystem using Real-Time Workshop

This bug has been fixed for Release 14 SP1 (R14SP1). For previous releases, please read below for any possible workarounds:

This has been verified as a bug in Real-Time Workshop in the way that it handles

code generation for a model with a 'while subsystem'.

You are likely to encounter this issue if the model satisfies the following conditions:

1. Iterator subsystem containing another atomic subsystem

2. An input to the atomic subsystem is also a canonical input to the iterator subsystem

3. The Atomic subsystem does not require output and update to be combined

4. At least one of the sources of the Atomic subsystem executes after the atomic subsystem

5. Atomic subsystem does not have direct feed through

Currently, to work around this issue, try adding a Gain block between the atomic subsystem and the input port of the iterator subsystem so it will no longer be a canonical input to the iterator system.
