The ROS example for Simulink
>> robotExROSGetStartedExample
runs fine, but compiling it for real-time execution fails, because the 'slros_initialize.h' is missing. The file should be automatically generated by the files listed in 'MATLAB/R2015a/toolbox/robotics/robotsimulink/robotslros/+robotics/+slros/+internal/+cgen'. The files should generate and save C++ code for creating a ROS node, and for creating C++ subscribers and publishers corresponding to Subscribe and Publish blocks in the model. However, they don't. The file 'slros_initialize.h' is not generated in the build folder or anywhere else on the system.
How can this issue be resolved?

I solved this problem by setting: code--> c/c++-Code --> Code Generation Options --> Hardware Implementation --> Hardware board
set this parameter to ROS.

Hello Markus,
As Tobias suggested, please change the hardware board seeting to 'Robot Operating System (ROS)'. This is required to ensure the code generation process pick up all required predefined codes.
Thanks,
Josh
