MATLAB: Do I get an error when I try to generate code for the tornado target when the model contains a referenced model in Real-Time Workshop 7.0 (R2007b)

simulink coder

My model contains a model reference block and when I try to build for the tornado target I get the error message:

 Error using ==> genMakefileAndBuild at 875
 ### Model Reference requires the makefile to support compilation. Consider updating makefile:'Mathworks_2007b/rtw/c/tornado/tornado.tmf' or selecting 'Generate code only'

The TLC file that we ship with MATLAB for the tornado target does not, by default, support model referencing. We do, however, provide an example template makefile for the tornado target that will allow you to use model referencing with the RTW Embedded Coder.

To get build successfully change the the system target file to 'ert.tlc' in the Configuration Parameters dialog window, then change the template makefile to 'ert_tornado.tmf' in the same window.

Note that you will need to do this for all models in the hierarchy.

There is a documentation section titled "Supporting Model Referencing" in the Real-Time Workshop Embedded coder docs that explains, in detail, how to create a custom target that supports model referencing.

MATLAB: Do I get the errors about duplicate files with the packNgo function in Real-Time Workshop 5.1 (R2008a)

The packNgo function does not work with RTW generated makefiles.

In order to use the packNgo function uncheck the 'Generate Makefile' option from the Real-Time Workshop settings in the Configuration Parameters window.

For more information on the limitations of the packNgo function see the documentation section titled 'packNGo Function Limitations'.

You can open the documentation directly by executing the following in a MATLAB 2008a command window:

MATLAB: Do I get an identifier “RTWSfcnInfo” is undefined error when building a model that contains S-functions for a custom target in Real-Time Worshop 6.3 (R14SP3)

The RTWSfcnInfo struct is defined in sfcn_bridge.h, which needs to be included when the model is built, by the target template makefile (TMF). The TMF has to define USE_RTMODEL. Our GRT target does it with the following lines of its TMF:

 #------------------------ rtModel ----------------------------------------------
 RTM_CC_OPTS = -DUSE_RTMODEL

This definition starts a whole cascade of dependencies that allows you to use non-inlined S-functions. The RTM_CC_OPTS token is then inserted under the "C Flags" section.
