How to suppress unwanted lines from ert generated code

The header file of my generated code contains unused include statements as #include stdlib.h #include math.h #include stddef.h

Also it has following comments at the end of file

/* 
* The generated code includes comments that allow you to trace directly 
* back to the appropriate location in the model. The basic format 
* is <system>/block_name, where system is the system number (uniquely 
* assigned by Simulink) and block_name is the name of the block. 
* 
* Use the MATLAB hilite_system command to trace the generated code back 
* to the model. For example, 
* 
* hilite_system('<S3>') - opens system 3 
* hilite_system('<S3>/Kp') - opens and selects block Kp which resides in S3 
* 
* Here is the system hierarchy for this model 
* 
* '<Root>' : cmp 
* '<S1>' : cmp/Subsystem 
* '<S2>' : cmp/Subsystem/Chart 
*/
Can anybody have idea how to suppress unwanted lines from generated code.

Thanks.

Which version of MATLAB are you using? Most of the problems with unnecessary header includes added to the generated code should be fixed in newer versions. If it is still a problem you can always add a PostCodeGenCommand to manually remove unnecessary header includes.

About the comment: you have the option to remove all comments with the Comments pane in Configuration Parameters. This comment itself is explaining the code-to-model traceability which is available for Embedded Coder generated code. Are you using Embedded Coder or Simulink Coder?

I am using embedded coder with Matlab R2007a. If i disable the overall control to include comment, it will not generate user comments and stateflow states & transition comment also. I want to keep them.

I think code ouput buffer can be processed before printing to the output file using a 'custom file processing templete'. But due to lack of documentation i am not able to use it.

Finally i have decidede to write m-script to post-process the generated files and remove unwanted contents.

Perhaps the above quoted comments can be eliminated by unchecking code-to-model highlighting? This option should be in Real-Time Workshop>Report pane.

I think 'code-to-model' option generates hyperlinks in the generated report. These links refer the block in the model.

It does not suppress the comment in the code.

If it is possible for you to upgrade your MATLAB version to R2009b or higher you probably will not have any problems with the unnecessary includes. The only workaround in older versions as R2007a would be to use a PostCodeGenCommand.

The comment will not be removed when you uncheck the code-to-model highlighting. If you would like to get rid of the comment once and for all but do not want to disable all comments you could simply remove this from the corresponding TLC file:

$MATLABROOT$\rtw\c\tlc\mw\commonhdrlib.tlc (lines 749-804)
