Removal of RT_MODEL variables in code generation

Hello,

I am using R2019b ert.tlc file for code generation.

Question: How to remove code generaiton for the RT_MODEL_m variables which are getting generated ?

Apparently something related is asked earlier in below link, but nobody gave the correct answer.

I suggested the below setting as suggested by the STAFF member, but it didnt help.

cs.set_param('CodeInterfacePackaging', 'Nonreusable function'); % Code interface packaging.

Any help will be appreciated !!!

Look in TEST.h. What is in the data structure RT_MODEL_TEST? If there is an error_status variable, you can disable via this configuration parameter:

Thanks.

Hello,

Yes the TEST.h has a data structure such as below

/* Real-time Model Data Structure */

struct tag_RTM_TEST {

const char_T *errorStatus;

};

I have choosen below configuration

cs.set_param('SuppressErrorStatus', 'off'); % Remove error status field in real-time model data structure

Still these variables shows up in generated code. Any thoughts ?

After making the above change, what is in the data structure in TEST.h?

[Nadeem Syed]

The structure in TEST.h looks like below

/* Real-time Model Data Structure */

struct tag_RTM_TEST {

const char_T *errorStatus;

};

Are you sure SuppressErrorStatus is set to 'off'. Error Status should not be in the tag_RTM_TEST data structure when the setting is 'off'.

[Nadeem Syed]

Yes in my configuration SuppressErrorStatus is set to off. Is there any other option which I need to check ?

I will try to post a sample model with my configuration. If that will help to understand the problem.

By any chance did you try this ?

[Mark McBroom]

I am sorry. SuppressErrorStatus needs to be set to "on".

ok thanks, it worked.
