MATLAB: Is there a way to reconcile multiple rtwtypes.h files

Embedded CoderMATLABrtwtypes.h

My project has multiple independent models that are brought together into a larger application. Each model is used to generate its own code module. With that, each model generates its own rtwtypes.h file. Is there a "master" sort of rtwtypes.h that can include everything possibly generated in this file? I can't have multiple instances of this same file due to conflicting redefinition when integrating and compiling the larger app.

You can view the M file that is used to create the rtwtypes.h file by executing the following command

 >> edit([matlabroot '/toolbox/rtw/rtw/genRTWTYPESDOTH.m'])

You can see what the necessary arguments to the function are by setting a breakpoint in the M file and then generating code.

With this information, you should be able to create inputs to manually call genRTWTYPESDOTH once such that it generates one header file with all of the defined types included for your multiple models.

Alternatively, since the rtwtypes.h file is not too large and should not change, you can combine the multiple rtwtypes.h file once by hand and then always use that custom file in your larger project.

settings -> Code generation -> templated -> Generate an example main program is the correct way of disabling the generate main.

If you are looking to generate few files then please experiment with the below setting :

Code generation->Code placement->File Packaging Format

Change this from Modular to Compact

This setting will generate fewer files compare to the previous.

Please read about "File Packaging" in the documentation you your release version.

Note:

You can invoke the document for your release using the below command :

MATLAB: How to fix rtwtypes.h error

I got this error resolved after going through followed steps:

First, i checked for mex -setup which shows no compiler installed then i installed the WinGW C,C++ compiler using add on feature which mainly closed the error of compiling issue with rtwtypes.h files and other syntax error.

At this point, the error left with: gmake matlab failed with error of -2

this i resolved with the help of this answer, as my laptop not supporting the method 1,2 so i went with third method reinstalled matlab in a separate folder which name doesnot contains any spaces.

https://in.mathworks.com/matlabcentral/answers/95399-why-is-the-build-process-failing-for-a-shipped-model-in-simulink-or-for-a-model-run-in-accelerator-m

Now, the error of -2 was resolved but came up with new error stating failed to generate all binary outputs and not to read c:/users/account name(this account name has spaces in it and shows half name in the error).

I understand that matlab is not able to read my entire user account name in pc bcoz it having spaces in it. So, thought of renaming the existed user account name but after going through the reviews it states that renaming the user account name forcefully which windows10 doesnt allow will create problems in long run. Then i created a new user account in my pc with no spaces in its user name.

After this i loggined in the new user account, the run that model in simulink in new user account and finally it runned well without any errors.

Thus, finally i resolved the issue. Thanks for the staff who wrote a detailed answer in the above provided link which helped me a lot and to @Chirag who responeded in such a quick time.
