"fatal error C1083: Cannot open include file: 'rt_logging.h': No such file or directory"

I have built a model in simulink and i have generated c code using ert.tlc(system target file) and when I use mex command for that generated c code that is mex model.c in order to test the generated code for errors it is showing the following error " fatal error C1083: Cannot open include file: 'rt_logging.h': No such file or directory". Solution to this problem will be very helpful

I'm getting a similar error when attempting to build in R2022b:

fatal error C1083: Cannot open include file: 'rtGetInf.h': No such file or directory

Did you find a resolution to this issue?

Hi,

I understand that you are unable to locate the ‘rt_logging.h’.

Here are the simple steps you can follow to locate your ‘rt_logging.h’:

The "rt_logging.h" file is located in MATLAB's installation directory under `<matlabroot>/rtw/c/src`

To resolve the error, copy this file from the specified directory and paste it into your project folder.

To obtain all necessary "header files" during code generation, follow these steps:

• Go to "Model Settings" in the "Modeling" tab on the taskbar.
• Access the "Code Generation" section.
• In the "Code Generation" area, under "Build Process," ensure that the "Generate Code Only" option is not selected.
• Check the option labeled "Package code and artifacts."
• Generate the code again

On following the above instructions, Simulink will create a zip file containing the code generation files and all required header files, which are stored in a separate folder.

Hope this helps!
