WHy genFASTCC does not work ?

hi . I am trying to do the

Reverse-Capable Motion Planning for Tractor-Trailer Model Using plannerControlRRT

and the genFASTcc doent work . I got an error everytime i am trying to work it : Error using codegen.Error in genFastCC (line 13)

codegen('exampleHelperCollisionChecker', '-args', args);

pls help me , its for my thesis and IDK what to do.

How are you implementing it? It seems to work here until it needs to open the Editor and cannot (because that does not work here).

openExample('nav/TractorTrailerPlanningUsingPlannerControlRRTExample')

Error using edit
Failed to open MATLAB Editor.

Error in openExample (line 88)
edit(fullfile(workDir, mainFile))

Caused by:
Error using assert
Timeout occurred while waiting for AppContainer to return an AppState of RUNNING.

(I do not have the Navigation Toolbox, so I cannot experiment with this anywhere else.)

Hello Cristina-Rebeca,

I understand that you are trying to reproduce the MATLAB Example titled “Reverse-Capable Motion Planning for Tractor-Trailer Model Using plannerControlRRT” and you are getting an error while running the "genFASTcc.m” file that creates a MEX file using Codegen. You want to understand the cause of the issue and get a fix for it.

• The error in the file "genFASTcc.m” occurs when trying to create the MEX file using Codegen. A possible reason for the error could be an absence of the pre-requisite products to generate C and C++ code using MATLAB Coder. Make sure you have the following products installed on your device:
• MATLAB Coder
• C or C++ compiler – MinGW (Windows), GCC (Linux), Xcode (Mac). Check the list of compatible compilers on the following link - https://www.mathworks.com/support/requirements/supported-compilers.html
• Another error that can occur during MEX file generation is incompatibility of your current toolchain with SIMD 'SSE2' intrinsics. This can be fixed by installing a compiler like Microsoft Visual C++ that is compatible with the intrinsics. Refer to the following MATLAB Answers post - https://www.mathworks.com/matlabcentral/answers/2047772-error-when-using-embedded-coder-in-simulink-toolchain-lcc-win64-v2-4-1-gmake-64-bit-windows

A MATLAB Coder Error Report is generated whenever code generation fails. Please refer to the Error Report to pinpoint the reason behind the error.

For further understanding on MATLAB Coder and code generation, you can refer to the following MATLAB Documentation:

1. Documentation to install, configure and start using MATLAB Coder - https://www.mathworks.com/help/releases/R2023a/coder/getting-started-with-matlab-coder.html
2. A guide to Code Generation errors - https://www.mathworks.com/help/releases/R2023a/fixedpoint/ug/fixing-errors-detected-at-code-generation-time.html

I hope you find the above explanation and suggestions useful!
