Build Failed : "Compilation failure for command" with PX4

Hello,
I am trying to test a flight controller algorithm on PX4 Host Target on my Simulink but I get the following error. Does anyone know the solution ?
Top model targets built:

Hi,
Here are a few things you can try to resolve the issue:
  1. Check if your model is set up correctly and all the required blocks and parameters are defined.
  2. Verify if the build folder exists and the path to that folder is correctly specified.
  3. Check if there are any errors in the MATLAB Command Window that may have caused the code generation to fail.
  4. Check if the necessary support packages and target files are installed in MATLAB. You may need to download and install the required support packages for PX4 Host Target.
  5. Try generating the code manually via the Build button in Simulink.
  6. Make sure that the cygwin path is set in MATLAB.
