Hi Vanmanh,

The error message you're encountering during the build process for a simulation target MEX-file in MATLAB indicates a problem with handling paths that contain spaces. The error NMAKE : fatal error U1073: don't know how to make 'D:\Program' suggests that the build tool (nmake, used by Visual Studio's compiler) is interpreting D:\Program Files\MATLAB\R2024a\... as D:\Program, thus getting confused because the path is split at the space character.

Hope this helps.
