Problem with raspi() function on raspberry pi4 B

Hello,

I try to use the MATLAB Support Package for Raspberry Pi Hardware with my brand new raspberry pi 4B. I started trying to use the Mathworks raspbian image but it doesn't seems to be compatible with my board, as I get a message at boot telling me to try another OS (don't want to start). Thus I installed different OS and chose to "customize the existing operating system" option. The installation goes to the end (wiringpi library fails to install but I don't think that the error is coming from that). Then when I use the raspi() command I get the following error :

### Updating Raspberry Pi I/O server...
### Connecting to board...
### Connected to 192.168.0.35...
### Installing userland software (this might take a while)...
### Creating server folder...
### Transferring source files...
### Building MATLAB I/O server...
Error executing command "make ONLY_MATLAB_IO=1 -C /opt/MATLAB/mw_server_v20.2.0 -f Makefile". Details:

I tried with buster, bullseye and ubuntu OS and the error is the same everywhere. Am I doing something wrong or is the package not supporting PI4 B ? Thanks a lot for your help.

[Ian Field]

I'm getting the exact same error on a pi 3 B. I also used the "customize the existing operating system" option and had the wiringpi.h library fail to install.

Hi Kaoane,

I understand that you are experiencing raspi() makefile error while connecting to raspberry pi 4 board.

I can see that bcm_host.h file is missing in paticular, which is likely to cause this error. You can find solution to this from a similar example in the link below:

raspi() makefile error connecting to raspberry pi - (mathworks.com)

This is likely to resolve your issue.
