MATLAB I/O Server Build Failure on Raspberry Pi OS Bookworm: Missing Libcamera Header File

Hi

I encountered a build error when integrating Raspberry Pi with MATLAB. I couldn't find any similar cases, but if there's already a post about this, please let me know.

1. Issue Summary

The MATLAB I/O Server failed to build/update on the target board using the Raspberry Pi Support Package, resulting in a compilation error.

2. Environment and Version Details

Windows11home + MATLAB R2024b (Home License)　

Raspberry Pi Zero 2 W + Raspberry Pi OS Bookworm (32-bit)

Support Package ver 24.2.0

3. Error Details (Fatal Error)

The compilation terminated due to a fatal error, indicating a missing header file related to the camera library during the build process.

Excerpt from the Error Log:

LibCamera.h:26:14: fatal error: core/rpicam_app.hpp: No such file or directory

26 | #include <core/rpicam_app.hpp>

| ^~~~~~~~~~~~~~~~~~~~~

compilation terminated.

make: *** [Makefile:109: obj/customFunction.o] Error 1

Observation:

• The MATLAB Support Package documentation(2024b) states that Raspberry Pi OS Bookworm is supported.
• The error suggests the rpicam_app.hpp header file, which is part of the Libcamera/camera application development files, is missing on the system.
• The installation of any prerequisite library/package (e.g., rpicam-dev or libcamera-app) has not been performed yet.

4. Questioins

A. Given that the documentation confirms support for Raspberry Pi OS Bookworm, are users required to manually install a specific development package (such as rpicam-dev or libcamera-app) on the Raspberry Pi prior to building the I/O server? If so, please specify the exact package name required to resolve the missing header file error.

B. Have there been any similar reports of this specific compilation error (fatal error: core/rpicam_app.hpp: No such file or directory) when building on Bookworm? If so, please provide the official resolution or link to the relevant Answer.

C. I understand that Raspberry Pi OS Bullseye is no longer officially supported by the Raspberry Pi Foundation. However, concerning the MATLAB Support Package:

Does the older Bullseye release offer greater stability for the MATLAB I/O Server build and execution compared to the officially supported Bookworm release?

Switching to Bullseye did not resolve the issue. Is there a problem with the Zero 2 W?

[Prasanth Sunkara]

Hi Yosuke, could you reach out to MathWorks Technical support? They can help you investigate this issue and suggest solutions/workarounds if possible

[Yosuke Yasuda]

Thank you, I understand! I'll go ahead and ask/inquire.
