PX4 building on MATLAB on Windows

Hi,

We were trying to build the Firmware for PX4 on windows. We intend to build PX4 for Pixawk 3DR with FMUV2. We have been successful in using this Autopilot on QGround Control and also were able to compile on Linux as well. However, the build on MATLAB is not going through & is giving us the following error, extracted from MW_px4_log.txt. Could anyone kindly help us resolve it ? We are using MATLAB R2022b on Windows 11 PC.

Pixhawk 3DR flight controller has been discontinued and is no longer commercially available. You can use the mRo Pixhawk instead. The main difference is that it is based on the Pixhawk FMUv3 open hardware design, which corrects a bug that limited the original Pixhawk 1 to 1MB of flash.

Did you solve the problem? I had a same outputs and I solve with some messy. But still, I'm not sure this is the right way, lol.

I just compared the 'src/lib/crypto/CMakeLists.txt'files of v1.12.3 and latest version.

Then tweaked some lines. And I could successfully build the SITL.

I hope my case can be helpful for you.

This tutorial works for me on MATLAB R2023B.

When I compiled the PC host target firmware, the process crashed. It appears that the src\lib\crypto\monocypher folder only contained the .git file. I have copied the following files https://github.com/PX4/Monocypher in this folder and now the compilation works.
