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.

we are using pixhawk 2.4.8 and facing error in the same step from a long time, still not able to resolve it, tried with a lot of possible actions to be taken, but error is not taking a name to get resolve. Please help us out if you found out any solution for the above, Will be a great help from your side.

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.
