MATLAB px4 Toolbox has build error in preparation set up

Hello, I recently updated MATLAB to R2023a version and UAV Toolbox Support Package for PX4 Autopilots to version 23.1.1.

I deleted previous PX4 folder and newly installed PX4 software as Cygwin Toolchain, which is already installed before.

After that, I do the Hardware setup as a preparation step and build error occur.

Below is the MW_px4_log.txt file content.

It seems this is internal error in your matlab toolbox code, related to the compatibility with UNIX.

Please tell me whether this is internal error or not, and if not, how can I fix this situation.

Please notice me if there are more needed information.

Thank you in advance.

Hello,

1) Can you try to build PX4 directly on Cygwin?

https://docs.px4.io/main/en/development/development.html

2) If the above does not solve your issue, please contact Technical Support with full log from the Simulink Diagnostic viewer for further investiation.

I solved the error by doing

git config --global core.autocrlf false

before git clone. Thank you for your help.

[Stefano Arrigoni]

thank you it works!!
