Hi,

compilation of source code fails with some errors:

hi, which compiler (incl. version) do you use? gcc9.5 (ubuntu 22.04) is fine for me...driver for bpi-r2 internal wifi is a pain

[dto-23]

;-) ...

Using gcc 13.2.0 on Debian 6.5.3 (Kali 2023.3) ....

[frank-w]

sorry missed this issue, can you try older gcc? i do not support the r2 internal wifi driver anymore as long as i can compile it anyhow on an actual ubuntu system (currently 22.04 with gcc 11.4)

[dto-23]

Okay, thanks a lot - compilation with (Debian) gcc 11.4 works (without errors and warnings).
