There is a problem compiling the bootloader about arduplane-4.3.1

Works for me. I suspect you have the wrong version of gcc. You now need 10.2.1

[lixiaowei]

I’m using 10.3-2021 version

[lixiaowei]

It is normal for me to use the previous version, but there is a small error

Therefore, I have to change to the following code：

[andyp1per]

You must use the exact version supported by ardupilot.

The code above all works, why did you think you needed to change it?

[lixiaowei]

It cannot be compiled with the same gcc version

[andyp1per]

Please use the correct gcc version

I’m stuck with the same exact issue…
I’ve tried switching to python2 and verified build tools using install-prereqs-ubuntu.sh (from an updated repo).

Maybe it’s something with the empty list of GPIOs in hwdef.h?
