Debian 11 compilation issues

[Daniel-M]

Hi, I'm currently facing the issue where my bluetooth scanning never ends and never shows devices. I have compiled the repository for rtw89 successfully (changing the makefile as below), and have working wifi, investigating into why the bluetooth does not work [I've found a related the issue] (lwfinger/rtw89#148 (comment)) where installation of this repository is advised.

In order for make to work had to changed the Makefile's lines;

# This line
#KSRC := /lib/modules/$(KVER)/build
# Replaced with this line
KSRC := /usr/src/linux-headers-$(KVER)

And the installation worked, have working wifi.

Now. Since I have no bluetooth scanned devices, tried to install this drive but got an error trace. I'm using Debian 11 stable with the kernel

root@tethys:~/rtw89-bt# uname -r
5.10.0-23-amd64

Using GCC version

root@tethys:~/rtw89-bt# gcc --version

That's the configuration that worked on the wifi driver.

When doing make on the root of the current main branch I get the following error trace:
