Driver installation failed with gcc 11

I've been using your driver for a long time on KDE Neon but now the driver won't install anymore.

After editing the dkms-make.sh file and adding the parameter CC=/usr/bin/gcc-12 in the make command the installation becomes successful.

Hi @KaMyKaSii

Once you stretch things out, for the lack of a better way to say it, dkms will start resisting. Another way to say it is dkms checks what compiler version is used to compile the kernel and once you have a compiler that far enough behind the kernel, dkms does not like it...and for good reason. It gets hard to maintain compatibility. I'm not aware of an automatic way to fix the problem given that I try to make the drivers here compatible with as many distros as possible so...

Here is what I generally recommend as a solution:

Go to the site Main Menu:

10. How to install multiple gcc compiler versions

FYI: You won't see this if you continue to use the kernel for the distro version you are using as the devs are mindful of this. The Ubuntu devs seem to have moved from gcc 12 to gcc 13 with kernel 6.4.4 which would have triggered this.
