build not work on fedora 33(karnel 5.8.15-301.fc33.x86_64)

I've installed the relevant ones, but no luck.

[ced@localhost rtl8821ce]$ sudo ./dkms-install.sh

I also had this error with other archlinux-based os.

Did you install the kernel headers?

[Zel9278]

yes

[tomaspinho]

Can you check their actual path in /lib/modules?

My friend had this problem, before doing this run ./dkms-remove.sh. My solution was sudo dnf install kernel-devel-$(uname -r) && sudo rm -r /lib/modules/$(uname -r)/build && sudo ln -s /usr/src/kernels/$(uname -r) /lib/modules/$(uname -r)/build. This installs the correct kernel headers for the kernel version you are on, then reinstates the broken symlink to point to the newly-installed headers.

A better solution would be to update the whole system and then build again, because I see that you have a slightly older kernel, indicative of a fresh install.

thanks! it's working
