build completes successfully make install puts the module into proper location.

trying to load with modprobe ends up in [root@divistacja ~]# modprobe 8822bu ; modprobe: ERROR: could not insert '8822bu': Unknown symbol in module, or unknown parameter (see dmesg)

FomalhautWeisszwerg commented 6 years ago

The fail is caused by "Unknown symbol vfs_read". Not firmware.

But vfs_read has been obsoleted since Linux-4.14 and also already obsoleted in this driver by this commit 275bd06841bf315627d140b9c763ba63b8d3327b . Note, if vfs_read remains, make fails on Linux-4.16.

I've the same issue for kernel 4.17 "8822bu: Unknown symbol vfs_read (err 0)" how can we fix it? thanks!

@helektron As I described above, there are no error on my environments.

Which distribution do you use?

helektron commented 6 years ago

Ubuntu 18.04 Kernel 4.17

FomalhautWeisszwerg commented 6 years ago

I've reproduced this "undefined reference" error on ArchLinux.

And I also revealed why this error does not occurred on Debian and Ubuntu. On Debian and Ubuntu, maintainers apply their patchs and one of patches include following section:

In short, vfs_read and some symbols are re-enabled this patch due to compatibility.

@helektron A quick hack to fix this issue is applying patch provided by Debian or Ubuntu maintainers. http://cdn-fastly.deb.debian.org/debian/pool/main/l/linux/linux_4.17~rc7-1~exp1.debian.tar.xz

Please try the commit 5e6140c4c7acb26d7c70d922f167e9131fb4b5f1
