I am using a DWA-192 usb WiFi adapter in F25 hence I need to get
a driver from github to be compiled on my system so that I can use
the adapter. This driver compiled and worked quite happily with
kernel 4.9.9, not that the kernel version is necessarily an indicator
of compile success. It had been a month or more since I had apply any
system updates, so I did so two days ago, which as part of the update
updated the kernel to 4.11.5, and when dkms went to compile the
driver for the new kernel the compile failed with error messages
about implicit function definitions and messages about warnings
having been converted to errors.
That's the problem with using out-of-tree drivers. Someone has to
keep them up-to-date with kernel changes.
Does anyone know if there is an updated driver that will compile
with the current level of F25 or whether it has yet to be updated for
compatibility with F25 and hence I will need to continue to use
Ethernet internet access?
https://github.com/xxNull-lsk/rtl8812AU has a recent commit that
mentions kernel 4.11. I think
https://wikidevi.com/wiki/D-Link_DWA-192 is suggesting that you have
to modify one of the files to add your device id to it.
I downloaded the rtl8812AU driver even though its not necessarily the
right chipset (I believed the chipset in the DWA-192 was the rtl8814AU
chipset) but when I compiled it, it failed with the same errors.
It seems to me that the reason the source code is failing to compile
after the system update is that the compiler has been changed, as this
is the only reason I can see that source code that compiled fine before
the update won't compile after the update, unless the functions that the
compiler is rejecting as being implicitly defined, are functions that
were defined in the 4.9.9 kernel but have been removed sometime between
there and the 4.11.5 kernel.
I just built the driver from https://github.com/xxNull-lsk/rtl8812AU on
my machine with kernel 4.11.8-200.fc25.x86_64 with absolutely no
problem. Note that you must have the kernel-devel RPM installed, and
I'd recommend also having the elfutils-libelf-devel RPM installed.
I didn't build it for DKMS use, just the regular build:

<other stuff snipped>
I have the kernel-devel, kernel-headers and the elfutils package already
installed but it makes no difference. One thing of note with this is, I
have copied the source code to Ubuntu and the latest update has upgraded
their kernel (Ubuntu 16.10) to 4.8.8, I don't know how their kernel
numbering relates to Fedora's numbering, and it compile quite happily
via dkms. I have also tried a straight make from the source code
directory and it fails with the same errors. I have copied a snippet of
one of the errors below.
In file included from
/usr/local/downloads/dwa192/rtl8814AU-driver-4.3.21/include/drv_types.h:32:0,

^~~~~~~~~~~~
Just having a look at this error, is this because the makefile has the
-Werror parameter specified, or is it something supplied by the compiler
itself?
In the messages above I am compiling the rtl8814AU driver but the
rtl8812AU driver I downloaded is getting exactly the same errors.
It appears you're using a different driver than the 8812AU driver I
built from github at:
https://github.com/gnab/rtl8812au
Digging through the source, it appears to be v5.1.5_19247.20160830.
I included the USB device listings above. Do an "lsusb" with your
device plugged in and see if the vendor and product match one of the
entries above, e.g.:
alias: usb:v1058p0632d*dc*dsc*dp*ic*isc*ip*in*
^^^^ ^^^^
|||| ||||
|||| -------> USB Product ID
------------> USB Vendor ID
Perhaps it'll match up.
That all being said, I pulled down your driver (the rtl8814AU) version
from
https://github.com/diederikdehaas/rtl8814AU
and built it. There is a bug in one of the header files. If you want
to fix it, go into your
/usr/local/downloads/dwa192/rtl8814AU-driver-4.3.21/include
directory and edit the "osdep_service_linux.h" file. Go down to line
59 or so and insert the following lines BELOW the line that reads
"#include <linux/vmalloc.h>"
#if (LINUX_VERSION_CODE >= KERNEL_VERSION(4, 11, 0))
#include <linux/sched/signal.h>
#endif
This adds the definition of the functions that the compiler is bitching
about. Then try "make" again. Worked for me:
[rick@prophead rtl8814AU-driver-4.3.21]$ modinfo 8814au.ko

I apologise for sending my response directly to you Rick, it appears
that I used reply instead of reply-list.
I did the changes you suggested to my source code and the code did
compile successfully, so I copied that code to the source location for
dkms to pick it up from, and ran the dkms autoinstall process and it was
compiled and built into the kernel successfully, and I now have wireless
access back again.
Thankyou for all your help.
Just one question on this, with all the include files that are in that
source, how did you find that what you have provided the solution for
was the issue and what the needed include was and where it should be placed?
regards,
Steve
