Compilation failed - Githubissues

Hello, I'm trying to compile the driver on kernel 4.12.2 and I'm getting this

Do you please have any idea what is it?

Thanks!

It looks like something may have changed in kernel version 4.11. I see a few issues and comments on related driver repos etc.

Try modifying osdep_service.h as described in the following link and see if it will build then?

https://forum.manjaro.org/t/error-with-rtl8812au/24066/5

If that doesn't do it I'll dig into it a little more!

desflynn commented 6 years ago

Any update on this - did the fix above work?

xnosek00 commented 6 years ago

Hi, I had the same problem and your link helps me.

I've modified osdep_service.h and add these lines at line 23:

include <linux/version.h>

if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 11, 0)

include <linux/sched/signal.h>

endif

Now I can compile source code.

This fix is also added in rtl8192cu_fixes: https://github.com/pvaret/rtl8192cu-fixes/blob/master/include/osdep_service.h

So I can confirm, it works and you can apply patch in your repository.

Hi,

I have feedback for you. I'm using Banana pi R1 (lamobo). After instalation - there is kernel 4.9.7. Everything works with your driver and manual. I want wifi-ap a it works.

I tried to upgrade kernel. Now - there is kernel 4.13.16 and drivers does not work. Obviosly - I compiled drivers for new kernel. The same procedure. I had problem with compilation, but it reloves the post above. Module is compilled. But I can use wifi only in non AP mode. If I tried to connect to other wifi, it works. But if I tried to create host ap, I have this error report:

hostapd_setup_bss(hapd=0x972568 (wlan0), first=1) wlan0: Flushing old station entries ioctl[RTL_IOCTL_HOSTAPD]: Operation not supported wlan0: Could not connect to kernel driver wlan0: Deauthenticate all stations +rtl871x_sta_deauth_ops, ff:ff:ff:ff:ff:ff is deauth, reason=2 rtl871x_set_key_ops ioctl[RTL_IOCTL_HOSTAPD]: Operation not supported

There are some changes in this repository: https://github.com/pvaret/rtl8192cu-fixes. I tried to compile that driver, but there is the same result - AP mode does not work.

That's a pitty, because I need an access point. I can't use drivers with newer kernel. Do you have any tip, why wlan can't connect to kernel driver when using AP mode? hostapd-error-log.txt

xnosek00 commented 6 years ago

Hi,

I think, you do not have to deal with it. I tested driver on kernel 4.9.7. and AP mode is unstable. So It will be still unstable in newer kernel. No solution for this hardware :(

Does this procedure support Debian Stretch (9)?
I am getting errors with this on Raspberry Pi 3B cat /etc/os-release PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)" uname -a Linux bridge-19 4.19.42-v7+ #1219 SMP Tue May 14 21:20:58 BST 2019 armv7l GNU/Linux

I also see this error if I comment out the driver=rtl871xdrv in the hostapd.conf file:
