error: initialization from incompatible pointer type [-Werror]

[philm001]

I am receiving this compile error in the file ioctl_cfg80211.c on line 5971.

Specifically, .del_station = cfg80211_rtw_del_station

Hi @philm001 , did you solve the problem?

... kernel version ?

Hello,

I am also receiving this error but for another pointer:

/home/MYUSERNAME/Downloads/rtl8812AU_8821AU_linux/os_dep/linux/os_intfs.c:809:2: error: initialization from incompatible pointer type [-Werror]
  .ndo_select_queue = rtw_select_queue,

Compiling on CentOS 7 with kernel version 3.10.0-514.21.1.el7.x86_64.

I get the same (originally reported) error:

This is on a Linux Min 17.3 system, which is based on Ubuntu 14.04, with

$ uname -r
3.19.0-32-generic
$ gcc --version
gcc (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4

Following the tip in Issue 176, I commented out the line EXTRA_CFLAGS += -Werror in Makefile and ran sudo make -f Makefile.dkms install again, and then it worked. Plugging in the nic, everything seems to work, and I was able to connect to the wireless network.

Confirmed. we encountered this in another fork (astsam's fork) few weeks back too, sorry for not paying attention here earlier.
