compile error on el7 (3.10.0-aaa.b.c)

[ElCoyote27]

Hi everyone, 4.3.8 used to compile fine on el7 but didn't work too well. I'm trying to use your branch and getting these compile errors: CC [M] /usr/src/rtl8812au/core/rtw_iol.o CC [M] /usr/src/rtl8812au/core/rtw_sreset.o CC [M] /usr/src/rtl8812au/core/rtw_btcoex.o CC [M] /usr/src/rtl8812au/core/rtw_beamforming.o CC [M] /usr/src/rtl8812au/core/rtw_odm.o CC [M] /usr/src/rtl8812au/core/efuse/rtw_efuse.o CC [M] /usr/src/rtl8812au/os_dep/osdep_service.o CC [M] /usr/src/rtl8812au/os_dep/linux/os_intfs.o /usr/src/rtl8812au/os_dep/linux/os_intfs.c:959:2: warning: initialization from incompatible pointer type [enabled by default] .ndo_select_queue = rtw_select_queue, ^ /usr/src/rtl8812au/os_dep/linux/os_intfs.c:959:2: warning: (near initialization for ‘rtw_netdev_ops..ndo_select_queue’) [enabled by default] CC [M] /usr/src/rtl8812au/os_dep/linux/usb_intf.o CC [M] /usr/src/rtl8812au/os_dep/linux/usb_ops_linux.o CC [M] /usr/src/rtl8812au/os_dep/linux/ioctl_linux.o CC [M] /usr/src/rtl8812au/os_dep/linux/xmit_linux.o CC [M] /usr/src/rtl8812au/os_dep/linux/mlme_linux.o CC [M] /usr/src/rtl8812au/os_dep/linux/recv_linux.o CC [M] /usr/src/rtl8812au/os_dep/linux/ioctl_cfg80211.o /usr/src/rtl8812au/os_dep/linux/ioctl_cfg80211.c:93:12: error: ‘IEEE80211_BAND_2GHZ’ undeclared here (not in a function) .band = IEEE80211_BAND_2GHZ, \ ^ /usr/src/rtl8812au/os_dep/linux/ioctl_cfg80211.c:151:2: note: in expansion of macro ‘CHAN2G’ CHAN2G(1, 2412, 0), ^ /usr/src/rtl8812au/os_dep/linux/ioctl_cfg80211.c:102:12: error: ‘IEEE80211_BAND_5GHZ’ undeclared here (not in a function) .band = IEEE80211_BAND_5GHZ, \ ^ /usr/src/rtl8812au/os_dep/linux/ioctl_cfg80211.c:168:2: note: in expansion of macro ‘CHAN5G’ CHAN5G(34, 0), CHAN5G(36, 0), [....]

Any ideas?

1. Checkout v4.3.21 branch.
2. Provide more information about kernel version and make options.

[ElCoyote27]

Hi Atsam, Thanks for the quick reply. I checked out v4.3.21. The OS is RHEL7 and the kernel is 3.10.0-514.6.2.el7.x86_64 Here's a log of my initial attempts: bash-4.2$ git clone https://github.com/astsam/rtl8812au.git Cloning into 'rtl8812au'... remote: Counting objects: 1262, done. remote: Compressing objects: 100% (16/16), done. remote: Total 1262 (delta 5), reused 0 (delta 0), pack-reused 1246 Receiving objects: 100% (1262/1262), 3.92 MiB | 5.36 MiB/s, done.

this one is because gcc on EL7 is gcc 4.8.5

1. Try make KSRC=/usr/src/kernels/3.10.0-514.6.2.el7.x86_64.
2. Attach file /usr/src/kernels/3.10.0-514.6.2.el7.x86_64/include/net/cfg80211.h.

[ElCoyote27]

with 'make KSRC=....' , I got the same error so I guess it's looking in the right place. That may be the fact that this enterprise kernel (el7) includes some old headers. driver v4.3.8 used to compile fine, though... Please note that RHEL7 is very similar to Centos7 (free). Attached is the file you requested.

cfg80211.h.txt

[astsam]

Thanks. Will you attach another file /usr/src/kernels/3.10.0-514.6.2.el7.x86_64/Makefile

[ElCoyote27]

Thanks to you! :) Here's the Makefile.. I'm also attaching the kernel config file for el7 ( /usr/src/kernels/3.10.0-514.6.2.el7.x86_64/.config) Makefile.txt config.txt

[astsam]

Bad news. Kernel version (accordingly Makefile) is 3.10.0, but the cfg80211 header is taken from 4.7 or higher kernel version. I see no way to adapt the driver for such deeply patched kernel. Consider to use vanilla kernel or switch to Debian, Ubuntu, Kali, Mint etc.

[LuYilei]

If we need use the CentOS version, how to resolve it. Thanks.
