Can't compile

[sitaro]

Hello, on compile I got this Error:

/root/RTL88x2BU-Linux-Driver/os_dep/linux/os_intfs.c:1715:22: error: initialization of ‘u16 ()(struct net_device , struct sk_buff , struct net_device , u16 ()(struct net_device , struct sk_buff , struct net_device ))’ {aka ‘short unsigned int ()(struct net_device , struct sk_buff , struct net_device , short unsigned int ()(struct net_device , struct sk_buff , struct net_device ))’} from incompatible pointer type ‘u16 ()(struct net_device , struct sk_buff , void , u16 ()(struct net_device , struct sk_buff , struct net_device ))’ {aka ‘short unsigned int ()(struct net_device , struct sk_buff , void , short unsigned int ()(struct net_device , struct sk_buff , struct net_device ))’} [-Werror=incompatible-pointer-types] .ndo_select_queue = rtw_select_queue,

System is CentOS 8.3.2011 Compiler is gcc-8.3.1

Thanks

Hi, what is the kernel version?

[iplasma]

Have the same problem on CentOS 8 with kernel 4.18.0-240.el8.x86_64.

Looks like problem is with backport in the kernel. see discussion here. I made the changes in the patch. There is another place in rtw_android.c with a similar problem. After that, the driver compiles fine but crashed after the usb wireless dongle is plugged in. Haven't tried the driver here yet.

Seems this https://github.com/RinCat/RTL88x2BU-Linux-Driver/commit/9f94efd6b0ea7bce67781ba4a424d4d7befd2cd1, you need change 4.19 to 4.18 since this is backport.

And I cannot put this in the driver because this is distribution backport, you need find out what they did and change the preprocess kernel version.

Thanks, try your suggestion and the driver here compiles but still crashes. Switch to 5.10.4-1.el8.elrepo.x86_64 kernel from elrepo and now it works.

hi @iplasma, what configuration you used to compile with elrepo kernel? I tried, but it always fails with unavailability of kernel headers (which is not possible to install with elrepo, only using original distribution).

@RinCat Can you please check this? https://github.com/Mange/rtl8192eu-linux-driver/pull/232

It use RHEL_RELEASE_CODE to not break compilation on mainline kernels

[RinCat]

@CGarces I know that exists, but I prefer not add any distribution specific patches, as I can't check if each kernel in each distribution backports a certain patch. The easiest way is to manually modify the kernel version macro if you run into this， KERNEL_VERSION(4, 19, 0) to KERNEL_VERSION(4, 18, 0).

Success on Centos 8 (stream), as it fails to compile on default kernel what I done, first enabled elrepo repository, next installed kernel 5.4.135-1, make, make install, reboot....it works very nice. Thank you!
