Make error in Ubuntu 19.04

[alac1984]

I'm trying to compile this driver in Ubuntu 19.04. make outputs an error:

/opt/rtl8188fu/os_dep/linux/os_intfs.c:956:22:` error: initialization of ‘u16 (*)(struct net_device *, struct sk_buff *, struct net_device *)’ {aka ‘short unsigned int (*)(struct net_device *, struct sk_buff *, struct net_device *)’} from incompatible pointer type ‘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 *))’} [-Werror=incompatible-pointer-types]

rtl8188fu.ko is not compiled.

Any insights?

same issue for me.

Ubuntu 18.04.3 LTS

Linux version 5.3.0-26-generic (buildd@lgw01-amd64-039) (gcc version 7.4.0 (Ubuntu 7.4.0-1ubuntu1~18.04.1)) #28~18.04.1-Ubuntu SMP Wed Dec 18 16:40:14 UTC 2019

Solution to compile in Ubuntu 19.04: Edit the Makefile in the extracted folder (~/rtl8188fu) and insert right below the 22 line (right below the EXTRA_CFLAGS += -I$(src)/hal/phydm):

EXTRA_CFLAGS += -Wno-error=incompatible-pointer-types

Save the file and compile it again.

Explanation: Kerneis above version 4.19 were altered and do not recognize the string (.ndo_select_queue = rtw_select_queue)
