Unable to compile on OSMC

[nikunjlahoti]

My primary objective is to start Soft-AP on raspberrypi2 running osmc (kernel = 4.4.16-4-osmc). I was able to start AP in Windows using the supplied CD.

modinfo r8188eu suggests that the driver is in staging. /lib/modules/4.4.16-4-osmc/kernel/drivers/staging/rtl8188eu/r8188eu.ko

sudo ln -s /usr/src/rbp2-headers-4.4.16-4-osmc /lib/modules/4.4.16-4-osmc/build sudo tar -xjvf /usr/src/rbp2-source-4.4.16-1-osmc.tar.bz2 sudo mv rbp2-source-4.4.16-1-osmc rbp2-source-4.4.16-4-osmc

(adding mach/memory.h) sudo cp -r /usr/src/rbp2-source-4.4.16-4-osmc/arch/arm/mach-bcm2709/include/mach/ /usr/src/rbp2-headers-4.4.16-4-osmc/arch/arm/include/

$ make all

make ARCH=arm CROSS_COMPILE= -C /lib/modules/4.4.16-4-osmc/build M=/home/osmc/rtl8188eu modules make[1]: Entering directory '/usr/src/rbp2-headers-4.4.16-4-osmc' CC [M] /home/osmc/rtl8188eu/core/rtw_ap.o CC [M] /home/osmc/rtl8188eu/core/rtw_br_ext.o In file included from include/linux/filter.h:16:0, from include/net/sock.h:62, from include/net/inet_sock.h:27, from include/net/ip.h:30, from /home/osmc/rtl8188eu/core/rtw_br_ext.c:23: include/net/sch_generic.h: In function ‘skb_at_tc_ingress’: include/net/sch_generic.h:414:2: error: implicit declaration of function ‘G_TC_AT’ [-Werror=implicit-function-declaration] return G_TC_AT(skb->tc_verd) & AT_INGRESS; include/net/sch_generic.h:414:33: error: ‘AT_INGRESS’ undeclared (first use in this function) return G_TC_AT(skb->tc_verd) & AT_INGRESS;

I found a similar issue at https://www.open-mesh.org/issues/246. Where the solution says "We should not compile a kernel module against kernel headers which are not meant to be used for kernel modules".

Can anyone please guide me or tell me what I am doing wrong? I am going to try it on Ubuntu later. Hopefully it will work there.

I was able to easily compile it on Ubuntu 15.04 4.2.0-35-generic. After blacklisting lsmod | grep 8188 gives correct result.

Will check if the AP capabilities work in Ubuntu and go back to raspberry pi 2.

I got it to work on Ubuntu Snappy 16.04.2! Thanks!
