[B.A.T.M.A.N.] gateway_common.c:47:3: error: implicit declaration of function 'strnicmp'

[Philipp Psurek]

Hi all

Sorry if this is something You already know.

I'm on 16b4833 and try to compile the module

LANG=C make \
CONFIG_BATMAN_ADV_DEBUG=n \
CONFIG_BATMAN_ADV_BLA=y \
CONFIG_BATMAN_ADV_DAT=y \
CONFIG_BATMAN_ADV_NC=y \
CONFIG_BATMAN_ADV_MCAST=y \
KERNELPATH=/usr/src/linux-4.0.0-gentoo

and got this:

  CC [M]  /usr/src/batman-adv/gateway_common.o
/usr/src/batman-adv/gateway_common.c: In function
'batadv_parse_gw_bandwidth':
/usr/src/batman-adv/gateway_common.c:47:3: error: implicit declaration
of function 'strnicmp' [-Werror=implicit-function-declaration]
   if (strnicmp(tmp_ptr, "mbit", 4) == 0)
   ^
cc1: some warnings being treated as errors
scripts/Makefile.build:258: recipe for target
'/usr/src/batman-adv/gateway_common.o' failed
make[2]: *** [/usr/src/batman-adv/gateway_common.o] Error 1
Makefile:1390: recipe for target '_module_/usr/src/batman-adv' failed
make[1]: *** [_module_/usr/src/batman-adv] Error 2
make[1]: Leaving directory '/usr/src/linux-4.0.0-gentoo'
Makefile:53: recipe for target 'all' failed
make: *** [all] Error 2

the kernel is already compiled with this config

$ grep BATMAN .config
CONFIG_BATMAN_ADV=m
CONFIG_BATMAN_ADV_BLA=y
CONFIG_BATMAN_ADV_DAT=y
CONFIG_BATMAN_ADV_NC=y
CONFIG_BATMAN_ADV_MCAST=y
# CONFIG_BATMAN_ADV_DEBUG is not set

there was no error

also there was no error in March with 3.19.2

Again, thanx for Batman-adv

Best regards

Philipp

Please try the patches which bring batman-adv (nearly) to the same version as 
the current pre-Linux-4.1-rc1 version of batman-adv:

The first one is missing in your version to make the out-of-tree module 
compatible with Linux 4.0. The rest should not affect you.

Kind regards,
	Sven
