Hi,
I am again hit with KBUILD issue which says as shown below
/home/tmp/linux-26/include/net/inet_connection_sock.h: In function
‘inet_csk_clear_xmit_timer’:
/home/tmp/linux-26/include/net/inet_connection_sock.h:203:3: error:
‘KBUILD_MODNAME’ undeclared (first use in this function)
/home/tmp/linux-26/include/net/inet_connection_sock.h:203:3: note:
each undeclared identifier is reported only once for each function it
appears in
/home/tmp/linux-26/include/net/inet_connection_sock.h: In function
‘inet_csk_reset_xmit_timer’:
/home/tmp/linux-26/include/net/inet_connection_sock.h:219:3: error:
‘KBUILD_MODNAME’ undeclared (first use in this function)
Ideally my understanding is When a module is build KBUILD_MODNAME is
automatically updated.
But I even tried options like -D"KBUILD_MODNAME=KBUILD_STR(l2_module)"
/usr/bin/gcc -M -g -O2 -DMODULE
-D"KBUILD_MODNAME=KBUILD_STR(l2_module)" -D__KERNEL__ -DLINUX
-fno-strict-aliasing -fno-common -ffreestanding -O2 -m32
-fomit-frame-pointer -g -pipe -msoft-float
-mpreferred-stack-boundary=2 -fno-unit-at-a-time -march=i686

-m32 tmp/l2.c
/lib/modules/3.7.6.1.i686/source/include/net/inet_connection_sock.h:203:3:
error: ‘l2_module’ undeclared (first use in this function)
It says it is undeclared.
Anybody have any clue what I messed up this time ? Thanks for the last reply
Regards,
Ajith
