Issue
My last kernel development was in version 2.6~ Now I try to compile a module, and I get the following error when compiling outside the kernel tree.
/bin/sh: 1: /home/blabla/workspace/kernel35/linux-3.5/scripts/recordmcount: not found
The object file is created properly, however the problem is within the kernel Makefile itself, something has changed and I wasn't updated ?
I'm using vanilla kernel sources from kernel.org, and I already did
make oldconfig && make prepare
I posted the Makefile that I'm using, it's a standard makefile for kernel modules
# Comment/uncomment the following line to disable/enable debugging
#DEBUG = y
# Add your debugging flag (or not) to CFLAGS
ifeq ($(DEBUG),y)
DEBFLAGS = -O -g -DBLABLA_DEBUG # "-O" is needed to expand inlines
else
DEBFLAGS = -O2
endif
ccflags-y += $(DEBFLAGS)
ccflags-y += -I..
ifneq ($(KERNELRELEASE),)
# call from kernel build system
obj-m := blabla.o
else
KERNELDIR ?= /home/blabla/workspace/kernel35/linux-3.5
PWD := $(shell pwd)
default:
$(MAKE) -C $(KERNELDIR) M=$(PWD) modules
endif
clean:
rm -rf *.o *~ core .depend .*.cmd *.ko *.mod.c .tmp_versions
depend .depend dep:
$(CC) $(CFLAGS) -M *.c > .depend
ifeq (.depend,$(wildcard .depend))
include .depend
endif
Solution
OK, I figured out how to solve this. apparently, this is the first time I'm trying to compile a module without compiling the kernel beforehand. to solve the issue I run the following command from the kernel source tree.
make modules_prepare
this creates all the necessary infrastructure to support modules building.
