Ubuntu 16.04.6 building driver gives missing header file error - linux

Question

I'm trying to build my serial port USB driver from C source using makefile but when I type sudo make or sudo make install, the output is like;
sudo make
gcc -Wall -D__KERNEL__ -DMODULE
-I/lib/modules/4.15.0-45-generic/build/include -D__SMP__ -DSMP -I/usr/src/linux-4.15.0-45-generic/drivers/usb/serial/ -O -c -o ftdi_sio.o ftdi_sio.c In file included from
/lib/modules/4.15.0-45-generic/build/include/linux/kernel.h:7:0,
from ftdi_sio.c:251: /lib/modules/4.15.0-45-generic/build/include/linux/linkage.h:8:25:
fatal
error: asm/linkage.h: No such file or directory
compilation terminated. : recipe for target 'ftdi_sio.o'
failed make: *** [ftdi_sio.o] Error 1
I know asm/linkage.h file is not in include/linux directory. The problem is, how can I change the directory of given header file or how to replace header file to given directory. I'm also open for other solutions. Makefile and Rules.make files are;
Rules.make:
# -*-makefile-*-
#
# This file is part of the sample code for the book "Linux Device Drivers",
# second edition. It is meant to be generic and is designed to be recycled
# by other drivers. The comments should be clear enough.
# It partly comes from Linux Makefile, and needs GNU make. <rubini#linux.it>
# TOPDIR is declared by the Makefile including this file.
ifndef TOPDIR
TOPDIR = .
endif
# KERNELDIR can be speficied on the command line or environment
ifndef KERNELDIR
KERNELDIR := $(shell echo "/lib/modules/`uname -r`/build")
endif
# The headers are taken from the kernel
INCLUDEDIR = $(KERNELDIR)/include
# We need the configuration file, for CONFIG_SMP and possibly other stuff
# (especiall for RISC platforms, where CFLAGS depends on the exact
# processor being used).
ifeq ($(KERNELDIR)/.config,$(wildcard $(KERNELDIR))/.config)
include $(KERNELDIR)/.config
else
MESSAGE := $(shell echo "WARNING: no .config file in $(KERNELDIR)")
endif
# ARCH can be speficed on the comdline or env. too, and defaults to this arch
# Unfortunately, we can't easily extract if from kernel configuration
# (well, we could look athe asm- symlink... don't know if worth the effort)
ifndef ARCH
ARCH := $(shell uname -m | sed -e s/i.86/i386/ -e s/sun4u/sparc64/ \
-e s/arm.*/arm/ -e s/sa110/arm/)
endif

# The platform-specific Makefiles include portability nightmares.

ARCHMAKEFILE = $(TOPDIR)/Makefile.$(ARCH)
ifeq ($(ARCHMAKEFILE),$(wildcard $(ARCHMAKEFILE)))
include $(ARCHMAKEFILE)
endif

# CFLAGS: all assignments to CFLAGS are inclremental, so you can specify

#Install dir
VERSIONFILE = $(INCLUDEDIR)/linux/version.h
VERSION = $(shell awk -F\" '/REL/ {print $$2}' $(VERSIONFILE))
INSTALLDIR = /lib/modules/$(VERSION)/misc
Makefile:
# This Makefile has been simplified as much as possible, by putting all
# generic material, independent of this specific directory, into
# ../Rules.make. Read that file for details
# The usb serial headers
INCLUDEUSBSER := $(shell echo "/usr/src/linux-`uname -r`/drivers/usb/serial/")
TOPDIR := $(shell pwd)
#TOPDIR = .
include $(TOPDIR)/Rules.make
CFLAGS += -I$(INCLUDEUSBSER) -O
OBJS = ftdi.o
all: $(OBJS)
ftdi.o: ftdi_sio.o
$(LD) -r $^ -o $#
install:
install -d $(INSTALLDIR)
install -c $(OBJS) $(INSTALLDIR)
clean:
rm -f *.o *~ core
I also have ftdi_sio.c file and ftdi.sio.h file which is I think not bounded with this problem.
