Re: [microblaze-uclinux] Compile loadable kernel modules

[DeviPrasad Natesan <ndprasad@xxxxxxxxx>]

This is the simple makefile i used to test modules on the microblaze
sometime back. It worked fine.

===============
CC = /home/mblaze/linux/kernel/uClinux-dist/tools/ucfront/ucfront mb-gcc

CC_OPTION = -Os -g -fomit-frame-pointer -fno-common -fno-builtin -Wall
-mno-xl-soft-mul -mxl-soft-div

LINK_OPTION = -Wl,-elf2flt

all:    test

test.o: test.c
        ${CC} ${CC_OPTION} -c -o test.o test.c

test:   test.o test.c
        ${CC} ${LINK_OPTION} -o test test.o

clean:
        rm -rf test.o test
=======================================================

I included the following header files in the test.c
#include "stdio.h"
#include "unistd.h"
#include "stdlib.h" #include "sys/syscall.h"
#include "fcntl.h"

It worked fine. Hope it helps u.
