HOW TO COMPILE LIBJPEG FOR ARM
------------------------------------

http://www.ijg.org/files/jpegsrc.v8d.tar.gzk
CC=arm-xxx-gcc
./configure --host=arm
make install prefix=/home/dev/linaro/people/sangwook/v4l2/fimc-v4l2-app/swlib


Sample Makefile
--------------------------------------
Thi is to link libjpeg.a

=========SAMPLE Makefile ==============

CROSS_COMPILE ?= arm-linux-gnueabi-

CC      := $(CROSS_COMPILE)gcc
CFLAGS  ?=  -Wall -I./include
LDFLAGS ?=  -static -L./lib -ljpeg

%.o : %.c
        $(CC) $(CFLAGS) -c -o $@ $<

all: v4l2_cam

v4l2_cam: v4l2_cam.o libjpeg.a
        $(CC) $(LDFLAGS) -o $@ $^ $(LIBS)

clean:
        -rm -f *.o
        -rm -f v4l2_cam
