opencv开源图像处理函数库在S3C2440移植（2）

yuyang911220

step1: 编译zlib
#tar xzf zlib-1.2.4.tar.gz
#cd zlib-1.2.4
./configure --prefix=$OPENCV_BUILD_DIR/install
#vi Makefile

替换gcc为arm-linux-gcc

替换ar为arm-linux-ar

替换ranlib为arm-linux-ranlib
#make
#make install

step2:编译jpeg库
#tar xzf jpegsrc.v8a.tar.gz
#cd jpeg-8a
./configure --host=arm-linux --prefix=$OPENCV_BUILD_DIR/install
#make
#make install

step3:编译libpng库
#tar xzf libpng-1.2.43.tar.gz
#cd libpng-1.2.43
./configure --host=arm-linux --prefix=$OPENCV_BUILD_DIR/install
#make
#make install

step4:编译OpenCV
#tar xjf OpenCV-2.0.0.tar.bz2
#cd OpenCV-2.0.0
#./configure --host=arm-linux --without-gtk --without-carbon  --without-quicktime --without-1394libs --without-ffmpeg --without-python --without-swig --disable-static --enable-shared --disable-apps CXX=arm-linux-g++  --prefix=$OPENCV_BUILD_DIR/install --libdir=$OPENCV_BUILD_DIR/install/lib -includedir=$OPENCV_BUILD_DIR/install/include
#make
#make install

最后，strip生成的库：
#find | xargs file | grep "not stripped" | cut -d: -f1 | xargs arm-linux-strip

3、编译程序编译基于openCV库的应用程序一般使用以下Makefile配合编译：注意LIBOPENCV变量的取值跟上面的一致
