二、opencv-2.4.1的移植过程
1、libz的交叉编译：
#CC=arm-linux-gcc ./configure --prefix=/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi --shared
#make
#make install
2、libjpeg的交叉编译：
#./configure --host=arm-linux --prefix=/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi --enable-shared --enable-static
#make install
3、libpng的交叉编译
#./configure --host=arm-linux --prefix=/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi --enable-shared --enable-static
#make
#make install
4、yasm的交叉编译:
#./configure --host=arm-linux --prefix=/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi --enable-shared --enable-static
#make
#make install
5、libx264的交叉编译:
#CC=arm-linux-gcc ./configure --enable-shared --host=arm-linux --disable-asm --prefix=/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi
#make
#make install
6、libxvid的交叉编译:
#cd build/generic
#./configure --prefix=/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi --host=arm-linux --disable-assembly
#make
#make install
7、ffmpeg的交叉编译:
#./configure --prefix=/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi --enable-shared --disable-static --enable-gpl --enable-cross-compile --arch=arm --disable-stripping --target-os=linux --enable-libx264 --enable-libxvid --cc=arm-linux-gcc --enable-swscale
#make
#make install
8、opencv2.4.1的交叉编译:
用到的主要目录说明：
交叉编译工具链所在目录 /opt/EmbedSky/4.3.3/
安装opencv的目录 /opt/EmbedSky/4.3.3/arm-none-linux-gnueabi/
opencv源码所在目录 /srv/sdk_tq2440/lib/OpenCV-2.4.1/
编译好的opencv库所在目录 /srv/sdk_tq2440/lib/OpenCV-2.4.1/build
#mkdir build
#cd build
#cmake-gui
选择源代码目录:/srv/sdk_tq2440/lib/OpenCV-2.4.1/
选择Build目录：/srv/sdk_tq2440/lib/OpenCV-2.4.1/build
点击Configure，保持generator为Unix Makefiles，选择Specify options for cross-compiling，点击Next,
Operating System填写arm-linux
C Compilers填写/opt/EmbedSky/4.3.3/bin/arm-linux-gcc
C++ Compilers填写/opt/EmbedSky/4.3.3/bin/arm-linux-g++
程序库的Target Root填写/opt/EmbedSky/4.3.3/
然后点击Finish。
修改默认配置，默认安装目录为/usr/local，为便于查找生成的库文件，把CMAKE_INSTALL_PREFIX变量改为/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi/，点击Generate生成Makefile。
#make
错误一：
Linking CXX executable ../../bin/opencv_createsamples
../../lib/libopencv_core.so: undefined reference to `clock_gettime'
../../lib/libopencv_highgui.so: undefined reference to `_TIFFerrorHandler'
../../lib/libopencv_highgui.so: undefined reference to `_TIFFrealloc'
../../lib/libopencv_core.so: undefined reference to `pthread_key_create
解决方法：
修改CMakeCache.txt，CMAKE_EXE_LINKER_FLAGS原来为空，加上-lpthread -lrt，重新编译，错误消除
错误二：
Linking CXX executable ../../bin/opencv_createsamples
../../lib/libopencv_highgui.so: undefined reference to `_TIFFerrorHandler'
../../lib/libopencv_highgui.so: undefined reference to `_TIFFrealloc'
../../lib/libopencv_highgui.so: undefined reference to `_TIFFmalloc'
../../lib/libopencv_highgui.so: undefined reference to `_TIFFmemcpy'
../../lib/libopencv_highgui.so: undefined reference to `TIFFOpen'
../../lib/libopencv_highgui.so: undefined reference to `_TIFFfree'
../../lib/libopencv_highgui.so: undefined reference to `_TIFFwarningHandler'
../../lib/libopencv_highgui.so: undefined reference to `_TIFFmemcmp'
../../lib/libopencv_highgui.so: undefined reference to `_TIFFmemset'
解决方法：修改CMakeCache.txt，WITH_TIFF:BOOL=ON，改成OFF，重新编译，错误消除。
#make install
三、测试
测试程序：
#include
#include
#include
int main(int argc,char **argv)
{
CvCapture* capture = NULL;
IplImage* frame = NULL;
if(!(capture = cvCaptureFromCAM(-1)))
{
fprintf(stderr, "Can not open camera./n");
return -1;
}
cvNamedWindow("video", 1);
while(frame = cvQueryFrame( capture ) )
{
cvShowImage("video", frame);
}
cvDestroyWindow("video");
cvReleaseCapture(&capture);
return 0;
}
编译：
＃arm-linux-g++ -o opencv_test opencv_test.cpp -I /opt/EmbedSky/4.3.3/arm-none-linux-gnueabi/include/opencv -L /opt/EmbedSky/4.3.3/arm-none-linux-gnueabi/lib -lopencv_core -lopencv_highgui -lpthread -lrt
