移植Opencv到arm tq2440

移植opencv到tq2440一、下载opencv及cmake
1，download opencv_2.3.1
OpenCV-2.3.1a.tar.bz2
下载链接：http://opencv.org/downloads.html
2，download cmake
//cmake-3.1.0.tar.gz //without gui
cmake-3.1.0-Linux-i386.sh
下载链接：http://www.cmake.org/cmake/resources/software.html二、将下载文件放入linux下
1，cmake
文件路径
/opt/EmbedSky/cmake/cmake-3.1.0
解压
[root@EmbedSky cmake-3.1.0]# tar -xzvf cmake-3.1.0.tar.gz -C ./
2，opencv
文件路径
where is the source code:
/opt/EmbedSky/opencv_2_3_1/OpenCV-2.3.1where to build the binaries:
/opt/EmbedSky/opencv_2_3_1/opencv_forArm#./cmake-3.1.0-Linux-i386.sh#cd cmake-3.1.0-Linux-i386#cd bin#./cmake-guiwhere is the source code:/opt/EmbedSky/opencv_2_3_1/OpenCV-2.3.1where to build the binaries:/opt/EmbedSky/opencv_2_3_1/opencv_forArm然后，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 或者 Linux 注意L是大写（我用的是这个，ok的）
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++
Target Root填写/opt/EmbedSky/4.3.3
点击finish

<span style="color:#FF0000;">
小的总结
以上是用CMAKE编译OPENCV2.3.1，需要主要几个问题：
1，下载cmake和opencv，解压到linux下，这步很简单不会有什么问题
2，怎么去config cmake，最关键的
参考：http://blog.csdn.net/luotuo44/article/details/8958990
3，修改CMakeCache.txt  添加-lpthread -ldl -lrt
//Flags used by the linker.
CMAKE_EXE_LINKER_FLAGS:STRING=-lpthread -lrt -ldl
4，make && make install
5，测试应用程序
6，移植到arm
我认为如果没有必要用更高opencv的话，比如opencv2.3.1
就用opencv2.0.0
为什么推荐opencv2.0呢，很简单，
1,没有cmake，直接config...就可以了；
2，节约时间；
3，最头痛的是 遇到一大推BUG，比如出现找不到链接库，最老火的是，那库就在那儿，它还说找不到，
哈哈，如果懂修改工具链会得到解决，我遇到这个问题，网上也有人遇到这个问题
/opt/EmbedSky/4.3.3/bin/../lib/gcc/arm-none-linux-gnueabi/4.3.3/../../../../arm-none-linux-gnueabi/bin/ld:
warning: ../../lib/libopencv_imgproc.so, needed by
/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi/lib/libopencv_highgui.so,
not found (try using -rpath or -rpath-link)
/opt/EmbedSky/4.3.3/bin/../lib/gcc/arm-none-linux-gnueabi/4.3.3/../../../../arm-none-linux-gnueabi/bin/ld:
warning: ../../lib/libopencv_core.so, needed by
/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi/lib/libopencv_highgui.so,
not found (try using -rpath or -rpath-link)
下面介绍一下移植opencv2.0.0
1，下载及解压
2，生成opencv编译后的目录，方便管理
</span><h3><pre name="code" class="cpp"><span style="color:#FF0000;">#mkdir -p /opt/arm/opencv
#mkdir -p /opt/arm/opencv/lib
#mkdir -p /opt/arm/opencv/include</span>

3，执行config

#./configure --host=arm-linux --without-gtk --without-carbon --without-quicktime --without-1394libs --without-ffmpeg --without-python --without-swig --enable-static --enable-shared --disable-apps CXX=arm-linux-g++ CPPFLAGS=-I/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi/include LDFLAGS=-L/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi/libc/lib --with-v4l2 --prefix=/opt/arm/opencv --libdir=/opt/arm/opencv/lib -includedir=/opt/arm/opencv/include

分析一下命令：还是比较简单的，在执行上述命令前需要生成3个目录,见2
./configure
--host=arm-linux
--without-gtk
--without-carbon
--without-quicktime
--without-1394libs
--without-ffmpeg
--without-python
--without-swig
--enable-static
--enable-shared
--disable-apps
CXX=arm-linux-g++
CPPFLAGS=-I/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi/include
LDFLAGS=-L/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi/libc/lib
--with-v4l2
--prefix=/opt/arm/opencv
--libdir=/opt/arm/opencv/lib
-includedir=/opt/arm/opencv/include

<span style="color:#FF0000;">4，找到opencv/include/opencv目录下的cxtypes.h 第240的
“return (int)lrint(value);
”改为“return (int)(value + 0.5)即可。</span>

5，写测试应用程序，下面这个很通用，我也是在网上找的
//test.c
#include <cv.h>
#include <cxcore.h>
#include <highgui.h>

int main( int argc, char** argv )
{
//声明IplImage指针
IplImage* pFrame = NULL;

//获取摄像头
CvCapture* pCapture = cvCreateCameraCapture(-1);

//创建窗口
cvNamedWindow("video", 1);

//显示视屏
while(1)
{
      pFrame=cvQueryFrame( pCapture );
      if(!pFrame)break;
      cvShowImage("video",pFrame);
      char c=cvWaitKey(33);
      if(c==27)break;
}
cvReleaseCapture(&pCapture);
cvDestroyWindow("video");
}

6，//编译
#arm-linux-gcc test.c -o test-arm -I/opt/arm/opencv/include/opencv -L/opt/arm/opencv/lib -lml -lcvaux -lhighgui -lcv -lcxcore -lpthread -lrt

分析：
arm-linux-gcc test.c -o test-arm
-I/opt/arm/opencv/include/opencv
-L/opt/arm/opencv/lib
-lml -lcvaux -lhighgui -lcv -lcxcore -lpthread -lrt

7，移植到arm，将lib下的*.so.x，重命名后，拷贝到arm下的lib中
