详细说明： opencv2.4.4移植到ARM 一、编译环境及库文件 linux环境：ubuntu 11.10 交叉编译：4.6.1 opencv: opencv-2.4.4 cmake: cmake-2.8.1-Linux-i386.tar.gz 二、opencv-2.4.4的移植过程 解压cmake-2.8.1-Linux-i386.tar.gz到/usr/local/ cmake-2.8.1 #export PATH= /usr/local/ cmake-2.8.1/bin:$PATH 用到的主要目录说明： 交叉编译工具链所在目录 /usr/local/arm-4.6.1/ 安装opencv的目录 /usr/local/ opencv源码所在目录 /usr/local /opencv-2.4.4 编译好的opencv库所在目录 /usr/local /opencv-2.4.4/build 默认安装目录为/usr/local #mkdir build #cd build #cmake-gui 选择源代码目录 /usr/local /opencv-2.4.4 选择Buil d目录 /usr/local /opencv-2.4.4/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/usr/local/arm-4.6.1//bin/arm-none-linux-gnueabi-gcc C++ Compilers填写/usr/local/arm-4.6.1//bin/ arm-none-linux-gnueabi -g++ 程序库的Target Root填写/usr/local/arm-4.6.1/ 然后点击Finish，开始configure 点击Generate生成Makefile（等configure完之后按钮才能点击） #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 /usr/local/include -L /usr/local/lib -lopencv_core -lopencv_highgui -lpthread -lrt ...展开收缩
