linux开发板安装opencv,Fedora 9下安装opencv for pc and for arm

cmake -DCMAKE_SYSTEM_NAME=arm-linux -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local/opencv-arm -D CMAKE_C_COMPILER=arm-linux-gcc -D CMAKE_CXX_COMPILER=arm-linux-g++ -D CMAKE_EXE_LINKER_FLAGS="-lpthread -lrt" -D WITH_TIFF=OFF ..

b，把opencv for arm的库/usr/local/opencv-arm/lib拷贝到开发板，一般拷贝到开发板的/lib目录或者/usr/lib目录。

c，编译应用程序测试：说明这里仅仅是一种编译的方法，drawing.cpp包含GUI部分，编译后放在开发板上跑不起来，所以对于GUI部分考虑先移植QT，用QT来显示。

arm-linux-g++ -I/usr/local/opencv-arm/include -L/usr/local/opencv-arm/lib -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_contrib -lopencv_legacy -lopencv_flann -lpthread -lrt drawing.cpp -o drawing

等同：下面这个使用PKG-CONFIG来管理opencv的头文件和库文件。

=============================================================

arm-linux-g++ `pkg-config --cflags --libs opencv-arm` drawing.cpp

=================================================================

d，若在开发板上运行程序，提示缺少xxopencv库，而该库已经拷贝到开发板，此种情况需要更改库的软连接，或者重命名库的名字。

ldd drawing//see the dynmic link object, drawing is a example of excutable

file drawing//see drawing's platform that is gcc build or arm-linux-gcc build.
