Linux安装Opencv详细流程以及arm移植opencv

1、Linux Ubuntu 安装 Opencv作者：Tiger （xia）1. 我们需要安装一个cmake（我这里用的是2.8.12.2版本）2. 首先下载一个cmake3. Tar zxvf cmake 的压缩报4. 进入解压的文件夹输入./bootstrap5. make6. make install7. 还需要一些库 libgtk2.0-dev build-essential pkg-config （用 apt-getinstall +对应的库）8. 在下载Opencv （我 是2.4.9版本）（默认安装在/usr/local/bin和 /usr/local/include ）$ cd O

2、penCV-2.4.9$ cmake CMakeLists.txt$ make && make install9. export LD_L I BRARY_PATH=/usr/local/lib10. 测试就加个Opencv的头文件就知道了11. pkg-config -modversion opencv12. 编译 gxx 'pkg-config opencv -libs -cflags opencv' opencv_test.c -o test注意：一定先安装gtk库再安装opencvOpencv移植编译说明：我们移植 opencv至V itop arm 板

3、，交叉编译器是arm-none-linux-gnueabi-gcc ,和arm-none-linux-gnueabi-g+opencv和cmake的安装，这里用的是图形界面安装cmake-gui来进行前面已经介绍了opencv的交叉编译。（cmake 的界面终端）sudo apt-get install cmake-qt-guitar -xzvf opencv2.4.9.tar.gz1. 安装 cmake-qt-gui2. 解压 opencv2.4.93. 对opencv的交叉编译的相关配置在点击Configure那个按钮后要选择交叉编译如图:编译 时要去掉 几个 cmake 的复选框的 BU

4、ILD_opencv_ocl 、WITH_OPENCL、WITH_TIFF选项（不去掉编译时要出错哦）。配置完成就可以 Generate 了。在Cmakecache.txt （可以修改很多配置）的属性 CMAKE_EXE_LINKER_FLAGS 中添加CMAKE_EXE_LINKER_FLAGS =-lpthread -lrt -ldl在 CMAKE_INSTALL_PREFIX:PA TH= XXXXXX（安装路径）当前面执行完以后就开始进入/home/Opencvtest/opencv-2.4.10那个文件夹 make&&makeinstall 就 ok 了如果你是修改了

5、 CMAKE_INSTALL_PREFIX:PATH就在这个属性的对应的路径下你会找到这样的目录：如图写到这里交叉编译 opencv就告一段落了 ！ ！交叉编译测试程序（测试程序用的是交叉编译的opencv库）在测试时你会发现如图的问题:rHtdell; /hf>nt/Qpen?vTe,ityTE3raqt(d»Xl; /hOftt/p#ncvTttt/T4ft£c4#fr 曾/tHme-IlpencvTejit/ArH-ZBqSbtn/drm -none- lifiux- grwejbl-ct+ Teis-tDpencv .d -a t»ti -L/lho
