mkdir opencv-4.1.1/build 1. 2. 3. 4. 5. 6. 7. 8. 9. 用cmake-gui配置 在opencv-4.1.1目录下执行cmake-gui ..即可启动cmake-gui页面,开始图形化配置 我这里opencv-4.1.1文件夹的绝对路径是/home/will/opencv-4.1.1,所以下图红框1就是源码绝对路径,红框2是源码文件夹内的build子目录,配置完毕...
也可以利用pkg-config –cflags opencv和pkg-config –libs opencv这俩个来编译,一个指向头文件,一个指向lib库文件。 root@52acd6c79e97:/home/huxiang_j/work/jni/g++_opencv# g++ `pkg-config --cflags opencv` cat.cpp -o cat `pkg-config --libs opencv` root@52acd6c79e97:/home/huxiang_j/wor...
conda install --channel https://conda.anaconda.org/menpo opencv 或: sudo apt-get install libopencv-dev python-opencv 简易安装opencv3: pip install opencv-python 或: pip install opencv-python==3.1.0 简易安装方式是从库中安装编译好了的Opencv,这种安装方式简单方便,缺点是容易在使用中出现未知bug,比如...
The -shared and -pic options might also be required when you compile for some other architectures, such as ARM. You know you need these options if you get the following error when compiling OpenCV: [ 25%] Building CXX object modules/highgui/CMakeFiles/opencv_highgui.dir/src/bitstrm.cpp.o...
Ubuntu下交叉编译opencv测试程序失败,报错信息: error: opencv2/core/core_c.h: No such file or directory,在Ubuntu下编译opencv时,突然不能编译,并且报错信息如下:这让人很是费解,因为之前是编译成功过的;上网搜寻资料发现这
编译 进入opencv2.4.5所在文件夹,新建build文件夹 1 $ cd ~/opencv.2.4.8 # the directory should contain CMakeLists.txt, INSTALL etc. 2 $ mkdir build # create the output directory 3 $ cd build 4 $ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON...
1、在opencv源码根目录下创建编译目录build 2、启动cmake-gui 3、去掉with_cuda with_gtk with_1394 libv4l选项 4、配置CMAKE_INSTALL_PREFIX, 为编译后的文件安装的路径 5、点击config, 然后generate 6、进入build, 执行make 7、执行make install 至此,可以在CMAKE_INSTALL_PREFIX指定的目录下找到相关的库文件以...
sudo apt-get install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev:安装编译工具(如gcc、g++)、cmake构建系统、git版本控制工具以及用于图形界面和视频处理的开发库。 2. 下载OpenCV源代码 📥
卸载已经安装的OpenCV 先确定一下,之前是否编译过OpenCV pkg-config --modversion opencv #可查看opencv版本信息 如果没有,这步可以跳过了 先进入到安装opencv的目录,找到build文件夹 cd build sudo make uninstall cd .. sudo rm -r build rm -r /usr/local/include/opencv2 /usr/local/include/opencv /usr/...
