按照网上教程http://blog.csdn.net/w371500241/article/details/53449815安装后,运行sample里的facedetect程序时,出错,
OpenCVError: Unspecified error (The function is notimplemented. Rebuild thelibrary with Windows, GTK+ 2.x or Carbonsupport. If you are on Ubuntuor Debian, install libgtk2.0-dev andpkg-config, then re-run cmake orconfigure script) incvNamedWindow,file/home/aborn/software/OpenCV-3.0.0/modules/highgui/src/
window.cpp,line …
后经过搜索
找到如下解决方案
网上给的解释是:GTK+2.x要先于OpenCV安装(Youshould remove the currentinstallation of opencv from your system;rebuild your opencvlib
解决方法:
1.卸载opencv
直接到opencv解压目录把解压出的opencv包删掉
2.查看没安装的文件,没装的装上
安装命令:
sudoapt-get install build-essential cmake libgtk2.0-devpkg-configlibavcodec-dev libavformat-devlibswscale-dev
安装需要的包:
$sudo apt-get install build-essential
$sudo apt-get install cmake git libgtk2.0-dev pkg-configlibavcodec-dev libavformat-dev libswscale-dev
可选:也安装上
$sudo apt-get install python-dev python-numpy libtbb2 libtbb-devlibjpeg-dev libpng-dev libtiff-devlibjasper-dev libdc1394-22-dev
其中安装上述包中有未识别的名字,把中间加上空格,有可能少空格,两个名字连在一起了。
3.重新安装opencv并进行测试(2.4.9用的是可用)
$unzip opencv-3.0.0.zip
$ cd opencv-3.0.0
$mkdir build
$cd build
$cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local../
$make
$sudo make install
至此OpenCV就可以使用了
4.配置
1)
$sudo gedit /etc/ld.so.conf.d/opencv.conf
打开的文档中添加:/usr/local/lib,保存退出
$sudo ldconfig
2)
$sudo gedit /etc/bash.bashrc
打开的文档中添加:
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
exportPKG_CONFIG_PATH
保存退出
5.测试:
进入sample的c目录下,查看可运行图片即可
cd/opencv-2.4.9/samples/c
chmod+x build_all.sh
./build_all.sh
./facedetectlena.jpg
失败后先参照的网站http://blog.sina.com.cn/s/blog_96b836170102wadb.html
重新安装opencv参照的网站http://blog.csdn.net/qingyanyichen/article/details/51621982
可选包也一并安装上。
