【测试成功】Fedora16下编译安装OpenCV方法

cd ~
wget http://downloads.sourceforge.net/project/opencvlibrary/opencv-unix/2.3/OpenCV-2.3.0.tar.bz2
tar -xvf OpenCV-2.3.0.tar.bz2
cd OpenCV-2.3.0/
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON ..
make

su

make install

vim /etc/ld.so.conf.d/opencv.conf

加入

/usr/local/lib

执行

ldconfig

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH

cd ~/OpenCV-2.3.0/samples/c
chmod +x build_all.sh
./build_all.sh

./facedetect --cascade="/usr/local/share/opencv/haarcascades/haarcascade_frontalface_alt.xml" --scale=1.5 lena.jpg

这时如果出现一副图片则说明OpenCV安装成功。

随便写一段代码测试

#include "cv.h" #include "highgui.h" int main() { IplImage* pImg; if((pImg = cvLoadImage("img.jpg",1))) { cvNamedWindow( "Image", 1 );//创建窗口 cvShowImage( "Image", pImg );//显示图像 cvWaitKey(0); //等待按键 cvDestroyWindow( "Image");//销毁窗口 cvReleaseImage( &pImg ); //释放图像 return 0; } return -1; }

 g++ `pkg-config --cflags --libs opencv` code.cpp -o drawing

编译运行成功！
