opencv-2.4.11编译备忘

编译完成后，想测试example中例子，但是由于没有sudo权限，不能运行pkg-config查看opencv的--cflags和--libs。

记录一下，备忘：

pkg-config --libs opencv
-L/usr/local/lib -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_contrib -lopencv_legacy -lopencv_flann 

pkg-config --cflags opencv
-I/usr/local/include/opencv -I/usr/local/include 

 比如，我要编译facedetect.cpp:

g++ -ggdb -I/opt/baoquanwang/third_partylib/opencv-2.4.11/include -o facedetect facedetect.cpp -L/opt/baoquanwang/third_partylib/opencv-2.4.11/lib/ -Wl,-R/opt/baoquanwang/third_partylib/opencv-2.4.11/lib/ -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_objdetect

用到哪个库最后添加哪个库即可。

测试一下：

./facedetect --cascade="../../data/haarcascades/haarcascade_frontalface_alt.xml" --nested-cascade="../../data/haarcascades/haarcascade_eye.xml" --scale=1.3 lena.jpg

我的没有桌面，没法测试……
