我使用 BUILD_SHARED_LIBS=0 选项在 pandaboard 上安装了带有静态链接的 opencv 。我使用的是ubuntu 11.10。我还构建了第 3 方库 png、jpeg、jasper 和 zlib。 (cmake 选项 BUILD_PNG=ON BUILD_JASPER=ON BUILD_JPEG=ON BUILD_ZLIB=ONWITH_JPEG=ONWITH_PNG=ONWITH_JASPER=ON)。我的opencv安装成功了。但是,当我编译测试程序时,我收到许多未定义的错误引用。所有这些错误似乎都与 jpeg、png 和 jasper 库有关,但我不明白为什么当我显式链接它们时 libhighgui 无法引用第 3 方库。这是我编译程序的方法:
g++ -static face_recognition.cpp -o fcarm -I/home/nandhini/opencv/2.4.2static/include/opencv -I/home/nandhini/opencv/2.4.2static/include -L/home/nandhini/opencv/2.4.2static/lib/ -L/home/nandhini/opencv/2.4.2static/share/OpenCV/3rdparty/lib -llibjpeg -llibjasper -llibpng -lzlib -lopencv_core -lopencv_contrib -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_flann -lopencv_photo -lopencv_legacy -pthread -lm -lrt -lstdc++ -ldl
我已经被这个问题困扰很长时间了,如果有人能帮助我解决这个问题,我将非常感激。请帮忙,谢谢!
