问题描述

arm-linux/bin/ld: cannot find -lopencv_imgproc

用qte编译一个opencv程序时，显示如下错误：
ligang@ligang-virtual-machine:/work/qtepro/opencv$ make
/mysoftware/qte/bin/qmake -unix -o Makefile opencv.pro
arm-linux-g++ -Wl-O1 -Wl-rpath/mysoftware/qte/lib -o opencv main.o -L/mysoftware/qte/lib -lopencv_imgproc -lopencv_core -lopencv_highgui -lopencv_ml /usr/local/lib/libopencv_core.so /usr/local/lib/libopencv_highgui.so /usr/local/lib/libopencv_imgproc.so /usr/local/lib/libopencv_ml.so -lQtNetwork -L/mysoftware/tslib/lib -L/mysoftware/qte/lib -lQtCore -lm -lrt -ldl -lpthread

配置应该都是正确的，难道是opencv的库没有头文件库吗？还是需要该它的symbollink?

解决方案

ld是连接器吧，应该是连接器没有找到库文件，你在makefile文件里面要加上库的路径才行

希望能帮到你。

解决方案二：
对应的lib库文件不在ld搜索路径中，你需要系统中找到，然后-L指定
