openCV 2.4.7 添加符号时出错:命令行中缺少 DSO [英] openCV 2.4.7 error adding symbols: DSO missing from command line

问题描述

我遇到了一个自编译 opencv 的问题...

i've got a Problem with a self compiled opencv...

XUbuntu 13.10 x64gcc 版本 4.8.1

XUbuntu 13.10 x64 gcc version 4.8.1

cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -DINSTALL_C_EXAMPLES=开-D INSTALL_PYTHON_EXAMPLES=开-DBUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D WITH_OPENMP=ON ..

cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D WITH_OPENMP=ON ..

一切看起来都很好.简单的例子就可以了.我的问题是，我想在 xubuntu 中使用 nonfree(SURF) 包.

Everthing looks fine. Simple examples will be work. My problem is, i want to use the nonfree(SURF) package in xubuntu.

现在我想编译这些例子http://docs.opencv.org/doc/tutorials/features2d/feature_detection/feature_detection.html并得到这个错误(主题)

Now i want to compile these example http://docs.opencv.org/doc/tutorials/features2d/feature_detection/feature_detection.html and get this error (Topic)

g++ -I/usr/local/include/opencv -I/usr/local/include/opencv2 -O0 -g3-Wall -c -fmessage-length=0 -MMD -MP -MF"example.d" -MT"example.d" -o "example.o" "../example.cpp" 完成建筑:../example.cpp

g++ -I/usr/local/include/opencv -I/usr/local/include/opencv2 -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"example.d" -MT"example.d" -o "example.o" "../example.cpp" Finished building: ../example.cpp

构建目标:SURF_Example调用:GCC C++ 链接器

Building target: SURF_Example Invoking: GCC C++ Linker

g++ -L/usr/local/lib -o "SURF_Example" ./example.o -lopencv_core-lopencv_imgproc -lopencv_highgui -lopencv_objdetect -lopencv_nonfree

g++ -L/usr/local/lib -o "SURF_Example" ./example.o -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_objdetect -lopencv_nonfree

libopencv_features2d.so.2.4:添加符号时出错:命令行中缺少 DSO

libopencv_features2d.so.2.4: error adding symbols: DSO missing from command line

有什么帮助吗?

推荐答案

可能是链接顺序不正确，缺少lib features2d.试试

Probably, problem is in incorrect linking order and missing lib features2d. Try

g++ -L/usr/local/lib -o "SURF_Example" ./example.o -lopencv_nonfree -lopencv_objdetect -lopencv_features2d -lopencv_imgproc -lopencv_highgui -lopencv_core
