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

问题描述

我有一个自编译opencv的问题...

XUbuntu 13.10 x64
gcc version 4.8.1

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 ..

简单的例子就是工作。
我的问题是，我想在xubuntu中使用nonfree（SURF）包。

现在我想编译这些示例
http://docs.opencv.org/doc/tutorials/features2d/feature_detection/feature_detection。 html
并获得此错误（主题）

g ++ -I / usr / local / include / opencv - I / usr / local / include / opencv2 -O0 -g3
-Wall -c -fmessage-length = 0 -MMD -MP -MFexample.d-MTexample.d-o示例。 o../example.cpp完成的建筑：../ example.cpp

构建目标：SURF_Example
调用：GCC C ++链接器

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

libopencv_features2d.so.2.4：错误添加符号：命令行中缺少DSO

有任何帮助吗？

解决方案

缺少lib features2d。尝试

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

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

XUbuntu 13.10 x64 gcc version 4.8.1

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 ..

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

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" Finished building: ../example.cpp

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

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

Any help?

解决方案

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
