一个opencv的程序编译问题

shitou254

实在是搞不定。

1. 
   
2. [viewimg]$ make
   
3. gcc -o viewimg  viewimg.cpp -I/usr/include/opencv/ -L /usr/lib  -lm -lcv -lhighgui -lcvaux -Wall -g
   
4. viewimg.cpp: 在函数‘int main(int, char**)’中:
   
5. viewimg.cpp:11:19: 警告： variable ‘step’ set but not used [-Wunused-but-set-variable]
   
6. viewimg.cpp:12:15: 警告： variable ‘data’ set but not used [-Wunused-but-set-variable]
   
7. /usr/bin/ld: /tmp/ccCK5DHV.o: undefined reference to symbol 'cvReleaseImage'
   
8. /usr/bin/ld: note: 'cvReleaseImage' is defined in DSO /usr/lib/libcxcore.so.2.1 so try adding it to the linker command line
   
9. /usr/lib/libcxcore.so.2.1: could not read symbols: Invalid operation
   
10. collect2: ld 返回 1
    
11. make: *** [ALL] 错误 1

    OpenCV 我一般是这样。

1.                         <Add library="/usr/local/lib/libopencv_calib3d.so" />
   
2.                         <Add library="/usr/local/lib/libopencv_contrib.so" />
   
3.                         <Add library="/usr/local/lib/libopencv_core.so" />
   
4.                         <Add library="/usr/local/lib/libopencv_features2d.so" />
   
5.                         <Add library="/usr/local/lib/libopencv_flann.so" />
   
6.                         <Add library="/usr/local/lib/libopencv_gpu.so" />
   
7.                         <Add library="/usr/local/lib/libopencv_highgui.so" />
   
8.                         <Add library="/usr/local/lib/libopencv_imgproc.so" />
   
9.                         <Add library="/usr/local/lib/libopencv_legacy.so" />
   
10.                         <Add library="/usr/local/lib/libopencv_ml.so" />
    
11.                         <Add library="/usr/local/lib/libopencv_objdetect.so" />
    
12.                         <Add library="/usr/local/lib/libopencv_ts.so" />
    
13.                         <Add library="/usr/local/lib/libopencv_video.so" />

多加一个 -lcxcore 也许就行了……

/usr/bin/ld: /tmp/ccCK5DHV.o: undefined reference to symbol 'cvReleaseImage'
/usr/bin/ld: note: 'cvReleaseImage' is defined in DSO /usr/lib/libcxcore.so.2.1 so try adding it to the linker command line
/usr/lib/libcxcore.so.2.1: could not read symbols: Invalid operation
这提示真好……
