Opencv static library could not be linked in eclipse (-ldl is added!)

Question

I would like to link opencv statically in my c++ program so user does not have to download opencv themselves.

I have tried everything on internet to try to use opencv static library in my c++ program but it is not working.

1. I have compiled the opencv static library with -DBUILD_SHARED_LIBS=OFF to generate opencv lib files in /usr/local/lib. All of the files has .a extension. I moved these files to a folder in my program and linked it with eclipse with ("${workspace_loc:/${ProjName}/opencv lib}")

2. I have included -ljpeg -lpng -ltiff -lzlib -lpthread -lrt -ldl -lz -lm

3. I have put -static flag

4. I tried to link /usr/local/include/opencv and /usr/local/bin instead

The error message shown a bunch of code like ... sum.cpp:(.text._ZN2cv3sumERKNS_11_InputArrayE+0xb19): undefined reference to `ippicviSum_16s_C4R'

...

and

/home/vivian/cuda-workspace/AutoVideoAnalyze_v4/opencv lib/libdl.a(dlopen.o): In function dlopen': (.text+0x5): undefined reference to__dlopen' /home/vivian/cuda-workspace/AutoVideoAnalyze_v4/opencv lib/libdl.a(dlclose.o): In function dlclose': (.text+0x1): undefined reference to__dlclose' /home/vivian/cuda-workspace/AutoVideoAnalyze_v4/opencv lib/libdl.a(dlsym.o): In function dlsym': (.text+0x5): undefined reference to__dlsym' collect2: error: ld returned 1 exit status make: *** [AutoVideoAnalyze_v4] Error 1

I have tried many combination and different ways on google but nothing works. Have anyone actually linked opencv statically on their c++ program? Can you share your work please?

Answer 1

Finally linked opencv statically i eclipse! I used Opencv Cuda, IPP, ffmpeg and many other libraries so there are more libraries to include!

If you want to know what library do you need to include, you can look at the General configuration that looks like the script below (*appear when you are building opencv) and include every library in the script into the program that you want to link opencv statically.
