package opencv libraries with my own library

I am trying to package the opencv libraries with my own library. I do it like this:

   ar x libopencv_highgui.a
   ar x libopencv_core.a
   ar x libopencv_imgproc.a
   ar x libmyown.a
   ar cru libnew.a *.o

when I use this new library libnew.a, it comes out a lot of errors like this:

opencv_imgproc and opencv_highgui module have source files with the same names (for example, util.cpp). The object file util.o from opencv_highgui is overwritten by object file with the same name from opencv_imgproc. That's why you got link errors.

Try to use MRI script mode of AR tool. Create a MRI script file (for example, script.mri) with the following content:

create libnew.a
addlib libopencv_core.a
addlib libopencv_imgproc.a
addlib libopencv_highgui.a
addlib libmyown.a
save
end

and use it with ar tool:

ar -M <script.mri
