I want to make static linking with library OpenCV, but I have some problems.
I use Linux (Ubuntu), IDE Clion, cmake and library OpenCV.
When I run project I get error:
[50%] Linking CXX executable OpenCVLinkingStatic /usr/bin/ld:
attempted static link of dynamic object `/usr/lib/x86_64-linux-gnu/libopencv_videostab.so.2.4.9'
collect2: error: ld returned 1 exit status

CMakeListst.txt:
cmake_minimum_required(VERSION 3.10)
project(OpenCVLinkingStatic)
set(CMAKE_CXX_STANDARD 11)
find_package(OpenCV REQUIRED)
set(SOURCE_FILES main.cpp)
add_executable(OpenCVLinkingStatic main.cpp)
include_directories(${OpenCV_INCLUDE_DIRS})
target_link_libraries(OpenCVLinkingStatic ${OpenCV_LIBS} "-static")
main.cpp:
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <iostream>
using namespace cv;
int main(int argc, char** argv) {
Mat image = imread("/opt/my.jpg", CV_LOAD_IMAGE_COLOR);
namedWindow("Display window", WINDOW_AUTOSIZE);
imshow("Display window", image);
waitKey(0);
return 0;
}
I installed openCV library via command "sudo apt-get install libopencv-dev" in terminal.
I have all needed labraries with expansion ".a":
libopencv_core.a
libopencv_highgui.a
libopencv_video.a
libopencv_objdetect.a
They are located in "/usr/lib/x86_64-linux-gnu/".
When I try execute command:
"gcc -static -std=c++11 main.cpp
/usr/lib/x86_64-linux-gnu/libopencv_core.a
/usr/lib/x86_64-linux-gnu/libopencv_highgui.a
/usr/lib/x86_64-linux-gnu/libopencv_video.a
/usr/lib/x86_64-linux-gnu/libopencv_objdetect.a
-lm -lpthread -lstdc++ -o MyBinary".
I get many lines containing each time typical errors:
"/usr/lib/x86_64-linux-gnu/libopencv_core.a(persistence.cpp.o): In function

Earlier I built openCV via Sources and endicated parameter "-DBUILD_SHARED_LIBS=OFF".
But it didn't work so, however I had all libraries with expansion ".a".
I got errors "indefined cv::imread" and other like this.
If I use dynamic linking all work correctly.
Can you help me resolve the problem?
Thanks.
