c++ - 静态链接 C++ OpenCV

Question

我想与 OpenCV 库进行静态链接，但我遇到了一些问题。
我使用 Linux (Ubuntu)、IDE Clion、cmake 和库 OpenCV。

当我运行项目时出现错误:

[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
CMakeFiles/OpenCVLinkingStatic.dir/build.make:112: recipe for target 'OpenCVLinkingStatic' failed

make[1]: *** [CMakeFiles/OpenCVLinkingStatic.dir/rule] Error 2
Makefile:118: recipe for target 'OpenCVLinkingStatic' failed
make: *** [OpenCVLinkingStatic] Error 2

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;
}

我在终端中通过命令“sudo apt-get install libopencv-dev”安装了 openCV 库。

我有所有需要的带有扩展“.a”的实验室:

libopencv_core.a
libopencv_highgui.a
libopencv_video.a
libopencv_objdetect.a

它们位于“/usr/lib/x86_64-linux-gnu/”。

当我尝试执行命令时:

"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".

我得到很多行，每次都包含典型错误:

"/usr/lib/x86_64-linux-gnu/libopencv_core.a(persistence.cpp.o): In function
icvCloseFile(CvFileStorage*) :
(.text._ZL12icvCloseFileP13CvFileStorage+0x52): undefined reference to  gzclose

reference to  g_type_check_class_cast 
collect2: error: ld returned 1 exit status"

早些时候，我通过源和指定参数“-DBUILD_SHARED_LIBS=OFF”构建了 openCV。
但它没有用，但是我有所有扩展名为“.a”的库。
我收到错误“indefined cv::imread”和其他类似的错误。
如果我使用动态链接，则一切正常。
你能帮我解决这个问题吗？
谢谢。

通常在静态链接的情况下，Open CV 核心库需要一些 3-d 方库。例如 zlib
