Question

我想与OpenCV库进行静态链接，但是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，我收到错误：

[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[3]: *** [OpenCVLinkingStatic] Error 1

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中：

#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;
}

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

我所有需要的扩展名“.a”：

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".

每次出现典型错误时，我会得到很多行：

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

collect2: error: ld returned 1 exit status"

早些时候我通过Sources建立了openCV并且标注了参数“-DBUILD_SHARED_LIBS = OFF”。
但它不起作用，但是我所有的图书馆都扩展了“.a” 我得到错误“indefined cv :: imread”和其他类似的。
如果我使用动态链接，所有工作都正常你能帮我解决这个问题吗？感谢。

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

静态链接c ++ opencv
