[求助]C++ 用到 OpenCV 库 怎么静态编译呢?

[norkki]

请问 c++用怎样正确的静态编译呢? 目的是让编译的程序不在依赖 libopencv_*.so 文件

测试代码如下:

cv-test.cc

#include <opencv2/opencv.hpp>
#include <iostream>

int main(int argc, char** argv) {
        cv::Mat image = cv::imread("image.jpg");
        if (image.empty()) {
                std::cout << "Error loading image!" << std::endl;
                return -1;
        }
        // cv::imshow("Image", image);
        std::cout << "size: "
                << image.cols << "x" << image.rows
                << std::endl;
        return 0;
}

c++ -o cv-test cv-test.cc -I/usr/local/opencv/include/opencv4/ -L/usr/local/opencv/lib64/ -lopencv_core -lopencv_imgcodecs

正常编译

加上 -static尝试静态编译 (opencv 是有编译静态库的/usr/local/opencv/lib64/libopencv_core.a)

c++ -o cv-test cv-test.cc -I/usr/local/opencv/include/opencv4/ -L/usr/local/opencv/lib64/ -lopencv_core -lopencv_imgcodecs -static

请问大佬有没有办法静态编译

虽然我不是做 c++开发的 但你或许可以试试把 OpenCV 的源码一起拉过去编译？生成的 obj 文件直接和你的程序一起编译

[frayesshi1]

全是未定义 reference ，可以反编译看看点 a 文件有没有这些函数

[Hconk]

看报错你需要加上链接 ipp 和 webp 的库，如果不需要可以重编 opencv 把这俩关掉
