测试代码如下:
#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

全是未定义 reference ,可以反编译看看点 a 文件有没有这些函数

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
