这个问题是编译的时候没有链接到opencv导致的。检查一下你的机器里是否安装了opencv，在编译的时候要链接到opencv

其实可以尝试使用Cmake来进行构建 会方便很多 可以参考一下本小鸭的cmakelist文件

cmake_minimum_required(VERSION 3.10)
project(myyolov5)

set(CMAKE_CXX_STANDARD 11)

set(CMAKE_BUILD_TYPE Debug)

set(CMAKE_BUILD_TYPE RelWithDebInfo)

set(OpenCV_DIR /***/*****/****/opencv-4.5.2/build)
find_package(OpenCV REQUIRED) #找OpenCV 4.5安装路径
include_directories(${OpenCV_INCLUDE_DIRS}) #加载OpenCV 4.5的头文件

set(OnnxDIR /***/*****/****/onnxruntime-linux-x64-gpu-1.10.0)
include_directories(${OnnxDIR}/include)
link_directories(${OnnxDIR}/lib)

add_executable(yolov5 main.cpp)
target_link_libraries(yolov5 ${OpenCV_LIBS})
target_link_libraries(yolov5 ${OnnxDIR}/lib/libonnxruntime.so.1.10.0)

希望能解决你的问题 其中onnxruntime可以直接下载已经编译号的版本 opencv则需要你进行下载源码进行编译
