当 go 构建到链接库时，'未定义对 `cv::cuda::resize...' 的引用

Question

我在 opencv.cpp 文件中有以下代码：

#include "opencv.hpp"
#include <stdbool.h>
#include <opencv2/highgui.hpp>
#include <opencv2/imgproc.hpp>
#include <opencv2/cudawarping.hpp>
#include "opencv2/cudaimgproc.hpp"

void opencv_mat_resize(const opencv_mat src,
                       opencv_mat dst,
                       int width,
                       int height,
                       int interpolation,
                       int hardware_acceleration)
{
    if (hardware_acceleration == 0) {
        cv::resize(*static_cast<const cv::Mat*>(src),
                *static_cast<cv::Mat*>(dst),
                cv::Size(width, height),
                0,
                0,
                interpolation);
    } else {
        cv::cuda::GpuMat gpuInImage;
        cv::cuda::GpuMat gpuOutImage;

        gpuInImage.upload(*static_cast<const cv::Mat*>(src));
        cv::cuda::resize(gpuInImage, gpuOutImage, cv::Size(width, height));
        gpuOutImage.download(*static_cast<cv::Mat*>(dst));
    }
}

我曾在 golang 中使用它，如下所示：

// #cgo CFLAGS: -msse -msse2 -msse3 -msse4.1 -msse4.2 -mavx
// #cgo darwin CFLAGS: -I${SRCDIR}/deps/osx/include
// #cgo linux CFLAGS: -I${SRCDIR}/deps/linux/include
// #cgo CXXFLAGS: -std=c++11
// #cgo darwin CXXFLAGS: -I${SRCDIR}/deps/osx/include
// #cgo linux CXXFLAGS: -I${SRCDIR}/deps/linux/include
// #cgo LDFLAGS:  -lopencv_core -lopencv_imgcodecs -lopencv_imgproc -ljpeg -lpng -lwebp -lippicv -lz
// #cgo darwin LDFLAGS: -L${SRCDIR}/deps/osx/lib -L${SRCDIR}/deps/osx/share/OpenCV/3rdparty/lib
// #cgo linux LDFLAGS: -L${SRCDIR}/deps/linux/lib -L${SRCDIR}/deps/linux/share/OpenCV/3rdparty/lib
// #include "opencv.hpp"
import "C"

func (f *Framebuffer) ResizeTo(width, height int, dst *Framebuffer) error {
    if width < 1 {
        width = 1
    }

    if height < 1 {
        height = 1
    }

    err := dst.resizeMat(width, height, f.pixelType)
    if err != nil {
        return err
    }

    hardwareAcceleration := os.Getenv("RESIZE_HARDWARE_ACCELERATION")
    if enabled, err := strconv.ParseUint(hardwareAcceleration, 10, 64); err != nil || enabled == 0 {
        C.opencv_mat_resize(f.mat, dst.mat, C.int(width), C.int(height), C.CV_INTER_AREA, C.int(0))
    } else {
        C.opencv_mat_resize(f.mat, dst.mat, C.int(width), C.int(height), C.CV_INTER_AREA, C.int(1))
    }

    return nil
}

并且go build返回错误：

/etc/go/pkg/tool/linux_amd64/link: running g++ failed: exit status 1
/usr/bin/ld: /tmp/go-link-1971014753/000024.o: in function `opencv_mat_resize':
/home/andrew/source/.../opencv.cpp:187: undefined reference to `cv::cuda::resize(cv::_InputArray const&, cv::_OutputArray const&, cv::Size_<int>, double, double, int, cv::cuda::Stream&)'
collect2: error: ld returned 1 exit status

环境变量：

CPLUS_INCLUDE_PATH=/usr/local/include/opencv4:/usr/local/include/opencv4:
LD_LIBRARY_PATH=:/usr/local/cuda-11.7/lib64

在我看来，这些代码在 vscode 中没有错误报告，这意味着我的 opencv 库是正确制作的。 但我无法通过go build 。 我不明白我错过了哪里。
