本文介绍了链接Cuda在C ++问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我搜索了现有的问题，但我似乎无法解决这个问题。
我有一个blur_mask.cc文件：
#include< iostream>
#include< ctime>
#include< opencv2 / highgui / highgui.hpp>
#include< opencv2 / gpu / gpu.hpp>
#include< vector_types.h>
#include< cuda.h>
#include< cuda_runtime.h>
externCvoid gpuBlurMask（unsigned char * srcData，int srcStep，uchar3 * dst，int dstStep，int width，int height，float * mask，int maskStep，int maskWidth，int maskHeight，int blockSize = 16）;
using namespace std;
using namespace cv;
using namespace cv :: gpu;
void blurMask（Mat& src，Mat& dst，Mat& mask）{
GpuMat gpuSrc，gpuDst，gpuMask;
gpuSrc.upload（src）;
gpuDst.upload（dst）;
gpuMask.upload（mask）;
gpuBlurMask（gpuSrc.data，gpuSrc.step，gpuDst.ptr< uchar3>（），gpuDst.step，gpuSrc.cols，gpuSrc.rows，gpuMask.ptr< float>（），gpuMask。 step，gpuMask.cols，gpuMask.rows）;
gpuDst.download（dst）;
}
...
一个gpu_blur.cu文件包含
externC
void gpuBlurMask（unsigned char * srcData，int srcStep，uchar3 * dst，int dstStep，int width，int height，float * mask，int maskStep，int maskWidth，int maskHeight，int blockSize = 16）{
...
当我做
nvcc -c -o gpu_blur gpu_blur.cu
我没有错误，但在编译时
g ++ -o blur_mask blur_mask.cc gpu_blur -I / usr / local / cuda / include / -lopencv_core -lopencv_highgui -lopencv_gpu
我得到以下错误：
g ++ -o blur_mask blur_mask.cc gpu_blur - I / usr / local / cuda / include / -lopencv_core -lopencv_highgui -lopencv_gpu -lcuda

collect2：ld返回1退出状态$ b谢谢。解决方案 div> 您需要链接到cudart库（ -L / usr / local / cuda / lib64 -lcudart ）
I've searched existing questions, but I can't seem to solve this.
I have a blur_mask.cc file with:
#include <iostream>
#include <ctime>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/gpu/gpu.hpp>
#include <vector_types.h>
#include <cuda.h>
#include <cuda_runtime.h>
extern "C" void gpuBlurMask(unsigned char* srcData, int srcStep, uchar3* dst, int dstStep, int width, int height, float *mask, int maskStep, int maskWidth, int maskHeight, int blockSize=16);
using namespace std;
using namespace cv;
using namespace cv::gpu;
void blurMask(Mat& src, Mat& dst, Mat& mask) {
GpuMat gpuSrc, gpuDst, gpuMask;
gpuSrc.upload(src);
gpuDst.upload(dst);
gpuMask.upload(mask);
gpuBlurMask(gpuSrc.data, gpuSrc.step, gpuDst.ptr<uchar3>(), gpuDst.step, gpuSrc.cols, gpuSrc.rows, gpuMask.ptr<float>(), gpuMask.step, gpuMask.cols, gpuMask.rows);
gpuDst.download(dst);
}
...
And a gpu_blur.cu file that contains
extern "C"
void gpuBlurMask(unsigned char* srcData, int srcStep, uchar3* dst, int dstStep, int width, int height, float *mask, int maskStep, int maskWidth, int maskHeight, int blockSize=16) {
...
When I do
nvcc -c -o gpu_blur gpu_blur.cu
I get no errors, but when compiling
g++ -o blur_mask blur_mask.cc gpu_blur -I /usr/local/cuda/include/ -lopencv_core -lopencv_highgui -lopencv_gpu
I get the following errors:
g++ -o blur_mask blur_mask.cc gpu_blur -I /usr/local/cuda/include/ -lopencv_core -lopencv_highgui -lopencv_gpu -lcuda
