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:
