I am trying to compile a project on my laptop in which I need both CUDA and opencv. So I have created 3 files<\/p>\n
In main.cpp I have opencv codes and in kernel.cu I have my kernels. I am using this makefile that I found in another project:<\/p>\n
CXX=g++\nCUDA_INSTALL_PATH=\/usr\/local\/cuda\nCFLAGS= -I. -I$(CUDA_INSTALL_PATH)\/include `pkg-config --cflags opencv`\nLDFLAGS= -L$(CUDA_INSTALL_PATH)\/lib64 -lcudart `pkg-config --libs opencv`\n\nall:\n $(CXX) $(CFLAGS) -c main.cpp -o main.o\n nvcc $(CUDAFLAGS) -arch=\"sm_21\" -c kernel.cu -o kernel.o\n $(CXX) $(LDFLAGS) main.o kernel.o -o main\n<\/code><\/pre>\nI had tried the same project on another computer with opencv 2.4.2 ,CUDA 4.0 and gcc 4.4 and it worked fine but now that I try it on my laptop with opencv 2.4.2 ,CUDA 4.2 and gcc 4.6 it keeps returning errors for the last line but it does create main.o and kernel.o and if I comment out the last line it doesn’t give error.<\/p>\n
I have built and ran both opencv and cuda sdk samples and they worked fine separately. Can you help me?<\/p>\n
