    <p>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> <p>main.cpp</p> <p>kernel.cu</p> <p>kernel.h</p> <p>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> <pre><code>CXX=g++ CUDA_INSTALL_PATH=/usr/local/cuda CFLAGS= -I. -I$(CUDA_INSTALL_PATH)/include `pkg-config --cflags opencv` LDFLAGS= -L$(CUDA_INSTALL_PATH)/lib64 -lcudart `pkg-config --libs opencv` all: $(CXX) $(CFLAGS) -c main.cpp -o main.o nvcc $(CUDAFLAGS) -arch="sm_21" -c kernel.cu -o kernel.o $(CXX) $(LDFLAGS) main.o kernel.o -o main </code></pre> <p>I 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> <p>I have built and ran both opencv and cuda sdk samples and they worked fine separately. Can you help me?</p> <p>Here is what it returns:</p> <blockquote> <p>g++ -L/usr/local/cuda/lib64 -lcudart <code>pkg-config --libs opencv</code> main.o kernel_gpu.o -o grayscale</p> <p>main.o: In function `main':</p> <p>main.cpp:(.text+0x44): undefined reference to `cv::imread(std::basic_string, std::allocator > const&amp;, int)'</p> <p>main.cpp:(.text+0x72): undefined reference to `cv::_InputArray::_InputArray(cv::Mat const&amp;)'</p> <p>main.cpp:(.text+0xa6): undefined reference to `cv::imshow(std::basic_string, std::allocator > const&amp;, cv::_InputArray const&amp;)'</p> <p>main.cpp:(.text+0xc8): undefined reference to `cv::waitKey(int)'</p> <p>main.o: In function `cv::Mat::~Mat()':</p> <p>main.cpp:(.text._ZN2cv3MatD2Ev[_ZN2cv3MatD5Ev]+0x39): undefined reference to `cv::fastFree(void*)'</p> <p>main.o: In function `cv::Mat::release()':</p> <p>main.cpp:(.text._ZN2cv3Mat7releaseEv[cv::Mat::release()]+0x47): undefined reference to `cv::Mat::deallocate()'</p> <p>kernel_gpu.o: In function <code>cuda_BGsub': tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0x41): undefined reference to</code>cudaConfigureCall'</p> <p>kernel_gpu.o: In function <code>cuda_grayscale': tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0xb3): undefined reference to</code>cudaConfigureCall'</p> <p>kernel_gpu.o: In function <code>cuda_Filter': tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0x10d): undefined reference to</code>cudaConfigureCall'</p> <p>kernel_gpu.o: In function <code>cuda_Noise_reduc': tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0x176): undefined reference to</code>cudaConfigureCall'</p> <p>kernel_gpu.o: In function <code>cuda_RGB': tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0x1d9): undefined reference to</code>cudaConfigureCall'</p> <p>kernel_gpu.o:tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0x234): more undefined references to `cudaConfigureCall' follow</p> <p>kernel_gpu.o: In function `__cudaUnregisterBinaryUtil()':</p> <p>tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0x409): undefined reference to `__cudaUnregisterFatBinary'</p> <p>kernel_gpu.o: In function `__device_stub__Z5BGsubPhS_S_iib(unsigned char*, unsigned char*, unsigned char*, int, int, bool)':</p> <p>tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0x442): undefined reference to `cudaSetupArgument'</p> <p>tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0x465): undefined reference to `cudaSetupArgument'</p> <p>tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0x488): undefined reference to `cudaSetupArgument'</p> <p>tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0x4a7): undefined reference to `cudaSetupArgument'</p> <p>tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0x4c6): undefined reference to `cudaSetupArgument'</p> <p>kernel_gpu.o:tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0x4e5): more undefined references to `cudaSetupArgument' follow</p> <p>kernel_gpu.o: In function `<strong>sti_</strong>_cudaRegisterAll_45_tmpxft_000016bc_00000000_4_kernel_gpu_cpp1_ii_cdcbb70e()':</p> <p>tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0xe7e): undefined reference to `__cudaRegisterFatBinary'</p> <p>tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0xedc): undefined reference to `__cudaRegisterFunction'</p> <p>tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0xf29): undefined reference to `__cudaRegisterFunction'</p> <p>tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0xf76): undefined reference to `__cudaRegisterFunction'</p> <p>tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0xfc3): undefined reference to `__cudaRegisterFunction'</p> <p>tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0x1010): undefined reference to `__cudaRegisterFunction'</p> <p>kernel_gpu.o:tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text+0x105d): more undefined references to `__cudaRegisterFunction' follow</p> <p>kernel_gpu.o: In function `cudaError cudaLaunch(char*)':</p> <p>tmpxft_000016bc_00000000-1_kernel_gpu.cudafe1.cpp:(.text.<em>Z10cudaLaunchIcE9cudaErrorPT</em>[cudaError cudaLaunch(char*)]+0x14): undefined reference to `cudaLaunch'</p> <p>collect2: ld returned 1 exit status</p> <p>make: <em>*</em> [all] Error 1</p> </blockquote> <p><strong>EDIT:</strong> This version works:</p> <pre><code>CXX=g++ CUDA_INSTALL_PATH=/usr/local/cuda CFLAGS= -I. -I$(CUDA_INSTALL_PATH)/include `pkg-config --cflags opencv` LDFLAGS= -L$(CUDA_INSTALL_PATH)/lib64 -lcudart `pkg-config --libs opencv` all: $(CXX) $(CFLAGS) -c main.cpp -o main.o nvcc $(CUDAFLAGS) -arch="sm_21" -c kernel.cu -o kernel.o $(CXX) main.o `pkg-config --libs opencv` -L$(CUDA_INSTALL_PATH)/lib64 -lcudart kernel.o -o main </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
