kaiyuyue opened a new issue #8615: the link problem of libmxnet.so URL: https://github.com/apache/incubator-mxnet/issues/8615 Dear all, This may be wired. I put the cuda, cudnn and other dependencies in a folder together. At the same time, I change their specific CLFAGS and LDFLAGS path in the Makefile. I can compile mxnet successfully. But when I do the command `ld libmxnet.so`, it shows that `undefined reference` like this: ``` ld: warning: libmklml_intel.so, needed by libmxnet.so, not found (try using -rpath or -rpath-link) ld: warning: cannot find entry symbol _start; not setting start address libmxnet.so: undefined reference to `cudnnSetLRNDescriptor' libmxnet.so: undefined reference to `cv::Mat::Mat(cv::Mat const&, cv::Rect_<int> const&)' libmxnet.so: undefined reference to `caffe::LayerParameter::LayerParameter()' libmxnet.so: undefined reference to `cv::cvtColor(cv::_InputArray const&, cv::_OutputArray const&, int, int)' libmxnet.so: undefined reference to `cudnnGetConvolutionBackwardDataWorkspaceSize' libmxnet.so: undefined reference to `google::base::CheckOpMessageBuilder::ForVar2()' libmxnet.so: undefined reference to `cudnnSetFilter4dDescriptor' libmxnet.so: undefined reference to `cv::Mat::copySize(cv::Mat const&)' libmxnet.so: undefined reference to `cudnnGetConvolutionForwardAlgorithm' libmxnet.so: undefined reference to `google::base::CheckOpMessageBuilder::CheckOpMessageBuilder(char const*)' libmxnet.so: undefined reference to `cudnnGetConvolutionBackwardFilterWorkspaceSize' libmxnet.so: undefined reference to `cudnnCreateConvolutionDescriptor' libmxnet.so: undefined reference to `cudnnDestroyConvolutionDescriptor' libmxnet.so: undefined reference to `cudnnSetTensorNdDescriptor' libmxnet.so: undefined reference to `cuLaunchKernel' libmxnet.so: undefined reference to `cudnnSetFilterNdDescriptor' libmxnet.so: undefined reference to `cudnnSoftmaxBackward' libmxnet.so: undefined reference to `caffe::LayerParameter::CopyFrom(caffe::LayerParameter const&)' libmxnet.so: undefined reference to `google::protobuf::TextFormat::PrintToString(google::protobuf::Message const&, std::string*)' ... ``` mxnet cannot work well. How to solve this? Really really thanks.
