TsingWei opened a new issue #16809: When build mxnet from source via cmake, if I set `USE_SSE` to `0`, target `mshadow` is still built with SSE option on. URL: https://github.com/apache/incubator-mxnet/issues/16809 ## Description When build mxnet from source via cmake, if I set `USE_SSE` to `0`, target `mshadow` is still built with SSE option on. ### Error Message ```bash [ 3%] Building CXX object CMakeFiles/mxnet_static.dir/src/c_api/c_api.cc.o /usr/bin/c++ -DDMLC_USE_CXX11 -DDMLC_USE_CXX11=1 -DMSHADOW_INT64_TENSOR_SIZE=0 -DMSHADOW_IN_CXX11 -DMSHADOW_USE_CBLAS=1 -DMSHADOW_USE_CUDA=1 -DMSHADOW_USE_CUDNN=1 -DMSHADOW_USE_F16C=0 -DMSHADOW_USE_MKL=0 -DMXNET_ENABLE_CUDA_RTC=1 -DMXNET_USE_BLAS_OPEN=1 -DMXNET_USE_CUDA=1 -DMXNET_USE_LAPACK=1 -DMXNET_USE_NCCL=0 -DMXNET_USE_NVTX=1 -DMXNET_USE_OPENCV=1 -DMXNET_USE_OPENMP=1 -DMXNET_USE_OPERATOR_TUNING=1 -DMXNET_USE_SIGNAL_HANDLER=1 -DMXNET_USE_TENSORRT=1 -DNDEBUG=1 -DONNX_NAMESPACE=onnx -DUSE_CUDNN -I/home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty/onnx-tensorrt/third_party/onnx -I/home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty/onnx-tensorrt -I/home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty -I/home/nvidia/apache-mxnet-src-1.5.1-incubating/include -I/home/nvidia/apache-mxnet-src-1.5.1-incubating/src -I/usr/local/cuda/include -I/usr/local/cuda/targets/aarch64-linux/include -I/home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty/mshadow -I/home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty/nvidia_cub -I/home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty/tvm/nnvm/include -I/home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty/tvm/include -I/home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty/dmlc-core/include -I/home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty/dlpack/include -isystem /usr/include/opencv -Wall -Wno-unknown-pragmas -Wno-sign-compare -O3 -std=c++11 -fopenmp -std=c++0x -fPIC -o CMakeFiles/mxnet_static.dir/src/c_api/c_api.cc.o -c /home/nvidia/apache-mxnet-src-1.5.1-incubating/src/c_api/c_api.cc In file included from /home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty/mshadow/mshadow/././././extension/../packet-inl.h:203:0, from /home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty/mshadow/mshadow/././././extension/implicit_gemm.h:11, from /home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty/mshadow/mshadow/./././dot_engine-inl.h:12, from /home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty/mshadow/mshadow/././expr_engine-inl.h:431, from /home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty/mshadow/mshadow/./extension.h:10, from /home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty/mshadow/mshadow/tensor.h:1054, from /home/nvidia/apache-mxnet-src-1.5.1-incubating/include/mxnet/base.h:33, from /home/nvidia/apache-mxnet-src-1.5.1-incubating/src/c_api/c_api.cc:38: /home/nvidia/apache-mxnet-src-1.5.1-incubating/3rdparty/mshadow/mshadow/././././extension/../packet/sse-inl.h:10:10: fatal error: emmintrin.h: No such file or directory #include <emmintrin.h> ``` ## To Reproduce Prepare s device without SSE support(for me it's TX2 which is aarch) and run cmake with `USE_SSE` option off. ## What have you tried to solve it? 1. add `add_definitions(-DMSHADOW_USE_SSE=0)` after line 135 https://github.com/apache/incubator-mxnet/blob/017f6fa7996048cc429b02dac9369af6778811ec/CMakeLists.txt#L135 It works but it is just a simple way. ## Environment nvidia jetson TX2, ubuntu 18.04
