环境在英伟达TX2上编译 mkdir build cd build cmake .. -DCMAKE_INSTALL_PREFIX=install -DBUILD_SHARED_LIBS=ON -DCMAKE_BUILD_TYPE=Release -DDEMO=OFF cmake --build . --config Release 产生的错误

树莓派4编译遇到同样的问题，不知该如何解决

[ShiqiYu]

ARM不支持AVX，所以不能用这些选项。

如何在arm下编译使用？

[ZhangYouyi]

@taotaohan 禁用avx2可以用下面两种方法：

1. 添加cmake命令参数，如下所示： cmake .. -DCMAKE_INSTALL_PREFIX=install -DBUILD_SHARED_LIBS=ON -DCMAKE_BUILD_TYPE=Release -DDEMO=OFF -DENABLE_AVX2=OFF
2. 修改CMakeLists.txt脚本 option(ENABLE_AVX2 "use avx2" ON)修改为option(ENABLE_AVX2 "use avx2" OFF)

说明：第1种方式在jetson nano jetpack 4.4平台亲测，通过。
