我在 Ubuntu 14.04 64 位桌面上使用android NDK 独立工具链编译 mxnet(v0.9.3) 合并，但遇到了一些错误。第一个错误是：
arm-linux-androideabi-g++ -std=c++11 -Wall -O3 -msse2 -Wno-unknown-pragmas -funroll-loops -Iinclude -fPIC -M -MT nnvm.o \
-I `pwd`/../ -I `pwd`/../include \
-D__MIN__=0 nnvm.cc > nnvm.d
arm-linux-androideabi-g++: error: unrecognized command line option '-msse2'
当我删除“-msse2”选项并makefile再次运行时，它可以编译更多，但后来我遇到了新的错误，例如：
jni/../mxnet_predict-all.cc:2801:37: error: 'fopen64' was not declared in this scope
jni/../mxnet_predict-all.cc:21495:14: error: 'stoi' is not a member of 'std'
jni/../mxnet_predict-all.cc:30077:52: error: 'to_string' is not a member of 'std'
jni/../mxnet_predict-all.cc:34298:29: error: 'stof' is not a member of 'std'
jni/../mxnet_predict-all.cc:41383:56: error: 'stod' is not a member of 'std'
……
我应该怎么做才能解决这些问题？
顺便说一句：我的 android-ndk 版本是 android-ndk-r13b。要创建独立工具链，我按照以下步骤操作：
$ python NDK/build/tools/make_standalone_toolchain.py --arch arm --api 21 --install-dir /tmp/my-android-toolchain
export PATH=$PATH:/tmp/my-android-toolchain/bin
export CXX=arm-linux-androideabi-g++
export CC=arm-linux-androideabi-gcc
