Amalgamation on Android failed

[PhanTask]

Environment info

Operating System: Ubuntu 14.04 64bit Desktop

Compiler: arm-linux-androideabi-g++

MXNet version: v0.9.3

NDK vesion: android-ndk-r13b

Description

I cloned the latest version and tried amalgamation but met some troubles.
I run 'make ANDROID=1' directly and there are two errors.
First:

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'

Second:

arm-linux-androideabi-g++ -std=c++11 -Wno-unknown-pragmas -Wall -DMSHADOW_USE_CBLAS=1 -DMSHADOW_USE_SSE=0 -DMSHADOW_USE_CUDA=0 -DMSHADOW_USE_MKL=0 -DMSHADOW_RABIT_PS=0 -DMSHADOW_DIST_PS=0 -DMSHADOW_USE_SSE=0 -DDMLC_LOG_STACK_TRACE=0 -DMSHADOW_FORCE_STREAM -DMXNET_USE_OPENCV=0 -DMXNET_PREDICT_ONLY=1 -DDISABLE_OPENMP=1 -I/home/rokim/OpenBLAS -I/home/rokim/OpenBLAS/include -mhard-float -D_NDK_MATH_NO_SOFTFP=1 -O3 -fPIC -o jni_libmxnet_predict.o -c jni/predictor.cc
In file included from jni/predictor.cc:4:0:
jni/../mxnet_predict-all.cc:54:36: fatal error: src/c_api/c_api_error.cc: No such file or directory
 #include <src/c_api/c_api_error.cc>
                                    ^
compilation terminated.

I checked nnvm.d and, of course, it is empty.
Then I deleted '-msse2' option in mxnet/nnvm/amalgamation/makefile and run make clean make ANDROID=1 again, the first error is replaced by:

                 from nnvm.cc:1:
/home/rokim/mxnet/nnvm/amalgamation/../include/dmlc/./logging.h:18:22: fatal error: execinfo.h: No such file or directory
 #include <execinfo.h>

So I tried to add DEFS in mxnet/nnvm/amalgamation/makefile:

DEFS+=-DMSHADOW_USE_CUDA=0 -DMSHADOW_USE_MKL=0 -DMSHADOW_RABIT_PS=0 -DMSHADOW_DIST_PS=0 -DMSHADOW_USE_SSE=0 -DDMLC_LOG_STACK_TRACE=0 -DMSHADOW_FORCE_STREAM -DMXNET_USE_OPENCV=0 -DMXNET_PREDICT_ONLY=1 -DDISABLE_OPENMP=1
export CFLAGS = -std=c++11 -Wall -O3 -Wno-unknown-pragmas -funroll-loops -Iinclude -fPIC $(DEFS)

And I run make clean make ANDROID=1 again.
The errors mentioned above were gone, and nnvm.d is not empty, but I met some new errors like those:

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'
……

I added #define fopen64 std::fopen in mxnet_predict-all.cc and fopen64 error is gone, but I don't know how to solve others. I think this may be my NDK's problem. What should I do now?

I've attached my mxnet_predict-all.cc and nnvm.d:
mxnet_predict-all.cc.zip
nnvm.d.zip

It seems to be a GNU STL library problem. I rebuilded standalone toolchain with libc++ and compiled successfully.

[arank]

This is still an issue. When adding --stl=libc++ to the toolchain build the amalgamation build still breaks due to this existing issue with NDK (which break if you use GCC and libc++) which Google refuses to fix:

android/ndk#215

Is there any workaround to this or a WORKING way to compile the android version from source using the existing toolchain?
