Compiling for android from linux with g++

I'm trying to compile .cc files for android from linux with arm-linux-androideabi-g++ tool. It includes #include<algorithm>.
When I try to compile it I get this error:
fatal error: algorithm: No such file or directory I think that I should point library headers to the compiler with -I flag, but I'm not sure what directory it should be.
Does anyone has any idea how to compile it?
I tried looking in ndk package for the header file:

./toolchains/llvm/prebuilt/linux-x86_64/lib64/clang/5.0.300080/include/cuda_wrappers/algorithm
./toolchains/llvm/prebuilt/linux-x86_64/lib64/clang/5.0/include/cuda_wrappers/algorithm
./sources/cxx-stl/llvm-libc++/include/algorithm
./sources/cxx-stl/llvm-libc++/include/experimental/algorithm
./sources/cxx-stl/stlport/stlport/algorithm
./sources/cxx-stl/gnu-libstdc++/4.9/include/algorithm
./sources/cxx-stl/gnu-libstdc++/4.9/include/ext/algorithm
./sources/cxx-stl/gnu-libstdc++/4.9/include/parallel/algorithm

I tried with these two directories: 

arm-linux-androideabi-g++ hello.cc -I/ndk/sources/cxx-stl/gnu-libstdc++/4.9/include
In file included from /ndk/sources/cxx-stl/gnu-libstdc++/4.9/include/algorithm:60:0,
     from hello.cc:1:
     /ndk/sources/cxx-stl/gnu-libstdc++/4.9/include/utility:68:28:  
     fatal error: bits/c++config.h: No such file or directory
compilation terminated.

arm-linux-androideabi-g++ hello.cc -I/ndk/sources/cxx-stl/llvm-libc++/include/
In file included from /ndk/sources/cxx-stl/llvm-libc++/include/exception:82:0,
                 from /ndk/sources/cxx-stl/llvm-libc++/include/typeinfo:61,
                 from /ndk/sources/cxx-stl/llvm-libc++/include/memory:644,
                 from /ndk/sources/cxx-stl/llvm-libc++/include/algorithm:643,
                 from hello.cc:1:
/ndk/sources/cxx-stl/llvm-libc++/include/cstdlib:114:9: error: '::strtold' has not been declared
/ndk/sources/cxx-stl/llvm-libc++/include/cstdlib:132:9: error: '::_Exit' has not been declared

What I try to do is build protobuf library for android. The build fails with missing algorithm file. This is my attempt to break it down.

You can't invoke the compilers directly with the NDK (though fixing that is on the roadmap for r19). Use a standalone toolchain or one of the supported build systems.
