[Boost-users] Boost not compiling with arm-cross-compiler

{Ubuntu 14.04 64 bits, arm-g++ compiler 4.9 one that comes with google's ndk
r10c)
(The compiler has --sysroot pointing to platform android-14, and
-march=armv7-a)

on using arm cross-compiler for compiling boost I get the following error in
"*socket_ops.ipp*":

*<1> for all function (templates) of this type:*
template <typename SockLenType>
inline int call_getsockname(SockLenType msghdr::*,
    socket_type s, socket_addr_type* addr, std::size_t* addrlen)
{
  SockLenType tmp_addrlen = (SockLenType)*addrlen;
  int result = ::getsockname(s, addr, &tmp_addrlen);
  *addrlen = (std::size_t)tmp_addrlen;
  return result;
}

/some-path/thirdparty/boost/boost_1_55_0_Android/boost/asio/detail/impl/socket_ops.ipp:1639:
error: invalid conversion from 'int*' to 'socklen_t* {aka unsigned int*}'
[-fpermissive]
   int result = ::getsockname(s, addr, &tmp_addrlen);
                                                   ^

On changing the line to:
int result = ::getsockname(s, addr, (socklen_t*)tmp_addrlen);

it compiles fine ofcourse but i don't know if this is what is to be done.

*<2> And in "mapped_region.hpp":
/some-path/thirdparty/boost/boost_1_55_0_Android/boost/interprocess/mapped_region.hpp:49:
error: sys/shm.h: No such file or directory
 #      include <sys/shm.h>      //System V shared memory...
                                                            ^
*
and points to:
#    if defined(BOOST_INTERPROCESS_XSI_SHARED_MEMORY_OBJECTS)
#      include <sys/shm.h>      //System V shared memory...
#    endif

in that file.

Here are the flags in my user-config.jam file:

*What is the way forward for those two errors - <1> and <2> above ?*
