Error compiling boost in android

I am trying to install boost 1.5 in android according to this .

When compiling, I get an error message. Here is a compilation error fragment:

gcc.compile.c++ bin.v2/libs/thread/build/gcc-android4.4.3/release/link-static/runtime-link-    static/threading-multi/pthread/thread.o

I found this error that I did not understand ...

./boost/thread/pthread/thread_data.hpp:42: error: 'PAGE_SIZE' was not declared in this scope. He says he has PAGE_SIZEnot been announced, but I have no idea what that means. And when I tried to look at this particular place in the code, I did not find it PAGE_SIZE.

Compilation errors like this are usually resolved by searching first on pre-processed output. Try replacing -cwith -Eand changing foo.oto foo.pp(or something else) and look at the file foo.ppfor errors (find set_stack_size).

:

        void set_stack_size(std::size_t size) BOOST_NOEXCEPT {
          if (size==0) return;
          std::size_t page_size = getpagesize();
#ifdef PTHREAD_STACK_MIN
          if (size<PTHREAD_STACK_MIN) size=PTHREAD_STACK_MIN;
#endif
          size = ((size+page_size-1)/page_size)*page_size;

getpagesize() , PAGE_SIZE. , sysconf - (tm), , getpagesize(). , -DPAGE_SIZE=2048 . , , sysconf(_SC_PAGESIZE).

1.50 boost, ndk-r8b.

:

boost/thread/thread.hpp

// Fix for missing macro
#define PAGE_SIZE sysconf(_SC_PAGESIZE)

#include <boost/thread/pthread/thread_data.hpp>

, 1.50:

boost/libs/filesystem/src/operations.cpp

# ifdef BOOST_POSIX_API

    const fs::path dot_path(".");
    const fs::path dot_dot_path("..");
#   include <sys/types.h>
