Android build error: 'posix_memalign' was not declared in this scope

[james.withers@…]

I was compiling for Android NDK 9 and I got the following error:

gcc.compile.c++ bin.v2/libs/log/build/gcc-android4.8/release/build-no/link-static/log-api-unix/runtime-link-static/threading-multi/threadsafe_queue.o
libs/log/src/threadsafe_queue.cpp: In static member function 'static void* boost::log::v2s_mt_posix::aux::threadsafe_queue_impl::operator new(std::size_t)':
libs/log/src/threadsafe_queue.cpp:174:36: error: 'posix_memalign' was not declared in this scope
     if (posix_memalign(&p, 64, size) || !p)

I fixed the problem by changing this block in libs/log/src/threadsafe_queue.cpp from:

#if !(defined(sun) || defined(__sun)) || defined(__SunOS_5_11) || defined(__SunOS_5_12)
#define BOOST_LOG_HAS_POSIX_MEMALIGN 1
#endif

to:

#if (!defined(__ANDROID__) && !(defined(sun)) || defined(__sun)) || defined(__SunOS_5_11) || defined(__SunOS_5_12)
#define BOOST_LOG_HAS_POSIX_MEMALIGN 1
#endif
