Hi.
Thank you for your advice.
I've checked the header files, which I include in my code for dependency
on atomic operations, and I found in
boost/interprocess/sync/interprocess_condition.hpp and
boost/interprocess/sync/interprocess_mutex.hpp
conditional dependency on file boost/interprocess/detail/atomic.hpp.
So I defined in my code BOOST_INTERPROCESS_POSIX_PROCESS_SHARED.
Since this, I don't have the error about no atomic operations for this
platform, but still have another errors concerning structure stat:

In file included
from /usr/local/arm-linux/arm-linux/include/boost/interprocess/shared_memory_object.hpp:21,
                 from Server2.cpp:3:

   function `bool 
   boost::interprocess::detail::delete_subdirectories_recursive(const 
   std::string&, const char*)':
/usr/local/arm-linux/arm-linux/include/boost/interprocess/detail/os_file_functions.hpp:515: error: `
   ::' does not have a class or union named `stat'
In file included from Server2.cpp:4:
/usr/local/arm-linux/arm-linux/include/boost/interprocess/mapped_region.hpp: In 
   constructor `boost::interprocess::mapped_region::mapped_region(const 
   MemoryMappable&, boost::interprocess::mode_t, long int, unsigned int,
const 
   void*)':
/usr/local/arm-linux/arm-linux/include/boost/interprocess/mapped_region.hpp:444: error: `
   ::' does not have a class or union named `stat'

Structure stats is defined in bits/stat.h, which is included from
sys/stat.h.
Any help will be appreciated.
Thanx.
Dundee.
