Error in compiling boost example program using sun studio 12

Question

I am trying to compile the below example program from boost using sun studio 12 C++ compiler.
#include <boost/interprocess/shared_memory_object.hpp>
#include <boost/interprocess/mapped_region.hpp>
#include <cstring>
#include <cstdlib>
#include <string>
int main(int argc, char *argv[])
using namespace boost::interprocess;
if(argc == 1)
{  //Parent process
//Remove shared memory on construction and destruction
struct shm_remove
shm_remove() { shared_memory_object::remove("MySharedMemory"); }
~shm_remove(){ shared_memory_object::remove("MySharedMemory"); }
} remover;
//Create a shared memory object.
shared_memory_object shm (create_only, "MySharedMemory", read_write);
//Set size
shm.truncate(1000);
//Map the whole shared memory in this process
mapped_region region(shm, read_write);
//Write all the memory to 1
std::memset(region.get_address(), 1, region.get_size());
//Launch child process
std::string s(argv[0]); s += " child ";
if(0 != std::system(s.c_str()))
return 1;
else
//Open already created shared memory object.
shared_memory_object shm (open_only, "MySharedMemory", read_only);
//Map the whole shared memory in this process
mapped_region region(shm, read_only);
//Check that memory was initialized to 1
char mem = static_cast<char>(region.get_address());
for(std::size_t i = 0; i < region.get_size(); ++i)
if(*mem++ != 1)
return 1; //Error checking memory
return 0;
Using the below command :
CC -c 1.cpp -I/home/syogacha/satish/boost_1_43_0 -library=stlport4
"/home/syogacha/satish/boost_1_43_0/boost/interprocess/shared_memory_object.hpp", line 284: Error: The function "shm_open" must have a prototype.
"/home/syogacha/satish/boost_1_43_0/boost/interprocess/shared_memory_object.hpp", line 307: Error: The function "shm_unlink" must have a prototype.
"/home/syogacha/satish/boost_1_43_0/boost/interprocess/mapped_region.hpp", line 549: Error: Formal argument 1 of type char* in call to shmdt(char*) is being passed void*.
3 Error(s) detected.
I even tried to include sys/mman.h but got the same compilation errors.
Do we need to take care of few other specific things while using boost headers.
Thanks in advance ...
