Hello All,

I was looking for using stl maps in shared memory, when i came across Boost
library.
I have downloaded boost_1_36_0 version. In the examples directory, there is
a cpp file for sharing stl maps named doc_map.cpp.

When i compile the same with the following command:
c++ -I $BOOST_ROOT doc_map.cpp -o shmmap

I got the following errors:
/tmp/ccEYJnov.o: In function
`boost::interprocess::shared_memory_object::priv_open_or_create(boost::interprocess::detail::create_enum_t,
char const*, boost::interprocess::mode_t)':

const*)]+0x33): undefined reference to `shm_unlink'
collect2: ld returned 1 exit status

Can anyone please tell me what i'm missing in the compilation.

Thank you.
