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)': doc_map.cpp:(.text._ZN5boost12interprocess20shared_memory_object19priv_open_or_createENS0_6detail13create_enum_tEPKcNS0_6mode_tE[boost::interprocess::shared_memory_object::priv_open_or_create(boost::interprocess::detail::create_enum_t, char const*, boost::interprocess::mode_t)]+0x163): undefined reference to `shm_open' /tmp/ccEYJnov.o: In function `boost::interprocess::detail::mutexattr_wrapper::mutexattr_wrapper(bool)': doc_map.cpp:(.text._ZN5boost12interprocess6detail17mutexattr_wrapperC1Eb[boost::interprocess::detail::mutexattr_wrapper::mutexattr_wrapper(bool)]+0x14): undefined reference to `pthread_mutexattr_init' doc_map.cpp:(.text._ZN5boost12interprocess6detail17mutexattr_wrapperC1Eb[boost::interprocess::detail::mutexattr_wrapper::mutexattr_wrapper(bool)]+0x2b): undefined reference to `pthread_mutexattr_setpshared' doc_map.cpp:(.text._ZN5boost12interprocess6detail17mutexattr_wrapperC1Eb[boost::interprocess::detail::mutexattr_wrapper::mutexattr_wrapper(bool)]+0x4d): undefined reference to `pthread_mutexattr_settype' /tmp/ccEYJnov.o: In function `boost::interprocess::detail::mutexattr_wrapper::~mutexattr_wrapper()': doc_map.cpp:(.text._ZN5boost12interprocess6detail17mutexattr_wrapperD1Ev[boost::interprocess::detail::mutexattr_wrapper::~mutexattr_wrapper()]+0xd): undefined reference to `pthread_mutexattr_destroy' /tmp/ccEYJnov.o: In function `boost::interprocess::shared_memory_object::remove(char const*)': doc_map.cpp:(.text._ZN5boost12interprocess20shared_memory_object6removeEPKc[boost::interprocess::shared_memory_object::remove(char 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.
