I'm trying to write a C application tha run on embedded linux device (debian os). I can't create POSIX Message Queue with mq_open() method, it returns an error Function not implemented with errno. I found an answer on a forum  that I need to re-compile kernel source with enabling posix mqueue. Is it possible to adding POSIX Message Queue support to running Debian Operating System (as a kernel module), or I have to recompile kernel with CONFIG_POSIX_MQUEUE=y ?
