问题
I could successfully implement POSIX Message Queue on Ubuntu 10.04 (Kernel version 2.6.38). But the code fails when (built and) run on same version of Ubuntu 10.04 (Kernel version 2.6.37) on ARM Processor (Thin client devices like HP T410).
The failure happens to use any of the Message Queue functions (e.g. mq_open, unlink_message_queue()) :
OSError: [Errno 38] Function not implemented
Online information shows that. POSIX MQ is supported from Linux Kernel version 2.6.6. This is very confusing to me (being new to linux world).
How come the functionality works on a x86 Linux Kernel 2.6.38 , but does not work on Kernel 2.6.37 running on ARM processor. And the document gives a different Version information 2.6.6 about the support.
Is there a better way to verify if the Current OS has the support or not ? Is it possible the Kernel is trimmed off on Thin client devices.
