Re: Can't find MQ_PRIO_MAX in include

[Fabrice Boissier <fabrice.boissier@gmail.com>]

linux-libc-dev and libc6-dev already installed, and the file /usr/include/linux/mqueue.h contains MQ_PRIO_MAX and the struct mq_attr.

But the structure mq_attr in /usr/include/linux/mqueue.h is in conflict with the one declared in the /usr/include/mqueue.h (precisely in /usr/include/bits/mqueue.h that is included by /usr/include/mqueue.h)

Either MQ_PRIO_MAX and some other constants should be defined in limits.h, or struct mq_attr shouldn't be defined twice.

So a linux kernel, the match is:

/usr/include/linux/mqueue.h:#define MQ_PRIO_MAX         32768

$ dpkg -S /usr/include/linux/mqueue.h
linux-libc-dev:amd64: /usr/include/linux/mqueue.h

Ensure linux-libc-dev is installed and look for the .h in the linux/
directory.
