Re: [Discuss-gnuradio] error while building 3.7.3 on RHEL6

[Marcus Müller]

Hi Nemanja,

that issue has been fixed in more recent GR versions (it was a
incompatibility with old Boost versions).
If you do not wish to update GNU Radio, just replace
boost::random::mt19937 by boost::mt19937 in  message_strobe_random_impl.

Greetings,
Marcus

PS: Googling for "error: ‘mt19937’ in namespace ‘boost::random’ does not
name a type" turns up my previous posts about the issue. This is really
just a friendly reminder that you should make sure that your questions
have not yet been answered before posting to the list, since this is
more often than not even faster than asking :)
