Re: [Discuss-gnuradio] GR 3.7.2.1 on OSX 10.8 (Mountain Lion)

[Michael Dickens]

Hi Ed - I'm glad to hear that GNU Radio 3.7.2.1 installed without issues using 
MacPorts for you. 3.7.3 was released not long ago, and contains some nice fixes 
-- especially for audio on OSX.  You can
{{{
sudo port selfupdate
sudo port upgrade outdated
}}}
to get it (and, everything else that's been updated since then).

Given the link error, it looks like PMT is not being included in the link.  I 
think this is still an issue on OSX, looking at the current 
gr-newmod/CMakeLists.txt file.  You'll want to change line 93 from:
{{{
set(GR_REQUIRED_COMPONENTS RUNTIME)
}}}
to
{{{
set(GR_REQUIRED_COMPONENTS RUNTIME PMT)
}}}
and, that might do the trick.  Hopefully that's it.  Obviously, if you need any 
other GR components you'll need them on this line too.  But, PMT is generally 
required along with RUNTIME when building on OSX (this is not the case for 
most/all Linux).

Let me know if this works for you, and I'll figure out a way to add it into 
that file appropriately. - MLD
