MacPorts GNU Radio Changes

GNU Radio
1

As of about 2:30 PM/US/ET today, the MacPorts gnuradio ports should work
again with wx. Do {{{
sudo port selfupdate
}}} to get the latest MacPorts install and port info. Do {{{
port outdated
}}} to see what has changed, and, hopefully, some wx ports will appear;
I bypassed this step, so I’m not sure this is the case. Even if no wx
or gnuradio ports appear, you can still upgrade them manually.

The gnuradio port has 2 primary changes:

  1. It uses the new wx ports – wxPython-3.0 and py27-wxPython-3.0 –
    which are completely redesigned to handle wx more robustly than before.
    You -might- have to deactivate the prior wx ports to get everything to
    work (e.g. {{{
    sudo port -f deactivate port installed | grep wx | grep active | sed -e "s@(active)@@g"
    }}}) – it can’t hurt to do this, since the new ports actually work out
    of the box. Then, you can install the new wx ports either by
    reinstalling gnuradio, updating gnuradio, or installing them directly.

  2. As of 48fe4d89 (2013-08-27), gnuradio-devel and gnuradio-next can be
    compiled using MacPorts GCC (e.g., gcc48) – release 3.7.1 is imminent,
    and it will contain this change; release 3.6.5.1 does not contain this
    change, and I have no plans to fix it unless there is demand to do so.
    The way to use the alternative GCC is: (1) uninstall your current
    gnuradio install; (2) re-do the install, and append
    “configure.compiler=macports-gcc-4.8” to the command line. Please note
    that, currently, you’ll have to reinstall both boost and cppunit with
    the same compiler command line addition (uninstall, then reinstall as
    with gnuradio). But, once you’ve done all that, gnuradio works better
    using MacPorts GCC than it does with Apple’s GCC (or, clang, for now).

As always, if you try the above and it fails, ping me and I’ll help you
fix it. - MLD

What I wrote about installing using MacPorts’ GCC, while correct, is not
the full story regarding actually getting GNU Radio working with
MacPorts’ GCC 4.8 (or, more generally: 4.X, X >= 5). The problem is
that dependent port defaults vary somewhat, and so the install needs to
either already be done and then you go back and fix a few of the ports,
or you do it in chunks to get variants correct. I’m working on a
“script” to do this properly, but it takes quite a while to run through
so it might be a bit before it’s working with reasonable success.
If/when I get there, I’ll post it. In the meantime, feel free to email
me asking for help if you choose to go down this route. - MLD
