[Discuss-gnuradio] Status of GNU Radio with OSX 10.9

[Michael Dickens]

Or, rather, with Apple's new libc++ runtime.  I'm working on the MacPorts 
ticket: <  https://trac.macports.org/ticket/41162 >.

The high level advice right now is: If you update to 10.9, you won't be using 
GNU Radio for a while.

It looks like there is will be 2 issues encountered when compiling GNU Radio on 
OSX 10.9 using libc++ and clang:

1) As with the ticket, there will be errors caused by something to do with 
boost.  This is typical, and we're seeing it in a bunch of other ports too 
(incuding UHD, which I have patched temporarily within MacPorts to work around 
the issue).  I'm not sure what the solution is, but it does not happen to 
everyone so it's likely the way boost is installed.

2) Even if you did get past the first boost issue, you'd get to the SWIG one, 
which isn't easily fixable -- we can't patch SWIG-generated code, since it is 
created during runtime.  The issue is that SWIG works with C++04 compliant c++ 
runtime, but not with C++11 compliant runtime, and libc++ is the latter, and 
the 2 are not totally backwards compatible.  SWIG has a ticket open at < 
http://sourceforge.net/p/swig/bugs/1331/ > with this issue since August 27, 
2013; it has LOTS of tickets open right now with various issue, and, while I'm 
sure the SWIG programmers are making progress, progress does not seem to be 
very fast.

With the above in mind, I recommend that you do NOT update to 10.9 if you're 
going to be using GNU Radio; not at this time.  I think the "best" temporary 
solution right now to get GNU Radio working with 10.9
is to uninstall -everything- from MacPorts and rebuild from go using libstdc++ 
(the default in 10.9 is to use Apple's new libc++; libstdc++ is provided by 
libgcc).  I'm not sure how to do that yet; I'll experiment & post back once 
I've figured it out. - MLD
