Re: [Discuss-gnuradio] GNU Radio via MacPorts Updated

[Michael Dickens]

Hi Dave - We're just discussing this issue (32-bit execution) on the MacPorts' 
lists.  The quick end-result is: With the current MacPorts' provided python2.6 
or older, the PREFER_32_BIT stuff does not work because 'python' is actually 
just a wrapper around 'exec' and the bit-preferences are no passed through.  
Apple's python2.6 -does- work, as does python2.7 and newer, because this 
command was moved to "posix_spawn"; see < 
http://www.opensource.apple.com/source/python/python-44.1/2.6/ > for the source 
code and changes Apple made (somewhere in there).

As to your actual error when running "usrp_fft.py": Apparently WX is not 
installed as 64-bit.  I haven't gotten this far in my testing (lots on my queue 
already), but my memory is that this has been an issue for a -long- time & 
still isn't resolved.  I don't remember the exact root cause any longer.

Sorry I can't be of more help yet; thanks for testing & reporting back. - MLD
