Re: [Discuss-gnuradio] Unable to build gr-wxgui on Mac OS X 10.6.1

[Bruhtesfa Ebrahim]

Hi Michael,

Yes, I came up with this post: 
(http://www.mail-archive.com/address@hidden/msg19898.html), 
where installing mesa is suggested before installing wxWidgets. It is 
not listed in the dependencies though.

That did the trick and I now installed gnuradio including gr-wxgui and 
grc, but got this warning:


*** Post-Install Message ***
Warning: python could not find the gnuradio module.
Make sure that /usr/local/lib/python2.6/site-packages is in your 
PYTHONPATH


I used the "~/.bashrc" file suggested at 
https://radioware.nd.edu/documentation/install-guides/mac-os-x/preliminaries, 
where the PYTHONPATH was set to 
/usr/local/lib/python${PYTHON_VERSION}/site-packages.

So, I could not figure out why this happened. Any suggestions?

Hi Bruh - If you installed py26-wxpython and wxWidgets from MacPorts, then as of this morning neither allow for 'universal' compilation, and wxWidgets goes so far as to enforce 32-bit only compilation.  Chances are your Mac's compiler is trying to generate 64-bit code.  Hence, the wxpython wrappers are not being found because what's installed is for the incorrect architecture.  OSX will not allow you to mix 32-bit and 64-bit code within the same program.

That said, the Wx folks have known that their products are not 64-bit compatible on OSX for along time.  The latest release of wxWidget is 64-bit compatible on OSX, but that still leaves the wxPython 64-bit OSX interface -- which is still in beta.

Putting the pieces together, I think if you reinstall all of the background dependencies for GNU Radio as 'universal' and then the wx stuff as 32-bit, then compile GNU Radio as 32-bit, then everything should work.  I think others on this list have done that in the past, maybe even commented as such on this list.

That said, I've taken over the Qt 4.6 ports on MacPorts -- which can be 64-bit -- and in the next couple of days I'll be releasing new ports that should allow for gr-qtgui to be usable on OSX.  I'll email again once that's further along.  After seeing the difference between wx and qt, I'd much prefer to use the latter.

Hope the above helps and makes sense! - MLD

I am stuck on this problem for long. So,any help will be appreciated.

I am trying to install GnuRadio on Mac OSX 10.6.1 . I have installed the prerequisites including wxWidgets and py26-wxpython using MacPorts. However, gr-wxgui and grc failed to build.  The output lines in ./configure that correspond to this problem are:

checking for Python wxWidgets wrappers >= 2.8... no
checking for Numeric Python extensions... yes
Not building component gr-wxgui.

The problem is a bit similar to the one posted on: http://www.ruby-forum.com/topic/185848#new. The solution suggested for Ubuntu Jaunty was to remove python-wxgtk2.6 and it worked. So, what can I do for MAC OS X 10.6.1 ?

Any suggestions ?
