Re: [Discuss-gnuradio] GNURadio Error On Mac

[Vamsi Krishna Adsumilli]

Hi Micheal,

Thanks for the reply.

We were able to narrow down the issue. After generating a OOT module using gr_modtool, i have incorrectly edited the following lines, which caused the issue.

            in_sig=numpy.complex64,

            out_sig=numpy.complex64)

Where it should have been 

            in_sig=[numpy.complex64],

            out_sig=[numpy.complex64])

I faced new issues each time I restart using GNURadio on MAC, so I initially jumped to that conclusion, I’m sorry about the confusion.

Hi Vamsi - It looks like you're doing everything correctly for building & installing your OOT & GR itself.

If I had to guess, I'd think that, somehow, the 2 argument to "map" is being provided either directly or indirectly in the "top_block.py" script & clearly doesn't support iteration & needs to be able to do so. Since I don't have the code it's kinda hard to say anything more about what's going on.

I'm not sure how to test the gateway block, whatever it provides. If you can send me example code off-list I'll give it & try & see what I can do.

I’m facing the following error when I run an OOT module:

TypeError: argument 2 to map() must support iteration

I don’t have any issue running regular blocks, but not just the OOT ones.

I have installed GNURadio using Macports:

sudo port install gnuradio -universal

I use the following steps to compile the block:

mkdir build

cd build

cmake -DCMAKE_INSTALL_PREFIX=/opt/local -DPYTHON_EXECUTABLE=/opt/local/bin/python2.7 -DPYTHON_INCLUDE_DIR=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Headers -DPYTHON_LIBRARY=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Python -DGR_PYTHON_DIR=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages ../

sudo make install
