[Discuss-gnuradio] GNURadio Error On Mac

[Vamsi Krishna Adsumilli]

Hi

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

Executing: /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python -u /Users/vamsi/Documents/GNURadio/CompanionWorkspace/top_block.py

Traceback (most recent call last):

  File "/Users/vamsi/Documents/GNURadio/CompanionWorkspace/top_block.py", line 204, in <module>

    main()

    tb = top_block_cls()

    return map(numpy.dtype, sig)

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

Thanks
