Re: [Discuss-gnuradio] GNU Radio in Python Tutorial - installing python block without C++
Michael, we do point out in our tutorials that you require GNU Radio 3.7.4 or later to run these tutorials. The possibility of writing Python-only OOTs is the main reason for this. However, you *probably* don't need to upgrade if you don't like. One way to do this is to clone gr-tutorial, and remove all the source files, then start adding them again as you go through the exercises.

Re: [Discuss-gnuradio] GNU Radio in Python Tutorial - installing python block without C++
Hi Martin, Thanks for the response. I'll make sure to work with the newer version going forward. I see that the tutorial home page says 3.7.4 is required, but I just checked the guided tutorial in python ( http://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorial_GNU_Radio_in_Python) and it mentions 3.7.0 or later as a prereq. Thanks again, -Mike On Wed, Oct 22, 2014 at 5:40 AM, Martin Braun martin.br...@ettus.com wrote: Michael, we do point out in our tutorials that you require GNU Radio 3.7.4 or later to run these tutorials.

Thanks for pointing that out -- definitely an annoying and nasty typo in our tutorial.
