Re: PlutoSDR & Mac - iio block issues??

[Glen I Langston]

Hi Kevin,

I’ve run into this too.

The instructions tell you the solution after the build commands

change the “cmake” line to 
cmake -DCMAKE_INSTALL_PREFIX=/usr .
and rebuild all

and do the copy step they suggest on site

https://wiki.analog.com/resources/tools-software/linux-software/gnuradio
(Either 
cp -r /usr/local/lib/python2.7/dist-packages/gnuradio/iio 
/usr/lib/python2.7/dist-packages/gnuradio/
or
cp -r /usr/local/lib/python2.7/site-packages/gnuradio/iio 
/usr/lib/python2.7/site-packages/gnuradio/
or 
some similar combination, depending on where your build files end up after 
install
)

Good luck.

Glen

The packages can go into 4 different directories  (on Ubuntu, maybe only 2 on 
mac)

/usr/local/lib/python2.7/site-packages
/usr/lib/python2.7/site-packages

and

/usr/local/lib/python2.7/dist-packages
/usr/lib/python2.7/dist-packages

on Ubuntu

I’ve been copying all of the "site-packages" stuff into “dist-packages”
and creating symbolic link from dist-packages to site-packages.

(Not really recommended, but I do it anyway).

Good Luck
