nickhansenrf's questions

I'm using a program called gnuradio-companion. If I start it without root privileges, I can't save anything because I don't have read/write privileges. It gives:

/usr/lib/python2.7/dist-packages/gnuradio/grc/gui/FileDialogs.py:102: GtkWarning: Failed to read filechooser settings from "/home/nick/.config/gtk-2.0/gtkfilechooser.ini": Permission denied

If I start it with

sudo gnuradio-companion

then I'm abusing sudo, and also I get

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'

because I lose the runtime variable XDG_RUNTIME_DIR. I can use

sudo -E

to preserve environment variables but then I get

QStandardPaths: wrong ownership on runtime directory /run/user/1000, 1000 instead of 0

I guess because I'm just borrowing root privileges. Using sudo visudo to modify runtime environments gives the same thing.

How should I configure read/write privileges and run time environments to resolve this?

Ettus research gives a big list of dependencies for 18.04 which almost works for compiling gnu radio from source.

cmake gives the following config error:

-- Python checking for PyQt5 - found
-- Checking for module 'Qt5Qwt6'
--   No package 'Qt5Qwt6' found
-- QWT Version: 6.1.3
-- Found Qwt: /usr/lib/libqwt.so  

However based on the packages I have (seems like every possible version.. perhaps too many) I should have what it needs.

apt-cache search qwt

How can I edit the cmake list to properly find what it's looking for?
