running gnuradio-companion

[cgcgcg@…]

i installed gnuradio on an almost virgin macmini running Mountain Lion through macports with no errors.
then i installed ​gqrx_5.dmg wich is running fine.
then trying gnuradio-companion --> sh: gnuradio-companion: command not found
find / -name "gnuradio-companion" did not find something to execute
installed:

port install gnuradio @3.6.2_2+grc+python27+qtgui+docs

maybe im overlooking something, or should there be a script or executable named gnuradio-companion?

It looks like +grc requires +swig also (after reviewing the debug output from your variants). I'll add that it as a requirement.

I'm wondering why you don't just choose "+full"? The hardest dependency to be met is Qt, which you already have there with +qtgui.

Fixed in r101526. This change will go live in ~30 minutes; after that, you can do:

sudo port -f uninstall gnuradio
sudo port selfupdate
sudo port install gnuradio +grc +python27 +qtgui +docs

and, gnuradio-companion should now work.

ok, thank you
did sudo port selfupdate and installed Gnuradio +full
port install gnuradio +grc +python27 +qtgui was a suggestion from another ticket
now im a step further:

PS: dont know if that matter, but its a mac mini without screen and keyboard accessed through remote desktop
gqrx still running fine

You probably need to set the DISPLAY environment variable; what does it return by default:

env | grep DISPLAY

Also, if the solution here isn't obvious, please open a new ticket and we'll work with it there since this issue is different than the ticket's issue.

yippie!
had to install x11 first trough /Applications/Utilities/X11.app
maybe this mac mini was too virgin.
Thanks for your patience!

Replying to michaelld@…:

The OS sets DISPLAY for you. You probably do not need to change it.

If desired, you could install X11 using the xorg-server port in MacPorts. Or you can install ​XQuartz which is presumably what you did. They're both the same software, it's just a matter of what method you want to use to install and update it.
