Homebrew-core: gnuradio package no longer installs gnuradio-companion GUI tool

[axman6]

• [x] Ran brew update and retried your prior step?
• [x] Ran brew doctor, fixed as many issues as possible and retried your prior step?
• [x] Confirmed this is problem with specific formulae and not Homebrew/brew? If it's a general Homebrew/brew problem please file this issue at https://github.com/Homebrew/brew/issues/new

Bug reports:

After installing gnuradio, the gnuradio-companion executable is no longer installed. gnuradio-config-info is installed (and confirmed to be installed when uninstalling this package).

### brew gist-logs gnuradio

$ brew gist-logs gnuradio
Error: No logs.

Yup, this is due to the retirement of Qt 4 from Homebrew.

See https://github.com/gnuradio/gnuradio/issues/1090, which will eventually rectify the situation.

[axman6]

Thanks for the heads up. Glad there's a good reason and not someone just forgetting to compile with a flag that builds the GUI.

[ilovezfs]

@axman6 hehe yeah. If you need an immediate solution: https://github.com/cartr/homebrew-qt4 + the old formula will get you back up and running.

[HughAndersonNUS]

@ilovezfs - can you just clarify a little?

I did:
brew tap cartr/qt4
brew tap-pin cartr/qt4
brew install qt
(which worked fine). But then if I installed gnuradio again it did not include gnuradio-companion. What did you mean by "the old formula"?

Cheers Hugh

git --no-pager show 4004e52cd4976e5753d540ad26979e96cf364e3e^:Formula/gnuradio.rb

[HughAndersonNUS]

OK - so I have the new formula. But when I try to run it, it does this:

Hughs-MacBook-Pro:homebrew-core hugh$ brew install ./gnuradio.rb 
Error: Operation already in progress for qt
Another active Homebrew process is already using qt.
Please wait for it to finish or terminate it to continue.

If I delete all the lock files in /usr/local/var/homebrew/locks, it still happens. There is no other brew process running. Is there some other dependency that is causing a conflict maybe?

[HughAndersonNUS]

I'll answer my own question. I'm not sure if this is what I should do, but I changed the line in gnuradio.rb that said
depends_on "qt"
to
depends_on "cartr/homebrew-qt4/qt"
And then it works... Thanks to @ilovezfs ...

.... but .... I still have issues, that appear to be related to python bindings. When I try to run gnuradio-companion, it complains about swig (Sigh...):

Traceback (most recent call last):
  File "/Users/hugh/qpsk_tx_uhd.py", line 20, in <module>

    __import__(name)
ImportError: No module named _blocks_swig0

Back to the drawing board. It appears to be something to do with boost:

ImportError: dlopen(./_blocks_swig0.so, 2): Symbol not found: __ZN5boost11this_thread5hiden11sleep_untilERK8timespec

Could you (package maintainers) please add a notice (e.g. under "Caveats") to the current gnuradio Formula that GRC is not included, as I just wasted some time to figure this out and to me the Formula is pretty useless. Thanks.

Hopefully, the gnuradio-for-mac-without-macports may work for you
