GNU Radio with Jack support

[veso266]

Hi I would like to use this FM IBOC Transmitter https://nuand.com/forums/viewtopic.php?f=8&t=3523 but I can't get GNU Radio to support Jack. I use build-gnuradio install script to install GNU Radio and bladerf on Ubuntu Studio. So anyone know how to install GNU Radio with Jack Support.

When you run CMake to configure GNU Radio, what's the output look like for gr-audio. I did not have jack setup, so I saw something like this:

Code: Select all

-- Configuring gr-audio support...
--   Dependency Boost_FOUND = 1
--   Dependency ENABLE_GNURADIO_RUNTIME = ON
--   Enabling gr-audio support.
--   Override with -DENABLE_GR_AUDIO=ON/OFF
-- Found ALSA 1.0.27.2
-- checking for module 'jack'
--   package 'jack' not found
-- checking for module 'portaudio-2.0'
--   package 'portaudio-2.0' not found
-- checking for module 'comedilib'
--   package 'comedilib' not found

After a quick look at the jack-related packages in my package manager (I still like to use synaptic for this), I see there's a libjack-jackd2-dev package, so I installed that. This appears to have satisifed the CMakeLists.txt for gr-audio:

Code: Select all

-- Configuring gr-audio support...
--   Dependency Boost_FOUND = 1
--   Dependency ENABLE_GNURADIO_RUNTIME = ON
--   Enabling gr-audio support.
--   Override with -DENABLE_GR_AUDIO=ON/OFF
-- Found ALSA 1.0.27.2
-- checking for module 'jack'
--   found jack, version 1.9.10
-- Found jack: /usr/lib/x86_64-linux-gnu/libjack.so
-- checking for module 'portaudio-2.0'
--   package 'portaudio-2.0' not found
-- checking for module 'comedilib'
--   package 'comedilib' not found

I didn't test things out, but perhaps this will give you a good start. If none of this was useful to you, could you perhaps elaborate on your situation?

Thanks

I use this script: http://www.sbrac.org/files/build-gnuradio (I can sit back and relax while script does all the work for me) so I don't know how I can run cmake again? I use Ubuntu Studio which has Jack preinstalled http://ubuntustudio.org/ (So do I still need to install libjack-jackd2-dev?)

PS: Can I run cmake again so that gr-audio will be reinstalled?

Best Regards

Wherever you ran build-gnuradio, you should be able to track down a gnuradio/gr-analog directory. There may be a build directory within that -- there will be a CMakeCache.txt file in that build directory. From there you should be able to re-run cmake ../ && make && sudo make install.

Generally, the -dev packages install the header files that you'll need when building against libraries. You can take a look at what jack packages are installed, and look for an associated -dev package.

OK so when I do that what is the easiest way to check if gr-audio-jack was installed and if gnuradio support jack?

[jynik]

When you run CMake in the gr-audio build directory, you'll see some output like I showed in my earlier post. Note the "found jack..." text -- that's what's going to tell you that it's ready to be re-compiled and re-installed with jack support.

What do you think what is better build-gnuradio script or PyBOMBS and why?

[jynik]

PyBOMBS is the new GR install management system, so if you're not comfortable with build-gnuradio, go with PyBOMBS.

I suspect you might find PyBOMBS a bit easier to navigate and work with.

when i go into gnuradio/gr-analog there is no build directory inside so I created it and run cmake ../ but error accour

My mistake. The build is done back in the gnuradio/ directory. (Normally, I do it in a build/ directory within it).

For what it's worth, the build directory will contain a CMakeCache.txt as well as a install_manifest.txt (if you did a make install).

[veso266]

To recall what I did (if some people have trouble)

1. download build-gnuradio script, chmod a+x and run it
2. Wait script that it wil finish its magic
3. go to Synaptic (sudo synaptic) and install libjack-jackd2-dev ) (optionaly I do sudo apt-get install Jack)
4. go to gnuradio directory (script will put the files where it is) and do cmake ../ && make && sudo make install
5. go to /usr/local/etc/gnuradio/conf.d and find gr-audio.conf file it shoud look like this

Code: Select all

# This file contains system wide configuration data for GNU Radio.
	
# You may override any setting on a per-user basis by editing
# ~/.gnuradio/config.conf
# specify which audio module to load, or use "auto" to have the system
# select one.  Valid choices depend on your OS and which modules
# you've installed, but typically include:
# auto, alsa, oss, portaudio, jack, osx, windows
	
	
[audio]
	

audio_module = auto

6. change (from auto to jack) audio_module = jack
7 install gr-drm (I must install libdrm from Synaptic before compiling it)
8. Enyoy (you can download FMDigital Flowgraph mentiond above here: http://sourceforge.net/projects/fmdigital/

the only trouble I had is getting RDS aut of flowgraph maybe my jack setting aren't right
