Building gr-osmosdr from source fails

Hi, I'm having trouble installing gr-osmosdr via pybombs so I checked out the master branch from git.osmocom.org/gr-osmosdr, but building still fails with the same error: > gregor@gregor-laptop ~/temp/gr-osmosdr/build $ cmake ../ > -- Build type not specified: defaulting to release. > -- Extracting version information from git describe... > -- Configuring Boost C++ Libraries... > -- Boost version: 1.58.0 > -- Found the following Boost libraries: > -- thread > -- system > -- chrono > -- date_time > -- atomic > -- Found PkgConfig: /usr/bin/pkg-config (found version "0.29.1") > Checking for GNU Radio Module: RUNTIME > -- Checking for module 'gnuradio-runtime' > -- Found gnuradio-runtime, version 3.7.13.4 > * INCLUDES=/home/gregor/prefix/include > * > LIBS=/home/gregor/prefix/lib/libgnuradio-runtime.so;/home/gregor/prefix/lib/libgnuradio-pmt.so;/usr/lib/liblog4cpp.so > -- Found GNURADIO_RUNTIME: > /home/gregor/prefix/lib/libgnuradio-runtime.so;/home/gregor/prefix/lib/libgnuradio-pmt.so;/usr/lib/liblog4cpp.so > > GNURADIO_RUNTIME_FOUND = TRUE > Checking for GNU Radio Module: BLOCKS > -- Checking for module 'gnuradio-blocks' > -- Found gnuradio-blocks, version 3.7.13.4 > * INCLUDES=/home/gregor/prefix/include > * > LIBS=/home/gregor/prefix/lib/libgnuradio-blocks.so;/home/gregor/prefix/lib/libgnuradio-runtime.so;/home/gregor/prefix/lib/libgnuradio-pmt.so;/usr/lib/liblog4cpp.so > -- Found GNURADIO_BLOCKS: > /home/gregor/prefix/lib/libgnuradio-blocks.so;/home/gregor/prefix/lib/libgnuradio-runtime.so;/home/gregor/prefix/lib/libgnuradio-pmt.so;/usr/lib/liblog4cpp.so > > GNURADIO_BLOCKS_FOUND = TRUE > Checking for GNU Radio Module: PMT > -- Checking for module 'gnuradio-runtime' > -- Found gnuradio-runtime, version 3.7.13.4 > * INCLUDES=/home/gregor/prefix/include > * > LIBS=/home/gregor/prefix/lib/libgnuradio-runtime.so;/home/gregor/prefix/lib/libgnuradio-pmt.so;/usr/lib/liblog4cpp.so > -- Found GNURADIO_PMT: > /home/gregor/prefix/lib/libgnuradio-runtime.so;/home/gregor/prefix/lib/libgnuradio-pmt.so;/usr/lib/liblog4cpp.so > > GNURADIO_PMT_FOUND = TRUE > -- Checking for module 'gnuradio-iqbalance' > -- Found gnuradio-iqbalance, version 0 > -- Found GNURADIO_IQBALANCE: > /home/gregor/prefix/lib/libgnuradio-iqbalance.so > -- Found UHD: /home/gregor/prefix/lib/libuhd.so > -- Checking for module 'gnuradio-uhd' > -- Found gnuradio-uhd, version 3.7.13.4 > -- Found gnuradio-uhd: /home/gregor/prefix/include, > /home/gregor/prefix/lib/libgnuradio-uhd.so > -- Found GNURADIO_UHD: /home/gregor/prefix/lib/libgnuradio-uhd.so > -- Checking for module 'gnuradio-fcd' > -- Found gnuradio-fcd, version 3.7.13.4 > -- Found gnuradio-fcd: /home/gregor/prefix/include, > /home/gregor/prefix/lib/libgnuradio-fcd.so > -- Found GNURADIO_FCD: /home/gregor/prefix/lib/libgnuradio-fcd.so > -- Checking for module 'gnuradio-fcdproplus' > -- No package 'gnuradio-fcdproplus' found > -- gnuradio-fcdproplus not found. > -- Could NOT find GNURADIO_FCDPP (missing: GNURADIO_FCDPP_LIBRARIES > GNURADIO_FCDPP_INCLUDE_DIRS) > -- Checking for module 'libosmosdr' > -- Found libosmosdr, version > -- Found libosmosdr: /home/gregor/prefix/include, > /home/gregor/prefix/lib/libosmosdr.so > -- Checking for module 'librtlsdr' > -- Found librtlsdr, version 0.6.0-2-gf68bb > -- Found librtlsdr: /home/gregor/prefix/include, > /home/gregor/prefix/lib/librtlsdr.so > -- Checking for module 'libmirisdr' > -- No package 'libmirisdr' found > -- libmirisdr not found. > -- Checking for module 'libhackrf' > -- Found libhackrf, version 0.5 > -- Found LIBHACKRF: /home/gregor/prefix/lib/libhackrf.so > -- Checking for module 'libairspy' > -- Found libairspy, version 1.0 > -- Found LIBAIRSPY: /home/gregor/prefix/lib/libairspy.so > -- Checking for module 'volk' > -- Found volk, version 1.4 > -- Found VOLK: /home/gregor/prefix/lib/libvolk.so > -- Checking for module 'libbladeRF' > -- Found libbladeRF, version 2.2.0-git-e4bf84a > -- Found libbladeRF: /home/gregor/prefix/include, > /home/gregor/prefix/lib/libbladeRF.so > -- Checking for module 'libfreesrp' > -- No package 'libfreesrp' found > -- libfreesrp not found. > -- Found Doxygen: /usr/bin/doxygen (found version "1.8.11") > -- Found PythonLibs: /usr/lib/x86_64-linux-gnu/libpython2.7.so (found > suitable version "2.7.12", minimum required is "2") > -- > -- Checking for module SWIG > -- Found SWIG version 3.0.8. > -- Found SWIG: /usr/bin/swig3.0 > -- Minimum SWIG version required is 1.3.31 > -- > -- The build system will automatically enable all components. > -- Use -DENABLE_DEFAULT=OFF to disable components by default. > -- > -- Configuring Python support support... > -- Dependency PYTHONLIBS_FOUND = TRUE > -- Dependency SWIG_FOUND = TRUE > -- Dependency SWIG_VERSION_CHECK = TRUE > -- Enabling Python support support. > -- Override with -DENABLE_PYTHON=ON/OFF > -- > -- Configuring high resolution timing... > -- Performing Test HAVE_CLOCK_GETTIME > -- Performing Test HAVE_CLOCK_GETTIME -

rtl_map project [RTL-SDR]
by KeyLo99 28 Jan '19

28 Jan '19

I'm a RTL-SDR researcher and DSP learner currently working on a project for properly figuring RTL2832 and I/Q fundamentals out. The project is about reading raw I/Q samples, processing samples and creating FFT graph from them. I tried to explain what I'm doing in detail with comment lines. I'm hoping that I will be helpful to RTL-SDR beginners with this rtl_map [C] project. Another purpose of the rtl_map project is making a frequency scanner application for signal security researches. Another information about the project, installation instructions and example usages exist at the GitHub repository. https://github.com/KeyLo99/rtl_map

gr-osmosdr and libbladerf compile failures
by Harald Welte 27 Jan '19

27 Jan '19

Hi Rey + Robert, I've just also been hit by a bug that was already filed some 5 months ago in the osmocom.org bug tracker: http://osmocom.org/issues/3512 It seems that the bladerf support to gr-osmosdr added in 2018 unconditionally accepts any libbladerf version installed and subseequently enables the support for it, only then to fails to compile as it actually appears to require a minimum version of 2.0.0 for which it doesn't check during the cmake step. I don't know much about Cmake and hence it would be great if you as the authors of the related code could find a minute to ensure that gr-osmosdr will simply not try to build bladerf support if the version of libbladerf is too old. I'm aware that I can of course manually disable bladerf support, but that's more a work-around than a proper solution, IMHO. Thanks in advance!

advice on ham radio operation
by Joseph Hutchins 25 Jan '19

25 Jan '19

Hi, after I make the appropriate bandpass filters, I wanted to attach the device to an antenna and try some SSB HF, maybe 10 or 20 meter band. I noticed there are no SSB examples and so I will need to write the program myself. I was contacting to ask if there is any reason that the examples use standalone binaries to interact with the fresco chip rather than writing a library for gnuradio. Did something about gnuradio make the fresco's integration with it impractical? Would I be better off proceeding by writing a gnuradio block for the Fresco sink or a standalone SSB-tx program? The novelty of demonstrating that such a cheap setup is feasible really appeals to me. Thanks, Joseph Hutchins

gr-osmosdr / no tagged versions since 2014
by Harald Welte 08 Jan '19

08 Jan '19

Hi! today I discovered that the gr-osmosdr package in debian unstable contains a whooping list of 96 patches. This is due to the fact that since November 2014 there hasn't been any tagged versions in the repository. I'd like to suggest to tag releases a bit more often. @horizon: What about jumping to 1.0.0 right away?

RTL_FM on the fly updates
by Mark Russell 08 Jan '19

08 Jan '19

Good evening - I am trying to make modifications to rtl_fm so that I can change frequencies, gains, modulation types, and squelch values on the fly (and thus avoiding a restart). Its unclear to me what functions need to be called in order to apply changes to the sdr device so that I can do the above. The rtl_fm code isnt documented so I dont have much to go off of... GQRX doesnt run reliably on any RPi3's I've tried so I hoping to use a modified rtl_fm in its place. Any help would be appreciated. Thanks :)
