Hi @michaelld it seems like gr-osmosdr has something error

info:

OSX 10.13.2
mac port 2.4.3
gnuradio 3.7.12.0
gr-osmosdr @20170611_6+airspy+bladeRF+docs+fcdproplus+hackrf+rtlsdr+sdrplay+soapysdr+swig+uhd (active)

port info gr-osmosdr
gr-osmosdr @20170611_6 (science, comms)
Variants:             [+]airspy, [+]bladeRF, debug, [+]docs, [+]fcdproplus, [+]hackrf, [+]rtlsdr, [+]sdrplay, [+]soapysdr, [+]swig, [+]uhd,
                      universal

Description:          Includes OSMO SDR support GNU Radio source and sink blocks in C++, Python, and GNU Radio Companion (grc). This port
                      also offers a wrapper functionality for the FunCube Dongle, FunCube Dongle Pro+, HackRF, RFSpace, Ettus UHD, and
                      rtl-sdr radios and software. By using gr-osmosdr source you can take advantage of a common software API in your
                      applications independent of the underlying radio hardware. This port is kept up with the gr-osmosdr GIT 'master'
                      branch, which is typically updated weekly to monthly, providing compatibility with GNU Radio release 3.7 API: the
                      gnuradio and gnuradio-devel ports.

what does port installed gnuradio-devel return?

[michaelld]

please note that gr-wxgui is going away with the 3.8 release, and there are enough issues with it (and gr-qtgui works so much better & is roughly a drop-in replacement) that I disabled auto-install of gr-wxgui with the gnuradio-devel port. You can still try to install it via sudo port install gnuradio-devel +wxgui.

[cn0xroot]

port installed gnuradio-devel
The following ports are currently installed:
  gnuradio-devel @20180405_1+docs+grc+jack+log4cpp+logging+portaudio+qtgui+sdl+swig+uhd+wavelet+zeromq (active)

[michaelld]

yeah so you have the default gnuradio-devel install. try installing it with +wxgui.

BTW> can you please attach the commandline & resulting output from whatever you did that resulted in the gr-wxgui required error?

[cn0xroot]

when i use osmcom_fft,i get the error

osmocom_fft -f 315e6 -s 2e6
Error importing GNU Radio's wxgui. Please make sure gr-wxgui is installed.
osmocom_fft --help
Error importing GNU Radio's wxgui. Please make sure gr-wxgui is installed.

and i have some grc file , it base on wxgui.

[michaelld]

Ah; OK that make sense. Hmmm .. yeah I'll need to fix issue that somewhere in gr-osmosdr or gnuradio [-devel] ... will add it to my queue & think deep thoughts ...

[michaelld]

I actually have gnuradio-devel +wxgui installed and it works; so does gr-osmosdr then & osmosdr_fft too. Go figure.

[cn0xroot]

Thanks for your quickly replay,i think it will work fine when i have gnuradio-devel +wxgui.
GNURaddio is a very nice project!
Have a nice day.

[michaelld]

Glad to help. Please report back here your success in getting gnuradio-devel +wxgui to install. You might have to rebuild gr-osmosdr with the updated GR; might not too. Try your osmosdr_fft & see if it works after the GR update; it very well might in which case you're good to go.

[cn0xroot]

oh,i meet another error：

osmocom_fft

This kind of discussion is better suited for the mailing list, it is not an issue with the codebase as far as I can tell. Closing now.

I hate necro-posting, but thought I would anyway in case it's of use to the next person that comes along...

This issue came about for me when I went to install gr-osmosdr via macports, without having first installed gnu radio (I figured the port for gr-osmosdr would handle the dependencies correctly - which it didn't seem to for me on Mac OSX Mojave).

The installation for gr-osmosdr via macports seems to depend on the user having already run:

sudo port install gnuradio +grc +swig +wxgui +qtgui
I did not need to re-install gr-osmosdr after installing gnuradio

Hopefully not off-topic:
I tried to install gr-osmosdr through Macports (clean!).
