Correct - gnuradio currently needs qt4 to build. But Debian already built gnuradio for you. Note, there are gnuradio applications - like gqrx or inspectrum which need qt5 installed - which isn't a problem because they're linking to the gnuradio libraries and providing their own gni software - and not linking to libgnuradio-qtgui. Check to see if gnuradio-companion works. You'll have the choice of either using WX or QT widgets - QT is recommended since WX will be removed in the next major release. -- Cinaed > > With thanks for the wonderful packages your communities are providing, > Adrian (YO8RZZ) > > [1] https://github.com/kantooon/qradiolink > [2] https://www.youtube.com/watch?v=93nWWASt5a4 > > > > > > > _______________________________________________ > Discuss-gnuradio mailing list > Discuss-gnuradio@gnu.org > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio > _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
