Since there are so many tutorials: I like to point people to our Guided Tutorials, which I consider to be the "official" way to get started with GNU Radio, since we pay close attention to keeping these up-to-date and correct etc: https://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorials > > However, I have some problems: I cannot save the flow-chart nor > execute it. I have a blind guess (having my last name): You have entered a special character in the author field? I recently patched that, but that fix is not in 3.7.5. If it's not, we'll have a few more things we can look at: > When I start GRC and save the first screen (only variable + option > squares) it's OK.

Hm, are you using the same GUI widgets as in your options->build options? To explain: If you use the Qt frequency sink, you will have to make sure your build options is set to Qt; the same applies for WX Gui and the Wx build option. You cannot mix those. I recommend using Qt GUI. It's actively developed, and in my opinion, feature-richer. Also, in my experience, it performs much better. > There are no apparent error (all is black and the STOP sign is not on) > and I counter-checked dozen of times, directly and against similar > tutorials. > > No error arise during saving and execute phases, but nothing happens. > > It's probably something completely obvious, but I cannot figure what. > It worked and suddenly did not work! > Any hint would be welcome! > > I use version 3.7.5 (this is the one which has been automatically > installed with "apt-get install"). > OS is the last DEBIAN with KDE desk. > That sounds alright. > Have all a nice WE. > Best regards, Marcus _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
