John Ackermann N8UR jra at febo.comThank you, Fabian! I followed your advice and was able to successfully build the full Gnuradio system. Using an RTL-SDR.com dongle, I am able to run osmocom_fft with expected results. However, on exiting osmocom_fft (or other oscmocom programs) I get a lengthy set of error messages. I also saw this with my earlier attempts to work around the build problem. I wonder if there is another issue. Here is a screenshot showing the beginning of the console output. Do you know what might be causing this?
