[Discuss-gnuradio] uhd_fft and other wx stuff does not work...

[Ralph A. Schmid, dk5ras]

Hi,

 

I installed gnuradio master from source on a Kubuntu 14.04 64 bit system, and it appears that all wxgui stuff does not work. What may be the issue here? Gnuradio and uhd build without error, without missing features, but for example uhd_fft gives this output:

 

address@hidden:~/gnuradio/build$ uhd_fft

linux; GNU C++ version 4.8.2; Boost_105400; UHD_003.008.001-42-g8c87a524

I am not a coder, so at the moment I am somehow out of business. Doing this all new from scratch made no difference, all prereqs seem fulfilled, and after two hours of fiddling and poking around the only consequence is to ask here J

 

Thank you for any hint!
