Hi all: I am new to this group and I am GNU radios to listen to a band of frequencies and see the spectrum by computing the FFT. The following command
./usrp_fft.py -R B -f 1e6 >> data_fft_1_2.dat results in the following error.. Should I have some display settings to avoid this? And why do I get a segmentation fault? Traceback (most recent call last): File "./usrp_fft.py", line 251, in ? main () File "./usrp_fft.py", line 247, in main app = stdgui.stdapp(app_flow_graph, "USRP FFT", nstatus=1) File "/usr/local/lib/python2.4/site-packages/gnuradio/wxgui/stdgui.py", line 36, in __init__ wx.App.__init__ (self, redirect=False) File "/usr/lib/python2.4/site-packages/wx-2.6-gtk2-unicode /wx/_core.py", line 7700, in __init__ self._BootstrapApp() File "/usr/lib/python2.4/site-packages/wx-2.6-gtk2-unicode/wx/_core.py", line 7352, in _BootstrapApp return _core_.PyApp__BootstrapApp(*args, **kwargs) SystemError: wxEntryStart failed, unable to initialize wxWidgets! (Is DISPLAY set properly?) Segmentation fault _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
