Re: [Discuss-gnuradio] Segmentation fault

Hi Ekko,

really, use GDB, not Pdb. Just "run" your program, than "backtrace"; stepping through it is really really tedious, and isn't really extremely helpful unless you know intimately where to look.

As Tom mentioned, the debugging (and the GDB) tutorial will be helpful.

Best regards,
Marcus

hi marcus

i use the gdb as you said,the i debug the python file again

run the fie step by step 

i found that the there is some problem with 'channel model',just like

​ you can see that 

self.channels_channel_model_0 = channels.channel_model( 

function is init the channel model block

and the noise_voltage =0.0001 ,frequency_offset=0 and so on is the parameter of 'channel model'

after the parameter is inited,the program should call the 

 Subroutine to pass this parameters,but you can see that the program aborted,

then i use command p to view the value of self.channels_channel_model_0,but i got the output

there is no attribute of this ,in other words 

i think that there is some problem with the channel model in the pre-installed gnuradio.

hope you can confirm this problem
