Re: [Discuss-gnuradio] Segmentation fault

Ekko,

using Putty isn't really hard, compared to doing SDR; it has solid copy and paste functionality.

Also, you should at this point really start using a Linux on your host PC. If you're developing C++ for the E310, you should really be starting to use the SDK, which works under linux. This makes twice as much sense as you're currently having trouble using the linux system on the E310 -- you will need to get used to linux, and that's much easier if you do it with a modern Linux distribution on your PC.

Best regards,
Marcus

write the block my_qpsk_demod,

use cmake ../

make 

make install 

to compile the block

you are right ,there is 180 message of command 'bt'

i only show you the nine of these,

marcus said that SIGILL is not the segfault.

I think there's some lines missing from your screenshot. Instead of a screenshot can you just copy and paste all of the text that you get out? Also, it looks like you're in the middle of the tutorials. Does the flowgraph contain any blocks that you compiled in addition to what came on the E310 image? If so, how did you compile them.
