Re: [Discuss-gnuradio] howto module ... please help
Eric, Thanks for getting back to me. I rewrote the code as suggested (thanks for the tip) and still get the SEGFAULT. I'm not sure how to check if I have multiple installations. I have folders titled "gnuradio" in the following locations: /home/mike /home/mike/gnuradio/gnuradio-core/src/python /home/mike/gnuradio/gruel/src/scheme /etc /usr/include /usr/lib/python2.6/dist-packages /usr/share /usr/share/doc /usr/local/etc /usr/local/include /usr/local/lib/python2.6/dist-packages /usr/local/share /usr/local/libexec and the gnuradio-core folder is only located in /home/mike/gnuradio Does that make it seem like I have multiple installations (and if so, which ones should i remove)? How else could I find out?

It doesn't SEGFAULT for me leading me to think that you have a hosed- up GNU Radio installation on your system. Is there any chance that you've got more than one installation? Perhaps one from a .deb or .rpm and one from source? If so, uninstall the packaged one. Also, what you really want is something like the code below. Otherwise the dst.data() is always empty, since the graph hasn't run when you first print it out.

Hello, I posted this a week ago and received no response. Any comments or suggestions would be greatly appreciate. I recently got python programs to successfully import the howto module, but I cannot use the functions: Python code: #!/usr/bin/env python from gnuradio import gr import howto class my_top_block(gr.top_block): def __init__(self): gr.top_block.__init__(self) src_nums = (4, 5, 6) src = gr.vector_source_f (src_nums) sqr = howto.square_ff () dst = gr.vector_sink_f () self.connect (src, sqr) self.connect (sqr, dst) print "src: ", src print "sqr: ", sqr print "dst.data: ", dst.data() if __name__ == '__main__': my_top_block().run() Output: src: sqr: dst.data: () Segmentation fault Thanks, Mike ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
