Re: [Discuss-gnuradio] Newbie trying to follow OOT module tutorial
Keep reading the tutorial and read the errors. The code that comes out of gr_modtool isn't really valid c++ yet, but it's close. """ /home/pi/gr-howto/lib/square_ff_impl.cc:43:38: error: expected primary-expression before ‘<’ token gr::io_signature::make(<+MIN_IN+>, <+MAX_IN+>, sizeof(<+ITYPE+>)), ^ /home/pi/gr-howto/lib/square_ff_impl.cc:43:40: error: ‘MIN_IN’ was not declared in this scope gr::io_signature::make(<+MIN_IN+>, <+MAX_IN+>, sizeof(<+ITYPE+>)), ^ /home/pi/gr-howto/lib/square_ff_impl.cc:43:47: error: expected primary-expression before ‘>’ token gr::io_signature::make(<+MIN_IN+>, <+MAX_IN+>, sizeof(<+ITYPE+>)), ^ /home/pi/gr-howto/lib/square_ff_impl.cc:43:48: error: expected primary-expression before ‘,’ token gr::io_signature::make(<+MIN_IN+>, <+MAX_IN+>, sizeof(<+ITYPE+>)), """ That's telling you that the code isn't valid C++. It's filler from a template with hints as to what goes there.I also suggest not working off of a raspberry pi immediately. You'll be more comfortable and iterate faster on a laptop or desktop.

Re: [Discuss-gnuradio] Newbie trying to follow OOT module tutorial
Check out http://gnuradio.org/redmine/projects/gnuradio/wiki/BlocksCodingGuide. You'll see that the <+MAX_IN+>, <+MAX_OUT+>, <+MIN_IN+>, <+MIN_OUT+>, <+ITYPE+>, and <+OTYPE+> have all been replaced with actual values. Unless you have multiple inputs and/or outputs you'll replace all of the <+MAX_IN+>, <+MAX_OUT+>, <+MIN_IN+>, <+MIN_OUT+> parts with the number 1. <+ITYPE+>, and <+OTYPE+> are dependent on what your input and output types are for the block. Suppose your block reads in complex values and output floats. In that case you would replace all instances of <+ITYPE+> with gr_complex and all instances of <+OTYPE+> with float. Also make sure that your XML file for the block matches the number of inputs, and outputs as well as the types for each.
