Re: [Discuss-gnuradio] Newbie trying to follow OOT module tutorial

Oh, here's a better link: http://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorial_GNU_Radio_in_C++#424-Step-3-Fleshing-out-the-code

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.

Hi, I'm a complete novice to GNURadio but I'm trying to follow the gnu
tutorial for creating a OOT block.  When I get to the CMake part I keep
getting these error codes.  I'm sure I'm just missing a dependancy or
something simple but I'm also pretty new to RPi too.  I'm trying to create a
project for a university degree and I'm getting a bit stumped.  Any help is
appreciated.
