[Discuss-gnuradio] Problem Making and Installing New Block

[Franklin Sands]

I'm trying to write a new block called howto_file_modulator_f to be used in gnu 
radio.  I'm new to programming using autotools and I believe this is where I'm 
having problems.  I found a tutorial for writing a new block here: 
http://www.nd.edu/~jnl/sdr/docs/tutorials/11.html.  I am also using "How to 
Write a Signal Processing Block" article on the Gnu Radio site.  I'm using Gnu 
Radio version 3.0.4 on a machine running Fedora 7.

So first I extracted the tar file into my home directory 
/home/franklin/gr-howto-write-a-block-3.0.4/.  I will call this topdir.  I 
wrote the c++ .h and .cc files and put them in the topdir/src/lib folder.  I 
modified the howto.i file by putting "#include "howto_file_modulator_f.h"" in 
the include section and added this at the end of the file:

GR_SWIG_BLOCK_MAGIC(howto,file_modulator_f.h);

howto_file_modulator_f_sptr howto_make_file_modulator_f ();

I also added a class declaration with the public member functions, the private 
constructor, and public destructor.  

Then I modifed topdir/src/lib/Makefile.am.  howto_file_modulator_f.cc was added 
to _howto_la_SOURCES list.  howto_file_modulator_f.h was added to the 
grinclude_HEADERS list.  

topdir/configure.ac and topdir/src/python/Makefile.am were not modified.  
Configure.ac was left alone because I was still installing everything under the 
howto module.  The last Makefile.am was not modified because I haven't created 
any quality assurance test code yet.

./configure still seems to work find but I get a long list of errors when I try 
to make the block.  I have attached a file with the command line output.  

Any idea on what I forgot to do or didn't do right?  I can send the c++ code if 
it will be helpful in trouble shooting this.

Thanks,

Keith
